PAGASA defines heat index as the measure of the temperature that a person feels, which is different from the actual air temperature. It is computed by factoring in humidity and air temperature.

In areas with a danger level heat index, which is from 42°C to 51°C, heat cramps and heat exhaustion are likely, according to PAGASA. Heat stroke is also possible with continued exposure.

PAGASA recommends limited outdoor activity, consistent hydration, and wearing fresh clothes to combat the effects of intense heat. — VBL, GMA Integrated News
