Why might someone not want to do mobility training? Here are some important reasons:
Make an informed choice
Here’s Liv’s hit-list of reasons to skip mobility training:
- Poor Circulation: Avoid mobility training if you don’t want to improve or maintain good blood circulation, which aids muscle recovery and reduces soreness.
- Low Energy Levels: Mobility training increases oxygen flow to the brain and muscles, boosting energy. Skip it if you prefer feeling sluggish!
- Digestive Health: Stretches that rotate the torso aid digestion and relieve bloating. Definitely best to avoid it if you’re uninterested in improving digestive health.
- Joint Health: Mobility work stimulates synovial fluid production, reducing joint friction and promoting longevity. You can skip it if you don’t care about comfortable movement.
- Sleep Quality: Gentle stretching triggers relaxation, aiding restful sleep. Avoid it if you enjoy restless nights!
- Pain Tolerance: Stretching trains the nervous system to handle discomfort better. Skip it if you prefer suffering 🙂
- Headache Reduction: Mobility work relieves tension in the neck and shoulders, reducing the occurrence and severity of headaches. No need to do it if you’re fine with frequent headaches.
- Immune System Support: Mobility training boosts lymphatic circulation, aiding the immune system. Avoid it if you prefer your immune system to get exciting in a bad way.
- Stress Reduction: Mobility exercises release endorphins and lower cortisol levels, reducing stress. So, it is certainly best to skip it if you prefer feeling stressed and enjoy the many harmful symptoms of high cortisol levels!

To Pee Or Not To Pee
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.
Is it “strengthening” to hold, or are we doing ourselves harm if we do? Dr. Heba Shaheed explains in this short video:
A flood of reasons not to hold
Humans should urinate 4–6 times daily, but for many people, the demands of modern life often lead to delaying urination, raising questions about its effects on the body.
So first, let’s look at how it all works: the bladder is part of the urinary system, which includes the kidneys, ureters, urethra, and sphincters. Urine is produced by the kidneys and transported via the ureters into the bladder, a hollow organ with a muscular wall. This muscle (called the detrusor) allows the bladder to inflate as it fills with urine (bearing in mind, the main job of any muscle is to be able to stretch and contract).
As the bladder fills, stretch receptors in that muscle signal fullness to the spinal cord. This triggers the micturition reflex, causing the detrusor to contract and the internal urethral sphincter to open involuntarily. Voluntary control over the external urethral sphincter allows a person to delay or release urine as needed.
So, at what point is it best to go forth and pee?
For most people, bladder fullness is first noticeable at around 150-200ml, with discomfort occurring at 400-500ml (that’s about two cups*). Although the bladder can stretch to hold up to a liter, exceeding this capacity can cause it to rupture, a rare but serious condition requiring surgical intervention.
*note, however, that this doesn’t necessarily mean that drinking two cups will result in two cups being in your bladder; that’s not how hydration works. Unless you are already perfectly hydrated, most if not all of the water will be absorbed into the rest of your body where it is needed. Your bladder gets filled when your body has waste products to dispose of that way, and/or is overhydrated (though overhydration is not very common).
Habitually holding urine and/or urinating too quickly (note: not “too soon”, but literally, “too quickly”, we’re talking about the velocity at which it exits the body) can weaken pelvic floor muscles over time. This can lead to bladder pain, urgency, incontinence, and/or a damaged pelvic floor.
In short: while the body’s systems are equipped to handle occasional delays, holding it regularly is not advisable. For the good of your long-term urinary health, it’s best to avoid straining the system and go whenever you feel the urge.

You May Have More Air Pollution In Your Home Than In The Street
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.
Certainly, gas stoves and heaters can cause indoor air pollution, with carbon monoxide (CO) being the main risk. Even if you have a CO alarm, the level at which it will go off is usually the “this will kill you tonight if you don’t do something about it soon” level, rather than the “this will slowly kill your brain cells but you’ll keep functioning otherwise, until one day you don’t” levels of CO.
Still, do by all means have a CO alarm if you have anything in your house that can release CO!
Fun fact about those stoves:
❝Just 1 kilogram of cooking fuel emits 10 quadrillion particles smaller than 3 nanometers, which matches or exceeds what’s emitted from cars with internal combustion engines.
