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

Dangerous level heat index is from 42°C to 51°C, where heat cramps and heat exhaustion are likely. Heat stroke is also possible with continued exposure.

PAGASA advises the public to prevent heat-related illnesses by doing the following:

• Limit the time spent outdoors
• Drink plenty of water
• Avoid tea, coffee, soda, and liquor
• Wear umbrellas, hats, and sleeved clothing outdoors
• Schedule heavy-duty activities for the beginning or end of the day when it's cooler

The Department of Health (DOH) earlier advised the following first aid measures for individuals experiencing heat stroke symptoms:

• 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
• Further, the DOH advised the public to limit time spent outdoors and drink plenty of water. Tea, coffee, soda, and liquor should be avoided, the DOH said, to prevent heat-related illnesses
