Normally, healthy human body's temperature is around 36-37°C and it will be the same in any weather condition, both cold or hot weather condition. "In hot weather or during vigorous activity, the body perspires. As this perspiration evaporates from the skin, the body is cooled" (The Health Central Network, 2009). However, if our bodies are exposured too long under the sun light, our bodies' temperature system may lose its functions and may make our body temperature unstable and uncontrolled. This is called hyperthermia but also known as heatstroke and sunstroke. In this condition, our infected bodies will produce and absorb more heat than it should to. However, hyperthermia is one of homeostasis diseases because it attacks our bodies' temperature system or hypothalamus.

People who get hyperthermia may experience:

  • Body temperature increases to more than 40ºC.
  • Headache and pale
  • Fainting or dizziness
  • Blood pressure will drop because of dehydration
  • The skin will become red
  • Not be able to produce sweat

First Aid:

  • The victim needs medical emergency and maybe he or she should be hospitalized or,
  • The victim should be moved to cooler place, stay away from heat.
  • The victim's clothes should be remove to promote heat loss.
  • Cool down the victim's body by wrapping the victim on wet towel or clothes.
  • Compresses the victim.
  • The victim should drink lot of water to avoid dehydration.


How to prevent hyperthermia?

Hyperthermia can be prevented by avoiding overheating and dehydration. Perhaps you want to go out to hot places, you can use vent or hat to avoid sun heat. Then, try to avoid exercising during daylight hours in hot weather. In addition, in hot weather you have to drink lot of fluid such as water to replace the fluid in your body from sweating.
