You’ve had a cold or the flu and your symptoms have begun to subside. Your nose has stopped dripping, your cough is clearing and your head and muscles no longer ache.

You’re ready to get off the couch. But is it too early to go for a run? Here’s what to consider when getting back to exercising after illness.

Exercise can boost your immune system – but not always

Exercise reduces the chance of getting respiratory infections by increasing your immune function and the ability to fight off viruses.

However, an acute bout of endurance exercise may temporarily increase your susceptibility to upper respiratory infections, such as colds and the flu, via the short-term suppression of your immune system. This is known as the “open window” theory.

A study from 2010 examined changes in trained cyclists’ immune systems up to eight hours after two-hour high-intensity cycling. It found important immune functions were suppressed, resulting in an increased rate of upper respiratory infections after the intense endurance exercise.

So, we have to be more careful after performing harder exercises than normal.

Can you exercise when you’re sick?

This depends on the severity of your symptoms and the intensity of exercise.

Mild to moderate exercise (reducing the intensity and length of workout) may be OK if your symptoms are a runny nose, nasal congestion, sneezing and minor sore throat, without a fever.

Exercise may help you feel better by opening your nasal passages and temporarily relieving nasal congestion.

However, if you try to exercise at your normal intensity when you are sick, you risk injury or more serious illness. So it’s important to listen to your body.

If your symptoms include chest congestion, a cough, upset stomach, fever, fatigue or widespread muscle aches, avoid exercising. Exercising when you have these symptoms may worsen the symptoms and prolong the recovery time.

If you’ve had the flu or another respiratory illness that caused a high fever, make sure your temperature is back to normal before getting back to exercise. Exercising raises your body temperature, so if you already have a fever, your temperature will become high quicker, which makes you sicker.

If you have COVID or other contagious illnesses, stay at home, rest and isolate yourself from others.

When you’re sick and feel weak, don’t force yourself to exercise. Focus instead on getting plenty of rest. This may actually shorten the time it takes to recover and resume your normal workout routine.

I’ve been sick for a few weeks. What has happened to my strength and fitness?

You may think taking two weeks off from training is disastrous, and worry you’ll lose the gains you’ve made in your previous workouts. But it could be just what the body needs.

It’s true that almost all training benefits are reversible to some degree. This means the physical fitness that you have built up over time can be lost without regular exercise.

To study the effects of de-training on our body functions, researchers have undertaken “bed rest” studies, where healthy volunteers spend up to 70 days in bed. They found that V̇O₂max (the maximum amount of oxygen a person can use during maximal exercise, which is a measure of aerobic fitness) declines 0.3–0.4% a day. And the higher pre-bed-rest V̇O₂max levels, the larger the declines.

In terms of skeletal muscles, upper thigh muscles become smaller by 2% after five days of bed rest, 5% at 14 days, and 12% at 35 days of bed rest.

Muscle strength declines more than muscle mass: knee extensor muscle strength gets weaker by 8% at five days, 12% at 14 days and more than 20% after around 35 days of bed rest.

This is why it feels harder to do the same exercises after resting for even five days.

But in bed rest studies, physical activities are strictly limited, and even standing up from a bed is prohibited during the whole length of a study. When we’re sick in bed, we have some physical activities such as sitting on a bed, standing up and walking to the toilet. These activities could reduce the rate of decreases in our physical functions compared with study participants.

How to ease back into exercise

Start with a lower-intensity workout initially, such as going for a walk instead of a run. Your first workout back should be light so you don’t get out of breath. Go low (intensity) and go slow.

Gradually increase the volume and intensity to the previous level. It may take the same number of days or weeks you rested to get back to where you were. If you were absent from an exercise routine for two weeks, for example, it may require two weeks for your fitness to return to the same level.

If you feel exhausted after exercising, take an extra day off before working out again. A day or two off from exercising shouldn’t affect your performance very much.

  • Debate over tongue tie procedures in babies continues. Here’s why it can be beneficial for some infants

    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.

    There is increasing media interest about surgical procedures on new babies for tongue tie. Some hail it as a miracle cure, others view it as barbaric treatment, though adverse outcomes are rare.

