    What Is Sweat? The Truth About Sweat and Exercise

    What most people already know is that sweating is our body’s way of cooling itself down during a workout or intense physical activity, or even a super stressful situation. So obviously, sweating while exercising is very normal. But for some, sweating can feel excessive and can lead to not-so-pleasant odors or stains on clothes. So let’s learn more about what sweat actually is and answer common questions about sweaty workouts.   Table of Contents:What is sweat?Like everything that has to do with our bodies, there’s a chemical makeup of sweat – it is made up mainly of water (H₂0) and salt (Na+), and contains sodium, potassium, and chloride ions.(1)Sweat is directly related to changes to the electrolyte balance in the body.(2) This is why adequate hydration is extremely important, so your body has the means to cool itself down.If you are dehydrated going into a workout — which means you did not drink enough beforehand — your body will not be able to cool itself down or regulate its core temperature properly. The same goes for replenishing lost fluid after an intense workout.If you do not compensate for your sweat loss with proper fluid intake, especially for those who are engaging in intense physical activity, a hypohydration state can occur as well as an overall increase in core body temperature.(3)Remember, sweat is water and salt, so you’ll want to properly hydrate – of course, with water as well as homemade electrolyte drinks or mindfully incorporating a bit of salt into your meals.Where does sweat come from?Sweat actually comes from two different types of sweat glands in the body. The eccrine glands are the ones responsible for cooling down the body when our body temperature rises. They are found all over the body and open directly on the surface of the skin, which then allows the sweat to evaporate, causing this cooling effect.Apocrine sweat glands, on the other hand, are found under the arms and in the groin area — areas where there are generally more concentrated hair follicles. These sweat glands are also triggered by increased body temperature but are mostly activated during times of stress, anxiety, or hormonal fluctuations. This sweat is a bit milkier and mixes with the bacteria on the skin, which creates the not-so-pleasant body odor.Why am I sweating so much? The amount that you sweat also depends on your weight, sex, fitness level, age, where you live (climate), and even your genetics. Scientifically speaking, sweating is a complex physiological response to activity, temperature, plasma volume, and sweat rate.(3) Sweating a lot during exerciseSweating during physical activity is completely normal, but the amount you sweat can depend on your fitness levels and overall physique. An overweight person is going to sweat more easily because the amount of energy needed to execute a particular activity is going to be higher. Additionally, a fitter person who works out regularly will begin to sweat faster than a not-so-fit person because the body is smart and is already prepared to sweat to cool itself down while training.Did you knowOne study found that a person who is perspiring from running has a higher level of electrolytes in their sweat than a person who is inactively sweating in a sauna. This means that even the chemical makeup of the sweat that is produced depends on the cause for the perspiration.(4)Sweating in the summerYou may have noticed that you break a sweat faster and sweat more when you exercise in the summer. This is completely normal — your body has to adjust to the heat and cool itself down more. So, in this case, more sweat is a positive reaction from your body.Sweating in the saunaAnother common place many people find themselves sweating a lot is in the sauna. A trip to the sauna is usually intended to get sweaty and burn calories while relaxing. But do you actually burn calories from sweating? We will answer this, and many other frequently asked questions in our Sweat 101 section below.  How to prepare for a sweaty workout:1. Drink EnoughMost people walk around chronically dehydrated! Be sure that you’re drinking enough water every day. This calculator will help you find out how much you should be drinking:And by the way, you should be drinking water even when you are not thirsty! The feeling of thirst is actually your body crying for help, not an initial signal. If you’re not sure whether you’re drinking enough, see if any of these 9 signs of dehydration apply to you.2. Remove cosmetics beforehandIf you want to really sweat, then wash off any makeup or lotions you may have put on throughout the day. Why? These can block the pores and prevent your body from cooling itself down. Blocked pores (especially on the face) during exercise can also increase blemishes. Wash it off quickly beforehand if you have time.3. Wear the right workout clothesThe most important thing to think about when choosing workout clothes is breathability. You’ll be happier training in moisture-wicking and breathable materials.Looking for an extra sweaty workout? Try this intense Wakanda Forever Workout on the adidas Training app. Sweat 101: The questions everyone asks1. Why do I sweat so much from my face and head when I exercise?Sweating from the face and head is quite common and is simply a result of overstimulated eccrine glands. There are factors outside of exercise that can also result in a sweaty face and head, includingcertain medicationsanxietyspicy foodshyperthyroidismmenopause substance abuse2. How much should I sweat when I work out?This is the golden question without a golden answer. Because simply put, nobody is the same so while one person may sweat a lot during an intense workout, another might not at all during the same workout. As we stated earlier, hydration also plays a role in how much we sweat, as well as fitness level, age, climate, skin, gender, etc. If you are concerned that you’re not sweating enough during exercise, try a heart-rate monitor to better gauge your fitness level and intensity of the workout. 3. Does sweating during exercise burn calories?Exercise burns calories, and sweating can be a result of exercising as it helps to cool the body down. But like we said before, not everyone sweats during exercise, while some sweat excessively during exercise. So the amount of sweat doesn’t always align with the intensity of the workout.However, sitting in the sauna can burn calories as the high temperatures cause your heart rate to increase. But if you’re looking to lose weight, this is not a very effective way as you will likely only lose water weight from sweating and put it back on when you rehydrate.Remember, activity is what burns calories. No matter how much or how little you sweat.4. Is it unhealthy not to sweat during exercise?As we’ve said before, everyone is different – from genetic makeup to how many sweat glands you have, no one is the same. So if you don’t sweat as much as someone else, that’s not to say there is a problem. It might just be that you have fewer sweat glands.But what is unhealthy is if your body is unable to cool itself down, leading to heatstroke, heat exhaustion, or heat cramps. If your body is not able to cool down internally, you may have a medical condition like anhidrosis or hypohidrosis, and in that case, you need to seek medical advice.Some final wordsSo now you know that the amount you sweat doesn’t only depend on the intensity of your workout but also on other factors. If you provide the right conditions and hydration for your body to sweat in a healthy way, it can cool down efficiently so that there’s nothing stopping you from embracing your sweaty workouts. *** More

