How can Filipinos beat the heat? PAGASA gave the following tips:

  1. Stay indoors as much as possible, if air conditioning is not available, stay on the lowest floor out, of the sunshine.
  2. Wear lightweight and light colored clothing. Light colors will reflect the sun’s energy.
  3. Drink plenty of water regularly. The body needs water to keep cool.
  4. Water is the safest liquid to drink during heat emergencies. Avoid drinking liquor because it dehydrates the body.
  5. Eat small meals; however, eat more often. Avoid eating food high in protein which can increase metabolic heat.
