Heat index is the measure of the temperature that a person feels, which is different from the actual air temperature. It is computed by factoring in the humidity and the air temperature.

According to PAGASA, heat cramps and heat exhaustion are likely in areas experiencing a danger level heat index, which is from 42 to 51°C. Heat stroke is also possible with continued exposure.

Due to extreme heat, face-to-face classes have been suspended in several areas in the country.

If anyone is experiencing heat stroke symptoms, the Department of Health (DOH) advised concerned individuals to follow these first aid measures:

• Move the person to a shaded, cool area, and provide ventilation.
• Remove the person’s outer clothing.
• Apply cold compresses, ice packs, cold water, or cold wet cloth against the skin, especially on the head, face, neck, armpits, wrists, ankles, and groin. If the patient is conscious, encourage frequent slow sips of cool water.
• Contact emergency services or bring the person to the hospital immediately.

To prevent heat-related illnesses, the DOH advised the public to limit time spent outdoors, drink plenty of water, and avoid tea, coffee, soda, as well as liquor.

People should also use umbrellas, hats, and sleeved clothing outdoors and schedule their heavy-duty activities for the beginning or end of the day when it is cooler.
