Medically reviewed by Drugs. Last updated on May 18, The human body usually can regulate its temperature. When the body gets too hot, it uses several strategies to cool down, including sweating. But if a person spends too much time in the heat without taking in enough fluids, the body's cooling processes can't work properly. When the body becomes dehydrated, it can no longer cool itself by sweating. When this happens, body temperature can rise high enough to make the person sick.
The first symptoms of heat illness occur as the body temperature climbs above normal, and can include headache, nausea, vomiting, muscle cramps and fatigue. These early symptoms sometimes are called heat exhaustion. If steps are not taken to reduce body temperature, heat exhaustion can worsen and become heat stroke. Heat stroke is a serious, potentially life-threatening form of heat illness.
The body temperature rises to degrees Fahrenheit or higher and you develop neurological changes, such as mental confusion or unconsciousness.
At these high temperatures, body proteins and the membranes around the cells in the body, especially in the brain, begin to be destroyed or malfunction. The extreme heat can affect internal organs, causing breakdown of the heart muscle cells and blood vessels, damage to internal organs, and death.
There are two main ca uses of heat stroke:. A doctor will examine the person and do tests to check for other possible causes of the high temperature. Tests may include a computed tomography CT scan of the head, blood tests and a lumbar puncture spinal tap.
The doctor also will do urine and blood tests to monitor how well the kidneys are functioning. Dehydration and heat stroke can be a major stress for the kidneys. It is standard for a person with heat stroke to stay in the hospital for one or more days so that any complications can be identified quickly.
Complete recovery from heat stroke and its effects on body organs may take two months to a year. Most cases of heat stroke can be prevented.

This can be done by removing tight or unnecessary clothing, spraying the person with water, blowing cool air on the person, or wrapping the person loosely in wet sheets.
Alternatively, ice packs can be placed at the neck, groin and armpits to accelerate cooling. If these methods do not lower body temperature enough, a doctor may try to lower temperature from the inside by flushing the stomach or rectum with cold water. Severe cases may require cardiopulmonary bypass, in which the person's blood is diverted from the heart and lungs into a collection machine, cooled, and then returned to the body.
In some cases, anti-seizure or muscle-relaxing medications may be given to control convulsions and shivering. Aspirin and acetaminophen Tylenol do not help lower body temperature when a person has heat stroke, and these medications should be avoided if heat stroke is suspected.
People with heat stroke generally need to be hospitalized so they can be tested for complications that may appear after the first day. One common complication is muscle breakdown caused by the heat. In this condition, called rhabdomyolysis, byproducts of the muscle breakdown appear in the bloodstream and can damage the kidneys.