    Filson x Ten Thousand Collection Is the Workhorse of Workout Apparel

    For duds that endure the wear and tear of wilderness excursions, Filson is a mainstay. For workout apparel that withstands grueling lifting sessions, Ten Thousand is a stalwart. Separately they shine, but together they can single-handedly replace your training kit with high-performance workout apparel.

    The two brands have joined forces to drop a limited-edition collection of workout clothes designed to meet the training needs of first responders and wildland firefighters.
    “Having FiIson ask us to help them make this collection is an incredible honor,” says Keith Nowak, founder and CEO of Ten Thousand. While Filson was born in the woods and Ten Thousand was born in the gym, we both share a spirit that’s been forged from hard work, grit and the will to become better than we were yesterday. And this collection encompasses that perfectly.”

    Courtesy ImageThe Filson x Ten Thousand Collection features three pieces—all made in Filson’s signature Marsh Olive colorway: Versatile Shirt, crafted from breathable, sweat-wicking, quick-drying, and abrasion-resistant fabric; the lined Tactical Short, cut from durable yet featherweight four-way stretch ripstop fabric; and Training Sock, which features cooling mesh panels, functional cushioning, and anatomical arch support.
    They all have a permanent silver ion treatment that will last through use and washing.

    Courtesy Image“Filson and Ten Thousand users share similar values and lifestyles,” says Alex Carleton, chief creative officer at Filson. “Both are smart, tough and prepared. The collaboration between the two brands resulted in a collection perfect for our everyday heroes… The design behind the collection was led by the athletes and heroes it was made for, like frogman combat veteran and backcountry hunter, Alex Fitchler, who helped put the collection through its paces.”
    Courtesy ImageThe standout among the pieces has to the be the swim-ready shorts, which were made to conform to the needs of military fitness standards by being durable, breathable, and lightweight. But they also had to be easy to wash, odor-resistant, comfortable, and feature multiple pockets. The Tactical Short shines in the last aspect, as they have stash spots, inside and out, that offer secure storage for items like cash, keys, smartphone, ID, and energy chews.
    The Filson x Ten Thousand Collection will be available from and beginning Friday, October 29, 2021. Prices start at $16.

