The US’ National Weather Service said heat index or apparent temperature, “is what the temperature feels like to the human body when relative humidity is combined with the air temperature.  This has important considerations for the human body’s comfort.  When the body gets too hot, it begins to perspire or sweat to cool itself off.”


People exposed to these heat indices are prone to heat cramps, exhaustion, and even heat stroke with drawn-out exposure.

To prevent the effects of roasting weather, Pagasa said the public must limit time spent outdoors, drink plenty of water, avoid tea, coffee, soda, and liquor, use umbrellas, wear hats, sleeved clothing outdoors and schedule strenuous activities on the cooler periods of the day.
