Tibet travel notes:
1. Lhasa ultraviolet radiation is the strongest
By the sun's altitude angle size, Lhasa in summer than the winter of the ultraviolet radiation is strong, but the rainy weather from July to August to be more than June. More than in June, so Lhasa June UV radiation is the strongest, more than five days accounted for about 60% to 70%.
These days, Lhasa has continued to be a sunny situation, Lhasa people have complained of "sun death", all kinds of umbrellas become a bright landscape on the streets of Lhasa. Along with the sunscreen, sunburn and other hot topics of public discussion.
The reporter separately interviewed the regional CDC and Lhasa City Weather Station that, in general, without any protection, the average person can resist sunshine for 15 minutes. In addition, daily around 13:00 for the strongest ultraviolet radiation, the year, the summer ultraviolet radiation is stronger than the winter.
2. any protection, the average person can only resist sunshine 15 minutes
Reporters from the Tibet Autonomous Region CDC Dermatology Division that ultraviolet light according to the wavelength can be divided into UVA, UVB and UVC, the three wavelengths on the human skin penetration is different. UVC through the ozone layer is basically absorbed, the human body does not have much effect, UVA and UVB on the human body, and summer UVB content is the highest. The UVA and UVB have an effect on the human body, and the UVB content is the highest in summer.
"UVB transmittance to the surface layer of the skin, UVA can go deep into the dermis." Regional CDC dermatology attending doctor Kang Ping told reporters, UVB damage to the skin after the symptoms of redness, swelling, peeling, pain, blisters, serious cases may cause cancer, UVA will cause skin damage will appear after the skin "photoaging", the skin will be rough, spots, wrinkles and so on.
Kang Ping said, without any protection, the average person's normal skin can generally resist sun exposure for 15 minutes, but after 15 minutes, people with different skin types to withstand the sun's irradiation capacity is different, the degree of damage to the skin is also different, it is best not to prolonged exposure to the sun, or travel to do a good job of protection.
3. sunscreen SPF index and PA index are important
According to the Tibet Autonomous Region CDC dermatology attending doctor Kang Ping, ultraviolet radiation on the person's hazards there are two kinds of ultraviolet radiation in the UVA tanning skin, and UVA sunburn skin.
"There are many measures to avoid skin damage by ultraviolet rays, for example, go out equipped with umbrellas, sun hats, sunglasses, etc., applying sunscreen is more effective, but remember to choose the shopping rationality, to avoid harm to the skin." Kang Ping said, the ground reflected ultraviolet rays will also harm the skin, so the umbrella does not completely resist ultraviolet radiation.
Kang Ping said: "SPF index as long as the resistance to UVB, to prevent sunburn, PA index is the resistance to UVA, to prevent tanning, an SPF value can allow the skin to resist 15 minutes of sun exposure, that is, the SPF value of 30 sunscreen can resist 7 hours and 30 minutes of sun exposure, and the higher the PA the better, generally to select the '++' and preferably '++++'."
Kang Ping reminded the public, in daily life, try not to use cosmetics containing photosensitive substances, such as fragrances; diet, need to pay attention to a small amount of consumption of vegetables containing photosensitive substances, such as lettuce, spinach and so on. "After ingesting photosensitive substances, when there is light, it will aggravate the damage of ultraviolet rays on the skin." Kang Ping said.
