37 areas face dangerous heat indices of 42-46°C

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) reported that 37 areas across the country will experience dangerous heat indices ranging from 42 to 46 °C on Friday, May 24.

Laoag City in Ilocos Norte, Aparri in Cagayan, and six other locations including Roxas City and Mambusao in Capiz recorded the highest heat index of 46 °C.

The heat index is a measure of how high humidity contributes to abnormally high temperatures, which can lead to health risks such as heat cramps, exhaustion, and even heat stroke with prolonged exposure.

Pagasa advises limiting outdoor activities, drinking plenty of water, using umbrellas and wearing protective clothing to prevent heat-related illnesses.

Symptoms like heavy sweating, dizziness, nausea, and vomiting indicate the need for immediate medical attention or emergency measures such as moving to a cool place and applying ice packs.
