Heat exhaustion

Heat exhaustion is a heat-related illness caused by overheating of the body.

Heat exhaustion is one of the three heat-related illness, which include heat cramps (the mildest) and heat stroke (the most severe).

Symptoms of heat exhaustion include:

  • Heavy sweating
  • Cool, moist skin with goose bumps when in the heat
  • Weak or rapid pulse
  • Dizziness
  • Faintness/li>
  • Fatigue
  • Nausea
  • Headache

Be aware that heat these symptoms may develop over time or suddenly and in no particular order. If you suspect someone is experiencing heat exhaustion, then stop all activity and rest. Move the person to a cooler place, and drink cool water or sports drinks (no energy drinks).

Heat exhaustion is preventable. When the temperature is high, you may try:

  • Wear loose fitting, and light colored clothing
  • Drink plenty of fluids
  • Wear sunscreen with at least SPF 30
  • Look for cooler places and not hot spots

Heat exhaustion can progress to a heat stroke (life threatening) without proper intervention. Contact your doctor if symptoms worse or do not improve over an hour. Call 911 immediately, if your body temperature reaches 104 F (40 C) or higher.

Heat Stroke

Heat stroke is a heat-related illness from prolonged or intense exposure to high temperatures. This results from your body gaining heat faster than it can cool itself down, which leads to failure of the body’s temperature control system.

Heat stroke is the most serious of the three heat-related illnesses. It often occurs from a progression from milder heat-related illness such as heat cramps and heat exhaustion.

Symptoms of heat stroke include:

  • Nausea
  • Seizures
  • Confusion
  • Disorientation
  • Loss of consciousness or coma

Heat stroke is the most serious form of heat-related illnesses and considered a life-threatening medical emergency because it can kill or damage the brain and other internal organs. If you suspect that some one has heat stroke, call 911 immediately and give first aid until paramedics arrive.