    Tongue tie occurs when the tissue under the tongue is attached to the lower gum or floor of the mouth in a way that can restrict the movement or range of the tongue. This can impact early breastfeeding in babies. It affects an estimated 8% of children under one year of age.

    While there has been an increase in tongue tie releases (also called division or frenotomy), it’s important to keep this in perspective relative to the increase in breastfeeding rates.

    The World Health Organization recommends exclusive breastfeeding for the first six months of life, with breastfeeding recommended into the second year of life and beyond for the health of mother and baby as well as optimal growth. Global rates of breastfeeding infants for the first six months have increased from 38% to 48% over the past decade. So, it is not surprising there is also an increase in the number of babies being referred globally with breastfeeding challenges and potential tongue tie.

    An Australian study published in 2023 showed that despite a 25% increase in referrals for tongue tie division between 2014 and 2018, there was no increase in the number of tongue tie divisions performed. Tongue tie surgery rates increased in Australia in the decade from 2006 to 2016 (from 1.22 per 1,000 population to 6.35) for 0 to 4 year olds. There is no data on surgery rates in Australia over the last eight years.

    Tongue tie division isn’t always appropriate but it can make a big difference to the babies who need it. More referrals doesn’t necessarily mean more procedures are performed.

    How tongue tie can affect babies

    When tongue tie (ankyloglossia) restricts the movement of the tongue, it can make it more difficult for a baby to latch onto the mother’s breast and painlessly breastfeed.

    Earlier this month, the International Consortium of oral Ankylofrenula Professionals released a tongue tie position statement and practice guideline. Written by a range of health professionals, the guidelines define tongue tie as a functional diagnosis that can impact breastfeeding, eating, drinking and speech. The guidelines provide health professionals and families with information on the assessment and management of tongue tie.

    Tongue tie release has been shown to improve latch during breastfeeding, reduce nipple pain and improve breast and bottle feeding. Early assessment and treatment are important to help mothers breastfeed for longer and address any potential functional problems.

    Where to get advice

    If feeding isn’t going well, it may cause pain for the mother or there may be signs the baby isn’t attaching properly to the breast or not getting enough milk. Parents can seek skilled help and assessment from a certified lactation consultant or International Board-Certified Lactation Consultant who can be found via online registry.

    Alternatively, a health professional with training and skills in tongue tie assessment and division can assist families. This may include a doctor, midwife, speech pathologist or dentist with extended skills, training and experience in treating babies with tongue tie.

    When access to advice or treatment is delayed, it can lead to unnecessary supplementation with bottle feeds, early weaning from breastfeeding and increased parental anxiety.

    Getting a tongue tie assessment

    During assessment, a qualified health professional will collect a thorough case history, including pregnancy and birth details, do a structural and functional assessment, and conduct a comprehensive breastfeeding or feeding assessment.

    They will view and thoroughly examine the mouth, including the tongue’s movement and lift. The appearance of where the tissue attaches to the underside of the tongue, the ability of the tongue to move and how the baby can suck also needs to be properly assessed.

    Treatment decisions should focus on the concerns of the mother and baby and the impact of current feeding issues. Tongue tie division as a baby is not recommended for the sole purpose of avoiding speech problems in later life if there are no feeding concerns for the baby.

    Treatment options

    The Australian Dental Association’s 2020 guidelines provide a management pathway for babies diagnosed with tongue tie.

    Once feeding issues are identified and if a tongue tie is diagnosed, non-surgical management to optimise positioning, latch and education for parents should be the first-line approach.

    If feeding issues persist during follow-up assessment after non-surgical management, a tongue tie division may be considered. Tongue tie release may be one option to address functional challenges associated with breastfeeding problems in babies.

    There are risks associated with any procedure, including tongue tie release, such as bleeding. These risks should be discussed with the treating practitioner before conducting any laser, scissor or scalpel tongue tie procedure.

    Post-release support by a certified lactation consultant or feeding specialist is necessary after a tongue tie division. A post-release treatment plan should be developed by a team of health professionals including advice and support for breastfeeding to address both the mother and baby’s individual needs.

  • The Twenty-Four Hour Mind – by Dr. Rosalind Cartwright

    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.

