CAGAYAN DE ORO CITY (April 10) — Health authorities are raising the alarm as the heat index climbs across Northern Mindanao, warning residents to brace not only for extreme temperatures but also increasing humidity and unstable weather conditions heading into the weekend.
The Department of Health (DOH)-10 issued the advisory following data from DOST-PAGASA showing temperatures ranging from 33°C to 39°C in parts of the region, particularly in Misamis Oriental and Bukidnon.
But while the heat is expected to persist, forecasters say the coming days may bring a different kind of discomfort: humid, “malagkit” conditions with a chance of rain.
Hot days, heavier air
Weather outlooks indicate partly cloudy to cloudy skies through the weekend, with increasing chances of rain showers and thunderstorms from Saturday to Sunday.
Humidity levels are also expected to remain elevated, with recent observations in Mindanao showing relative humidity dropping only to around 60% even during peak afternoon heat—a level that can make temperatures feel significantly hotter.
This combination of heat and moisture can push the heat index higher than actual air temperature, increasing the risk of heat stress.
High-risk groups identified
The DOH flagged children, senior citizens, people with existing medical conditions, and outdoor workers as the most vulnerable.
“These individuals are more prone to dehydration and heat stroke,” said Dr. Vaniza Bagolbol, urging extra caution as humidity worsens the body’s ability to cool itself.
Recognize the warning signs
Early symptoms of heat exhaustion include:
- Headache
- Dizziness
- Nausea
- Fatigue
- Muscle cramps
Health officials advise immediate cooling measures—moving to shade, loosening clothing, and applying cold compresses—while stressing that worsening symptoms require urgent medical attention.
Not just heat—but prolonged exposure
Even with possible rain showers, experts warn this will not necessarily bring relief.
Instead, intermittent rains may trap heat near the surface and raise humidity, prolonging discomfort and compounding health risks, especially for those exposed outdoors for long periods.
Simple habits, critical impact
To stay safe, the DOH recommends:
- Drinking at least 7–8 glasses of water daily (up to 2–3 liters in extreme heat)
- Avoiding outdoor activity from 10 a.m. to 4 p.m.
- Wearing light, loose-fitting clothing
