And elite athletes aren’t exempt from the consequences of warmth: Research on the Tokyo 2020 Olympic and Paralympic Summer Games discovered that about 1 in 100 Olympic athletes developed heat-related sickness.
During excessive warmth

Even folks attempting extra typical out of doors actions or train can face comparable dangers and a well-recognized dilemma: Push by the warmth or retreat indoors?
For individuals who could select to enterprise out, issues like exercising throughout cooler elements of the day, prioritizing hydration earlier than thirst strikes, fueling with carbohydrates and replenishing fluids and electrolytes after exercises may help you prepare extra comfortably and safely, stated Dr. Kent Bradley, an Arizona-based preventive medication doctor and the chief medical government of the health and precision medication firm 10X Health.
During summer season months, “a couple of things is to recognize that the body is going to be depleted of not just hydration of water when we sweat, but electrolytes, and we’re going to be losing sugar as well,” Bradley stated.
Therefore, what you eat and drink and whenever you train can play a job in your exercises and your general well being, he stated, particularly throughout excessive summer season temperatures.
What you eat may help make sizzling summer season days really feel simpler, particularly whenever you’re attempting to stay with common train.
Before a exercise, concentrate on simply digested carbohydrates that present fast vitality with out sitting closely within the abdomen, and attain for hydrating meals, Bradley stated.
“Consider something much more light, maybe something that has a lot of water content to begin with, like watermelon, and maybe add some sea salt,” he stated. “A smoothie also would be OK. Or a frozen banana, and you could add a bit of protein with a nut butter.”
Carbohydrates, corresponding to contemporary fruits like bananas or berries, are necessary for supporting train as a result of they supply the physique with gasoline earlier than moderate- and high-intensity exercises. This may help delay fatigue and keep stamina.
For fueling a summer season exercise, “I am a big fan of overnight oats with a little fruit and nuts or nut butter for a bit of protein. You could also do a hard-boiled egg with a rice cake and fruit,” Dana Santas, a licensed energy and conditioning specialist and mind-body coach in skilled sports activities and CNN Health contributor, stated in an e mail.
“Also, because sodium helps your body retain fluid and delays dehydration, be sure to add a pinch of salt to your oatmeal or egg,” Santas stated.
For exercises lasting longer than an hour, particularly in sizzling circumstances, sports activities vitamin specialists advocate consuming about 30 to 60 grams of carbohydrates per hour of exercise, stated Dr. Colby Genrich, sports activities medication doctor at Texas Tech Physicians of El Paso, who works with skilled soccer gamers within the El Paso space.
But “try to limit dairy and high-fiber foods before exercise in order to avoid some of the gastrointestinal stomach issues,” Genrich stated.
Heavy, high-fat meals instantly earlier than train can enhance your digestive workload and contribute to emotions of sluggishness within the warmth. Therefore, the way you time your meals – earlier than and after train – is necessary, stated Dr. Dan Benardot, a professor at Emory University and a registered dietitian who has been the nutritionist for a number of Team USA athletes.
He recommends consuming a number of small meals all through the day as a substitute of three massive meals. Aim for about “an hour and a half or two hours between your eating opportunities,” Benardot stated.
After train, “a lot of athletes, they finish their activity, they go into the locker room, they shower, they change their clothes and they go have a group meal with people, but that’s maybe an hour and a half or two hours after they finish the activity,” he stated. “They should really start recovering within 15 minutes of getting off the field.”
Recovery vitamin turns into particularly necessary after coaching in sizzling climate. For post-workout meals, sports activities nutritionists and physicians advocate combining carbohydrates and protein to replenish glycogen shops and assist muscle restore. Glycogen is the saved type of glucose within the physique, a foremost supply of vitality that the physique shops primarily within the liver and muscular tissues. Carbohydrates in meals are used to type glucose and glycogen.
“After exercise, especially in the heat, athletes should focus on the three Rs: rehydrate, refuel and repair,” Genrich stated.
“Recent research supports consuming 20 to 30 grams of protein within the first few hours after exercise combined with a form of carbohydrate,” he stated. “On the protein front, where you’re rebuilding the muscles, eat something that has 20 to 30 grams of protein – that can be peanut butter, yogurt or cottage cheese, or a protein smoothie – and then balancing that with some carbohydrate as well, so maybe a turkey sandwich with some wheat bread in order to replenish those carbohydrate stores.”
After train, hydrating the physique is equally important and “don’t wait until you’re thirsty to start drinking,” Genrich stated.
Drinking sufficient water stays necessary for everybody, and for many exercises lasting lower than an hour, water is adequate. But there are some instances during which adding electrolytes could also be useful.
“For longer or more intense workouts, especially those lasting over an hour, fluids containing electrolytes may be beneficial,” Genrich stated. “Below an hour, it’s not completely necessary to replenish all those electrolytes. You’re probably not losing enough to have to replenish during the activity, but activities over an hour, you want to replenish.”
After longer exercise periods, watermelon, oranges, berries, cucumbers or different water-rich vegatables and fruits additionally may help hydrate.
“Sometimes people confuse feelings of dehydration with hunger. After a summer workout your fluid and electrolyte status is a priority,” Santas wrote.
“Replacing what you lost in your sweat is foundational to everything else your body needs to recover, including muscle repair and glycogen replenishment,” she stated. “A protein shake made with fruit and a liquid base like coconut water is a great option — it covers your protein needs, gives you fast-digesting carbs and the coconut water provides additional electrolytes to support rehydration.”
Many folks could not understand that hydration begins earlier than your train, too – and for summer season exercises, that could possibly be the evening earlier than a exercise.
“And make sure that you’re not drinking too much caffeine the morning of a workout,” Genrich stated. “One or two cups of coffee is fine, but beyond that, caffeine can cause a lot of dehydration.”
There are methods to search for cues that you simply may want extra hydration all through the day. A easy hydration examine can occur whereas utilizing the lavatory: Urine showing pale yellow is an indication that you’re extra hydrated, whereas dark amber urine is usually a signal of dehydration.
It’s additionally necessary to decide on your exercise window correctly, particularly when having fun with the outside in the summertime.
The most secure and only instances for out of doors exercise are usually early morning, earlier than 9 a.m., or after the solar begins to set. These are instances when air temperatures, pavement temperatures and photo voltaic radiation are considerably decrease.
“I’d stay away from that 9 a.m. to 4 p.m. window – and definitely that peak window of 11 a.m. to 3 p.m. – that’s when it’s the hottest,” Bradley stated.
Midday exercises expose athletes to the best warmth load and might dramatically enhance the danger of warmth exhaustion, he stated. Humidity compounds the issue as a result of sweat evaporates much less effectively, making it tougher for the physique to chill itself.
“Early morning is generally ideal because temperatures tend to be at their lowest,” Santas stated. “If morning isn’t possible, later in the evening after sunset is your next best option.”
