Ice Baths: To Dip Or Not To Dip?

We asked you for your (health-related) view of ice baths, and got the above-depicted, below-described, set of responses:
- About 31% said “ice baths are great for the health; we should take them”
- About 29% said “ice baths’ risks outweigh their few benefits”
- About 26% said “ice baths’ benefits outweigh their few risks”
- About 14% said “ice baths are dangerous and can kill you; best avoided”
So what does the science say?
Freezing water is very dangerous: True or False?
True! Water close to freezing point is indeed very dangerous, and can most certainly kill you.
Fun fact, though: many such people are still saveable with timely medical intervention, in part because the same hypothermia that is killing them also slows down the process* of death
Source (and science) for both parts of that:
Cold water immersion: sudden death and prolonged survival
*and biologically speaking, death is a process, not an event, by the way. But we don’t have room for that today!
(unless you die in some sudden violent way, such as a powerful explosion that destroys your brain instantly; then it’s an event)
Ice baths are thus also very dangerous: True or False?
False! Assuming that they are undertaken responsibly and you have no chronic diseases that make it more dangerous for you.
What does “undertaken responsibly” mean?
Firstly, the temperature should not be near freezing. It should be 10–15℃, which for Americans is 50–59℉.
You can get a bath thermometer to check this, by the way. Here’s an example product on Amazon.
Secondly, your ice bath should last no more than 10–15 minutes. This is not a place to go to sleep.
What chronic diseases would make it dangerous?
Do check with your doctor if you have any doubts, as no list we make can be exhaustive and we don’t know your personal medical history, but the main culprits are:
- Cardiovascular disease
- Hypertension
- Diabetes (any type)
The first two are for heart attack risk; the latter is because diabetes can affect core temperature regulation.
Ice baths are good for the heart: True or False?
True or False depending on how they’re done, and your health before starting.
For most people, undertaking ice baths responsibly, repeated ice bath use causes the cardiovascular system to adapt to better maintain homeostasis when subjected to thermal shock (i.e. sudden rapid changes in temperature).
For example: Respiratory and cardiovascular responses to cold stress following repeated cold water immersion
And because that was a small study, here’s a big research review with a lot of data; just scroll to where it has the heading“Specific thermoregulative adaptations to regular exposure to cold air and/or cold water exposure“ for many examples and much discussion:
Health effects of voluntary exposure to cold water: a continuing subject of debate
Ice baths are good against inflammation: True or False?
True! Here’s one example:
Uric acid and glutathione levels (important markers of chronic inflammation) are also significantly affected:

Tasty Hot-Or-Cold Soup
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.
Full of fiber as well as vitamins and minerals, this versatile “serve it hot or cold” soup is great whatever the weather—give it a try!
You will need
- 1 quart low-sodium vegetable stock—ideally you made this yourself from vegetable offcuts you kept in the freezer until you had enough to boil in a big pan, but failing that, a large supermarket will generally be able to sell you low-sodium stock cubes.
- 2 medium potatoes, peeled and diced
- 2 leeks, chopped
- 2 stalks celery, chopped
- 1 large onion, diced
- 1 large carrot, diced, or equivalent small carrots, sliced
- 1 zucchini, diced
- 1 red bell pepper, diced
- 1 tsp rosemary
- 1 tsp thyme
- ¼ bulb garlic, minced
- 1 small piece (equivalent of a teaspoon) ginger, minced
- 1 tsp red chili flakes
- 1 tsp black pepper, coarse ground
- ½ tsp turmeric
- Extra virgin olive oil, for frying
- Optional: ½ tsp MSG or 1 tsp low-sodium salt
About the MSG/salt: there should be enough sodium already from the stock and potatoes, but in case there’s not (since not all stock and potatoes are made equal), you might want to keep this on standby.
Method
(we suggest you read everything at least once before doing anything)
1) Heat some oil in a sauté pan, and add the diced onion, frying until it begins to soften.
2) Add the ginger, potato, carrot, and leek, and stir for about 5 minutes. The hard vegetables won’t be fully cooked yet; that’s fine.
3) Add the zucchini, red pepper, celery, and garlic, and stir for another 2–3 minutes.
4) Add the remaining ingredients; seasonings first, then vegetable stock, and let it simmer for about 15 minutes.
5) Check the potatoes are fully softened, and if they are, it’s ready to serve if you want it hot. Alternatively, let it cool, chill it in the fridge, and enjoy it cold:
Enjoy!

