Exposure to excessive heat, causing loss of fluids and a rise in body temperature. This may occur at any age but most common in babies and elderly people. Prolonged exposure to high atmospheric temperature. Brief exposure to very high atmospheric temperature. (direct exposure to sun is not necessary). Heavy manual work in high temperature, high humidity. Pre-existing chronic diseases and alcoholism are some of the predisposing factors.
In a hot environment, the body loses heat by diverting blood to the skin and by sweating. Profuse sweating may lead to an excessive loss of fluids and salts, resulting in heat exhaustion. This condition is rarely serious ,but, if exposure to heat continues, heat stroke may occur as the body normal cooling mechanisms break down and the temperature of the body rises. Heat stroke is a life-threatening medical emergency.
Heat exhaustion and heat stroke most commonly occur above 104 degree F (40 degree C).High humidity increases because sweating is ineffective and heat loss is decreased.
Who is at risk ?
Heat exhaustion and heat stroke may affect otherwise healthy people, particularly after physical exertion in a hot climate. People who come from temperate climates and travel to the tropics need time to acclimatize to the heat before they can safely exert themselves.
The body’s cooling mechanisms are less efficient in babies and elderly People, making them more susceptible to heat exhaustion and heat stroke. Obesity, diabetes mellitus, alcohol dependence, and chronic heart failure all decrease the body’s ability to lose heat. Diarrhoea may contribute to dehydration and increase the risk of development heat exhaustion and heat stroke.
What are the symptoms?
After prolonged exposure to hot conditions, the following symptoms of heat – exhaustion may develop:
1. Profuse Sweating
3. Muscle cramps
4. Nausea and vomiting
5. Faintness and unsteadiness
If exposure to heat continues, the body temperature rises and heatstroke may develop, causing symptoms such as:
1.Fast, shallow breathing.
2.Confusion and disorientation
Left untreated, heat stroke may progress to coma in minutes .Death may be due to kidney failure, acute heart failure, or direct heat –induced damage to the brain.
What can i do it ?
Heat exhaustion can be treated easily. The affected person should rest in a cool place, ideally in an air- conditioned building, and sip cool, salty drinks until he or she feels comfortable. If heat stroke is suspected, he or she should be admitted to the hospital as soon as possible.
What might the doctor do ?
Once in the hospital, an examination is done, and blood tests are carried out to assess the level of salts in the blood.
Treatment of heat stroke is usually carried out in a critical care unit. The body temperature is lowed by sponging the body with tepid water or loosely wrapping the person in a wet sheet and placing him or her near a fan. Intravenous fluids are given. Once the body temperature has been reduced to 100 degree F(38 degree), These cooling procedures are stopped to prevent hypothermia (below) from developing. Monitoring is still carried out continuously to make sure that the body temperature returns to normal level and that the vital organs are functioning normally. In some severe cases, mechanical ventilation may be required to help breathing.
Most people with heat exhaustion recover in a few hours if they are moved to a cooler place and fluids are gradually replaced. If heat stroke is treated promptly, most people usually recover after a few days of bed rest, although their body temperature may fluctuate for several weeks after ward.
Can they be prevented?
