On Tuesday, Nov. 10, only the weather station in Dumangas, Iloilo logged a “danger” level heat index at 42°C.

PAGASA cautioned that in areas under a danger-level heat index, heat cramps and heat exhaustion "are likely," while heat stroke "is probable with continued exposure."

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 outdoor activity and wear hats or use umbrellas when outside.

The state weather bureau also recommended staying hydrated by drinking plenty of water while avoiding tea, coffee, alcohol, and carbonated drinks. — BAP, GMA News
