The Department of Health (DOH) said that heat-related illnesses become more prevalent with extreme temperatures, such as heat cramps, heat exhaustion, and heat stroke.

The public is thus advised to drink lots of water, and stay in a place that has a shade or is cooler.

People should also limit their outdoor activities from 10 a.m. to 4 p.m.; use protection against sunburn such as hats, umbrellas, and sunblock; and wear loose and lightweight clothing.  — Mariel Celine Serquiña/BAP, GMA Integrated News
