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 😎
❝I keep seeing advice that we shoudl wear sunscreen out in winter even if it’s not hot or sunny, but is there actually any real benefit to this?❞
Short answer: yes (but it’s indeed not as critical as it is during summer’s hot/sunny days)
Longer answer: first, let’s examine the physics of summer vs winter when it comes to the sun…
In summer (assuming we live far enough from the equator to have this kind of seasonal variation), the part of the planet where we live is tilted more towards the sun. This makes it closer, and more importantly, it’s more directly overhead during the day. The difference in distance through space isn’t as big a deal as the difference in distance through the atmosphere. When the sun is more directly overhead, its rays have a shorter path through our atmosphere, and thus less chance of being blocked by cloud cover / refracted elsewhere / bounced back off into space before it even gets that far.
In winter, the opposite of all that is true.
Morning/evening also somewhat replicate this compared to midday, because the sun being lower in the sky has a similar effect to seasonal variation causing it to be less directly overhead.
For this reason, even though visually the sun may be just as bright on a winter morning as it is on a summer midday, the rays have been filtered very differently by the time they get to us.
This is one reason why you’re much less likely to get sunburned in the winter, compared to the summer (others include the actual temperature difference, your likely better hydration, and your likely more modest attire protecting you).
However…
The reason it is advisable to wear sunscreen in winter is not generally about sunburn, and is rather more about long-term cumulative skin damage (ranging from accelerated aging to cancer) caused by the UV rays—specifically, mostly UVA rays, since UVB rays (with their higher energy but shorter wavelength) have nearly all been blocked by the atmosphere.
Here’s a good explainer of that from the American Cancer Society:
UV (Ultraviolet) Radiation and Cancer Risk
👆 this may seem like a no-brainer, but there’s a lot explained here that demystifies a lot of things, covering ionizing vs non-ionizing radiation, x-rays and gamma-rays, the very different kinds of cancer caused by different things, and what things are dangerous vs which there’s no need to worry about (so far as best current science can say, at least).
Consequently: yes, if you value your skin health and avoidance of cancer, wearing sunscreen when out even in the winter is a good idea. Especially if your phone’s weather app says the UV index is “moderate” or above, but even if it’s “low”, it doesn’t hurt to include it as part of your skincare routine.
But what if sunscreens are dangerous?
Firstly, not all sunscreens are created equal:
Learn more: Who Screens The Sunscreens?
Secondly: consider putting on a protective layer of moisturizer first, and then the sunscreen on top. Bear in mind, this is winter we’re talking about, so you’re probably not going out in a bikini, so this is likely a face-neck-hands job and you’re done.
What about vitamin D?
Humans evolved to have more or less melanin in our skin depending on where we lived, and white people evolved to wring the most vitamin D possible out of the meagre sun far from the equator. Black people’s greater melanin, on the other hand, offers some initial protection against the sun (but any resultant skin cancer is then more dangerous than it would be for white people if it does occur, so please do use sunscreen whatever your skintone).
Nowadays many people live in many places which may or may not be the places we evolved for, and so we have to take that into account when it comes to sun exposure.
Here’s a deeper dive into that, for those who want to learn:

How To Escape From A Despairing Mood
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 we are in a despairing mood, that’s when it can feel hardest to actually implement anything we know about getting out of one. That’s why sometimes, the simplest solutions are the best:
Imagination Is Key
Despairing moods occur when it’s hard to envision a better life. Imagination is the power to envision alternatives, such as new jobs, relationships, or lifestyle, but sadness can cloud our ability to imagine solutions like changing careers, moving house, or starting fresh. With enough imagination, most problems can be worked around—and new opportunities can always be found.
Importantly: we are not bound by our past or present circumstances; we have the freedom and flexibility to choose new paths. That doesn’t mean it’ll always be a walk in the park, but “this too shall pass”.
You may be thinking: “sometimes the hardship does pass, but can last many years”, and that is true. All the more reason to check if there’s a freer lane you can slip into to speed ahead. Even if there isn’t, the mere act of imagining such lanes is already respite from the hardships—and having envisioned such will make it much easier for you to recognise when opportunities for change do come along.
To foster imagination, we are advised to expose ourselves to different narratives, preparing ourselves for alternative ways of living. Thus, we can reframe life’s challenges as intellectual puzzles, urging us to rebuild creatively and find new solutions!

