DOH warns public of heat-related illnesses as temperatures rise

Filipinos should take precautions against heat-related illnesses such as heat stroke, heat exhaustion, and heat cramps as the hot weather persists, Department of Health (DOH) Assistant Secretary Albert Domingo warned in a radio interview on Saturday.

Domingo emphasized the risks posed by extreme heat and provided guidance on prevention.

According to him, when the heat index reaches 33 to 41 degrees Celsius, individuals may experience heat cramps due to dehydration and the loss of electrolytes. High heat index levels hinder sweat evaporation, making it harder for the body to cool down, which can lead to muscle cramps.

If the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) raises the heat index warning to the danger level (42 to 51 degrees Celsius), people may suffer from heat exhaustion, with symptoms such as extreme fatigue and drowsiness.

At extreme danger levels (52 degrees Celsius and above), the risk of heat stroke significantly increases. Heat stroke is a life-threatening condition that can cause confusion or loss of consciousness due to severe dehydration affecting the brain and nervous system. To prevent it, Domingo advised staying hydrated and keeping cool.

He also noted that heat-related illnesses can occur even in shaded areas due to reflected heat. One key sign of dehydration is thirst, and he stressed the importance of drinking clean water — around seven to eight glasses a day.

"Kailangan uminom ng tubig na malinis, seven to eight glasses a day… Kapag may thirst signal na nauuhaw tayo, senyales ‘yan," Domingo said.

Another indicator of dehydration is the absence of sweating despite high temperatures.

Domingo also recommended checking urine color as a simple way to monitor hydration levels. Light yellow or colorless urine indicates proper hydration, while dark yellow or deep green may signal dehydration. If urine appears red, he urged individuals to seek medical attention as it could indicate a serious health issue.

As temperatures continue to rise, the DOH urges the public to take necessary precautions to avoid heat-related illnesses and ensure their well-being.
