MANILA, Philippines — The heat index in six locations across the nation soared to dangerous levels on Thursday, according to the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (Pagasa).

The state weather bureau defines heat index as “a measure of the contribution that high humidity makes with abnormally high temperatures in reducing the body’s ability to cool itself.”

A heat index between 42ºC to 51ºC is under the “danger category” and may potentially cause heat cramps, heat exhaustion, heat stroke during continued exposure, and other heat related illnesses.

Based on Pagasa’s latest computed heat index as of 5:00 p.m. on Thursday, April 11, the following areas registered a heat index of 42ºC or higher:

1. Dagupan City, Pangasinan – 44ºC
2. Bacnotan, La Union – 42ºC
3. Aborlan, Palawan – 42ºC
4. Masbate City, Masbate – 42ºC
5. Catarman, Northern Samar – 43ºC 
6. Cotabato City, Maguindanao – 42ºC

Dagupan City and Aborlan have consistently recorded a dangerous heat index in the past week.

Pagasa reminded the public of heat related illnesses’ symptoms which include heavy sweating, exhaustion or fatigue, dizziness or lightheadedness, blacking out or feeling dizzy when standing, weak but fast pulse, nausea and vomiting.

Such effects can be prevented by limiting the time spent outdoors; drinking plenty of water; avoiding tea, coffee, soda and liquor; wearing umbrellas, hats and sleeved clothing outdoors; and scheduling heavy-duty activities on the cooler periods of the day.

In cases of heat-related emergencies, Pagasa reminded the public to do the following:

• Move the person to a shady spot and lie him/her down with legs elevated 
• If conscious, have them sip cool water
• Loosen clothing, apply cool water to the skin and provide ventilation
• Apply ice packs to the armpits, wrists, ankles, and groin
• Bring to hospital immediately