At that rate, you might be inhaling 10-100 times more of these sub-3 nanometer particles from cooking on a gas stove indoors than you would from car exhaust while standing on a busy street.❞
But today, we’re not here about that
Rather, we are looking at some more innocent-seeming things, such as scented cleaning products and air fresheners. Notably, the biggest problem is often not even the cleaning chemicals themselves. Of course: please don’t breathe bleach fumes, etc.
But that’s an obvious risk, and today we’re about the less obvious risks.
So… What is the less obvious risk here?
It’s the fragrances. The terpenes used to hold them react with ozone in the air, to create new nanoparticles. And, just like the nanoparticles from the stove, these can reach very high concentrations indoors, and suffice it to say, if you can smell the fragrance then you have the pollutants inside you.
You can read about how badly different products score, here:
Rapid Nucleation and Growth of Indoor Atmospheric Nanocluster Aerosol during the Use of Scented Volatile Chemical Products in Residential Buildings ← you’ll need to scroll down to the table with different cleaning products and air fresheners
Further, the seemingly-harmless scented candle is, as it turns out, quite a menace too:
❝Full-scale emission experiments were conducted in the Purdue zEDGE Test House using a variety of scented candles (n = 5) and wax warmers/melts (n = 14) under different outdoor air exchange rates (AERs). Terpene concentrations were measured in real-time using a proton transfer reaction time-of-flight mass spectrometer (PTR-TOF-MS). PTR-TOF-MS measurements revealed that scented candle and wax warmer/melt products emit a variety of monoterpenes (C10H16) and oxygen-containing monoterpenoids (C10H14O, C10H16O, C10H18O, C10H20O), with peak concentrations in the range of 10−1 to 102 ppb. Monoterpene EFs were much greater for scented wax warmers/melts (C10H16 EFs ∼ 102 mg per g wax consumed) compared to scented candles (C10H16 EFs ∼ 10−1 to 100 mg per g wax consumed). Significant emissions of reactive terpenes from both products, along with nitrogen oxides (NO, NO2) from candles, depleted indoor ozone (O3) concentrations. Terpene iFs were similar between the two products (iFs ∼ 103 ppm) and increased with decreasing outdoor AER. Terpene iFs during concentration decay periods were similar to, or greater than, iFs during active emission periods for outdoor AERs ≤ 3.0 h−1.
Overall, scented wax warmers/melts were found to release greater quantities of monoterpenes compared to other fragranced consumer products used in the home, including botanical disinfectants, hair care products, air fresheners, and scented sprays.❞
Put in fewer words: scented candles are bad, and wax melts (the kind with no flame, that one might easily expect to thus produce fewer emissions) are at least as bad if not worse, and both are even worse than cleaning products.
Some of the same research team conducted further studies, because of this this, finding:
❝We performed field measurements in a residential test house to investigate atmospheric nanoparticle formation from scented wax melt use. We employed a high-resolution particle size magnifier-scanning mobility particle sizer (PSMPS) and a proton transfer reaction time-of-flight mass spectrometer (PTR-TOF-MS) for real-time monitoring of indoor atmospheric nanoparticle size distributions and terpene mixing ratios, respectively.
Our findings reveal that terpenes released from scented wax melts react with indoor atmospheric ozone (O3) to initiate new particle formation (NPF) events, resulting in significant indoor atmospheric nanoparticle concentrations (>106 cm–3) comparable to those emitted by combustion-based scented candles, gas stoves, diesel engines, and natural gas engines.
We show that scented wax melt-initiated NPF events can result in significant respiratory exposures, with nanoparticle respiratory tract deposited dose rates similar to those determined for combustion-based sources.
Our results challenge the perception of scented wax melts as a safer alternative to combustion-based aromatherapy❞

The surprising ways ‘swimming off’ a hangover can be risky, even if alcohol has left your system
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.
It’s the morning after a big night and you’re feeling the effects of too much alcohol.
So it can be tempting to “refresh” and take the edge off a hangover with a swim at the beach, or a dip in the cool waters of your local river or pool.
But you might want to think twice.
The day after heavy drinking can affect your body, energy levels and perception of risk in many ways. This means you’re more likely to drown or make careless decisions – even without high levels of alcohol in your blood.
Wanderlust Media/Shutterstock Alcohol + water + summer = drowning
Alcohol is one of the main reasons why someone’s more likely to die due to drowning. And Australians consume a lot of it, including around the water.
