The heat index is the actual feel of the temperature in one’s body. It is the human discomfort index that gives the “apparent” temperature or what humans perceive or feel as the temperature affecting their bodies.
A heat index of 32 to 41 degrees Celsius is categorized under “Extreme Caution.” The danger levels are between 41 to 54 degrees Celsius.
Heat cramps and heat exhaustion are possible and continuing activity could result in heat stroke under the “Extreme Caution” category.
Pagasa advises the public to stay indoors, and if there is no air-conditioning available, they should stay on the lowest floor out of the sunshine.
The public is also advised to wear lightweight and light-colored clothing; drink plenty of water; and eat small meals and often.
“Avoid eating foods high in protein which can increase metabolic heat,” Pagasa said.
Drinking liquor should also be avoided as it dehydrates the body. IDL
