Glass can absorb and block ultraviolet rays. Sunbathing through glass cannot have good health effects.
According to Tianqi Life's investigation, we cannot bask in the sun through glass, because glass can absorb and block ultraviolet rays. Sunbathing through glass cannot have good health effects. Sunbathing can replenish yang energy in the body, but ultraviolet rays are the main source of heat. UVA contained in ultraviolet rays can pass through glass and act on the skin, causing it to tan and cause damage to the skin, therefore basking in the body. the sun through the glass cannot play this role.
Glass is an amorphous solid with an irregular structure. Its main components are silica and other oxides. It is widely used in buildings to insulate against wind andlight. Glass is composed of a variety of inorganic minerals and a small amount of auxiliary raw materials. According to different functions, glass can be divided into tempered glass, colored glass, laminated glass, insulating glass, flat glass, transparent glass and other types.
Will people tan through glass?
Although we are not directly exposed to the sun, glass cannot completely block the sun's ultraviolet rays, but we let's stay under the sun for a long time. time Ultraviolet light stimulates melanocytes under the skin to secrete melanin, making our skin darker.
Ultraviolet light is an electromagnetic wave with a shorter wavelength than visible light, with a wavelength between 390 and 400 nanometers, and is located in the spectrum of violet light outdoors. It has a fluorescent effect and can make fluorescent substances glow. He cant pass through the air, but some of it will be lost through the glass and it will still turn black after a long time. Life care:
Don't be too nervous.
Good daily exposure to the sun is also very useful in promoting the absorption of vitamin D in our skin.
As long as you do. do not expose yourself to the sun for a long time, you can rest assured!
I hope this can help you
People will tan through glass.
Although you are basking in the sun through the glass, the glass is after all completely transparent, so the sun can shine directly on the skin, and through long-term stimulation term of ultraviolet. sunlight, it will damage human skin. Melanocytes produce a certain amount of melanin. The factors that cause melanin production mainly depend on individual differencesand time spent in the sun.
No matter how long you have been in the sun, if you feel any discomfort, you should stop basking in the sun. If you stay in the sun for a long time, your skin may also gradually darken, mainly because melanocytes are stimulated by ultraviolet rays, resulting in the formation of certain melanin particles. If the melanin particles are densely distributed, the skin color will be darker.
Sun protection methods:
1. Try to avoid exposure to the sun when you go out
Avoid 10 a.m. when you go out. to 3 p.m. because ultraviolet rays are strongest during this time. Also try to avoid places like beaches and mountain peaks.
2. Take with you an anti-UV umbrella and a sun hat

These can only block part of the raysns ultraviolet and are UV resistant. Sun hats cannot block ultraviolet rays reflected from the ground.
3. Repeated application of sunscreen
Sweating or wiping with a towel will reduce the effect of sunscreen. Repeated application does not achieve new protection, but maintains the effect of the sunscreen. , Even water alone will affect the function of sunscreen as long as it is covered with sunscreen, so sunscreen needs to be reapplied after swimming or sweating.
4. Avoid going out at midday
UVB at midday is around 100 times higher than in the morning and evening. Everyone must therefore avoid going out at midday, in order to protect themselves effectively.
5. Use sunscreen generously
The protection of sunscreen depends not only on the composition and coefficient of the sunscreen, but also on the thickness and uniformity of wiping. Sunscreen shouldbe applied after skin care products.
