Heat index is the measure of the temperature that a person feels, which is different from the actual air temperature. It is computed by factoring in the humidity and the air temperature.

PAGASA said heat cramps and heat exhaustion are likely in areas experiencing a danger level heat index, which is from 42°C to 51°C. Heat stroke is also possible with continued exposure.

To prevent heat-related illnesses, the Department of Health advised the public to limit time spent outdoors, drink plenty of water, and avoid tea, coffee, soda, and liquor.

People should also use umbrellas, hats, and sleeved clothing outdoors and schedule their heavy-duty activities for the beginning or end of the day when it is cooler. — VBL, GMA Integrated News
