According to Pagasa, 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.”
Heat indices ranging from 42 to 51 degrees Celsius fall under the “danger” category, and people exposed to these heat indices are prone to heat cramps, exhaustion and even heat stroke with drawn-out exposure.
To prevent the effects of the roasting weather, the state weather bureau said the public must limit time spent outdoors; drink plenty of water; avoid tea, coffee, soda and liquor; use umbrellas, wear hats, and wear sleeved clothing outdoors; and schedule heavy-duty activities on the cooler periods of the day.
It also noted that symptoms of heat-related illnesses include heavy sweating, exhaustion or fatigue, dizziness or lightheadedness, blacking out or feeling dizzy when standing, a weak but fast pulse, nausea, and vomiting.
In cases of emergency, Pagasa advised the public to do the following:
Move the person to a shady spot and lie him or her down with legs elevated.
If conscious, have the person sip cool water.
Remove clothing.
Apply cool water to the skin and provide ventilation.
Apply ice packs to the armpits, wrists, ankles and groin.
If the condition of the person worsens, bring him or her to a hospital immediately.
