Metro Manila (CNN Philippines, May 14) – The heat index in Dagupan City, Pangasinan reached a new record-high on Friday at 53 degrees Celsius (°C).
The 53°C heat index was recorded at 2 p.m., according to state weather bureau PAGASA.
It surpassed the 52°C recorded in the same city on Wednesday, as confirmed by the Dagupan City Public Information Office.
Other places which tallied high heat index levels on Friday are Sangley Point in Cavite (47°C), San Jose town in Occidental Mindoro (44°C), Laoag City in Ilocos Norte (44°C), Ambulong in Batangas (43°C), and Masbate City in Masbate (43°C).
In Metro Manila, PAGASA recorded a 40°C heat index at its Science Garden in Quezon City with a temperature reaching to 36.2°C at 3 p.m., and a 41°C heat index at the Ninoy Aquino International Airport in Pasay City.
PAGASA defines heat index as the “apparent” temperature, or what humans perceive or feel as the temperature affecting their body.
To deal with such high temperatures, the public is advised to stay indoors as much as possible. Regular hydration is highly encouraged, as the body needs water to remain cool. Liquor, meanwhile, is discouraged during heat emergencies as alcohol dehydrates the body.
Individuals must also eat small but more often, PAGASA said, while avoiding high-protein foods as they increase metabolic heat.
Should one need to go outdoors, wear lightweight clothing with light colors as they reflect the sun’s energy, the agency added.
