Matters needing attention in Tibet tourism:

1. Lhasa has the strongest ultraviolet radiation.

Due to the influence of solar altitude, the ultraviolet radiation in Lhasa is stronger in summer than in winter, but it is wetter in July and August than in June, so the ultraviolet radiation in Lhasa is the strongest in June, and the number of days above Grade 5 accounts for about 60% ~ 70%.

These days, Lhasa has been clear in Wan Li. People in Lhasa have complained about "sunburn" here, and all kinds of umbrellas have become a beautiful landscape on the streets of Lhasa. Therefore, sun protection and sunburn have become a hot topic for the public.

The reporter interviewed the Center for Disease Control and Prevention of the Autonomous Region and the Lhasa Meteorological Observatory respectively, and learned that under normal circumstances, ordinary people can resist sunlight 15 minutes without any protection. In addition, the maximum time of ultraviolet radiation every day is around 13, and the ultraviolet radiation is stronger in summer than in winter.

2. Any protection, the average person can only resist sunlight 15 minutes.

The reporter learned from the Dermatology Department of Xizang Autonomous Region CDC that ultraviolet rays can be divided into UVA, UVB and UVC according to wavelength, and the three bands have different degrees of penetration into human skin. UVC is basically absorbed when it passes through the ozone layer, which has little influence on human body, while UVA and UVB have influence on human body, with the highest UVB content in summer.

"The transmittance of UVB reaches the surface layer of the skin, and UVA can penetrate deep into the dermis." Kang Ping, an attending doctor in the dermatology department of the Center for Disease Control and Prevention of the Autonomous Region, told the reporter that the symptoms of UVB damage to the skin include redness, peeling, pain and blisters. In severe cases, it may cause cancer. UVA can lead to "photoaging" of the skin, and the skin will become rough, long spots and wrinkles.

Kang Ping said that in the absence of any protection, the normal skin of ordinary people can generally resist the sun for 15 minutes, but after 15 minutes, people with different skin types have different abilities to resist the sun and have different degrees of skin damage. It is best not to be exposed to the sun for a long time, or to take good protection when traveling.

3.SPF index and PA index are both important.

According to Kang Ping, an attending dermatologist of Xizang Autonomous Region CDC, there are two kinds of hazards of ultraviolet rays to people, namely UVA suntanned skin and UVA sunburned skin.

"There are many measures to avoid being harmed by ultraviolet rays. For example, it is best to wear sunscreen when going out with umbrellas, sun hats and sunglasses. But remember to buy a physical one to avoid harm to the skin. " Kangping said that ultraviolet rays reflected from the ground can also harm the skin, so an umbrella can't completely resist ultraviolet rays.

Kang Ping said: "As long as the SPF index is anti-UVB and sunscreen black, the PA index is anti-UVA and sunscreen black. An SPF value can make the skin resist 15 minutes of sun exposure, that is, a sunscreen with an SPF value of 30 can resist 7 hours and 30 minutes of sun exposure, and the higher the PA, the better. Generally, you should choose'++',and it is best to choose'++'."

Kangping reminded the public not to use cosmetics containing photosensitive substances, such as spices, in their daily lives. In terms of diet, it is necessary to pay attention to eating a small amount of vegetables containing photosensitive substances, such as lettuce and spinach. "After ingesting photosensitive substances, when there is light, it will aggravate the damage of ultraviolet rays to the skin." Kang Ping said.