The Coffee-Cortisol Connection, And Two Ways To Tweak It For Health
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.
Health opinions on coffee vary from “it’s an invigorating, healthful drink” to “it will leave you a shaking frazzled wreck”. So, what’s the truth and can we enjoy it healthily? Dr. Alan Mandell weighs in:
Enjoy it, but watch out!
Dr. Mandell is speaking only for caffeinated coffee in this video, and to this end, he’s conflating the health effects of coffee and caffeine. A statistically reasonable imprecision, since most people drink coffee with its natural caffeine in, but we’ll make some adjustment to his comments below, to disambiguate which statements are true for coffee generally, and which are true for caffeine:
- Drinking
coffeecaffeine first thing in the morning may not be ideal due to dehydration from overnight water loss. Coffeecaffeine is a diuretic, which means an increase in urination, thus further dehydrating the body.- Coffee contains great antioxidants, which are of course beneficial for the health in general.
- Cortisol, the body’s stress hormone, is generally at its peak in the morning. This is, in and of itself, good and correct—it’s how we wake up.
Coffeecaffeine consumption raises cortisol levels even more, leading to increased alertness and physical readiness, but it is possible to have too much of a good thing, and in this case, problems can arise because…- Elevated cortisol from early
coffeecaffeine drinking can build tolerance, leading to the need for morecoffeecaffeine over time. - It’s better, therefore, to defer drinking
coffeecaffeine until later in the morning when cortisol levels naturally drop. - All of this means that drinking
coffeecaffeine first thing can disrupt the neuroendocrine system, leading to fatigue, depression, and general woe. - Hydrate first thing in the morning before consuming
coffeecaffeine to keep the body balanced and healthy.
What you can see from this is that coffee and caffeine are not, in fact, interchangeable words, but the basic message is clear and correct: while a little spike of cortisol in the morning is good, natural, and even necessary, a big spike is none of those things, and caffeine can cause a big spike, and since for most people caffeine is easy to build tolerance to, there will indeed consistently be a need for more, worsening the problem.
In terms of hydration, it’s good to have water (or better yet, herbal tea) on one’s nightstand to drink when one wakes up.
If coffee is an important morning ritual for you, consider finding a good decaffeinated version for at least your first cup (this writer is partial to Lavazza’s “Dek Intenso”—which is not the same as their main decaf line, by the way, so do hold out for the “Dek Intenso” if you want to try my recommendation).
Decaffeinated coffee is hydrating and will not cause a cortisol spike (unless for some reason you find coffee as a concept very stressful in which case, yes, the stressor will cause a stress response).
Anyway, for more on all of this, enjoy:

Crispy Tofu Pad Thai
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.
Easy to make, delicious to enjoy, and packed with phytonutrients, this dish is a great one to add to your repertoire:
You will need
- 10 oz ready-to-wok rice noodles, or 6 oz dry
- 5 oz silken tofu
- 5 oz firm or extra firm tofu, cut into small cubes
- 1 oz arrowroot (or cornstarch if you don’t have arrowroot)
- 4 scallions, sliced
- ¼ bulb garlic, finely chopped
- 1″ piece fresh ginger, grated
- 1 red chili, chopped (multiply per your heat preferences)
- 1 red bell pepper, deseeded and thinly sliced
- 4 oz bok choi, thinly sliced
- 4 oz mung bean sprouts
- 1 tbsp tamari (or other, but tamari is traditional) soy sauce
- 1 tbsp sweet chili sauce
- Juice of ½ lime
- ½ tsp MSG or 1 tsp low-sodium salt
- Avocado oil, or your preferred oil for stir-frying
- To serve: lime wedges
- Optional garnish: crushed roasted peanuts (if allergic, substitute sesame seeds; peanuts are simply traditional, that’s all)
Method
(we suggest you read everything at least once before doing anything)
1) Scramble the silken tofu. For guidance and also additional seasoning pointers, see our Tasty Tofu Scramble recipe, but omit the thyme.
2) Cook the noodles if necessary (i.e. if they are the dry type and need boiling, as opposed to “ready-to-wok” noodles that don’t), drain, and set aside.
4) Prepare the tofu cubes: if the tofu cubes are dry to the touch, toss them gently in a little oil to coat. If they’re wet to the touch, no need. Dust the tofu cubes with the arrowroot and MSG/salt; you can do this in a bowl, tossing gently to distribute the coating evenly.
4) Heat some oil in a wok over a high heat, and fry the tofu on each side until golden and crispy all over, and set aside.
5) Stir-fry the scallions, garlic, ginger, chili, and bell pepper for about 2 minutes.
6) Add the bean sprouts and bok choi, and keep stir-frying for another 2 minutes.
7) Add everything that’s not already in the pan except the lime wedges and peanuts (i.e., add the things you set aside, plus the remaining as-yet-untouched ingredients) and stir-fry for a further 2 minutes.
8) Serve hot, garnished with the crushed peanuts if using, and with the lime wedges on the side:
Enjoy!