The risk of drowning, and injury, including incidents involving alcohol, dramatically increases over the summer festive period – in particular on public holidays and long weekends.
Among people aged 18 and over who drowned in rivers where alcohol was involved, we found some 40% had a blood alcohol concentration of at least 0.20%. That’s four times the upper legal limit of 0.05% when driving a car on a full licence.
When we breathalysed people at four Australian rivers, we found higher levels of blood alcohol with higher temperatures, and particularly on public holidays.
At the beach, intoxication due to alcohol and/or drugs is involved in 23% of drowning deaths with an average blood alcohol concentration of 0.19%.
How about if you’re hungover?
Getting alcohol out of your body is a relatively slow process. On average, alcohol is metabolised at a rate of 0.015% per hour. So if someone stops drinking at 2am with a blood alcohol concentration of 0.20%, their alcohol levels don’t drop to zero until 4pm the next day.
Although hangovers can vary from person to person, typical symptoms include headache, muscle aches, fatigue, weakness, thirst, nausea, stomach pain, vertigo, irritability, sensitivity to light and sound, anxiety, sweating and increased blood pressure.
As well as feeling a bit dusty, the day after an evening of heavy drinking, you’re not so good at identifying risks and reacting to them.
In a pool, this might mean not noticing it’s too shallow to dive safely. In natural waterways, this might mean not noticing a strong river current or a rip current at the beach. Or someone might notice these hazards but swim or dive in anyway.
You don’t have to have alcohol in your blood to be affected. Fatigue can set in, leading you to make careless decisions. tismaja/Shutterstock In one study, we found that after a four-day Australian music festival where people drank heavily, even people who were sober (no longer had alcohol in their blood) were still affected.
Compared to baseline tests in the lab we ran three weeks before the festival, people who were sober the day after the festival had faster reaction times in a test to gauge their attention. But they made more mistakes. This suggests hangovers coupled with fatigue lead to quicker but more careless behaviour.
In and around water this could be the difference between life and death.
Positive blood alcohol readings, including of alcohol from the night before, are commonly implicated in drowning deaths as a result of risky behaviours such as jumping into the water, both at a river and along the coast. Jumping can cause physical injury or render you unconscious, leading to drowning.
Alcohol, including the day after drinking, can also make drowning more likely for a number of other reasons. It also reduces people’s coordination and reaction times.
What else is going on?
Alcohol makes the blood vessels near your skin open up (dilate). So more blood flows into them, making you feel hot. This means you may stay in colder water for longer, increasing your risk of hypothermia.
Alcohol can even make CPR (cardiopulmonary resuscitation) less effective, should you need to be resuscitated.
Normally, your body controls levels of certain minerals (or electrolytes) in the blood. But electrolyte imbalance is common after heavy drinking, including the day after. It’s the reason why hangover symptoms such as muscle pain can lead to cramps in your arms or legs. This can become dangerous when being in or on the water.
Low blood sugar levels the day after drinking is also common. This can lead to people becoming exhausted more quickly when doing physical activities, including swimming.
Other hazards include cold water, high waves and deep water, all of which your body may not be capable of dealing with if you’re feeling the effects of a big night.
What can we do about it?
Authorities regularly warn about the dangers of alcohol intoxication and being near the water. Young people and men are often targeted because these are the groups more likely to drown where alcohol is involved.
Beaches may have alcohol-free zones. Rivers rarely have the same rules, despite similar dangers. https://www.youtube.com/embed/5Salt-kkGUo?wmode=transparent&start=0 Royal Life Saving urges men to ‘make the right call’ and avoid alcohol around the water.
How to stay safe around water if you’re drinking
So take care this summer and stay out of the water if you’re not feeling your best:
- do your swimming before your drinking
- look out for your mates, especially ones who may have had a few too many or are hungover
- avoid getting back into the water after you’ve drunk alcohol or if you’re not feeling your best the next day.

Wondering how to spot the signs of postpartum depression?
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.
Postpartum depression, or PPD, is a debilitating, potentially life-threatening mental health condition that impacts about one in eight people who give birth in the U.S. While it’s normal to feel worried or stressed after becoming a parent, PPD can cause feelings of extreme sadness or anxiety that may lead to suicidal thoughts.
