Symptoms of heat stroke embody lack of consciousness, confusion, slurred speech, profuse sweating, sizzling or dry pores and skin or seizures. In these instances, it can be crucial to search assist by calling 911 and to work to cool the physique shortly with chilly moist cloths or ice tub. If doable, transfer the individual to a cool, shaded space, take away any outer clothes and flow into the air round them.
Symptoms are particularly essential to look ahead to when exercising outside or competing in athletic occasions, notably for younger folks. It’s estimated that about 9,000 high school athletes within the United States are handled for heat-related sicknesses every year. And elite athletes aren’t exempt from the results of heat: Research on the Tokyo 2020 Olympic and Paralympic Summer Games discovered that about 1 in 100 Olympic athletes developed heat-related sickness.
During excessive heat

Even folks making an attempt extra typical out of doors actions or exercise can face comparable dangers and a well-recognized dilemma: Push via the heat 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 can assist you practice extra comfortably and safely, mentioned Dr. Kent Bradley, an Arizona-based preventive drugs doctor and the chief medical government of the health and precision drugs firm 10X Health.
During summer 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 mentioned.
Therefore, what you eat and drink and when you exercise can play a task in your exercises and your total well being, he mentioned, particularly throughout excessive summer temperatures.
What you eat can assist make sizzling summer days really feel simpler, particularly when you’re making an attempt to keep on with common exercise.
Before a exercise, give attention to simply digested carbohydrates that present fast power with out sitting closely within the abdomen, and attain for hydrating meals, Bradley mentioned.
“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 mentioned. “A smoothie also would be OK. Or a frozen banana, and you could add a bit of protein with a nut butter.”
Carbohydrates, resembling recent fruits like bananas or berries, are essential for supporting exercise as a result of they supply the physique with gasoline earlier than moderate- and high-intensity exercises. This can assist delay fatigue and preserve stamina.
For fueling a summer 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, an authorized energy and conditioning specialist and mind-body coach in skilled sports activities and NCS Health contributor, mentioned 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 mentioned.
For exercises lasting longer than an hour, particularly in sizzling circumstances, sports activities diet consultants suggest consuming about 30 to 60 grams of carbohydrates per hour of exercise, mentioned Dr. Colby Genrich, sports activities drugs 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 mentioned.
Heavy, high-fat meals instantly earlier than exercise can enhance your digestive workload and contribute to emotions of sluggishness within the heat. Therefore, the way you time your meals – earlier than and after exercise – is essential, mentioned 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 an alternative of three massive meals. Aim for about “an hour and a half or two hours between your eating opportunities,” Benardot mentioned.
After exercise, “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 mentioned. “They should really start recovering within 15 minutes of getting off the field.”
Recovery diet turns into particularly essential after coaching in sizzling climate. For post-workout meals, sports activities nutritionists and physicians suggest combining carbohydrates and protein to replenish glycogen shops and assist muscle restore. Glycogen is the saved type of glucose within the physique, a principal supply of power that the physique shops primarily within the liver and muscle tissue. Carbohydrates in meals are used to kind glucose and glycogen.
“After exercise, especially in the heat, athletes should focus on the three Rs: rehydrate, refuel and repair,” Genrich mentioned.
“Recent research supports consuming 20 to 30 grams of protein within the first few hours after exercise combined with a form of carbohydrate,” he mentioned. “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 exercise, hydrating the physique is equally essential and “don’t wait until you’re thirsty to start drinking,” Genrich mentioned.
Drinking sufficient water stays essential for everybody, and for many exercises lasting lower than an hour, water is ample. 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 mentioned. “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 classes, watermelon, oranges, berries, cucumbers or different water-rich fruits and greens additionally can assist 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 mentioned. “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 notice that hydration begins earlier than your exercise, too – and for summer exercises, that might be the evening earlier than a exercise.
“And make sure that you’re not drinking too much caffeine the morning of a workout,” Genrich mentioned. “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 would possibly want extra hydration all through the day. A easy hydration test can occur whereas utilizing the lavatory: Urine showing pale yellow is an indication that you simply are extra hydrated, whereas dark amber urine generally is a signal of dehydration.
It’s additionally essential to select your exercise window correctly, particularly when having fun with the outside within the summer.
The most secure and simplest occasions for out of doors exercise are typically early morning, earlier than 9 a.m., or after the solar begins to set. These are occasions 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 mentioned.
Midday exercises expose athletes to the very best heat load and can dramatically enhance the danger of heat exhaustion, he mentioned. Humidity compounds the issue as a result of sweat evaporates much less effectively, making it more durable for the physique to cool itself.
“Early morning is generally ideal because temperatures tend to be at their lowest,” Santas mentioned. “If morning isn’t possible, later in the evening after sunset is your next best option.”
