Sleep: yes, you really do still need it!
We asked you how much sleep you usually get, and got the above-pictured, below-described set of responses:
- A little of a third of all respondents selected the option “< 7 hours”
- However, because respondents also selected options such as < 6 hours, < 5 hours, and < 4 hours, so if we include those in the tally, the actual total percentage of respondents who reported getting under 7 hours, is actually more like 62%, or just under two thirds of all respondents.
- Nine respondents, which was about 5% of the total, reported usually getting under 4 hours sleep
- A little over quarter of respondents reported usually getting between 7 and 8 hours sleep
- Fifteen respondents, which was a little under 10% of the total, reported usually getting between 8 and 9 hours of sleep
- Three respondents, which was a little under 2% of the total, reported getting over 9 hours of sleep
- In terms of the classic “you should get 7–9 hours sleep”, approximately a third of respondents reported getting this amount.
You need to get 7–9 hours sleep: True or False?
True! Unless you have a (rare!) mutated ADRB1 gene, which reduces that.
The way to know whether you have this, without genomic testing to know for sure, is: do you regularly get under 6.5 hours sleep, and yet continue to go through life bright-eyed and bushy-tailed? If so, you probably have that gene. If you experience daytime fatigue, brain fog, and restlessness, you probably don’t.
About that mutated ADRB1 gene:
NIH | Gene identified in people who need little sleep
Quality of sleep matters as much as duration, and a lot of studies use the “RU-Sated” framework, which assesses six key dimensions of sleep that have been consistently associated with better health outcomes. These are:
- regularity / usual hours
- satisfaction with sleep
- alertness during waking hours
- timing of sleep
- efficiency of sleep
- duration of sleep
But, that doesn’t mean that you can skimp on the last one if the others are in order. In fact, getting a good 7 hours sleep can reduce your risk of getting a cold by three or four times (compared with six or fewer hours):
Behaviorally Assessed Sleep and Susceptibility to the Common Cold
^This study was about the common cold, but you may be aware there are more serious respiratory viruses freely available, and you don’t want those, either.
Napping is good for the health: True or False?
True or False, depending on how you’re doing it!
If you’re trying to do it to sleep less in total (per polyphasic sleep scheduling), then no, this will not work in any sustainable fashion and will be ruinous to the health. We did a Mythbusting Friday special on specifically this, a while back:
Could Just Two Hours Sleep Per Day Be Enough?
PS: you might remember Betteridge’s Law of Headlines
If you’re doing it as a energy-boosting supplement to a reasonable night’s sleep, napping can indeed be beneficial to the health, and can give benefits such as:
- Increased alertness
- Helps with learning
- Improved memory
- Boost to immunity
- Enhance athletic performance
However! There is still a right and a wrong way to go about it, and we wrote about this previously, for a Saturday Life Hacks edition of 10almonds:
How To Nap Like A Pro (No More “Sleep Hangovers”!)
As we get older, we need less sleep: True or False
False, with one small caveat.
The small caveat: children and adolescents need 9–12 hours sleep because, uncredited as it goes, they are doing some seriously impressive bodybuilding, and that is exhausting to the body. So, an adult (with a normal lifestyle, who is not a bodybuilder) will tend to need less sleep than a child/adolescent.
But, the statement “As we get older, we need less sleep” is generally taken to mean “People in the 65+ age bracket need less sleep than younger adults”, and this popular myth is based on anecdotal observational evidence: older people tend to sleep less (as our survey above shows! For any who aren’t aware, our readership is heavily weighted towards the 60+ demographic), and still continue functioning, after all.
Just because we survive something with a degree of resilience doesn’t mean it’s good for us.
In fact, there can be serious health risks from not getting enough sleep in later years, for example:
Sleep deficiency promotes Alzheimer’s disease development and progression
Want to get better sleep?
