Heat Illness

Our bodies create a tremendous amount of internal heat. We normally cool ourselves by sweating and radiating heat through our skin. Under certain circumstances, such as unusually high temperatures, high humidity, or vigorous exercise in hot weather, this natural cooling system may begin to fail, allowing internal heat to build up to dangerous levels. The result may be heat illness, which can come in the form of heat cramps, heat exhaustion, or heatstroke.Please be aware of the heat the next few days at camp!

Heat Cramps

Heat cramps are brief, severe cramps in the muscles of the legs, arms, or abdomen that may occur during or after vigorous exercise in extreme heat. The sweating that occurs with vigorous exercise causes the body to lose salts and fluids. And the low level of salts causes the muscles to cramp. Children are particularly susceptible to heat cramps when they haven’t been drinking enough fluids. Although painful, heat cramps aren’t serious.

What to Do:
Most heat cramps don’t require special treatment. A cool place, rest, and fluids should ease your child’s discomfort. Massaging cramped muscles may also help.

Heat Exhaustion
Heat exhaustion is a more severe heat illness that can occur when a person in a hot climate or environment hasn’t been drinking enough fluids. Symptoms may include:

  • Dehydration
  • Fatigue
  • Weakness
  • Clammy skin
  • Headache
  • Nausea and/or vomiting
  • Hyperventilation (rapid breathing)
  • Irritability

What to Do:

  • Bring the child indoors or into the shade.
  • Loosen or remove the child’s clothing.
  • Encourage the child to eat and drink.
  • Call the child’s doctor for further advice. If the child is too exhausted or ill to eat or drink, intravenous fluids may be necessary.

If left untreated, heat exhaustion may escalate into heatstroke, which can be fatal.

Heatstroke

The most severe form of heat illness, heatstroke is a life-threatening medical emergency. The body loses its ability to regulate its own temperature. Body temperature can soar to 106 degrees Fahrenheit (41.1 degrees Celsius) or even higher, leading to brain damage or even death if it isn’t quickly treated. Prompt medical treatment is required to bring the body temperature under control.

Factors that increase the risk for heatstroke include overdressing and extreme physical exertion in hot weather with inadequate fluid intake.

Heatstroke can also happen when a child is left in, or becomes accidentally trapped in, a car on a hot day. When the outside temperature is 93 degrees Fahrenheit (33.9 degrees Celsius), the temperature inside a car can reach 125 degrees Fahrenheit (51.7 degrees Celsius) in just 20 minutes, quickly raising a child’s body temperature to dangerous levels.

What to Do:

Call for emergency medical help if your child has been outside in the sun exercising for a long time and shows one or more of the following symptoms of heatstroke:

  • flushed, hot, dry skin with no sweating
  • Temperature of 105 degrees Fahrenheit (40.6 degrees Celsius) or higher
  • Severe, throbbing headache
  • Weakness, dizziness, or confusion
  • Sluggishness or fatigue
  • Seizure
  • decreased responsiveness
  • Loss of consciousness

While waiting for help:

  • Get the child indoors or into the shade.
  • Undress the child and sponge or douse him or her with cool water.
  • Do not give fluids.
