Mackay Hospital and Health Service emergency department doctors are urging communities to be sun safe and heat-illness aware as summer temperatures rise across the Mackay, Isaac and Whitsunday regions.
In the past month, 43 people presented to Mackay HHS emergency departments with heat-related illnesses.
Mackay Base Hospital assistant clinical director Dr Bauke Hovinga said it’s very easy to become affected by hot Queensland temperatures during summer.
“It’s important to remember the risks associated with being out in the sun enjoying activities or while at home,” Dr Hovinga said.
“People are at greater risk of health problems during hot weather conditions because our bodies can overheat easily.
“Our body’s natural defence against overheating is sweating. Sweat evaporates from our skin and helps to cool us down.
“But in some situations, our body can’t sweat enough to stay cool, or sweating alone won’t combat the conditions we’re facing which can cause our body temperature to rise to dangerous levels.”
Dr Hovinga said heat-related illnesses can range from mild heat rashes to heat exhaustion and heatstroke, and the most serious cases can be fatal.
“Heat exhaustion usually develops over 24 hours. Symptoms may include muscle cramps, heavy sweating, paleness, dizziness, nausea or vomiting and fainting.
“However, symptoms can also develop quickly. A rise in body temperature from 37°C to above 40.5°C can cause potentially fatal conditions like heatstroke.”
Being prepared for hot conditions and staying cool is key to avoiding a heat-related illness.
“Stay out of the sun during the hottest parts of the day, drink water regularly and monitor your health,” he said.
“Wear a hat, sunscreen and sunglasses, and where possible, a long-sleeved shirt to protect you from the sun.
“Try and stay indoors in very hot weather, preferably in an air-conditioned building or ensure that there is good air flow with fans and open windows.
“If a heat-related illness is suspected, make sure the person is out of the sun and lay them in a cool shaded place, give them sips of cool fluid and seek medical help immediately, as this is a life-threatening emergency.”
Dr Hovinga said certain groups of people are more prone to heat-related illnesses including the elderly, infants, disadvantaged and people with some pre-existing health conditions, but anyone can fall victim.
“Monitor family, friends and even neighbours who may be more prone to a heat-related illness,”he said.
“The elderly tend to dress warm even in hotter weather so check on them and make sure they are ok.
“However, all Queenslanders can be affected, even if you’re fit and healthy.”
