See medical attention if symptoms worsen or last longer than one hour. If heat exhaustion is untreated, it may progress to heat stroke. The pulse rate will be fast and weak, and breathing will be fast and shallow. The warning signs of heat exhaustion include the following: What are the warning signs of heat exhaustion? Those most prone to heat exhaustion are elderly people, those with high blood pressure, and those working or exercising in a hot environment. Heat exhaustion is a milder form of heat-related illness that can develop after several days of exposure to high temperatures and inadequate or unbalanced replacement of fluids. Get medical assistance as soon as possible.Do not give the victim alcohol to drink.If emergency medical personnel are delayed, call the hospital emergency room for further instructions.Monitor body temperature and continue cooling efforts until the body temperature drops to 101-102☏.For example, immerse the victim in a tub of cool water place the person in a cool shower spray the victim with cool water from a garden hose sponge the person with cool water or if the humidity is low, wrap the victim in a cool, wet sheet and fan him or her vigorously. Cool the victim rapidly, using whatever methods you can.Have someone call for immediate medical assistance while you begin cooling the victim. If you see any of these signs, you may be dealing with a life-threatening emergency. What should I do if I see someone with any of the warning signs of heat stroke? An extremely high body temperature (above 103☏).Warning signs of heat stroke vary but may include the following: What are the warning signs of a heat stroke? Heat stroke can cause death or permanent disability if emergency treatment is not provided. Body temperature may rise to 106☏ or higher within 10 to 15 minutes. It occurs when the body becomes unable to control its temperature: the body’s temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down. Heat stroke is the most serious heat-related illness. Those at greatest risk for heat-related illness include infants and children up to four years of age, people 65 years of age and older, people who are overweight, and people who are ill or on certain medications. Who is at greatest risk for heat-related illness?

Other conditions that can limit the ability to regulate temperature include old age, youth (age 0-4), obesity, fever, dehydration, heart disease, mental illness, poor circulation, sunburn, and prescription drug use and alcohol use.

When the humidity is high, sweat will not evaporate as quickly, preventing the body from releasing heat quickly. Several factors affect the body’s ability to cool itself during extremely hot weather. Very high body temperatures may damage the brain or other vital organs. In such cases, a person’s body temperature rises rapidly. But under some conditions, sweating just isn’t enough. The body normally cools itself by sweating. World Health Organization: “The known health effects of UV.People suffer heat-related illness when the body’s temperature control system is overloaded.
