Safety Measures Against Heat-Related Illnesses

The DOH also recommended wearing loose, lightweight clothing to help keep the body cool during extreme heat conditions.
With the heat index expected to rise in several areas, Pagasa and the DOH continue to urge the public to take precautionary measures to stay safe and avoid heat-related health issues.
