KUCHING: The Southwest Monsoon is expected to begin on May 10 and continue until September, bringing prolonged dry weather and fewer rainy days across the country.
According to the Malaysian Meteorological Department (MetMalaysia), localised and transboundary haze may also occur if open burning is not controlled during the peak of the season.
In response, Medical Officer, Dr Jawing Chunggat, has advised the public to minimise outdoor exposure and adopt preventive steps to reduce heat-related health risks.
“Children, the elderly and those with existing health conditions are more vulnerable to heat exhaustion and heatstroke,” he said when contacted by the Sarawak Tribune.
He added that people should avoid strenuous outdoor activities, or limit them to early mornings or late evenings when temperatures are relatively lower.
Among the signs of heat exhaustion are muscle cramps, headaches, nausea, vomiting, dizziness, cold sweats, fatigue and an overall feeling of malaise.
“Heat exhaustion can escalate into heatstroke, where the body temperature exceeds 40 degrees Celsius, and the person may become restless or confused,” he said.
He added that symptoms of heatstroke also include slurred speech, fast and shallow breathing, seizures or even loss of consciousness in severe cases.
Dr Jawing also reminded the public to adopt simple yet important lifestyle adjustments to reduce the risk of heat-related health issues.
These include drinking at least eight glasses of water a day, or more if spending time outdoors or under direct sunlight.
People working under the sun should wear a broad hat or cap, and if possible, use an umbrella to minimise direct exposure.
“Wear loose, light clothing to help your body cool down,” he added.
Dr Jawing also stressed his advice of never to leave anyone in enclosed spaces under the hot sun, including parked vehicles or unventilated tents.