    We’ve reviewed books about sleep before, and even about dreaming, so what does this one have to offer that’s new?

    Quite a lot, actually! Before Dr. Cartwright, there were mainly two models of sleep and dreaming:

    • The “top-down” model of psychoanalysts: our minds shape our dreams which in turn reveal things about us as people
    • The “bottom-up” model of neuroscientists: our brains need to go through regular maintaince cycles, of which vivid hallucinations are a quirky side-effect.

    And now, as Dr. Cartwright puts it:

    ❝I will lay out a new [horizontal] psychological model of the twenty-four hour mind; that is, how the predominantly conscious (waking) and unconscious (sleeping) forms of mental behavior interact through the brain’s regular, but differently organized, states of waking, sleeping, and dreaming.❞

    This she does in the exploratory style of a 224-page lecture, which sounds like it might be tedious, but is actually attention-grabbing and engaging throughout. This book is more of a page-turner than soporific bedtime reading!

    Bottom line: if you’d like to know more about the effect your waking and sleeping brain have on each other (to include getting in between those and making adjutments as appropriate), this is very much an elucidating read!

  • Tasty Versatile Rice

    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.

    In the nearish future, we’re going to do some incredible rice dishes, but first we need to make sure we’re all on the same page about cooking rice, so here’s a simple recipe first, to get technique down and work in some essentials. We’ll be using wholegrain basmati rice, because it has a low glycemic index, lowest likelihood of heavy metal contamination (a problem for some kinds of rice), and it’s one of the easiest rices to cook well.

    You will need

    • 1 cup wholegrain basmati rice (it may also be called “brown basmati rice“; this is the same)
    • 1 1/2 cups vegetable stock (ideally you have made this yourself from vegetable offcuts that you saved in the freezer, then it will be healthiest and lowest in sodium; failing that, low-sodium vegetable stock cubes can be purchased at most large supermarkets. and then made up at home with hot water)
    • 1 tbsp extra virgin olive oil
    • 1 tbsp chia seeds
    • 1 tbsp black pepper, coarse ground
    • 1 tsp turmeric powder (this small quantity will not change the flavor, but it has important health benefits, and also makes the rice a pleasant golden color)
    • 1 tsp garlic powder
    • 1 tsp yeast extract (this gently improves the savory flavor and also adds vitamin B12)
    • Optional small quantity of green herbs for garnish. Cilantro is good (unless you have the soap gene); parsley never fails.

    This is the ingredients list for a super-basic rice that will go with anything rice will go with; another day we can talk more extensive mixes of herbs and spice blends for different kinds of dishes (and different health benefits!), but for now, let’s get going!

    Method

    (we suggest you read everything at least once before doing anything)

    1) Wash the rice thoroughly. We recommend using a made-for-purpose rice-washing bowl (like this one, for example), but failing that, simply rinse it thoroughly with cold water using a bowl and a sieve. You will probably need to rinse it 4–5 times, but with practice, it will only take a few seconds per rinse, and the water will be coming up clear.

    2) Warm the pan. It doesn’t matter for the moment whether you’re using an electronic rice cooker, a stovetop pressure cooker, electronic pressure cooker, or just a sturdy pan with a heavy lid available, aside from that if it’s something non-stovetop, you now want it to be on low to warm up already.

    3) Separately in a saucepan, bring your stock to a simmer

    4) Put the tbsp of olive oil into the pan (even if you’re confident the rice won’t stick; this isn’t entirely about that) and turn up the heat (if it’s a very simple rice cooker, most at least have a warm/cook differentiation; if so, turn it to “cook”). You don’t want the oil to get to the point of smoking, so, to test the temperature as it heats, flick a single drop of water from your fingertip (you did wash your hands first, right? We haven’t been including that step, but please do wash your hands before doing kitchen things) into the pan. If it sizzles, the pan is hot enough now for the next step.

    5) Put the rice into the pan. That’s right, with no extra liquid yet; we’re going to toast it for a moment. Stir it a little, for no more than a minute; keep it moving; don’t let it burn! If you try this several times and fail, it could be that you need a better pan. Treat yourself to one when you get the opportunity; until then, skip the toasting part if necessary.

