Many people think that tanning is easy, just "basking in the sun" is enough. In fact, it is not the case. Improper "basking in the sun" will not only prevent tanning, but also endanger health. Unprotected sun exposure will direct ultraviolet rays to the basal layer of the skin, causing sunburn, blisters, and scarring if not handled properly. What's more, inappropriate sunbathing can cause skin cancer. A large group of skin cancers is called basal cell carcinoma of the skin, and the year-over-year increase in the number of white people suffering from this cancer has a lot to do with the wrong sun exposure. With the gradual popularity of tanning in my country, basal cell carcinoma of the skin is also on the rise. In addition, many people sunbathe without paying attention to protecting their eyes, and after the fundus is irradiated by ultraviolet rays, the phacoemulsification may cause fundus lesions or even cataracts.
So, how to sunbathe and tan in a healthy way? The first thing to avoid is the time when the UV rays are the strongest: 10 am to 3 pm. Second, apply sunscreen 20 minutes before going out and every 2 hours while you're sunbathing. Sunscreen should choose a sunscreen with a low UVA coefficient and a high UVB coefficient, which can not only protect the skin from sunburn, but also achieve the purpose of tanning. After Z, also pay attention to your diet and be careful of light-sensitive foods such as onions and tomatoes, which can make you more prone to sunburn when sunbathing.
It is precisely because the effects of sunbathing and tanning are difficult to control that tanning lamps, tanning beds, and tanning machines in tanning salons are gradually accepted. They use sunlight as the principle to mimic the sun's ultraviolet radiation through artificial ultraviolet rays, which are healthier than direct solar ultraviolet rays after filtering out harmful rays. However, tanning enthusiasts should choose a qualified and regular tanning salon, where the UV intensity can be controlled by a computer, and the ideal effect can be achieved under the guidance of a dermatologist.
In addition to artificial UV exposure, tanning products are also seen on the market from time to time. This product contains NEV chemical ingredients, NEV can chemically react with the protein tissue of the skin, making the skin appear brown instantly, and gradually darken over time. "Although this method is easy to apply and easy to operate, it is regarded as the first choice for tanning by many people, but tanning products are also cosmetics and cannot allow the skin to breathe naturally, so it is not recommended for long-term use. Moreover, you must pay attention to the use of tanning products. safety
