AMA WA vice-president Richard Choong said heat exhaustion was a dangerous medical condition and could impact on a person quickly.

Mr Choong said extreme hot temperature reduced the human body’s ability to cool itself through sweating, which could lead to excessive overheating.

“It is sometimes said that heat exhaustion is a silent killer so it is important to remain aware of the impact of high temperatures, especially on the young and elderly,” he said.

Heat and humidity were responsible for more deaths than any other weather conditions.

Symptoms of heat exhaustion include increased heart rate, vomiting, dizziness, confusion, headaches, nausea and cramps.

“Anyone experiencing these symptoms should take quick action to cool down, drink water and to seek medical attention if their condition does not improve,” Dr Choong said.

“It is vital that people avoid long periods in the sun – especially in the middle of the day – and find relief in cooler, shadier areas.”

Dr Choong also said anyone playing vigorous outdoor sports was extremely vulnerable during hot weather.

“We advise people to remain mindful that they should take it easy during hot weather, drink lots of water throughout the day, apply effective sunscreen, limit the consumption of dehydrating drinks like caffeine and alcohol, wear head protection and light-coloured, loose-fitting clothing,” he said.

Dr Choong also suggested that people checked on elderly neighbours and to invite them over if they were not coping with the hot weather.

“Also please don’t forget your pets during any hot spell,” he said.

“As a dog owner, I recommend checking fresh water is always available, along with making sure your pets have access to a cool shady place where they can shelter from the heat.”
