Three monitoring stations of the Philippine Atmospheric Geophysical Astronomical Services Administration (PAGASA) have recorded heat indices of 41 degrees celsius and higher.
Heat index refers to the apparent temperature or what people or feel, as the temperature affecting their body.
The NAIA area in Pasay City registered the highest heat index in Metro Manila at 45 degrees celsius at 11AM on Sunday.
PAGASA’s Science Garden in Quezon City meanwhile registered a heat index of 43 degrees Celsius on that same day at 3PM.
The Port Area in Manila meanwhile had a heat index of 41 degrees at 11AM.
The categories of the readings are in the orange or danger zone which means it may cause human discomfort.
“High air temperatures and high relative humidity will give high apparent temperatures or indices,” PAGASA said.
Under 41-45 degrees celsius heat index, people are at risk from suffering heat cramps and heat exhaustion. Continuous activity may also lead to potential heatstroke.
Areas with high heat indices include Appari, Cagayan (46 degrees), Sangley Point, CAbite (45 degrees) and Tuguegarao City (45 degrees).
PAGASA also gave some tips on how to minimize risk under scorching heat:
1. Stay indoors as much as possible, if air conditioning is not available, stay on the lowest floor out of the sunshine
2. Wear lightweight and light colored clothing. Light colors will reflect the sun’s energy.
3. Drink plenty of water regularly. The body needs water to keep cool.
4. Water is the safest liquid to drink during heat emergencies. Avoid drinking liquor because it dehydrates the body.
5. Eat small meals, but eat more often. Avoid eating foods high in protein which can increase metabolic heat.
