The colder, darker months can take a toll on well-being. Two out of five U.S. adults say their mental health worsens in the winter. Plus, about five percent of U.S. adults experience seasonal affective disorder (SAD), a type of depression induced by seasonal changes that typically begins when the weather gets colder and there’s less daylight.

Fortunately, there are science-backed lifestyle changes that can make this time of year more tolerable. Here’s how to take care of your mental health this winter.

Exercise regularly

When you exercise, your body releases endorphins, or “feel-good” chemicals that can improve your mood. A 2024 review of studies found that exercise—particularly walking, jogging, yoga, and strength training—can reduce symptoms of depression.

Before starting a new exercise routine, talk to your health care provider about the types of exercise that may work best for you.

Get outside

While getting outside during the colder months may feel challenging, time outdoors—especially in nature—has been shown to decrease stress, depression, and anxiety. Plus, sunlight helps your body make vitamin D, which may improve your energy and mood.

You can reap the benefits of nature no matter where you live.

“Cities can be very energetic and exciting but also can contribute to both conscious and unconscious stress from the sensory overload and challenges of maneuvering in those spaces,” said Jodie M. Smith, a Mayo Clinic nurse practitioner, in a 2024 Mayo Clinic article. “If you live in an urban environment, exploring to find even a small natural reprieve can be extremely beneficial.”

Prioritize sleep

Inadequate sleep has been linked to depression and anxiety. Taking steps to improve the quality and duration of your sleep can help you become more resilient against stressors.

You can improve your sleep by going to bed and waking up at the same time every day; avoiding caffeine, alcohol, and large meals before bed; keeping your bedroom cool and dark; and limiting exposure to distressing media in the evening.

Practice gratitude

Research suggests that people who practice gratitude are less likely to experience depression. It can also help you make lifestyle changes that improve your well-being overall.

“Practicing gratitude may also make someone a bit more motivated to take care of their health,” said Tyler VanderWeele, co-director of the Initiative on Health, Spirituality, and Religion at the Harvard T.H. Chan School of Public Health, in a 2024 Harvard Health Publishing article. “Maybe they’re more likely to show up for medical appointments or exercise. It may also help with relationships and social support, which we know contribute to health.”

Add more gratitude to your life by sharing what you’re grateful for with others or keeping a gratitude journal.

Spend quality time with loved ones

“Social isolation and loneliness have a serious impact on physical and mental health, quality of life, and longevity,” according to the World Health Organization, with effects comparable to other risk factors like smoking.

Research shows that people who have close confidants are more satisfied with their lives and less likely to experience depression. Even after holiday gatherings have ended, schedule time with friends and family to stay positive and feel supported.

Limit cell phone use

Social media use and “doomscrolling” inflammatory news headlines are both associated with anxiety and depression across age groups, especially in teens.

“Excessive social media use is associated with behaviors, such as poor sleep, increased social comparisons, impact on learning, and exposure to cyberbullying and negative content, that could contribute to the worsening of depressive symptoms,” Dr. Carol Vidal, an assistant professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine, said in a Hopkins Medicine article.

Minimize the time you and your family members spend on your phones by pausing notifications, keeping your phone out of reach when you’re preparing for sleep, using a “grayscale” setting to make scrolling less enticing, and finding phone-free hobbies to enjoy.

Light therapy

Light therapy is one treatment for people who have been diagnosed with SAD. It involves sitting in front of a bright light box for 30 to 45 minutes per day to increase light exposure.

This treatment may not be right for people who take certain medications or have eye diseases. Talk to your health care provider about whether light therapy is right for you and what type of light box you should use.

Seek professional support

If your mental health over the winter interferes with your daily functioning, seek help from a therapist, support group, or mental health hotline. Find resources here.

  • An Unexpected Extra Threat Of Alcohol

    If You Could Use Some Exotic Booze…

    …then for health reasons, we’re going to have to say “nay”.

    We’ve written about alcohol before, and needless to say, it’s not good:

    Can We Drink To Good Health?

    (the answer is “no, we cannot”)

    In fact, the WHO (which unlike government regulatory bodies setting “safe” limits on drinking, makes no profit from taxes on alcohol sales) has declared that “the only safe amount of alcohol is zero”:

    WHO: No level of alcohol consumption is safe for our health

    Up there, where the air is rarefied…

    If you’re flying somewhere this summer (Sinatra-style flying honeymoon or otherwise), you might want to skip the alcohol even if you normally do imbibe, because:

    ❝…even in young and healthy individuals, the combination of alcohol intake with sleeping under hypobaric conditions poses a considerable strain on the cardiac system and might lead to exacerbation of symptoms in patients with cardiac or pulmonary diseases.

