TACLOBAN CITY: Several areas in Eastern Visayas continued to experience dangerous heat index levels on Wednesday (May 27), prompting authorities to urge residents to limit outdoor activities and protect themselves from heat-related illnesses.
As early as 9am, the town of Guiuan recorded a heat index of 45 degrees Celsius, the highest in the region for the day, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa).
A heat index refers to the temperature the human body feels when humidity is combined with the actual air temperature. Pagasa classifies heat indices between 42°C and 51°C as the “danger” category, which increases the risk of heat cramps, heat exhaustion, and heat stroke with prolonged sun exposure.
Local officials in Guiuan immediately reminded residents to avoid direct exposure to extreme heat, especially during peak afternoon hours, to prevent heat-related illnesses.
Other areas in Eastern Visayas also recorded high heat indices. Borongan, Eastern Samar, logged 43°C, while Catarman in Northern Samar reached 44°C.
Health authorities across the region warned that prolonged exposure to extreme heat could lead to dehydration, heat exhaustion, and even heat stroke, a potentially life-threatening condition characterized by high body temperature, dizziness, confusion, and loss of consciousness.
Residents were advised to stay indoors whenever possible, drink plenty of water, wear light and loose-fitting clothing, and avoid strenuous physical activities under the sun.
Authorities also encouraged the public to check on children, senior citizens, and individuals with existing medical conditions who are more vulnerable to extreme heat. - Philippine Daily Inquirer/ANN
