Are UV rays worse in autumn than in summer?

It's the same, but people will have a difference in the feeling of temperature Because it's hot in summer, the temperature at which the sun shines on the ** is very high, so people will feel that the ultraviolet rays are strong in the summer and the temperature outside is very low in the autumn People have this feeling That is, it's cold outside, so the intensity of the ultraviolet rays is low This feeling is wrong because it's all the same sun, whether it's autumn or summer, the degree of ultraviolet radiation is the same.

The intensity of ultraviolet rays varies according to the distance of the Sun from the Earth. Ultraviolet rays are definitely available in autumn, but they will not be stronger than in summer, because the sun is far away, but daily sun protection is still required. It's the same in winter, but there is a special situation in winter, and that is a snowy day.

The white reflection of ultraviolet rays is relatively strong, and the snow on the ground will reflect the ultraviolet rays twice, which will hurt us one more time, so remember to protect from the sun on snowy days in winter!!

By standard, UV rays are stronger in summer, but in winter** they are more sensitive to UV rays than in summer.

Winter and spring are the seasons of the year with the lowest levels of ozone in the world. Without the "protective coat" of the ozone layer, UVA (ultraviolet long wave), which accounts for more than 95% of the sun's rays, will unscrupulously penetrate the clouds, regardless of whether it is cloudy or sunny, and even enter the room, directly into the dermis layer of the skin, destroying collagen and elastic fibers, making ** premature aging and sagging, wrinkles and spots.

In addition, in winter, the dry and cold air outside and the dry hot air blown by the indoor air conditioner will slow down the skin's circulatory and metabolic functions, and weaken its self-renewal and repair functions. Under the combined action of ultraviolet rays, it is easy to darken, grow spots, and age.

Generally, it is recommended to use sunscreen with SPF 15 or higher in summer, and sunscreen with SPF 8-15 in winter is fine. "For winter sun protection, it's best to use sunscreen products that can replenish moisture, moisturize and deeply moisturize, and waterproof sunscreens are not suitable for winter use.

In general, ultraviolet rays in summer.

Strong, but in winter** is more sensitive to UV rays than in summer.

Spring and winter are the seasons of the year with the lowest levels of ozone in the world. There is no ozone layer.

The "protective coat", which accounts for more than 95% of the sun's UVA (ultraviolet long wave), will unscrupulously penetrate the clouds, whether sunny or rainy, and even enter the room, directly penetrating the **dermis and destroying collagen.

and elastic fibers, which make ** premature aging sagging, wrinkles and spots.

In addition, the dry and cold outdoor air in winter and the dry and hot air blown by the indoor air conditioner will slow down the circulation and metabolic functions of the air conditioner, and weaken the self-renewal and repair functions of the air conditioner. Under the combined action of ultraviolet rays, Hu chain cover** is easy to blacken, spot and age.

In general, it is recommended to use sunscreen with SPF 15 or higher in summer.

In winter, a sunscreen with SPF 8-15 is sufficient. Xiaohai said in the report that it is best to use sunscreen products that can hydrate, moisturize, and deeply moisturize in winter, and waterproof pants and sunscreen are not suitable for use in winter.

Yuan Hai reminded friends who like skiing and skating: "On ice and snow, the intensity of ultraviolet rays is about the same as that on the beach in summer, and the damage to ** is very serious." So when you go skiing and skating, wear sunscreen with SPF 15 or higher. ”

1. Although the temperature in autumn is not as high as in summer, the sun is not so strong, but the ultraviolet rays in autumn.

Actually, it's even more powerful than in summer, because in the autumn sky the ozone layer.

will become weaker, so it will be easier for ultraviolet rays to penetrate the ozone layer and reach the earth's surface, where they will erode**.

2. Ultraviolet rays are the main culprits that cause ** blackening.

When irradiated by the outer line of the purple lead pin, the self-defense system will be activated, which is a protective response to ultraviolet rays, and the melanocytes located in the ultraviolet cells will proliferate in large quantities to protect the cells from ultraviolet damage through the absorption and scattering of ultraviolet rays. Of course, while the rapid increase of melanocytes protects the health, it also causes the originally white and clear ** to become dull and dull, and all kinds of pigmentation also swoops in.

Strictly speaking, ultraviolet rays in summer are stronger than in winter, but the sensitivity of Dongzhen Jingtian to ultraviolet rays is higher, so it is also necessary to protect against the sun in winter, generally in summer it is recommended to use sunscreen with SPF15 or above, and it is recommended to use SPF8-15, PA+++ sunscreen in winter.

The ultraviolet rays are also very strong in winter, but they are not as easy to tan as in summer, because it is cold in winter, so they rarely go out, and even if they wear thick clothes when they go out, they have less average daily exposure, so they are not as easy to tan as in summer. However, winter and spring are the seasons with the least ozone content in the world in a year, and ultraviolet long-wave (UVA), which accounts for more than 95% of the sun's rays, will penetrate through the clouds, and even enter the room, penetrating deep into the dermis layer of the skin, thereby destroying the skin's collagen and elastic fibers, resulting in premature aging and sagging, wrinkles and spots.

Therefore, in summer, you should choose a sunscreen with a high SPF and waterproof function, and in winter, you should choose a sunscreen with more PA+ numbers, PA refers to the effective degree index of preventing UVA, and the more + signs, the stronger the defense ability, and it is best to take into account the function of hydration and moisturizing.

In winter, ultraviolet rays are not as strong as the spine in summer, and the light is strong in summer, and ultraviolet rays have strong penetration, but in winter, they are more sensitive to ultraviolet rays, so they need to erect and carry a parasol when going out in winter to reduce direct sunlight to the surface, or apply a layer of sunscreen on the surface of the sun, so as to protect human skin.

1. It is stronger in summer

In winter, ultraviolet rays are not as strong as in summer, and the sun directly hits the northern hemisphere in summer, so the light intensity is higher, and it has strong penetration, which is easy to cause direct damage to human skin.

2. Bring a parasol

In winter, you can use a parasol to prevent ultraviolet rays, and the reflective layer of the parasol can inhibit direct sunlight, so you can grammar the human body ** directly exposed to sunlight, and the parasol can basically block most of the ultraviolet rays to avoid being harmed.

3. Apply sunscreen

In winter, you can apply sunscreen to prevent ultraviolet rays, and a protective film will form on the surface after applying sunscreen, and when exposed to ultraviolet rays, the protective film can reflect most of the ultraviolet rays, thereby reducing the UV rays received, thereby protecting skin health.