What gets measured, gets done. Sleep tracking apps can be a really good tool for getting one’s sleep on a healthier track. We compared and contrasted some popular ones:

We’re only using a fraction of health workers’ skills. This needs to change
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Roles of health professionals are still unfortunately often stuck in the past. That is, before the shift of education of nurses and other health professionals into universities in the 1980s. So many are still not working to their full scope of practice.
There has been some expansion of roles in recent years – including pharmacists prescribing (under limited circumstances) and administering a wider range of vaccinations.
But the recently released paper from an independent Commonwealth review on health workers’ “scope of practice” identifies the myriad of barriers preventing Australians from fully benefiting from health professionals’ skills.
These include workforce design (who does what, where and how roles interact), legislation and regulation (which often differs according to jurisdiction), and how health workers are funded and paid.
There is no simple quick fix for this type of reform. But we now have a sensible pathway to improve access to care, using all health professionals appropriately.
A new vision for general practice
I recently had a COVID booster. To do this, I logged onto my general practice’s website, answered the question about what I wanted, booked an appointment with the practice nurse that afternoon, got jabbed, was bulk-billed, sat down for a while, and then went home. Nothing remarkable at all about that.
But that interaction required a host of facilitating factors. The Victorian government regulates whether nurses can provide vaccinations, and what additional training the nurse requires. The Commonwealth government has allowed the practice to be paid by Medicare for the nurse’s work. The venture capitalist practice owner has done the sums and decided allocating a room to a practice nurse is economically rational.
The future of primary care is one involving more use of the range of health professionals, in addition to GPs.
It would be good if my general practice also had a physiotherapist, who I could see if I had back pain without seeing the GP, but there is no Medicare rebate for this. This arrangement would need both health professionals to have access to my health record. There also needs to be trust and good communication between the two when the physio might think the GP needs to be alerted to any issues.
This vision is one of integrated primary care, with health professionals working in a team. The nurse should be able to do more than vaccination and checking vital signs. Do I really need to see the GP every time I need a prescription renewed for my regular medication? This is the nub of the “scope of practice” issue.
How about pharmacists?
An integrated future is not the only future on the table. Pharmacy owners especially have argued that pharmacists should be able to practise independently of GPs, prescribing a limited range of medications and dispensing them.
This will inevitably reduce continuity of care and potentially create risks if the GP is not aware of what other medications a patient is using.
But a greater role for pharmacists has benefits for patients. It is often easier and cheaper for the patient to see a pharmacist, especially as bulk billing rates fall, and this is one of the reasons why independent pharmacist prescribing is gaining traction.
It’s often easier for a patient to see a pharmacist than a GP. PeopleImages.com – Yuri A/Shutterstock Every five years or so the government negotiates an agreement with the Pharmacy Guild, the organisation of pharmacy owners, about how much pharmacies will be paid for dispensing medications and other services. These agreements are called “Community Pharmacy Agreements”. Paying pharmacists independent prescribing may be part of the next agreement, the details of which are currently being negotiated.
GPs don’t like competition from this new source, even though there will be plenty of work around for GPs into the foreseeable future. So their organisations highlight the risks of these changes, reopening centuries old turf wars dressed up as concerns about safety and risk.
Who pays for all this?
Funding is at the heart of disputes about scope of practice. As with many policy debates, there is merit on both sides.
Clearly the government must increase its support for comprehensive general practice. Existing funding of fee-for-service medical benefits payments must be redesigned and supplemented by payments that allow practices to engage a range of other health professionals to create health-care teams.
This should be the principal direction of primary care reform, and the final report of the scope of practice review should make that clear. It must focus on the overall goal of better primary care, rather than simply the aspirations of individual health professionals, and working to a professional’s full scope of practice in a team, not a professional silo.
In parallel, governments – state and federal – must ensure all health professionals are used to their best of their abilities. It is a waste to have highly educated professionals not using their skills fully. New funding arrangements should facilitate better access to care from all appropriately qualified health professionals.
