Estevan and area is under a heat warning once again, putting people at risk, especially the very young, elderly and those who work outside.

Heat exhaustion and heat stroke are real concerns on a day like today. Medical Health Officer with the Saskatchewan Health Authority Dr Landre Medu said symptoms to watch out for include dizziness, confusion, fatigue, and nausea.

"In heat exhaustion, you also tend to see the individual also continues to sweat. Heat stroke, on the other hand, the body temperature exceeds about 40 degrees Celsius. There is some alteration in the mental health of the individual so that person may be in a coma, may be experiencing some delirium or hallucinations. Persons who are experiencing heat stroke, their blood pressure tends to be low. In heat exhaustion it's still normal," explained Medu.

Dr Medu said a classic symptom of heat stroke is when the skin of the individual is dry because they have quit sweating. He said if a person experiences the symptoms of heat stroke they should seek immediate medical attention.

Dr Medu said it is best to prevent these issues by keeping out of the sun, wearing loose-fitting and light clothing, staying hydrated and avoiding physical exertion. He said it's best to avoid alcohol and caffeine, which tend to dehydrate people, drink plenty of cold water and take cool showers to cool off.

Medu also suggests checking on home-bound family and neighbours to ensure they are hydrated and not overheating.
