Heat Stroke Can Be Dangerous
The hot temperatures of summer remind health care providers of the
increasing number of people who may suffer from heat stroke. Adequate
hydration, defined as at least eight to twelve cups of water per day, is one
way to prevent heat stroke. People with an increased risk of experiencing
this heat-related problem include those at an older age, those who are
obese, and people who were born with an impaired ability to sweat. Dehydration,
alcohol use, cardiovascular disease, and some medications
may also increase the risk of heat stroke.
When heat stroke occurs the body loses the ability to manage the
excess heat, which is accomplished under normal conditions through
temperature control and sweating. A dramatically elevated body temperature
(greater than 104°F) accompanied by mental status changes are signs
of heat stroke. Skin may be hot and dry, or moist when exertion is the
cause. Rapid heartbeat, rapid and shallow breathing, elevated or lowered
blood pressure, and sweating cessation are all physical signs of heat
stroke. If heat stroke is suspected, immediately contact medical emergency
assistance.
