The Effects Of Extreme Heat

The Effects Of Extreme Heat

Being in too much hot environment can have some negative effects on our body. If the negative effects of the heat are not intervened quickly, this can become vital.

Heat Exhaustion

Hot exhaustion occurs due to prolonged exposure to excessive heat and loss of water and minerals due to not taking enough liquid. Generally, it is not very serious, but the first aid is done quickly and you feel better when the body temperature is lowered. However, uncontrolled temperature exhaustion may return to heat stroke. In this case, it must be treated immediately.


  • Excessive sweating
  • Fatigue, weakness
  • Fainting feeling
  • Acceleration of pulse
  • Rise of fever

Heat Stroke

Heat stroke is very serious and can be fatal. It occurs when the body’s thermal regulating mechanism no longer functions; consequently, the body’s temperature increases to a very dangerous level. The person feels ill and has a high temperature.

Several symptoms can indicate an attack of heat stroke:

  • Serious neurological disorders (loss of consciousness, convulsions…)
  • Cardiovascular difficulties
  • Skin reactions (burning sensation in the skin
  • Dry throat and tongue)
  • Digestive trouble (nausea, vomiting and diarrhoea).

Heat stroke traditionally occurs without exerting any physical effort – during a summer heat wave or in situations that are abnormally hot. It usually affects either very young children or elderly adults. It must be distinguished from physically-induced hyperthermia, which often affects marathon runners or military personnel who have demonstrated intense and prolonged physical effort in hot, humid conditions. Heat stroke indications are irregular, and can include cramps or other anomalies after being exposed for long periods to very high temperatures. Usually, heat stroke can be treated successfully but it requires fast emergency medical care. The victim must be cooled down and rehydrated immediately. Get the victim in the shade, give him/her cold drinks, remove their clothing and cover them in a wet sheet. Fan them frequently and contact the fire department or the ambulance company immediately.

Beware Of The Sun

We all need the sun to live. It contributes to our psychological well-being (acts as an anti-depressant), has a positive effect on certain skin diseases, and stimulates the production of Vitamin D, which is essential for children’s growth and strong, healthy bones. The sun’s rays can be broken down into visible rays (sunlight), infrared rays (which cause heat sensations) and ultra-violet rays (UV). UV rays, which are invisible and give off no heat, are partially filtered by the ozone layer in the atmosphere. To defend itself, the skin increases the production of melanin, a pigment whose abundance in people from extremely sunny countries effectively protects them from the ill effects of the sun.

However, to overly expose oneself to the sun, even if you have naturally pigmented skin, is to run a high risk. There is only one golden rule – to have fun in the sun, you must protect your skin! Remember to take quick action against the effects of heat!
