為什么要進行紫外線防護?

信息摘要:

紫外線輻射會導致曬傷。長時間暴露在陽光下會損害皮膚細胞,并產生令人不快的曬傷感。已知紫外線會導致皮膚癌的發展,例如黑色素瘤和癌。紫外線可以抑制免疫系統,增加皮膚中癌細胞生長的可能性。曬黑也不是一個好主意。這可能會導致陽光損壞,皮膚和皺紋過早老化。長時間外出時,請始終佩戴防曬霜并嘗試尋找一些陰影。請記住,紫外線僅少量有益于您-太多,最終可能導致灼傷,甚至更糟。

紫外線(UV)來自太陽和其他一些地方,例如曬黑床和特殊的紫外線。太陽的大部分輻射被大氣阻擋,因此只有一小部分到達地球。當您在外面的陽光下度過時光,從陽光中散發出來的紫外線會使您的身體產生維生素D,這是健康人體必需的營養素。每天僅幾分鐘的陽光就能在您的體內產生足夠的維生素D,以改善您的情緒并為您提供能量。適量的維生素D還可以幫助降低患心臟病和高血壓的風險。因此,每天至少要在陽光下玩樂幾分鐘!

但是,紫外線輻射也可能有害,尤其是長時間暴露在紫外線下時。首先,紫外線輻射會導致曬傷。長時間暴露在陽光下會損害皮膚細胞,并產生令人不快的曬傷感。已知紫外線會導致皮膚癌的發展,例如黑色素瘤和癌。紫外線可以抑制免疫系統,增加皮膚中癌細胞生長的可能性。曬黑也不是一個好主意。這可能會導致陽光損壞,皮膚和皺紋過早老化。長時間外出時,請始終佩戴防曬霜并嘗試尋找一些陰影。請記住,紫外線僅少量有益于您-太多,最終可能導致灼傷,甚至更糟。

紫外線會與皮膚一起傷害您的眼睛。太陽光產生的大部分紫外線會被眼睛的前部組織吸收。這可能會損壞角膜并增加黃斑變性和白內障的風險。如果您的眼睛在短時間內暴露在大量陽光下,您可能會遇到稱為光性角膜炎的病狀。盡管這沒有持久的作用,但它很痛苦且不舒服,通常會導致眼睛發紅,灼熱和流水。它類似于皮膚上的曬斑。如果您在外面花費大量時間,那么您的眼睛也可能會遭受長期傷害。累積暴露于紫外線輻射會灼傷角膜,從而影響視力。您還可以在眼前發展白內障,即晶狀體模糊或混濁。

這就是為什么必須戴紫外線防護眼鏡的原因!無論您是在戶外度過大量時間,還是通勤時間短,陰影都能保護您的眼睛免受紫外線輻射的傷害。就像在出門前戴上防曬霜一樣,將防紫外線眼鏡作為優先事項。優先保護眼睛。

UV-Rays.jpg

Ultraviolet radiation (UV) comes from the sun and a few other places, like tanning beds and special ultraviolet lights. Most of the sun’s radiation is blocked by the atmosphere, so only a small percentage reaches the Earth. When you spend time outside in the sunlight, the UV rays that do make it here from the sun cause your body to produce vitamin D, a necessary nutrient for a healthy body. Just a few minutes of sunlight a day can produce enough vitamin D in your body to improve your mood and give you energy. The right amount of vitamin D can also help lower the risks of heart disease and high blood pressure. So have fun in the sun for at least a few minutes a day!

However, UV radiation can also be harmful, especially when you expose yourself to it for extended periods of time. Firstly, UV radiation causes sunburns. Prolonged exposure to sunlight damages skin cells and produces the unpleasant feeling of a sunburn. UV rays are known to cause the development of skin cancers, like melanoma and carcinomas. UV radiation can suppress the immune system, increasing the likelihood of cancerous cell growth in your skin. Too much tanning is not a good idea, either. This can lead to sun-damaged prematurely aging skin and wrinkles. Always wear sunscreen and try to find some shade when you are outside for extended periods. Remember that UV rays are only good for you in small amounts—too much and you might end up with a burn, or worse.

Along with your skin, UV light can also damage your eyes. Most of the ultraviolet radiation from sunlight is absorbed by the front tissue of your eyes. This can cause damage to your corneas and increase your risk for macular degeneration and cataracts. If your eyes are exposed to a large amount of sunlight in just a short period of time, you might experience a condition called photokeratitis. While this has no lasting effects, it is painful and uncomfortable, usually resulting in redness, burning, and watering of the eyes. It is similar to a sunburn on your skin. If you spend a lot of time outside, you could suffer long-term damage to your eyes as well. Cumulative exposure to UV radiation can result in burns to your corneas, which will affect your sight. You can also develop cataracts, a blurred or clouded lens on the front of the eye.

This is why wearing sunglasses is a must! Whether you spend a great deal of time outside, or you only have a short commute, your shades can protect your eyes from UV radiation damage. Just like putting on your sunscreen before heading outside, make sunglasses a priority. Make protecting your eyes a priority.
