As the summer heat intensifies, many spend long hours under the scorching sun without protection.

EJ Grado, a delivery rider, is one of them.

"Wala po. Ganito lang po ako kung mag-duty. Tubig lang talaga," Grado said.

He relies only on water to endure the heat.

According to skin specialist Dr. Vanessa Terbio, prolonged sun exposure can damage the skin seriously.

"‘Pag umabot na ng 44 degrees, yun na yung nagku-cause na ng burn sa balat. Dun na napi-feel yung init. Mahapdi, magiging dark at namamalat," she explained.

Aside from sunburn, excessive sun exposure can lead to heat rashes, dry and itchy skin, and even bacterial infections if scratched.

In severe cases, it can also cause skin discoloration and increase the risk of skin cancer.

Experts recommend avoiding direct sunlight between 10 a.m. and 3 p.m., but for those who cannot avoid going out, applying sunscreen is a must.

"Maglagay ng sunscreen o sunblock — nakakatulong — 30 minutes to one hour before sun exposure," Dr. Terbio said.

Mariel Galinato-Misagal, a nurse, follows this practice religiously.

"Ang ginagawa ko bago ako pumasok sa work, nagpapahid ako ng sunblock. Pag exposed sa araw, every two hours, nagpapahid ulit ako," she said.

For those staying indoors, applying sunscreen every four hours is still recommended.

Taking care of the skin is crucial, especially in extreme weather conditions.