Holistic Approach To Resculpting A Face Affected By Hypothyroidism, PCOS, Or Menopause
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.
Mila Magnani has PCOS and hypothyroidism, but the principles are the same for menopause because both menopause and PCOS are a case of a hormone imbalance resulting in androgenic effects, so there’s a large amount of overlap.
Obviously, a portion of the difference in the thumbnail is a matter of angle and make-up, but as you can see in the video itself, there’s also a lot of genuine change underneath, too:
Stress-free method
Firstly, she bids us get lab tests and work with a knowledgeable doctor to address potential thyroid, hormonal, or nutrient imbalances. Perhaps we already know at least part of what is causing our problems, but even if so, it doesn’t hurt to take steps to rule the others out. Imagine spending ages unsuccessfully battling PCOS or menopause, only to discover it was a thyroid issue, and you were fighting the wrong battle!
Magnani used a natural route to manage her PCOS and hypothyroidism, while acknowledging that medication is fine too; it’s usually cheaper and more convenient—and there’s a lot more standardization for medications than there is for supplements, which makes it a lot easier to navigate, find what works, and keep getting the exact same thing once it does work.
Other things she recommends include:
- Lymphatic drainage: addressing the lymphatic system to reduce puffiness. Techniques include lymphatic drainage massage, stretching, rebounding (trampoline), and dry brushing. She emphasizes that for facial de-puffing, it’s important to treat the whole upper body, not just the face.
- Low-impact exercise: she switched from high-intensity workouts to low-impact exercises like nature walking and gentle stretching to reduce stress and improve health.
- Nervous system regulation: she worked on nervous system regulation by means of journaling, breathwork, and stimulating the vagus nerve, which improved sleep and reduced stress and anxiety. These things, of course, have knock-on benefits for almost every part of health.
- Diet: she adopted a low-glycemic diet, reduced salt intake, and cooked at home to avoid water retention caused by high sodium in restaurant meals.
- Natural diuretics: she uses teas like hibiscus and chamomile to reduce puffiness after consuming high-sodium foods.
- Sauna and sweating: consider a sauna mat or hot baths to detox and reduce swelling; that’s what she uses in lieu of a convenient sauna.
You may be wondering how quickly you can expect results: it took 3–6 months of daily effort to see significant changes, and she now maintains the routine less frequently (every 2–3 days, instead of daily).

Pistachios vs Pecans – 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 pistachios to pecans, we picked the pistachios.
Why?
Firstly, the macronutrients: pistachios have twice as much protein and fiber. Pecans have more fat, though in both of these nuts the fats are healthy.
The category of vitamins is an easy win for pistachios, with a lot more of vitamins A, B1, B2, B3, B6, B9, C, and E. Especially the 8x vitamin A, 7x vitamin B6, 4x vitamin C, and 2x vitamin E, and as the percentages are good too, these aren’t small differences. Pecans, meanwhile, boast only a little more vitamin B5 (pantothenic acid, the one whose name means “it’s everywhere”, because that’s how easy it is to get it).
In terms of minerals, pistachios have more calcium, iron, phosphorus, potassium, and selenium, while pecans have more manganese and zinc. So, a fair win for pistachios on this one.
Adding up the three different kinds of win for pistachios means that *drumroll* pistachios win overall, and it’s not close.
As ever, do enjoy both though, because diversity is healthy!

Is Air-Fried Food Really 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.
Air-frying has a reputation for being healthy—and it generally is, provided it’s used carefully:
Just one thing to watch out for
An air-fryer is basically a small convection oven that uses circulating air rather than immersion in oil to cook food. The smallness of an air-fryer is a feature not a bug—if you get an air-fryer over a certain size, then congratulations, you just have a convection oven. The small size it what helps it to cook so efficiently. This is one reason that they’re not really used in industrial settings.
The documentary-makers from this video had their food (chicken, fish, and fries) lab-tested (for fat, cholesterol, and acrylamide), and found:
- Air-frying significantly reduced saturated fat (38–53%) and trans fats (up to 55%) in some foods.
- Cholesterol reduction varied depending on the food type.
- Acrylamide levels in air-fried potatoes were much higher due to cooking time and temperature.
About that acrylamide: acrylamide forms in starchy foods at high temperatures and may pose cancer risks (the research is as yet unclear, with conflicting evidence). Air-frying can cause higher acrylamide levels if cooking is prolonged or temperatures are too high.
Recommendations to reduce acrylamide:
- Soak potatoes before cooking.
- Use lower temperatures (e.g. 180℃/350℉) and shorter cooking times.
- Avoid over-browning food.