    6) Add the chia seeds and spices, followed by the stock, followed by the yeast extract. Why did we do the stock before the yeast extract? It’s because hot liquid will get all the yeast extract off the teaspoon 🙂

    7) Put the lid on/down (per what kind of pan or rice cooker you are using), and turn up the heat (if it is a variable heat source) until a tiny bit of steam starts making its way out. When it does, turn it down to a simmer, and let the rice cook. Don’t stir it, don’t jiggle it; trust the process. If you stir or jiggle it, the rice will cook unevenly and, paradoxically, probably stick.

    8) Do keep an eye on it, because when steam stops coming out, it is done, and needs taking off the heat immediately. If using an automatic rice cooker, you can be less attentive if you like, because it will monitor this for you.

    Note: if you are using a simple pan with a non-fastening lid (any other kind of rice cooking setup is better), more steam will escape than the other methods, and it’s possible that it might run out of steam (literally) before the rice is finished. If the steam stops and you find the rice isn’t done, add a splash of water as necessary (the rice doesn’t need to be submerged, it just needs to have liquid; the steam is part of the cooking process), and make a note of how much you had to add (so that next time you can just add it at the start), and put it back on the heat until it is done.

    9) Having taken it off the heat, let it sit for 5 minutes (with the lid still on) before doing any fluffing-up. Then you can fluff-up and serve, adding the garnish if you want one.

    Enjoy!

  • Paulina Porizkova (Former Supermodel) Talks Menopause, Aging, & Appearances

    Are supermodels destined to all eventually become “Grizabella the Glamor Cat”, a washed-up shell of their former glory? Is it true that “men grow cold as girls grow old, and we all lose our charms in the end”? And what—if anything—can we do about it?

    Insights from a retired professional

    Paulina Porizkova is 56, and she looks like she’s… 56, maybe? Perhaps a little younger or a bit older depending on the camera and lighting and such.

    It’s usually the case, on glossy magazine covers and YouTube thumbnails, that there’s a 20-year difference between appearance and reality, but not here. Why’s that?

    Porizkova noted that many celebrities of a similar age look younger, and felt bad. But then she noted that they’d all had various cosmetic work done, and looked for images of “real” women in their mid-50s, and didn’t find them.

    Note: we at 10almonds do disagree with one thing here: we say that someone who has had cosmetic work done is no less real for it; it’s a simple matter of personal choice and bodily autonomy. She is, in our opinion, making the same mistake as people make when they say such things as “real people, rather than models”, as though models are not also real people.

    Porizkova found modelling highly lucrative but dehumanizing, and did not enjoy the objectification involved—and she enjoyed even less, when she reached a certain age, negative comments about aging, and people being visibly wrong-footed when meeting her, as they had misconceptions based on past images.

    As a child and younger adult through her modelling career, she felt very much “seen and not heard”, and these days, she realizes she’s more interesting now but feels less seen. Menopause coincided with her marriage ending, and she felt unattractive and ignored by her husband; she questioned her self-worth, and felt very bad about it. Then her husband (they had separated, but had not divorced) died, and she felt even more isolated—but it heightened her sensitivity to life.

    In her pain and longing for recognition, she reached out through her Instagram, crying, and received positive feedback—but still she struggles with expressing needs and feeling worthy.

    And yet, when it comes to looks, she embraces her wrinkles as a form of expression, and values her natural appearance over cosmetic alterations.

    She describes herself as a work in progress—still broken, still needing cleansing and healing, but proud of how far she’s come so far, and optimistic with regard to the future.

  • Healthiest-Three-Nut Butter

    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.

    We’re often telling you to “diversify your nuts”, so here’s a great way to get in three at once with no added sugar, palm oil, or preservatives, and only the salt you choose to put in. We’ve picked three of the healthiest nuts around, but if you happen to be allergic, don’t worry, we’ve got you covered too.

