From 3 to 5 March, people in the central and northern parts of Viet Nam, including Da Nang, are likely to see ultraviolet (UV) index hit high to very high risk levels, Viet Nam's National Centre for Hydro-Meteorological Forecasting warned.

Medical experts warn that high UV levels can accelerate skin aging and pose more severe threats to human health like skin cancer.

Over the next three days, Thua Thien-Hue, Da Nang and Hoi An, for instance, are likely to brace for the UV radiation at 7-10 levels, dangerous levels that can cause eye damage, overheating and dehydration to those exposed to direct sunlight during the hot weather.

Meanwhile, the UV index in the southern Vietnamese region has risen to extreme levels. Nha Trang, Khanh Hoa and Ho Chi Minh City are expected to suffer the UV rays at 8- 11 levels.

In light of prolonged hot weather with very high UV rays posing an increased risk of health problems, people in the affected localities are now advised by health experts to take the initiative to protect themselves from UV damage triggered by much sun exposure. 

Staying out of the sun is the best way to avoid sun damage. Other precautions should be taken for both skin and eyes include using sunscreen, wearing protective clothing, and avoiding direct sunlight around midday when UV rays are strongest.

The World Health Organisation (WHO) warns the UV index reading 8 to 10 can burn skin within 25 minutes.

Meanwhile, the UV Index reading of 11 or more puts you at a very high risk of harm from unprotected sun exposure, and people may burn if they are exposed to direct sunlight during the hot weather in 10 minutes. The UV Index of 12 means extreme risk of harm from unprotected sun exposure.
