Health Experts Share Tips to Stay Cool and Safe During Heatwaves

Health experts are urging people to take extra precautions during heatwaves, warning that prolonged exposure to high temperatures can lead to serious illnesses, even for healthy individuals. While air conditioning remains one of the most effective ways to stay cool, experts say there are several practical measures people can adopt to reduce the risk of heat-related illnesses when cooling systems are unavailable. Children, older adults and people with existing medical conditions are considered particularly vulnerable during periods of extreme heat.

Experts note that the risk posed by hot weather depends not only on air temperature but also on humidity, wind, cloud cover and direct sunlight. Indicators such as the Wet Bulb Globe Temperature (WBGT) and the heat index provide a better assessment of heat stress than temperature alone. High humidity makes it more difficult for the body to cool itself through sweating, increasing the likelihood of heat exhaustion and heat stroke even when temperatures are comparatively lower.

People without access to air conditioning are advised to create the coolest possible space inside their homes, use electric fans where appropriate and visit air-conditioned public places such as libraries, shopping malls or community cooling centres whenever possible. Experts also recommend staying well hydrated, wearing lightweight clothing, limiting strenuous outdoor activities during the hottest hours of the day and using cold water or wet towels on the neck, wrists, hands and feet to help lower body temperature.

Workplace safety is another major concern during heatwaves, particularly for outdoor workers. Health specialists advise workers to take regular breaks in shaded areas, drink water frequently and monitor themselves for signs of heat stress. Where available, workers should be aware of heat protection regulations and employer safety guidelines. Individuals exercising outdoors should schedule physical activity during cooler parts of the day and carry sufficient drinking water to prevent dehydration.

Medical experts warn that early symptoms of heat-related illness include excessive sweating, muscle cramps, headache and fatigue. If these symptoms appear, people should immediately move to a cooler location, rest and begin cooling their bodies. More serious warning signs such as dizziness, a rapid heartbeat, confusion, slurred speech or fainting may indicate heat exhaustion or heat stroke, both of which require urgent medical attention.

Experts stress that heat-related illnesses can escalate rapidly if left untreated. Anyone experiencing symptoms of heat stroke, or observing someone who becomes confused, unconscious or unable to cool down, should seek emergency medical assistance immediately. With heatwaves becoming more frequent and intense in many regions, health authorities continue to encourage the public to remain vigilant, stay hydrated and take preventive measures to minimise the health risks associated with extreme temperatures.