In the case of prescribing, it is possible to reconcile the aspirations of pharmacists and the concerns of GPs. New arrangements could be that pharmacists can only renew medications if they have agreements with the GP and there is good communication between them. This may be easier in rural and suburban areas, where the pharmacists are better known to the GPs.
The second issues paper points to the complexity of achieving scope of practice reforms. However, it also sets out a sensible path to improve access to care using all health professionals appropriately.

The Telomere Effect – by Dr. Elizabeth Blackburn and Dr. Elissa Epel

Telomeres can be pretty mystifying to the person with a lay interest in longevity. Beyond “they’re the little caps that sit on the end of your DNA, and longer is better, and when they get short, damage occurs, and aging”, how do they fit into the big picture?
Dr. Elizabeth Blackburn and Dr. Elissa Epel excel at explaining the marvelous world of telomeres…
- how they work
- what affects them
- and how and why
…and the extent to which changes are or aren’t reversible.
For some of us, the ship has sailed on avoiding a lot of early-life damage to our telomeres, and now we have a damage-mitigation task ahead. That’s where the authors get practical.
Indeed, the whole third part of the book is titled “Help Your Body Protect Its Cells“, and indeed covers not just “from now on” protection, but undoing some of the damage already done (yes, telomeres can be lengthened—it gets harder as we get older, but absolutely can be done).
In short: if you’d like to avoid further damage to your telomeres where possible, and reverse some of the damage done already, this book will set you on the right track.

Prolonged Grief: A New Mental Disorder?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
The issue is not whether certain mental conditions are real—they are. It is how we conceptualize them and what we think treating them requires.
The latest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) features a new diagnosis: prolonged grief disorder—used for those who, a year after a loss, still remain incapacitated by it. This addition follows more than a decade of debate. Supporters argued that the addition enables clinicians to provide much-needed help to those afflicted by what one might simply consider a too much of grief, whereas opponents insisted that one mustn’t unduly pathologize grief and reject an increasingly medicalized approach to a condition that they considered part of a normal process of dealing with loss—a process which in some simply takes longer than in others.
By including a condition in a professional classification system, we collectively recognize it as real. Recognizing hitherto unnamed conditions can help remove certain kinds of disadvantages. Miranda Fricker emphasizes this in her discussion of what she dubs hermeneutic injustice: a specific sort of epistemic injustice that affects persons in their capacity as knowers1. Creating terms like ‘post-natal depression’ and ‘sexual harassment’, Fricker argues, filled lacunae in the collectively available hermeneutic resources that existed where names for distinctive kinds of social experience should have been. The absence of such resources, Fricker holds, put those who suffered from such experiences at an epistemic disadvantage: they lacked the words to talk about them, understand them, and articulate how they were wronged. Simultaneously, such absences prevented wrong-doers from properly understanding and facing the harm they were inflicting—e.g. those who would ridicule or scold mothers of newborns for not being happier or those who would either actively engage in sexual harassment or (knowingly or not) support the societal structures that helped make it seem as if it was something women just had to put up with.
For Fricker, the hermeneutical disadvantage faced by those who suffer from an as-of-yet ill-understood and largely undiagnosed medical condition is not an epistemic injustice. Those so disadvantaged are not excluded from full participation in hermeneutic practices, or at least not through mechanisms of social coercion that arise due to some structural identity prejudice. They are not, in other words, hermeneutically marginalized, which for Fricker, is an essential characteristic of epistemic injustice. Instead, their situation is simply one of “circumstantial epistemic bad luck”2. Still, Fricker, too, can agree that providing labels for ill-understood conditions is valuable. Naming a condition helps raise awareness of it, makes it discursively available and, thus, a possible object of knowledge and understanding. This, in turn, can enable those afflicted by it to understand their experience and give those who care about them another way of nudging them into seeking help.
