What is Heat Exhaustion?
Heat exhaustion is a type of heat-related illness that occurs when your body overheats and can’t cool itself down properly. This can happen when you are exposed to high temperatures for a prolonged period, or when you engage in strenuous physical activity in hot and humid conditions.
When you are exposed to high temperatures, your body sweats to cool itself down. But in certain conditions – such as high humidity, lack of air movement, or excessive physical activity – sweating may not be enough to dissipate the heat. This can cause your body temperature to rise rapidly, leading to heat exhaustion.
There are several factors that can increase your risk of developing heat exhaustion. These include:
| Factors that can increase your risk of heat exhaustion |
|---|
| Working or exercising outdoors in hot and humid conditions |
| Wearing heavy or tight clothing that traps heat |
| Being dehydrated or not drinking enough fluids |
| Having a pre-existing medical condition that affects your sweating or circulation, such as diabetes or heart disease |
| Taking certain medications that can impair your body’s ability to regulate its temperature, such as diuretics or antihistamines |
If you are at risk of heat exhaustion, it is important to be aware of the early warning signs and take steps to prevent it from progressing to a more serious condition.
Early Signs of Heat Exhaustion
Recognizing the early signs of heat exhaustion is crucial for staying safe in Australia’s hot climate. Some common symptoms to look out for include:
