#HEALTH: Coping with A Heatwave

08 May 2023

Cases of heat-related illnesses have been reported recently including deaths among children. Rising temperatures can lead to heat stroke and severe dehydration.

There are individuals who are at higher risk when exposed to hot weather and age, health, physical condition and the environment they are in, all play a role.

However, everyone should take extra precautions to reduce their exposure to the current hot weather as it can affect health and wellbeing, says Sunway Medical Centre consultant paediatric endocrinologist, Dr Ch'ng Tong Wooi.

As hot weather is prevalent in many parts of the country, it is important for individuals, especially parents, to be able to recognise the symptoms of heat stroke early. Among the symptoms are a high body temperature (40°C or higher); lethargy, headache, nausea and dizziness; having trouble breathing; confusion or disorientation; and loss of consciousness.

Dr Ch'ng says if one is exposed to extreme heat, one should focus on releasing heat from the body.

"Drink enough fluid as this will quickly rehydrate our body. We can also drink fruit juice with added water or sport drinks to replenish electrolytes."

As for being in hot surroundings, especially for children in schools, Dr Ch'ng points out that everyone needs to be cautious once the temperature reaches 33°C or higher.

In schools, teachers can monitor students' condition and act quickly when they see symptoms of heat stroke. Schools should also take preventive measures to avoid heat stroke.

"Use sunscreen when outdoors and minimise outdoor activities as much as possible."

Dr Ch’ng says everyone needs to be cautious once the temperature reaches 33°C or higher.

Factors that contribute to the risk of having a heat stroke include:

Age

Individuals aged 65 years old and above, and young children aged 5 and below are more at risk because it is harder for them to regulate their body temperature

Health or physical condition

Chronic diseases patients, for example individuals with diabetes, respiratory conditions and heart diseases, or individuals who are taking medications that may be affected by extreme heat.

Expectant and nursing mothers are at risk too as they are more likely to become dehydrated.

Surroundings

Working individuals who are exposed to the hot weather, for example farmers or construction workers.