Read on to learn what PPD is, what causes it, how it’s treated, and more.
What is the difference between the baby blues and postpartum depression?
Postpartum blues, or the “baby blues,” impact up to 80 percent of new parents. The baby blues may cause bouts of crying, mood swings, anxiety, sadness, reduced concentration, irritability, changes in appetite, and trouble sleeping, but symptoms are fleeting.
“Baby blues are a transient period—hours to a few days—of emotionality that does not impair one’s functioning or cause severe symptoms like suicidality,” says Dr. Jennifer L. Payne, a professor of psychiatry and neurobehavioral sciences at the University of Virginia. “[Postpartum depression] can cause severe symptoms, including suicidality.”
In addition to causing more debilitating symptoms, PPD can last for months.
Some new parents also experience postpartum psychosis, which can cause hallucinations and delusions. However, unlike PPD, postpartum psychosis is rare.
What are the symptoms of postpartum depression?
PPD symptoms may include:
- Feeling depressed, irritable, angry, or hopeless
- Severe mood swings
- Difficulty bonding with your baby
- Withdrawing from family and friends
- Changes in appetite or sleeping patterns
- Extreme fatigue
- Difficulty concentrating
- Anxiety and panic attacks
- Thoughts of harming yourself or your baby
- Thoughts of death or suicide
If you are experiencing symptoms of PPD, Payne recommends seeking help from a primary care provider or obstetrician right away.
“It’s really important—not just for you, but for your baby,” Payne explains. “Babies exposed to significant PPD have slower language development, lower IQs, and more behavioral problems.”
Your health care provider will ask you a series of screening questions to determine if you are experiencing PPD.
What causes postpartum depression?
Research suggests that the drop in hormones that occurs after birth, genetics, and sleep deprivation may contribute to PPD.
You may be at higher risk of developing PPD if you have a history of mental health conditions like depression or bipolar disorder, have relatives who’ve experienced PPD, or experienced stressful events during or after pregnancy.
How is postpartum depression treated?
“PPD is usually treated with antidepressant medications—typically SSRIs and now with the new FDA-approved medication, zuranolone,” says Payne. Therapy has also been shown to help people manage PPD.
Your health care provider can help determine the best treatment options for you and can outline the risks and benefits of taking certain medications while breastfeeding.
For referrals to care, information about local support groups, and other mental health resources for new parents, call the National Maternal Mental Health Hotline or Postpartum Support International. If you are experiencing a mental health emergency, call or text the 988 Suicide & Crisis Lifeline.
Can non-birthing parents have postpartum depression?
New parents who did not give birth, including cisgender men, may experience anxiety, depression, irritability, fatigue, and changes in appetite or sleeping patterns after a partner gives birth.
“Everyone knows that mothers’ hormones change a lot during and after pregnancy,” psychologist Scott Bea said in a 2019 Cleveland Clinic article. “But there’s evidence that fathers also experience real changes in their hormone levels after a baby is born.”
Adoptive parents may also show similar symptoms.
If you or anyone you know is considering suicide or self-harm or is anxious, depressed, upset, or needs to talk, call the Suicide & Crisis Lifeline at 988 or text the Crisis Text Line at 741-741. For international resources, here is a good place to begin.

Cashew & Chickpea Balti
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.
When it comes to curries, the humble balti is perhaps the best when you don’t have all day to let something simmer. Filled with healthful spices, this one also comes complete with lots of fiber as well as healthy proteins and fats, with most of its calories coming from the nuts themselves, and the haricot paste base makes for a deliciously creamy curry without having to add anything unhealthy.
You will need
- 1 cup cashews, soaked in warm water for at least 5 minutes, and drained (if allergic, omit)
- 1 can chickpeas (keep the water)
- 1 can haricot beans (keep the water)
- 1 can crushed tomatoes
- 2 medium (or 3 small) red onions, sliced
- red or green chilis, quantity per your preference re heat, chopped
- ½ bulb garlic, crushed
- ½ oz fresh ginger, peeled and finely chopped
- 1 tbsp tomato paste
- 1 tbsp garam masala
- 1 tbsp ground coriander
- 1 tbsp black pepper, coarse ground
- 2 tsp turmeric
- 1 tsp mustard seeds (if allergic, omit)
- 1 tsp sweet cinnamon
- 1 tsp coriander seeds
- ½ tsp MSG or 1 tsp low-sodium salt
- Avocado oil, for frying (extra virgin olive-oil, or cold-pressed coconut oil, are fine alternatives)
- Garnish: handful fresh cilantro, chopped (or parsley, if you have the “cilantro tastes like soap” gene)
Method
(we suggest you read everything at least once before doing anything)
1) Heat a little oil in a large sauté pan (we’re going to need space to work; a large wok is traditional but a sauté pan is convenient), and add the garlic, ginger, mustard seeds, and coriander seeds, stirring for about 2 minutes, then add the onions and chilis, stirring for another 3 minutes. The onions and chilis won’t be fully cooked yet, but that’s fine, we just needed to get them started.
