The heat index refers to the temperature felt by the human body when relative humidity is combined with actual air temperature.

High humidity slows the evaporation of sweat, making it more difficult for the body to cool down.

PAGASA advised the public to limit their time outside and use umbrellas or caps when outdoors. It also recommended drinking lots of water and avoiding the intake of tea, coffee, alcohol, and sodas. —Lyjah Tiffany Bonzo/LDF, GMA News
