Heat stress occurs when our body is unable to cool itself enough to maintain a healthy temperature. Normally, the body cools itself by sweating, but sometimes sweating isn’t enough and the body temperature keeps rising.
Heat-related illness can range from mild conditions such as a rash or cramps to very serious conditions such as heatstroke, which can kill.
What is a heatwave?
- A heatwave is a period of excessively hot weather.
Why are heatwaves a problem?
- Heatwaves can cause people to become ill, and sometimes die.
- Heatwaves are most dangerous if they occur early in the summer season, if they last for several days, and if they include hot nights.
- Heatwaves can cause fatigue, heat rash, heat cramps, heat exhaustion and heat stroke. Heat exhaustion and heat stroke can lead to death.
- Heatwaves also cause death by causing a worsening of existing health problems, especially heart or lung disorders.
Who is most at risk?
In an aged care facility, all residents are at risk of heat-related illness.
Those residents most at risk are:
- aged 65 years or older
- overweight or obese
- people with a chronic disease, such as heart disease, high blood pressure, diabetes, cancer, kidney disease
- people unable to care for themselves
- people with a health condition that impairs sweating, such as scleroderma, extensive scarring from burns
- people with limited mobility or confined to bed
- people with dementia or psychiatric illness
- people taking medications that interfere with the body’s ability to regulate temperature.