Surely, if adding prolonged grief disorder to the DSM-5 were merely a matter of recognizing the condition and of facilitating assistance, nobody should have any qualms with it. However, the addition also turns intense grief into a mental disorder—something for whose treatment insurance companies can be billed. With this, significant forces of interest enter the scene. The DSM-5, recall, is mainly consulted by psychiatrists. In contrast to talk-therapists like psychotherapists or psychoanalysts, psychiatrists constitute a highly medicalized profession, in which symptoms—clustered together as syndromes or disorders—are frequently taken to require drugs to treat them. Adding prolonged grief disorder thus heralds the advent of research into various drug-based grief therapies. Ellen Barry of the New York Times confirms this: “naltrexone, a drug used to help treat addiction,” she reports, “is currently in clinical trials as a form of grief therapy”, and we are likely to see a “competition for approval of medicines by the Food and Drug Administration.”3
Adding diagnoses to the DSM-5 creates financial incentives for players in the pharmaceutical industry to develop drugs advertised as providing relief to those so diagnosed. Surely, for various conditions, providing drug-induced relief from severe symptoms is useful, even necessary to enable patients to return to normal levels of functioning. But while drugs may help suppress feelings associated with intense grief, they cannot remove the grief. If all mental illnesses were brain diseases, they might be removed by adhering to some drug regimen or other. Note, however, that ‘mental illness’ is a metaphor that carries the implicit suggestion that just like physical illnesses, mental afflictions, too, are curable by providing the right kind of physical treatment. Unsurprisingly, this metaphor is embraced by those who stand to massively benefit from what profits they may reap from selling a plethora of drugs to those diagnosed with any of what seems like an ever-increasing number of mental disorders. But metaphors have limits. Lou Marinoff, a proponent of philosophical counselling, puts the point aptly:
Those who are dysfunctional by reason of physical illness entirely beyond their control—such as manic-depressives—are helped by medication. For handling that kind of problem, make your first stop a psychiatrist’s office. But if your problem is about identity or values or ethics, your worst bet is to let someone reify a mental illness and write a prescription. There is no pill that will make you find yourself, achieve your goals, or do the right thing.
Much more could be said about the differences between psychotherapy, psychiatry, and the newcomer in the field: philosophical counselling. Interested readers may benefit from consulting Marinoff’s work. Written in a provocative, sometimes alarmist style, it is both entertaining and—if taken with a substantial grain of salt—frequently insightful. My own view is this: from Fricker’s work, we can extract reasons to side with the proponents of adding prolonged grief disorder to the DSM-5. Creating hermeneutic resources that allow us to help raise awareness, promote understanding, and facilitate assistance is commendable. If the addition achieves that, we should welcome it. And yet, one may indeed worry that practitioners are too eager to move from the recognition of a mental condition to the implementation of therapeutic interventions that are based on the assumption that such afflictions must be understood on the model of physical disease. The issue is not whether certain mental conditions are real—they are. It is how we conceptualize them and what we think treating them requires.
No doubt, grief manifests physically. It is, however, not primarily a physical condition—let alone a brain disease. Grief is a distinctive mental condition. Apart from bouts of sadness, its symptoms typically include the loss of orientation or a sense of meaning. To overcome grief, we must come to terms with who we are or can be without the loved one’s physical presence in our life. We may need to reinvent ourselves, figure out how to be better again and whence to derive a new purpose. What is at stake is our sense of identity, our self-worth, and, ultimately, our happiness. Thinking that such issues are best addressed by popping pills puts us on a dangerous path, leading perhaps towards the kind of dystopian society Aldous Huxley imagined in his 1932 novel Brave New World. It does little to help us understand, let alone address, the moral and broader philosophical issues that trouble the bereaved and that lie at the root not just of prolonged grief but, arguably, of many so-called mental illnesses.

No, beetroot isn’t vegetable Viagra. But here’s what else it can do
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Beetroot has been in the news for all the wrong reasons. Supply issues in recent months have seen a shortage of tinned beetroot on Australian supermarket shelves. At one point, a tin was reportedly selling on eBay for more than A$65.
But as supplies increase, we turn our attention to beetroot’s apparent health benefits.