    These effects might be even greater in older people; cardiovascular symptoms have a prevalence of 7% of inflight medical emergencies, with cardiac arrest causing 58% of aircraft diversions.❞

    Source: Alcohol plus cabin pressure at higher altitude may threaten sleeping plane passengers’ heart health

    The experiment divided subjects into a control group and a study group; the study group were placed in simulated cabin pressure as though at altitude, which found, when giving some of them two small(we’re talking the kind given on flights) alcoholic drinks:

    ❝The combination of alcohol and simulated cabin pressure at cruising altitude prompted a fall in SpO2 to an average of just over 85% and a compensatory increase in heart rate to an average of nearly 88 beats/minute during sleep.

    In contrast, that was 77 beats/minute for those who had alcohol but weren’t at altitude pressure, or 64 beats/minute for those who neither drank nor were at altitude pressure.

    Lots more metrics were recorded and the study is interesting to read; if you’ve ever slept on a plane and thought “that sleep was not restful at all”, then know: it wasn’t just the seat’s fault, nor the engine, nor the recycled nature of the air—it was the reduced pressure causing hypoxia (defined as having oxygen levels lower than the healthy clinical norm of 90%) and almost halving your sleep’s effectiveness for a less than 10% drop in available oxygen in the blood (the sleepers not at altitude pressure averaged 96% SpO2, compared to the 85% at altitude).

    We say “almost halving” because the deep sleep phase of sleep was reduced from 84 minutes (control) to 67.5 minutes at altitude without alcohol, or 46.5 minutes at altitude with alcohol.

    Again, this was a pressure cabin in a lab—so this wasn’t about the other conditions of an airplane (seats, engine hundreds of other people, etc).

    Which means: in an actual airplane it’s probably even worse.

    Oh, and the study participants? All healthy individuals aged 18–40, so again probably worse for those older (or younger) than that range, or with existing health conditions!

    Our Verdict

    When comparing mango to guava, we picked the guava.

    Why?

    Looking at macros first, these two fruits are about equal on carbs (nominally mango has more, but it’s by a truly tiny margin), while guava has more than 3x the protein and more than 3x the fiber. A clear win for guava.

    In terms of vitamins, mango has more of vitamins A, E, and K, while guava has more of vitamins B1, B2, B3, B5, B7, B9, and C. Another win for guava.

    In the category of minerals, mango is not higher in any minerals, while guava is higher in calcium, copper, iron, magnesium, manganese, phosphorus, potassium, and zinc.

    In short, enjoy both; both are healthy. But if you’re choosing one, there’s a clear winner here, and it’s guava.

  • Ready to Run – by Kelly Starrett

    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.

    If you’d like to get into running, and think that maybe the barriers are too great, this is the book for you.

    Kelly Starrett approaches running less from an “eye of the tiger” motivational approach, and more from a physiotherapy angle.

    The first couple of chapters of the book are explanatory of his philosophy, the key component of which being:

    Routine maintenance on your personal running machine (i.e., your body) can be and should be performed by you.

    The second (and largest) part of the book is given to his “12 Standards of Maintenance for Running“. These range from neutral feet and flat shoes, to ankle, knee, and hip mobilization exercises, to good squatting technique, and more.

    After that, we have photographs and explanations of maintenance exercises that are functional for running.

    The fourth and final part of the book is about dealing with injuries or medical issues that you might have.

    And if you think you’re too old for it? In Starrett’s own words:

    ❝Problems are going to keep coming. Each one is a gift wanting to be opened—some new area of performance you didn’t know you had, or some new efficiency to be gained. The 90- to 95-year-old division of the Masters Track and Field Nationals awaits. A Lifelong commitment to solving each problem that creeps up is the ticket.

    In short: this is the book that can get you back out doing what you perhaps thought you’d left behind you, and/or open a whole new chapter in your life.

  • Capsaicin For Weight Loss And Against Inflammation

    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.

    Capsaicin’s Hot Benefits

    Capsaicin, the compound in hot peppers that makes them spicy, is a chemical irritant and a neurotoxin. However, humans being humans, we decided to eat them for fun.

    In contrast to many other ways in which humans recreationally enjoy things that are objectively poisonous, consuming capsaicin (in moderation) is considered to have health benefits, such as aiding weight loss (by boosting metabolism) and reducing inflammation.

    Let’s see what the science says…

    First: is it safe?

