CAPIZ – Roxas City recorded a heat index of 42 degrees Celsius on Tuesday, November 3, placing the provincial capital under the “Danger” category, while the municipality of Mambusao registered 40°C, classified under “Extreme Caution,” according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
The high temperatures prompted health authorities to warn residents against prolonged exposure to extreme heat, which could lead to heat exhaustion, heat cramps, and potentially life-threatening heatstroke.
The Department of Health Western Visayas Center for Health Development (DOH WV CHD) also issued a regional health advisory, identifying extreme heat as one of the health threats associated with the ongoing El Niño phenomenon.
Aside from heat-related illnesses, the DOH warned that high temperatures and drought conditions could worsen existing health problems, particularly cardiovascular and hypertensive diseases.
The agency also cited increased risks of vector-borne, waterborne, and foodborne illnesses, as well as aggravated skin and respiratory conditions and a possible rise in animal bite cases.
To prevent heat-related illnesses, health authorities advised residents across Capiz and Western Visayas to drink plenty of clean water throughout the day, even before feeling thirsty.
The public was also urged to avoid prolonged exposure to direct sunlight, particularly between 10 a.m. and 4 p.m., and refrain from strenuous outdoor activities during peak heat hours.
Residents were advised to limit alcoholic beverages, soft drinks, sugary drinks, and excessive caffeine, which may contribute to dehydration.
The DOH also recommended wearing loose, lightweight, light-colored, and breathable clothing, along with using umbrellas, caps, or wide-brimmed hats when going outdoors.
Frequent rest breaks in shaded, cool, and well-ventilated areas were also encouraged.
Individuals with hypertension and cardiovascular conditions were reminded to maintain an adequate supply of their prescribed maintenance medications.
Health officials urged the public to watch for early signs of heat stress, including dizziness, rapid pulse, nausea, weakness, and confusion.
Those experiencing severe symptoms of heat-related illness should seek immediate medical attention./PN
