Heatstroke

From WikiMD's Wellness Encyclopedia

Heatstroke is a severe form of hyperthermia that occurs when the body is unable to regulate its temperature. The body's temperature rises rapidly, the sweating mechanism fails, and the body is unable to cool down. Heatstroke can cause death or permanent disability if emergency treatment is not provided.

Signs and Symptoms[edit | edit source]

Heatstroke symptoms can vary, but may include:

  • An extremely high body temperature (above 103°F)
  • Red, hot, and dry skin (no sweating)
  • Rapid, strong pulse
  • Throbbing headache
  • Dizziness
  • Nausea
  • Confusion
  • Unconsciousness

Causes[edit | edit source]

Heatstroke can occur as a result of:

  • Prolonged exposure to a hot environment
  • Strenuous activity
  • Wearing excess clothing
  • Drinking alcohol
  • Dehydration
  • Certain health conditions, such as heart, lung, or kidney disease

Prevention[edit | edit source]

Prevention strategies include:

  • Drinking plenty of fluids
  • Wearing lightweight, light-colored, loose-fitting clothing
  • Protecting against sunburn
  • Taking it easy during the hottest parts of the day
  • Never leaving anyone in a parked car

Treatment[edit | edit source]

Treatment involves reducing the body's temperature as quickly as possible. This may involve:

  • Moving the person to a cooler environment
  • Removing excess clothing
  • Cooling the person with whatever means available, such as a cool bath or damp sheets
