KUALA LUMPUR — The heatwave currently affecting the country not only increases health risks but may also lead to long-term physiological complications such as heatstroke.

Universiti Putra Malaysia (UPM) public health medicine expert, Associate Prof Dr Malina Osman said health risks from hot weather can be divided into two main categories: acute effects and long-term consequences

She said acute effects include heatstroke, which occurs when the body is continuously exposed to high temperatures until it fails to adapt, subsequently disrupting the cardiovascular system.

“This condition typically affects individuals unaccustomed to heat or those suddenly exposed to high temperatures. It is more pronounced in those with chronic illnesses, such as kidney disease, hypertension, patients undergoing chemotherapy, the elderly, and individuals with autoimmune issues,” she said when contacted by Bernama today.

She added that heatstroke is a grave condition that can be fatal if not treated immediately, while long-term exposure can lead to dehydration, affecting the body’s physiological functions.

“This situation can also exacerbate chronic diseases such as diabetes, hypertension, and kidney problems, besides causing stress and discomfort that can impact mental health, including depression,” she said.

She advised the public to pay special attention to vulnerable groups to ensure they are shielded from extreme heat, and to protect chronic patients and the elderly by ensuring they receive adequate medication and water intake.