    Best Infrared Light Devices for Hair Loss, Workout Recovery, and More

    For at least a decade, doctors, physiotherapists, and chiropractors have used infrared light therapy to heal injured muscles and treat conditions like Parkinson disease, depression, and even cancer. Now, the benefits are not just for the lettered. You can buy at-home infrared light devices to help manage everything from injuries to blood pressure, hair loss to wrinkles. Question is, while infrared light devices promise to be a medical panacea, they cost thousands of dollars. Are they worth it?
    The devices vary in size, shape, and function, but all use infrared LED lights, either invisible near infrared (NIR) or visible red infrared (RI). No one is entirely sure what these lights do in the human body, but scientists believe they penetrate our cells, activating the mitochondria, our cells’ power plant. Energizing these mitochondrion make cells healthier, encouraging repair processes.NASA started studying artificial light therapy in the 1980s and the research has increased in recent years with improvements in LED light technology. Anecdotal and scientifically gathered data links NIR and RI to all kinds of health and healing benefits, but the research is limited in scale, says Brent Bauer, research director for the Integrative Medicine Program at the Mayo Clinic in Minnesota.“We’re still waiting for reliable, large-scale studies to validate some of these claims,” he says. “Until we have some good-quality studies that evaluate both the efficacy and safety of these new devices, caution is prudent.”He does acknowledge NIR and RI light are different than the kind of skin-damaging energy used in tanning beds or solar UV rays. Used moderately, there are few side effects or risks associated with infrared light devices.Weighed against the growing list of benefits, it’s worth taking a closer look at some of the options available. Here are the top options to consider. More

    Can WHOOP Strap 3.0 Replace a Personal Trainer?

    This article was produced in partnership with WHOOP. 
    We’re hardwired to think getting fitter, faster, and stronger requires high-octane efforts all the time. If you’re not limping around post-leg day, it’s not contributing to your gains. If you’re not gassed by the end of your runs, you won’t hit a personal best. But if there’s one thing you should work toward in 2021, it’s training smarter. With a wearable like WHOOP Strap 3.0, you can monopolize your health and fitness data to see how your daily workout intensity in conjunction with work and life stress impacts your body’s ability to recover. It’s like having a personal trainer on your wrist.
    WHOOP Strap 3.0 Courtesy Image
    How WHOOP Measures Daily Strain and Recovery
    WHOOP scientists pored over a million different days of “Strain” and “Recovery” metrics from users to see exactly how they impacted peoples’ heart rate variability (HRV) the following day. Quick primer: HRV measures fluctuations in time between heartbeats. At rest, it can swing between, say, 55 and 65 beats per minute, since inhaling speeds up your heart rate while exhaling slows it down. A lower HRV means your body is struggling to handle stress and fatigue, while a higher HRV means your body is well-equipped to handle exertion. Since heart rate is the only objective measure of recovery, it’s WHOOP’s main deciding factor in how intensely you should be training on a day-to-day basis. To help users discern data, WHOOP scientists created the Strain metric to quantify overall stress put on your body. Based on your recovery each morning, WHOOP provides a target strain goal based on what your body is signaling it can handle for the day.

    Now that’s not to say you always want to be in the green. If you’re training for a triathlon, you’re likely going to have training blocks of intense exercise where you’re overreaching, in which you’re prioritizing fitness gains over full recovery. That’s necessary for your short-term goal. When you near race day, you’ll taper and enter a restoring phase to help your body recuperate before the big event. That’s also necessary for your short-term goal; if it’s a long-term pattern, however, you’ll begin to detrain and lose endurance and/or muscle mass, depending on what you’ve been training for. Likewise, if you’re hitting your max effort every single day, without taking time to fully recover, that can culminate in overtraining, injury, and exhaustion.
    On the app, there are two rings that indicate your strain and recovery for the day—a quick overview of your insights. Bigger efforts can be anywhere from a 14-19+ on the Strain scale, and it’s indicated as a blue line that inches closer to being “completed” depending on how close you get to your target strain (again, everything is relative; it’s not necessarily good or bad to hit the max). Your recovery is similarly presented as a circle within your Strain ring, although it’s color-coded to reflect the above Training Zones. Toggle to Strain, Recovery, and Sleep for a deeper dive into your analytics for the day and month (shown below).
    WHOOP app insights Courtesy of Brittany Smith
    Because WHOOP is combining yesterday’s Strain metrics with the night’s duration and quality of sleep, some athletes can naturally perform at a higher caliber—clocking more workouts at a higher intensity without teetering into the Overreaching zone if they’re also prioritizing optimal recovery. Sleep recharges your body. It regulates growth hormone to help build and repair muscle by healing those microtears caused during exercise; and regulates cortisol, the stress hormone, which can lead to inflammation in the body and inhibit recovery.