Is beetroot really vegetable Viagra, as UK TV doctor Michael Mosley suggests? What about beetroot’s other apparent health benefits – from reducing your blood pressure to improving your daily workout? Here’s what the science says.
What’s so special about beetroot?
Beetroot – alongside foods such as berries, nuts and leafy greens – is a “superfood”. It contains above-average levels per gram of certain vitamins and minerals.
Beetroot is particularly rich in vitamin B and C, minerals, fibre and antioxidants.
Most cooking methods don’t significantly alter its antioxidant levels. Pressure cooking does, however, lower levels of carotenoid (a type of antioxidant) compared to raw beetroot.
Processing into capsules, powders, chips or juice may affect beetroot’s ability to act as an antioxidant. However, this can vary between products, including between different brands of beetroot juice.
Is beetroot really vegetable Viagra?
The Romans are said to have used beetroot and its juice as an aphrodisiac.
But there’s limited scientific evidence to say beetroot improves your sex life. This does not mean it doesn’t. Rather, the vast number of scientific studies looking at the effect of beetroot have not measured libido or other aspects of sexual health.
How could it work?
When we eat beetroot, chemical reactions involving bacteria and enzymes transform the nitrate in beetroot into nitrite, then to nitric oxide. Nitric oxide helps dilate (widen) blood vessels, potentially improving circulation.
The richest sources of dietary nitric oxide that have been tested in clinical studies are beetroot, rocket and spinach.
Nitric oxide is also thought to support testosterone in its role in controlling blood flow before and during sex in men.
Beetroot’s ability to improve blood flow can benefit the circulatory system of the heart and blood vessels. This may positively impact sexual function, theoretically in men and women.
Therefore, it is reasonable to suggest there could be a modest link between beetroot and preparedness for sex, but don’t expect it to transform your sex life.
What else could it do?
Beetroot has received increasing attention over recent years due to its antioxidant and anti-tumour effect in humans.
Clinical trials have not verified all beetroot’s active ingredients and their effects. However, beetroot may be a potentially helpful treatment for various health issues related to oxidative stress and inflammation, such as cancer and diabetes. The idea is that you can take beetroot supplements or eat extra beetroot alongside your regular medicines (rather than replace them).
There is evidence beetroot juice can help lower systolic blood pressure (the first number in your blood pressure reading) by 2.73-4.81 mmHg (millimetres of mercury, the standard unit of measuring blood pressure) in people with high blood pressure. Some researchers say this reduction is comparable to the effects seen with certain medications and dietary interventions.
Other research finds even people without high blood pressure (but at risk of it) could benefit.
Beetroot may also improve athletic performance. Some studies show small benefits for endurance athletes (who run, swim or cycle long distances). These studies looked at various forms of the food, such as beetroot juice as well as beetroot-based supplements.
How to get more beetroot in your diet
There is scientific evidence to support positive impacts of consuming beetroot in whole, juice and supplement forms. So even if you can’t get hold of tinned beetroot, there are plenty of other ways you can get more beetroot into your diet. You can try:
- raw beetroot – grate raw beetroot and add it to salads or coleslaw, or slice beetroot to use as a crunchy topping for sandwiches or wraps
- cooked beetroot – roast beetroot with olive oil, salt and pepper for a flavour packed side dish. Alternatively, steam beetroot and serve it as a standalone dish or mixed into other dishes
- beetroot juice – make fresh beetroot juice using a juicer. You can combine it with other fruits and vegetables for added flavour. You can also blend raw or cooked beetroot with water and strain to make a juice
- smoothies – add beetroot to your favourite smoothie. It pairs well with fruits such as berries, apples and oranges
- soups – use beetroot in soups for both flavour and colour. Borscht is a classic beetroot soup, but you can also experiment with other recipes
- pickled beetroot – make pickled beetroot at home, or buy it from the supermarket. This can be a tasty addition to salads or sandwiches
- beetroot hummus – blend cooked beetroot into your homemade hummus for a vibrant and nutritious dip. You can also buy beetroot hummus from the supermarket
- grilled beetroot – slice beetroot and grill it for a smoky flavour
- beetroot chips – slice raw beetroot thinly, toss the slices with olive oil and your favourite seasonings, then bake or dehydrate them to make crispy beetroot chips
- cakes and baked goods – add grated beetroot to muffins, cakes, or brownies for a moist and colourful twist.