Grapefruit vs Lemon – Which is Healthier?
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.
Our Verdict
When comparing grapefruit to lemon, we picked the lemon.
Why?
Grapefruit has its merits, but in the battle of the citrus fruits, lemons come out on top nutritionally:
In terms of macros, grapefruit has more carbs while lemons have more fiber. So, while both have a low glycemic index, lemon is still the winner by the numbers.
Looking at the vitamins, here we say grapefruit’s strengths: grapefruit has more of vitamins A, B2, B3, and choline, while lemon has more of vitamins B6 and C. So, a 4:2 win for grapefruit here.
In the category of minerals, lemons retake the lead: grapefruit has more zinc, while lemon has more calcium, copper, iron, manganese, and selenium.
One final consideration that’s not shown in the nutritional values, is that grapefruit contains high levels of furanocoumarin, which can inhibit cytochrome P-450 3A4 isoenzyme and P-glycoptrotein transporters in the intestine and liver—slowing down their drug metabolism capabilities, thus effectively increasing the bioavailability of many drugs manifold.
This may sound superficially like a good thing (improving bioavailability of things we want), but in practice it means that in the case of many drugs, if you take them with (or near in time to) grapefruit or grapefruit juice, then congratulations, you just took an overdose. This happens with a lot of meds for blood pressure, cholesterol (including statins), calcium channel-blockers, anti-depressants, benzo-family drugs, beta-blockers, and more. Oh, and Viagra, too. Which latter might sound funny, but remember, Viagra’s mechanism of action is blood pressure modulation, and that is not something you want to mess around with unduly. So, do check with your pharmacist to know if you’re on any meds that would be affected by grapefruit or grapefruit juice!
PS: the same substance is quite available in pummelos and sour oranges (but not meaningfully in sweet oranges); you can see a chart here showing the relative furanocoumarin contents of many citrus fruits, or lack thereof as the case may be, as it is for lemons and most limes)
Adding up the sections gives us a clear win for lemons, but by all means enjoy either or both; just watch out for that furanocoumarin content of grapefruit if you’re on any meds affected by such (again, do check with your pharmacist, as our list was far from exhaustive—and yes, this question is one that a pharmacist will answer more easily and accurately than a doctor will).

Three Daily Servings of Beans?
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 Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝Not crazy about the Dr.s food advice. Beans 3X a day?❞
For reference, this is in response to our recent article on the topic of 12 things to aim to get a certain amount of each day:
So, there are a couple of things to look at here:
Firstly, don’t worry, it’s a guideline and an aim. If you don’t hit it on a given day, there is always tomorrow. It’s just good to know what one is aiming for, because without knowing that, achieving it will be a lot less likely!
Secondly, the beans/legumes/pulses category says three servings, but the example serving sizes are quite small, e.g. ½ cup cooked beans, or ¼ cup hummus. And also as you notice, dips/pastes/sauces made from beans count too. So given the portion sizes, you could easily get two servings in by breakfast (and two servings of whole grains, too) if you enjoy frijoles refritos, for example. Many of the recipes we share on this site have “stealth” beans/legumes/pulses in this fashion
Take care!

