On Saturday, the UV index in Hanoi has been average while it has reached high levels in Quang Ninh Province’s Ha Long City and Hai Phong City in the northern region, and in the southernmost province of Ca Mau, the National Center for Hydro-Meteorological Forecasting reported.

The same day has seen very high UV radiation in Thua Thien Hue Province’s Hue City, Da Nang City, Quang Nam Province’s Hoi An City, and in Ho Chi Minh City and Can Tho City in the southern region.

Specifically, the UV radiation index has been measured 7.5 to 8 in Ha Long and Hai Phong, 8 to 9 in Hue, 8.8 to 9.1 in Hoi An, 7.5 to 9.5 in Da Nang, 7.8 to 9.5 in Khanh Hoa Province’s Nha Trang City, 8.3 – 9 in Can Tho City, and 7.5 to 10 in Ho Chi Minh City – the highest level in the country.

From Sunday until next Tuesday, high UV levels in several cities in the northern part will keep posing a high risk of harm, while those in some cities in the central and southern regions will cause a very high risk, the center warned.

Dr. Le Duc Tho, a dermatologist, told Tuoi Tre (Youth) newspaper UV radiation is harmful and can cause a number of skin conditions including hyperpigmentation, skin aging, sunburn, and skin cancer, as well as eye problems such as cataracts and macular degeneration.

People should apply preventive measures to reduce the impact of ultraviolet on the body, especially during the peak time from 11:00 am to 2:00 pm, doctors said.

When going out, people need to wear protective clothing, use a wide-brimmed hat to cover their face, neck and ears, and wear sunglasses to protect their eyes.

Sunscreen should also be used regularly, even on cloudy days, with special attention during the hours when UV radiation levels reach at its peaks, doctors advised.
