Heatwave in malaysia! How to deal with it?

A heatwave is a prolonged period of excessively hot weather, often accompanied by high humidity. It is characterized by unusually high temperatures that persist for several days or even weeks, exceeding the average seasonal temperatures. Heatwaves can have severe impacts on human health, especially in regions like Southeast Asia, where the climate is already hot and humid.


In Malaysia, a heat wave is classified when the average daily maximum temperature exceeds 37°C for three consecutive days. Which is why the current heatwave is an extraordinary event.





During a heatwave, the body's natural cooling mechanisms, such as sweating, struggle to keep up with the excessive heat, leading to a range of health risks. High temperatures can cause dehydration, heat exhaustion, and heatstroke, which can be life-threatening if not addressed promptly.


The negative impacts of heatwaves on health include:


  • Dehydration: The hot and humid conditions cause excessive sweating, leading to fluid loss from the body. Dehydration can result in dizziness, fatigue, confusion, and increased heart rate.

  • Heat exhaustion: Prolonged exposure to high temperatures can cause heat exhaustion, characterized by heavy sweating, weakness, nausea, and headaches. If not treated, heat exhaustion can progress to heatstroke.

  • Heatstroke: Heatstroke is a severe condition that occurs when the body's core temperature rises above 40 degrees Celsius (104 degrees Fahrenheit). Symptoms include a rapid pulse, hot and dry skin, confusion, and loss of consciousness. Heatstroke is a medical emergency and requires immediate medical attention.


To protect yourself during this current heatwave, consider the following tips:


Stay hydrated: Drink plenty of water and fluids throughout the day, even if you don't feel thirsty. Avoid excessive consumption of caffeinated or alcoholic beverages as they can contribute to dehydration.


  • Stay indoors: Limit your time outdoors, especially during the hottest hours of the day. Seek shade or air-conditioned environments, such as shopping malls, libraries, or community centers.

  • Dress appropriately: Wear loose-fitting, lightweight, and light-colored clothing that allows your skin to breathe. Opt for fabrics like cotton or linen, which absorb sweat and aid in evaporation.

  • Protect yourself from the sun: Wear a wide-brimmed hat, sunglasses, and apply sunscreen with a high SPF to protect your skin from harmful UV rays.

  • Use fans or air conditioning: If available, use fans or air conditioning to cool your living space. If you don't have access to air conditioning, create cross-ventilation by opening windows or using fans to circulate air.

  • Take cool showers or baths: Cool showers or baths can help lower your body temperature and provide temporary relief from the heat.

  • Avoid strenuous activities: Minimize physical exertion, especially during peak heat hours. If you need to engage in outdoor activities, try to schedule them during cooler parts of the day, such as early morning or late evening.

  • Check on vulnerable individuals: Keep an eye on children, the elderly, and those with chronic illnesses, as they are more susceptible to heat-related illnesses. Ensure they are well-hydrated and have access to cool environments.

  • Stay informed: Pay attention to weather forecasts and heatwave warnings issued by local authorities. Stay updated on safety guidelines and recommendations provided by health organizations.

By following these tips and taking appropriate precautions, you can protect yourself and reduce the negative impacts of extreme heat. Stay cool, hydrated, and seek medical assistance if you or someone you know experiences severe symptoms of heat-related illness.
