These syndromes vary in seriousness, ranging from mild to possibly life-threatening. Other types of heat-related illnesses include heat rash, heat cramps, heat syncope and heatstroke.<\/p>\n<p>Heat exhaustion can happen when the body loses too much water or salt &mdash; usually because of heavy sweating or dehydration.  It can begin suddenly or happen over time, usually after working, exercising or playing in the heat.<\/p>\n<p>Call 911 or your local emergency number if the affected person:<\/p>\n<ul>\n<li>Faints.<\/li>\n<li>Becomes agitated.<\/li>\n<li>Is confused.<\/li>\n<li>Has a seizure.<\/li>\n<li>Is not able to drink.<\/li>\n<li>Has a core body temperature &ndash; measured with a rectal thermometer &ndash; of 104 degrees Fahrenheit (40 degrees Celsius), which indicates heatstroke.<\/li>\n<\/ul>\n<p>Heat exhaustion symptoms include:<\/p>\n<ul>\n<li>Cool, moist skin with goose bumps when in the heat.<\/li>\n<li>Heavy sweating.<\/li>\n<li>Faintness.<\/li>\n<li>Dizziness.<\/li>\n<li>Fatigue.<\/li>\n<li>Weak, rapid pulse.<\/li>\n<li>Low blood pressure after standing up.<\/li>\n<li>Muscle cramps.<\/li>\n<li>Nausea or vomiting.<\/li>\n<li>Headache.<\/li>\n<li>Extreme thirst.<\/li>\n<li>Mild confusion.<\/li>\n<li>Decreased urine output.<\/li>\n<\/ul>\n<p>Untreated, heat exhaustion can lead to heatstroke, which is a life-threatening condition. If you suspect heat exhaustion, take these steps immediately:<\/p>\n<ul>\n<li>Move the person out of the heat and into a shady or air-conditioned place.<\/li>\n<li>Lay the person down and raise the legs and feet slightly.<\/li>\n<li>Remove tight or heavy clothing.<\/li>\n<li>Have the person sip chilled water, a sports drink containing electrolytes or another nonalcoholic beverage without caffeine.<\/li>\n<li>Cool the person by spraying or sponging with cool water and fanning.<\/li>\n<li>Monitor the person carefully.<\/li>\n<\/ul>\n<p>Contact a healthcare professional if symptoms get worse or if the person doesn&#8217;t improve after taking first-aid measures.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>How to recognize and provide first-aid treatment for heat exhaustion.<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","template":"","tags":[1729,1687,1682,1684],"class_list":["post-52545","mayo","type-mayo","status-publish","hentry","tag-health-category","tag-medical-procedure","tag-person-group-concept","tag-theme-of-focus","content_type-first-aid"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 -
