Heat exhaustion symptoms can include heavy sweating, rapid pulse or heart rate, clammy or pale skin, nausea, fatigue, headache or lightheadedness, and even fainting. If you're experiencing the symptoms of heat exhaustion, you should cool yourself down, get into the shade or air conditioning, and drink lots of water. To prevent heat exhaustion – and more dangerous heat illness like heatstroke – it's important to avoid exercise in the hottest parts of the day and stay hydrated when it's hot and humid. Heat exhaustion is a condition caused by extreme heat, and its symptoms include heavy sweating and a rapid pulse. But most often, heat exhaustion occurs when people exercise or work outdoors in hot or humid conditions.
"Your body temperature can increase about a degree for every five minutes of exercise you're doing," says Joshua Scott, MD, primary care sports medicine physician at Cedars-Sinai Kerlin-Jobe Institute. When it's hot outside, it's important to know how to prevent heat exhaustion, and treat any symptoms by cooling yourself down immediately. Without treatment, heat exhaustion can develop into heatstroke, a more dangerous heat-related illness. Here's what you need to know to keep yourself safe and avoid heat-related illness. To treat symptoms of heat exhaustion, it's important to cool yourself down immediately.
Heat exhaustion can happen to anyone, but those most at risk include children under four and people over age 65. In addition, those who are newer to exercise – or have taken a long break from working out – are also at risk because their body won't be as accustomed to regulating temperature during physical activity. Exercising in a hot, humid environment can also increase your risk for heat exhaustion. If you live somewhere like Florida or South Carolina where relative humidity levels can reach 60% to 80%, the sweat on your skin won't evaporate as much, and your body won't be able to cool itself as effectively. Some medications, like antihistamines used to treat allergies or diuretics used to treat high blood pressure, may also affect your body's ability to sweat effectively or stay hydrated, and can predispose you to heat exhaustion, Scott says. Talk with your doctor if you're worried that your medication may be causing heavy sweating, rapid pulse, lightheadedness, or nausea during high temperatures. When you're in hot and humid conditions, Scott recommends taking a 10-minute break for every 40 minutes of exercise. You usually don't feel thirsty until you're already dehydrated, Scott says, so it's important to drink water throughout the day, and especially when you're working out. caption It's important to know the symptoms of heatstroke if you'll be outside in extreme heat. Heatstroke symptoms can include a core body temperature above 104 degrees Fahrenheit, mental confusion or slurred speech, flushed skin, rapid breathing and heart rate, and even unconsciousness. To prevent heatstroke, it's important to stay cool, drink lots of water, and avoid exercise in the hottest parts of the day during the summer months. Heatstroke can occur when your core body temperature reaches 104 degrees Fahrenheit or higher, and your body is unable to cool itself down. Before someone experiences heatstroke, they will feel symptoms of heat exhaustion, such as heavy sweating and a rapid pulse. This often occurs when you're outside during hot and humid temperatures, and especially if you're working or exercising at that time. If heat exhaustion escalates to heatstroke, here's how you can recognize the symptoms, and how to treat them. Along with a body temperature above 104 degrees Fahrenheit, the major signs of heatstroke include:. When body temperature gets above 104 degrees Fahrenheit, proteins in the brain can start to break down, which can trigger changes in mental status. While heat exhaustion can be treated at home by cooling yourself down, heatstroke always requires immediate medical treatment because it can cause brain damage, organ failure, and even death if not promptly treated. If you are with someone who you think may be experiencing heatstroke, you should try to cool them down before they get to the hospital to slow down the potential destruction of organs, Scott says. To prevent heat-related illnesses, it's always best to refrain from extended physical activity during the hottest parts of the day, between 3 p.m. and 4:30 p.m. If you have to be outside in hot and humid conditions, it's vital to stay hydrated and take frequent resting breaks. If you notice symptoms of heat exhaustion, like heavy sweating, rapid pulse, fatigue, nausea, lightheadedness, or weakness, take them seriously and cool yourself down by: A child's body can heat up three to five times faster than an adult's, so it's especially important to watch for signs of heat exhaustion in children.