    You will need

    • 1 cup almonds (if allergic, substitute a seed, e.g. chia, and make it ½ cup)
    • 1 cup walnuts (if allergic, substitute a seed, e.g. pumpkin, and make it ½ cup)
    • 1 cup pistachios (if allergic, substitute a seed, e.g. poppy, and make it ½ cup)
    • 1 tbsp almond oil (if allergic, substitute extra virgin olive oil) (if you prefer sweet nut butter, substitute 1 tbsp maple syrup; the role here is to emulsify the nuts, and this will do the same job)
    • Optional: ¼ tsp MSG or ½ tsp low-sodium salt

    Method

    (we suggest you read everything at least once before doing anything)

    1a) If using nuts, heat your oven to 350℉ / 180℃. Place the nuts on a baking tray lined with baking paper, and bake/roast for about 10 minutes, but keep an eye on it to ensure the nuts don’t burn, and jiggle them if necessary to ensure they toast evenly. Once done, allow to cool.

    1b) If using seeds, you can either omit that step, or do the same for 5 minutes if you want to, but really it’s not necessary.

    2) Blend all ingredients (nuts/seeds, oil, MSG/salt) in a high-speed blender. Note: this will take about 10 minutes in total, and we recommend you do it in 30-second bursts so as to not overheat the motor. You also may need to periodically scrape the mixture down the side of the blender, to ensure a smooth consistency.

    3) Transfer to a clean jar, and enjoy at your leisure:

    It’s Q&A Day at 10almonds!

    Q: I would be interested in learning more about collagen and especially collagen supplements/powders and of course if needed, what is the best collagen product to take. What is collagen? Why do we need to supplement the collagen in our body? Thank you PS love the information I am receiving in the news letters. Keep it up

    We’re glad you’re enjoying them! Your request prompted us to do our recent Research Review Monday main feature on collagen supplementation—we hope it helped, and if you’ve any more specific (or other) question, go ahead and let us know! We love questions and requests

    Q: Great article about the health risks of salt to organs other than the heart! Is pink Himalayan sea salt, the pink kind, healthier?

    Thank you! And, no, sorry. Any salt that is sodium chloride has the exact same effect because it’s chemically the same substance, even if impurities (however pretty) make it look different.

    If you want a lower-sodium salt, we recommend the kind that says “low sodium” or “reduced sodium” or similar. Check the ingredients, it’ll probably be sodium chloride cut with potassium chloride. Potassium chloride is not only not a source of sodium, but also, it’s a source of potassium, which (unlike sodium) most of us could stand to get a little more of.

    For your convenience: here’s an example on Amazon!

    Bonus: you can get a reduced sodium version of pink Himalayan salt too!

    Q: Can you let us know about more studies that have been done on statins? Are they really worth taking?

    That is a great question! We imagine it might have been our recent book recommendation that prompted it? It’s quite a broad question though, so we’ll do that as a main feature in the near future!

    Q: Is MSG healthier than salt in terms of sodium content or is it the same or worse?

    Great question, and for that matter, MSG itself is a great topic for another day. But your actual question, we can readily answer here and now:

    • Firstly, by “salt” we’re assuming from context that you mean sodium chloride.
    • Both salt and MSG do contain sodium. However…
    • MSG contains only about a third of the sodium that salt does, gram-for-gram.
    • It’s still wise to be mindful of it, though. Same with sodium in other ingredients!
    • Baking soda contains about twice as much sodium, gram for gram, as MSG.

    Wondering why this happens?

    Salt (sodium chloride, NaCl) is equal parts sodium and chlorine, by atom count, but sodium’s atomic mass is lower than chlorine’s, so 100g of salt contains only 39.34g of sodium.

    Baking soda (sodium bicarbonate, NaHCO₃) is one part sodium for one part hydrogen, one part carbon, and three parts oxygen. Taking each of their diverse atomic masses into account, we see that 100g of baking soda contains 27.4g sodium.

    MSG (monosodium glutamate, C₅H₈NO₄Na) is only one part sodium for 5 parts carbon, 8 parts hydrogen, 1 part nitrogen, and 4 parts oxygen… And all those other atoms put together weigh a lot (comparatively), so 100g of MSG contains only 12.28g sodium.

    Q: Thanks for the info about dairy. As a vegan, I look forward to a future comment about milk alternatives

    Thanks for bringing it up! What we research and write about is heavily driven by subscriber feedback, so notes like this really help us know there’s an audience for a given topic!

    We’ll do a main feature on it, to do it justice. Watch out for Research Review Monday!