    Capsaicin is classified as “Generally Recognized As Safe”. That said, the same mechanism that causes them to boost metabolism, does increase blood pressure:

    Mechanisms underlying the hypertensive response induced by capsaicin

    If you are in good cardiovascular health, this increase should be slight and not pose any threat, unless for example you enter a chili-eating contest when not acclimated to such:

    Capsaicin and arterial hypertensive crisis

    As ever, if unsure, do check with your doctor first, especially if you are taking any blood pressure medications, or otherwise have known blood pressure issues.

    Does it really boost metabolism?

    It certainly does; it works by increasing oxygen consumption and raising body temperature, both of which mean more calories will be burned for the same amount of work:

    Dietary capsaicin and its anti-obesity potency: from mechanism to clinical implications

    This means, of course, that chili peppers enjoy the status of being functionally a “negative calorie” food, and a top-tier one at that:

    Chili pepper as a body weight-loss food

    Here’s a good quality study that showed a statistically significant* fat loss improvement over placebo:

    Capsaicinoids supplementation decreases percent body fat and fat mass: adjustment using covariates in a post hoc analysis

    *To put it in numbers, the benefit was:

    • 5.91 percentage points lower body fat percentage than placebo
    • 6.68 percentage points greater change in body fat mass than placebo

    See also: Difference between percentages and percentage points

    For those who prefer big reviews than single studies, we’ve got you covered:

    The Effects of Capsaicin and Capsiate on Energy Balance: Critical Review and Meta-analyses of Studies in Humans

    Does it really reduce inflammation?

    Counterintuitive as it may seem, yes. By means of reducing oxidative stress. Given that things that reduce oxidative stress tend to reduce inflammation, and in turn tend to reduce assorted disease risks (from diabetes to cancer to Alzheimer’s), this probably has more knock-on benefits too, but we don’t have room to explore all of those today.

    Fresh peppers are best for this, but dried peppers (such as when purchased as a ground spice in the supermarket, or when purchased as a capsule-based supplement) still have a very respectable anti-inflammatory effect:

    How much should we take?

    It’s recommended to start at a low dose and gradually increase it, but 2–6mg of capsaicin per day is the standard range used in studies.

    If you’re getting this from peppers, then for example cayenne pepper (a good source of capsaicin) contains around 2.5mg of capsaicin per 1 gram of cayenne.

    In the case of capsules, if for example you don’t like eating hot pepper, this will usually mean taking 2–6 capsules per day, depending on dosage.

    Make sure to take it with plenty of water!

    Where can we get it?

    Fresh peppers or ground spice from your local grocery store is fine. Your local health food store probably sells the supplements, too.

    If you’d like to buy it online, here is an example product on Amazon.

    Note: options on Amazon were more limited than usual, so this product is not vegan, and probably not halal or kosher, as the capsule contains an unspecified gelatin.

  • As The Summer Gets Hotter Still…

    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

    ❝I would love to see an article about heat dehydrated illness….so much of the US is under hot conditions. I had an fainting sweating episode and now trying to recoup from it. What should we do? Drink water,rest…???❞

    We have done some of this, but it’s always a good one to revisit! Last summer (N. Hemisphere summer), we wrote this:

    Stay Safe From Heat Exhaustion & Heatstroke!

    …and this year, it’s getting hotter still (and is already the hottest summer on record), with certainly much of the US seriously affected, as you say. Next year, it will probably be worse again; climate change is getting predictable like that, and likely will continue until fixed. We are but a health science publication, so we can’t fix the world’s climate, but we can reiterate the above advice, and urge everyone to take it seriously.

    Note: heat exhaustion and heatstroke kill. Yes, we’re including heat exhaustion in that, because by the time you get heat exhaustion, you’re often not in the best state of mind to take the correct steps to avoid the heatstroke that follows.

    To think otherwise would be akin to thinking “falling never killed anyone; it’s only when you stop falling that it’s dangerous”.

    This summer, we did also write this more niche article:

    Surviving Summer While Fat

    …whose advice won’t apply to everyone, but will be helpful to some, and honestly, some of that advice does go for everyone.

    One thing we didn’t write about in those articles that we’ll add here:

    Humidity is dangerous:

    • Dry heat: you sweat, the sweat evaporates, cooling you. As well as losing heat, you’ve also now lost water and salts, which you’ll need to replenish, but your body is operating correctly.
    • Humid heat: you sweat, and now you are just sweaty until further notice. It doesn’t evaporate because the surrounding humidity doesn’t provide the physics for that. Not only are you not losing heat through evaporating sweat, but also, if you’re wearing clothes, that’s now an insulating layer you’re wearing.

    …so that means, watch the humidity as carefully as you watch the temperature, and when it’s high, get extra serious about finding ways to keep yourself cool (e.g. shade, rest, cooling showers etc if you can, that kind of thing).

    Take care!