2) Add the crushed tomatoes, stirring them in, and when they get to temperature, turn the heat down to a simmer.
3) Add the chickpeas to the pan, but separately put the chickpea water into a high-speed blender.
4) Add the haricot beans, including the water they came in, to the high-speed blender, as well as the tomato paste and the remaining spices (including the MSG or salt), and blend on high until smooth. Add the curry paste (that’s what you’ve just made in the blender) to the pan, and stir in well.
5) Add the cashews, stirring in well. Taste, and adjust any spices if necessary for your liking. If the onions still aren’t fully cooked, let them simmer until they are, but it shouldn’t take long.
10almonds tip: if perchance you made it too spicy, you can add a little lime juice and the acidity will counteract the heat. Adding lemon juice, lime juice, or some kind of vinegar (depending on what works with the flavor profile of your recipe) is a good last resort to have up your sleeve for fixing a dish that got too spicy.
6) Add the garnish, and serve—we recommend serving it with our Tasty Versatile Rice, but any carb is fine.
Enjoy!

Can You Reverse Gray Hair? A Dermatologist Explains
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.
Betteridge’s Law of Headlines states “any headline that ends in a question mark can be answered by the word no“—it’s not really a universal truth, but it’s true surprisingly often, and, as board certified dermatologist “The Beauty MD” Dr. Sam Ellis explains, it’s true in this case.
But, all is not lost.
Physiological Factors
Hair color is initially determined by genes and gene expression, instructing the body to color it with melanin (brown and black) and/or pheomelanin (blonde and red). If and when the body produces less of those pigments, our hair will go gray.
Factors that affect if/when our hair will go gray include:
- Genetics: primary determinant, essentially a programmed change
- Age: related to the above, but critically, the probability of going gray in any given year increases with age
- Ethnicity: the level of melanin in our skin is an indicator of how long we are likely to maintain melanin in our hair. Black people with the darkest skintones will thus generally go gray last, whereas white people with the lightest skintones will generally go gray first, and so on for a spectrum between the two.
- Medical conditions: immune conditions such as vitiligo, thyroid disease, and pernicious anemia promote an earlier loss of pigmentation
- Stress: oxidative stress, mainly, so factors like smoking will cause earlier graying. But yes, also chronic emotional stress does lead to oxidative stress too. Interestingly, this seems to be more about norepinephrine than cortisol, though.
- Nutrient deficiencies: the body can make a lot of things, but it needs the raw ingredients. Not having the right amounts of important vitamins and minerals will result in a loss of pigmentation (amongst other more serious problems). Vitamins B6, B9, and B12 are talked about in the video, as are iron and zinc. Copper is also needed for some hair colors. Selenium is needed for good hair health in general (but not too much, as an excess of selenium paradoxically causes hair loss), and many related things will stop working properly without adequate magnesium. Hair health will also benefit a lot from plenty of vitamin B7.
So, managing the above factors (where possible; obviously some of the above aren’t things we can influence) will result in maintaining one’s hair pigment for longer. As for texture, by the way, the reason gray hair tends to have a rougher texture is not for the lack of pigment itself, but is due to decreased sebum production. Judicious use of exogenous hair oils (e.g. argan oil, coconut oil, or whatever your preference may be) is a fine way to keep your grays conditioned.
However, once your hair has gone gray, there is no definitive treatment with good evidence for reversing that, at present. Dye it if you want to, or don’t. Many people (including this writer, who has just a couple of streaks of gray herself) find gray hair gives a distinguished look, and such harmless signs of age are a privilege not everyone gets to reach, and thus may be reasonably considered a cause for celebration
