Be aware of the signs of heat stress

Heat stress occurs when the body is exposed to high temperatures and is unable to cool itself down. It affects concentration and reaction times, and can lead to serious complications such as heat stroke.


If you work in a hot environment, prevent heat stress by:


  • Drinking plenty of water to replace fluids lost through sweating
  • Taking regular "cool down" breaks
  • Using a cold washcloth, a water spray, or a fan to cool down
  • Wearing light-colored and lightweight clothing.


Be aware of the following symptoms:


  • Headache
  • Confusion
  • Dizziness
  • Weakness
  • Thirst
  • Nausea or vomiting


Recognizing the symptoms of heat stress is important, as delaying cooling down by a few minutes can cause serious complications


If you or one of your co-workers exhibits these symptoms, immediately seek medical assistance. Move to a cooler area, take off outer clothing, drink fluids, and apply cold water to your skin.