    Can a Strap Replace a Personal Trainer? It Can—If You Know How to Leverage Your WHOOP Data
    1. Do a Deep Dive Into Your Recovery
    When most individuals work with personal trainers, they’re not always honest about their diet, stress, sleeping habits, and how much they drink throughout the week. But WHOOP provides a subjective view of how your body is faring internally in ways a personal trainer could never infer. Based on recovery, having a target strain goal makes it easier to understand when you should aim to have a more intense workout or focus on rest and active recovery. The app creates a holistic picture that connects the dots between data and lifestyle behaviors so you can draw parallels and uncover what’s hindering your recovery.
    For example, in the monthly performance assessment (you can look over the year too), WHOOP breaks down your quality of sleep over the last 30 days. If your restorative sleep is on a downward trend, make a concerted effort to close the gap between the sleep you’re getting and what your body optimally needs. A coach or trainer would tell you to perfect your sleep hygiene, but won’t know what that means for you. Look at your nightly journal. If alcohol is wrecking your recovery, rethink how and when you drink. Maybe you save the beers for your recovery day, rather than the night before a strenuous workout. (Also check out these science-backed natural sleep aids experts swear by.) Take sleep as seriously as you do your workouts, and you’ll unlock new levels of athletic potential.
    2. Use Strain to Measure Stress in and out of Training
    Most wearables track calories, steps, distance, and pace. But workouts impact us all differently based on how fit we are and our body’s ability to perform. With the Strain metric, WHOOP helps quantify how strenuous your workout and day is based on your fitness level. For example, running a 5K for an advanced runner might register as a light strain of 7-9, but it might be closer to a 14-17 for someone new to running. The distance is still the same, but the effort required from the body is different in each case. WHOOP is unique in that it helps quantify this type of stress on an individual level. You’ll learn which of those are true for you by clocking different types of workouts at varying intensities and durations.
    3. Take Actionable Strides From Journal Findings
    The great thing about the app is it gives you the chance to journal. In the morning, you’ll indicate if you consumed caffeine (how much and when), alcohol (how much), took prescription sleep medicine, viewed a screened device before falling asleep (how long), read a book, and shared your bed with a partner. If you find too much coffee late in the day keeps you up, scale back or cut yourself off at noon. If you find your smartphone or laptop is making it harder to fall asleep, nix the electronics an hour before bed. The WHOOP Strap 3.0 and app are less fixated on hitting arbitrary goals like getting in 10,000 steps, and more focused on interpreting empirical data. Make parallels. If you’re able to fall asleep faster when you listen to a meditation before bed, make it a nightly habit.
    4. Lean In to Heart Rate Variability
    When your HRV increases, indicating you’re more recovered, you can engage in more demanding sessions, which can be longer in duration or higher in intensity. Likewise, when HRV decreases, you can prioritize low-intensity sessions. Studies have shown this type of intuitive programming yields greater fitness gains than following a fixed program that doesn’t factor in your individual needs. This is where WHOOP outshines a personal trainer. Your coach might have a specific order of workouts for the week that might not be the most conducive to your fitness gains. However, WHOOP can help you fine-tune your training programs to prevent burnout via HRV. As gym culture drastically shifts, putting more of the onus into our hands, isn’t it time you take greater autonomy over your health and fitness? WHOOP thinks so—and we agree.