You can add beetroot to baked goods. Ekaterina Khoroshilova/Shutterstock Are there any downsides?
Compared to the large number of studies on the beneficial effects of beetroot, there is very little evidence of negative side effects.
If you eat large amounts of beetroot, your urine may turn red or purple (called beeturia). But this is generally harmless.
There have been reports in some countries of beetroot-based dietary supplements contaminated with harmful substances, yet we have not seen this reported in Australia.
What’s the take-home message?
Beetroot may give some modest boost to sex for men and women, likely by helping your circulation. But it’s unlikely to transform your sex life or act as vegetable Viagra. We know there are many contributing factors to sexual wellbeing. Diet is only one.

What is ‘breathwork’? And do I need to do it?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
From “breathwork recipes” to breathing techniques, many social media and health websites are recommending breathwork to reduce stress.
But breathwork is not new. Rather it is the latest in a long history of breathing techniques such as Pranayama from India and qigong from China. Such practices have been used for thousands of years to promote a healthy mind and body.
The benefits can be immediate and obvious. Try taking a deep breath in through your nose and exhaling slowly. Do you feel a little calmer?
So, what’s the difference between the breathing we do to keep us alive and breathwork?
Taras Grebinets/Shutterstock Breathwork is about control
Breathwork is not the same as other mindfulness practices. While the latter focus on observing the breath, breathwork is about controlling inhalation and exhalation.
Normally, breathing happens automatically via messages from the brain, outside our conscious control. But we can control our breath, by directing the movement of our diaphragm and mouth.
The diaphragm is a large muscle that separates our thoracic (chest) and abdominal (belly) cavities. When the diaphragm contracts, it expands the thoracic cavity and pulls air into the lungs.
Controlling how deep, how often, how fast and through what (nose or mouth) we inhale is the crux of breathwork, from fire breathing to the humming bee breath.
Breathwork can calm or excite
Even small bits of breathwork can have physical and mental health benefits and complete the stress cycle to avoid burnout.
Calming breathwork includes diaphragmatic (belly) breathing, slow breathing, pausing between breaths, and specifically slowing down the exhale.
In diaphragmatic breathing, you consciously contract your diaphragm down into your abdomen to inhale. This pushes your belly outwards and makes your breathing deeper and slower.
You can also slow the breath by doing:
- box breathing (count to four for each of four steps: breathe in, hold, breathe out, hold), or
- coherent breathing (controlled slow breathing of five or six breaths per minute), or
- alternate nostril breathing (close the left nostril and breathe in slowly through the right nostril, then close the right nostril and breathe out slowly through the left nostril, then repeat the opposite way).
You can slow down the exhalation specifically by counting, humming or pursing your lips as you breathe out.
In contrast to these calming breathing practices, energising fast-paced breathwork increases arousal. For example, fire breathing (breathe in and out quickly, but not deeply, through your nose in a consistent rhythm) and Lion’s breath (breathe out through your mouth, stick your tongue out and make a strong “haa” sound).
What is happening in the body?
Deep and slow breathing, especially with a long exhale, is the best way to stimulate the vagus nerves. The vagus nerves pass through the diaphragm and are the main nerves of the parasympathetic nervous system.
Simulating the vagus nerves calms our sympathetic nervous system (fight or flight) stress response. This improves mood, lowers the stress hormone cortisol and helps to regulate emotions and responses. It also promotes more coordinated brain activity, improves immune function and reduces inflammation.
Taking deep, diaphragmatic breaths also has physical benefits. This improves blood flow, lung function and exercise performance, increases oxygen in the body, and strengthens the diaphragm.