Ramadan is almost here. 5 tips to boost your wellbeing and energy levels if you’re fasting
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.
Ramadan is one of the most significant months of the Islamic lunar calendar. It marks the time when the Quran was revealed to Prophet Mohammed (peace be upon him).
Almost 2 billion Muslims worldwide observe this month of prayer and reflection, which includes fasting between two prayers, Fajr at dawn and Maghrib at sunset.
Ramadan is about purifying the mind, body and soul, and practising self-restraint. It’s a time for spiritual growth and dedication to God (or Allah in Arabic). Ramadan also brings people together for meals and celebrations, with a focus on helping those less fortunate.
Depending on where you live, Ramadan can mean going 12 to 19 hours without eating or drinking anything, including water.
Our research shows choosing balanced, nutrient-dense foods and drinks can result in better wellbeing and greater energy levels than following your usual diet during Ramadan.
Here’s what to consider if you’re fasting for Ramadan.
Drazen Zigic/Shutterstock Do you have any health issues?
Healthy Muslims are expected to fast during Ramadan once they have reached puberty.
Frail older adults are exempt from fasting, as are pregnant, breastfeeding and menstruating women. Anyone who cannot participate in fasting can make up for the missed fasting days later.
People with chronic illness or mental health may be exempt if fasting poses a risk to their health. If you suffer from chronic illness, such as diabetes, heart disease or kidney problems, and want to fast, consult your GP first.
Fasting can have severe health consequences for people with certain medical conditions and those who rely on prescription medication. Some medications need to be taken at a specific time (and some with food) to be safe and effective.
If you’re not drinking enough water during Ramadan, your body might also handle some medications differently: they may not work as well or cause side effects.
For people who can safely fast, here are five tips to maintain your wellbeing during Ramadan.
1. Plan ahead
In preparation for Ramadan, stock up on essentials. Plan your meals and hydration in advance, to stay on top of your nutritional intake.
Start reducing your caffeine gradually in the week leading to Ramadan, so your body can adjust. This can help prevent or reduce the fasting headaches that many experience at the beginning of Ramadan.
Move your meals gradually towards Suhoor and Iftar times, so your body gets used to the new mealtimes.
Plan your meals ahead of time. Ground Picture/Shutterstock 2. Stay hydrated
Staying hydrated is important during Ramadan. Women should aim to drink 2.1 litres of water or fluids (such as coconut water, clear soups, broths or herbal teas) each day. Men should aim for 2.6 litres.
Limit the intake of sugary or artificially sweetened drinks and enjoy fresh fruit juice only in moderation. Sugary drinks cause a rapid increase in blood sugar levels. The body responds by releasing insulin, causing a drop in blood sugar, which can leave you feeling fatigued, irritable and hungry.
Increase your hydration by including water-rich foods, such as cucumbers and watermelon, in your diet.
3. Get your nutrients early
Before dawn, have a nutrient-rich, slow-digesting meal, along with plenty of water.
Select healthy nutrient-dense food with proteins and fats from lean meats, fish, chickpeas, tofu, nuts and seeds.
Choose whole grain products, a variety of vegetables and fruits, and fermented foods, such as kimchi and pickles, which can support your digestion.
When you prepare your meals, consider grilling, steaming or air frying instead of deep frying.
Stay away from processed foods such as cakes, ice cream, chips and chocolates, as they often lack essential nutrients and are high in sugar, salt and fat. Processed foods also tend to be low in fibre and protein, which are crucial for maintaining a feeling of fullness.
4. Avoid the temptation to overeat in the evening
At sunset, many Muslims come together with family and friends for the fast-breaking evening meal (Iftar). During these occasions, it may be tempting to overindulge in sweets, salty snacks and fatty dishes.
But overeating can strain the digestive system, cause discomfort and disrupt sleep.
Start with something small. Tekkol/Shutterstock Instead, listen to your body’s signals, control your portions, and eat mindfully – this means slowly and without distractions.
Start with something small, such as a date and a glass of water. You may choose to complete the Maghrib prayer before returning for your main meal and more fluids.
5. Keep moving
Finally, try to include some light exercise into your schedule, to maintain your fitness and muscle mass, and promote sleep.
But avoid heavy workouts, sauna and intensive sports while fasting, as these may increase dehydration, which can increase your risk of feeling faint and falling.

