Under the effect-based classification of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), 33 to 41 degree Celsius is “extreme caution” that can lead to heat cramps and heat exhaustion.
“Continuing activity could lead to heat stroke,” it warned.
Heat index “is a measure of the contribution that high humidity makes with abnormally high temperatures in reducing the body's ability to cool itself,” according to PAGASA.
PAGASA advised the following procedures when a person suffers from heat-related issues:
- Move the person to a shaded spot and lay him down with legs elevated. If conscious, have them sip cool water.
- Remove clothing, apply cool water to the skin and provide ventilation,
- Apply ice packs to the armpits, wrists, ankles, and groin
