39 areas in PH hit dangerous heat indexes, Pagasa warns

On Thursday, April 25, thirty-nine areas across the Philippines recorded dangerous heat indexes, with Dagupan City in Pangasinan and Aparri in Cagayan reaching a peak of 47°C.

Pagasa defines the heat index as a measure that combines high temperatures and humidity, which can impair the body's ability to cool itself and lead to heat cramps, exhaustion, or stroke.

Sangley Point in Cavite is expected to hit 45°C on Thursday, followed by Naia in Pasay City with up to 44°C, while other areas nationwide may also have dangerous heat indexes ranging from 42°C to 51°C.

Pagasa advised the public to take precautions such as moving to a shaded area and drinking cool water if experiencing heat-related symptoms, and to seek medical attention immediately if necessary.

To alleviate symptoms, Pagasa recommends removing excess clothing, applying ice packs to pulse points, ensuring proper ventilation, limiting outdoor time, drinking plenty of water, using umbrellas, wearing hats and sleeved clothing outdoors, and scheduling heavy-duty activities during the cooler periods of the day.
