A heat index is “a measure of the contribution that high humidity makes with abnormally high temperatures in reducing the body’s ability to cool itself,” it also noted.

To prevent the effects of high heat, Pagasa said the public must limit time spent outdoors; drink plenty of water; avoid tea, coffee, soda, and liquor; wear umbrellas, hats, and sleeved clothing outdoors; and schedule heavy-duty activities on the cooler periods of the day.

It said that symptoms of heat-related illnesses include heavy sweating, exhaustion or fatigue, dizziness or lightheadedness, blacking out or feeling dizzy when standing, a weak but fast pulse, nausea, and vomiting.
