Being unaccustomed to the heat, such as moving from a cooler climate to a warmer climate.

Sleep deprivation, which can decrease the rate of sweating.

Being overweight, which causes the body to generate more heat and reduces the body's ability to cool down.

Wearing bulky or heavy clothing, such as firefighting gear, in the heat.

Dehydration from not drinking enough water.High heat in the surrounding environment, without vigorous activity, can be enough to cause heat stroke in these people.įactors that can contribute to heat stroke include: Non-exertional heat stroke tends to occur in people who have a diminished ability to regulate body temperature, such as older people, very young children or people with chronic illnesses.Because of the lack of concern, early symptoms may be dismissed or ignored. It typically strikes young, otherwise healthy people, those least likely to be concerned about the effects of heat on their health. Exertional heat stroke occurs when someone is vigorously active in a hot environment, such as playing sports on a hot summer day or participating in military training activities.There are two main ca uses of heat stroke: The extreme heat can affect internal organs, causing breakdown of the heart muscle cells and blood vessels, damage to internal organs, and death. 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 body temperature rises to 105 degrees Fahrenheit or higher and you develop neurological changes, such as mental confusion or unconsciousness. Heat stroke is a serious, potentially life-threatening form of heat illness. If steps are not taken to reduce body temperature, heat exhaustion can worsen and become heat stroke. These early symptoms sometimes are called heat exhaustion. The first symptoms of heat illness occur as the body temperature climbs above normal, and can include headache, nausea, vomiting, muscle cramps and fatigue. When this happens, body temperature can rise high enough to make the person sick. When the body becomes dehydrated, it can no longer cool itself by 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 gets too hot, it uses several strategies to cool down, including sweating. The human body usually can regulate its temperature.
