PAGASA warns of dangerous heat indexes in 6 areas due to El Niño

PAGASA has issued warnings about dangerously high heat indexes in several parts of the Philippines due to El Niño.

As of April 12, six areas registered dangerous heat indexes between 42°C to 51°C: Dagupan City (43°C), Puerto Princesa and Aborlan (both 42°C) in Palawan, Roxas City and Iloilo City (both 43°C) in the Visayas, and Cotabato City (42°C).

Extended exposure to extreme heat can lead to dehydration and other illnesses such as heat cramps, heat exhaustion, and heat stroke, which can be fatal.

Symptoms of these conditions include heavy sweating, fatigue, dizziness, nausea, vomiting, a weak but fast pulse, and blacking out when standing.

People at risk include the elderly, infants, those with chronic illnesses like hyperthyroidism, individuals on certain medications such as diuretics, athletes, and people who regularly exert themselves outdoors.

To prevent heat-related emergencies, Pagasa advises limiting outdoor activities, drinking plenty of water, avoiding tea, coffee, soda, and liquor, using umbrellas, hats, and sleeved clothing, and scheduling strenuous activities during cooler periods.