Slow breathing reduces heart rate and blood pressure and increases heart rate variability (normal variation in time between heart beats). These are linked to better heart health.
Taking shallow, quick, rhythmic breaths in and out through your nose stimulates the sympathetic nervous system. Short-term, controlled activation of the stress response is healthy and develops resilience to stress.
Breathing in through the nose
We are designed to inhale through our nose, not our mouth. Inside our nose are lots of blood vessels, mucous glands and tiny hairs called cilia. These warm and humidify the air we breathe and filter out germs and toxins.
We want the air that reaches our airways and lungs to be clean and moist. Cold and dry air is irritating to our nose and throat, and we don’t want germs to get into the body.
Nasal breathing increases parasympathetic activity and releases nitric oxide, which improves airway dilation and lowers blood pressure.
Consistently breathing through our mouth is not healthy. It can lead to pollutants and infections reaching the lungs, snoring, sleep apnoea, and dental issues including cavities and jaw joint problems.
Breathing can be high and shallow when we are stressed. mi_viri/Shutterstock A free workout
Slow breathing – even short sessions at home – can reduce stress, anxiety and depression in the general population and among those with clinical depression or anxiety. Research on breathwork in helping post-traumatic stress disorder (PTSD) is also promising.
Diaphragmatic breathing to improve lung function and strengthen the diaphragm can improve breathing and exercise intolerance in chronic heart failure, chronic obstructive pulmonary disease and asthma. It can also improve exercise performance and reduce oxidative stress (an imbalance of more free radicals and/or less antioxidants, which can damage cells) after exercise.
Waiting at the lights? This could be your signal to do some breathwork. doublelee/Shutterstock A mind-body connection you can access any time
If you feel stressed or anxious, you might subconsciously take shallow, quick breaths, but this can make you feel more anxious. Deep diaphragmatic breaths through your nose and focusing on strong exhalations can help break this cycle and bring calm and mental clarity.
Just a few minutes a day of breathwork can improve your physical and mental health and wellbeing. Daily deep breathing exercises in the workplace reduce blood pressure and stress, which is important since burnout rates are high.
Bottom line: any conscious control of your breath throughout the day is positive.
So, next time you are waiting in a line, at traffic lights or for the kettle to boil, take a moment to focus on your breath. Breathe deeply into your belly through your nose, exhale slowly, and enjoy the benefits.

How To Regrow Receding Gums
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
One of the problems with the human form is that our teeth evolved to last us for the whole of our life, with plenty of room to spare before our eventual death at the ripe old age of about 35 on average. Dr. Ellie Phillips advises those of us who might be a bit older than that, on how we can avoid becoming “too long in the tooth”—in other words, how to keep our gums, and thus our teeth, in place and healthy.
Getting to the root of the problem
The single biggest cause of gum recession is an acidic environment in the mouth, which harms teeth and gums alike. This acidic environment is produced not merely by consuming acid foods or drinks, but also (and much more often, and more problematically) by sugary foods and drinks, which are not necessarily themselves acidic, but they feed bacteria that release acids as a by-product of their metabolism. If we consume an acidic food or drink, it’s there for a moment, but if we then salivate and/or take a drink of water, it’s pretty much gone in a few seconds. But those bacteria when we feed them sugar? They are there to stay unless we do something more about them than just drink some water.
Other contributing factors to gum recession include teeth grinding, and (ironically) certain oral care products, especially many artificial teeth whiteners.
In case you were wondering: no, brushing will not* generally cause or even worsen gum recession, but flossing can exacerbate it if it’s already underway.

What to do about it: Dr. Phillips recommends:
- use a moderately firm toothbrush to massage gums and promote blood flow
- avoid acidic oral products and homemade remedies even if they’re not acidic but can be caustic, such as baking soda
- rebuild your gums’ and teeth’s protective biofilm (yes, there are “good bacteria” that are supposed to be there) with proper brushing

- adjust your diet to avoid acids and (especially) sugars