Stop Trying To Lose Weight (And Do This Instead)
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.
“Lose weight” is a common goal of many people, and it’s especially a common goal handed down from medical authority figures, often as a manner of “kicking the can down the road” with regard to the doctor actually having to do some work. “Lose 20 pounds and then we’ll talk”, etc.
The thing is, it’s often not a very good or helpful goal… Even if it would be healthy for a given person to lose weight. Instead, biochemist Jessie Inchauspé argues, one should set a directly health-giving goal instead, and let any weight loss, if the body agrees it is appropriate, be a by-product of that
She recommends focusing on metabolic health, specifically, her own specialism is blood glucose maintenance. This is something that diabetics deal with (to one degree or another) every day, but it’s something whose importance should not be underestimated for non-diabetics too.
Keep our blood sugar levels healthy, she says, and a lot of the rest of good health will fall into place by itself—precisely because we’re not constantly sabotaging our body (first the pancreas and liver, then the rest of the body like dominoes).
To that end, she offers a multitude of “hacks” that really work.
Her magnum opus, “Glucose Revolution“, explains the science in great detail and does it very well! Not to be mistaken for her shorter, simpler, and entirely pragmatic “do this, then this”-style book, “The Glucose Goddess Method”, which is also great, but doesn’t go into the science more than absolutely necessary; it’s more for the “I’ll trust you; just tell me what I need to know” crowd.
In her own words:

Give Your Adrenal Glands A Chance
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 Hats Of Wrath
Your adrenal glands are two little hat-shaped glands that sit on top of your kidneys (like your kidneys are wearing them as hats, in fact).
They produce adrenaline, as you might have guessed, and also cortisol and aldosterone, which you might or might not have known, as well as some miscellaneous corticosteroids that are beyond the scope of today’s article.
Fun fact! For a long time, doctors thought adrenal glands were much larger than they usually are, because of learning anatomy from corpses that were dissected, but invariably the corpses were those of poor people, especially criminals, whose adrenal glands were almost always overworked and swollen.
You don’t want yours to be like that.
What goes wrong
Assuming you don’t have a rare disorder like Addison’s disease (in which the adrenal glands don’t produce enough of the hormones they’re supposed to), your adrenal glands will usually not have trouble producing enough adrenaline et al.
However, as we learned from the Victorian vagabonds, they can also have no problems producing too much—much like any organ that gets overworked, however, this has consequences.
Hopefully you’re not living a life of stressful crime on the streets, but maybe you have other reasons your adrenal glands are working overtime, such as any source of chronic stress, bad sleep (can’t recharge without this downtime), overuse of stimulants (including caffeine and/or nicotine), and, counterintuitively, alcohol. All these things can tax the adrenal glands considerably.
When this happens, in the extreme we can get Cushing’s syndrome, characterized by the symptoms: hypertension, cortisol-based fat distribution i.e. especially face and abdomen, weakness, fragile easily irritable skin, hair loss and/or hirsutism, paradoxically, and of course general fatigue.
In the non-extreme, we get all the same symptoms just to a lower level, and experience what the medical profession is begging us not to call “Adrenal Fatigue Syndrome” because that’s not an official diagnosis, whereas if it gets a name then they’ll be expected to treat it.
What keeps things going right
Obviously, the opposite of the above, for a start. Which means:
Manage chronic stress; see: How To Manage Chronic Stress
Get good sleep; see: Why You Probably Need More Sleep
Go easy on the caffeine; see: Caffeine Mythbusting
Skip the nicotine; see: Nicotine Benefits (That We Don’t Recommend)!
Avoid alcohol; see: How To Reduce Or Quit Alcohol
There are specific vitamins and minerals that support adrenal health too; they are: vitamins B5, B6, B12, C, & D, and also magnesium and zinc.
Good dietary sources of the above include green leafy things, cruciferous vegetables*, nuts and seeds, avocados, olive oil, and if you eat fish, then also fatty fish.
In contrast, it is good to cut down (or avoid entirely) red meat and unfermented dairy.
*Unsure how to get cruciferous vegetables in more often? Try today’s featured recipe, superfood broccoli pesto

A large part of adrenal health is about keeping cortisol levels down generally (except: for most of us, we can have a little hormesis, as a treat), so for the rest of that you might like to read:
