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.

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.

Easterlies

Meanwhile, PAGASA said other parts of the National Capital Region and the rest of the country will have partly cloudy to cloudy skies with isolated rain showers.

The local weather bureau said this is a result of easterlies which continue to be felt all over the country.

The country may also experience light to moderate winds with slight to moderate coastal waters.

Sunrise in Metro Manila will be at 5:35 a.m. on Sunday.  —Jiselle Anne Casucian/ VAL, GMA Integrated News
