Heat Exhaustion occurs when the body is not able to sweat enough to cool itself. Symptoms of heat exhaustion include:
- Dizziness, weakness, nausea, headache, and vomiting
- Blurry vision
- Body temperature 38.3 C
- Sweaty skin
- Feeling hot and thirsty
- Having difficulty speaking
When someone is suffering from heat exhaustion, he/she should move into a cooler place and drink plenty of water immediately.
Heat Stroke is the result of untreated heat exhaustion and includes the following symptoms:
- Unawareness of heat and thirst
- Body temperature rises rapidly above 38.3 C
- Confusion or delirium
- Loss of consciousness
When someone is suffering from heat stroke, medical personnel should be called immediately, as the condition is life-threatening. Place ice packs on the person’s armpits and groin until help arrives.
To avoid heat illnesses in summer temperatures, remember to drink lots of water – even if you are not thirsty. Additionally, wear light-coloured lightweight clothing made of natural fibres and put on a well-ventilated hat. Lastly, avoid leaving air-conditioned areas in the middle of the day if you can. Instead, get things done outside in the early morning or evening when temperatures are cooler.
