LINGAYEN, Pangasinan — With heat indices reaching "danger" levels in Pangasinan in recent days, the Provincial Health Office on Monday advised residents to avoid prolonged sun exposure to prevent heat-related illnesses, such as heat cramps, heat exhaustion and heat stroke.
Dr. Vivian Villar Espino, provincial health officer, advised residents working outdoors to seek shade and avoid direct sunlight exposure between 10 a.m. and 2 p.m., the peak tanning hours.
A heat index refers to the apparent temperature that the body feels, which can cause discomfort.
"Stay hydrated; that's the best thing you can do. Wear light-colored clothing as much as possible," Espino said.
Light-colored shirts reflect more sunlight and heat, helping to keep a person cooler in hot weather.

Espino also advised political candidates campaigning for the May elections to wear sunblock and schedule activities during the cooler hours of early morning or late afternoon.
"Wear a hat as much as possible to avoid direct sun exposure, and always carry water to stay hydrated," she added.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) recorded heat indices in Pangasinan ranging from 41 C to 48 C from April 3 to April 7.
The forecast heat index for April 8 was 42 C.
According to Pagasa, heat indices between 42 C and 51 C fall within the "danger" level, with a high likelihood of heat cramps, heat exhaustion and potential heat stroke.
A heat index ranging from 33 C to 41 C calls for extreme caution, as heat stroke, heat cramps and heat exhaustion are possible, and continuing activities may lead to heat stroke.
Espino said that victims of heat-related illnesses often experience dehydration, dizziness, and sometimes elevated blood pressure.
Other symptoms include heavy sweating, exhaustion or fatigue, dizziness, light-headedness, blacking out, or feeling dizzy when standing, a weak but fast pulse, nausea, and vomiting.
Espino advised that anyone suffering from a heat-related illness should be moved to a cool area immediately.
"It also helps to apply a cold, wet towel to their chin or head. If their blood pressure rises, it's best to take them to the nearest hospital for proper management," she said.
