Sunlight can be seen everywhere, but why does it get old in the sun?

Sunburn the epidermal cells of the skin and destroy the stratum corneum, which is the skin's moisturizing and water-locking barrier! It makes the skin dry and dehydrated, the elastic fibers in the dermis are damaged, fine lines and wrinkles are produced, and then it is slack and drooping.

sun protection and anti-aging actually mean avoiding excessive exposure. When we go to the plateau or the seaside, or in the hot summer sun, we definitely need to do a good job of sun protection.

But the soft sunlight should not be too comfortable. In fact, it is also very good for our health.

The sun is the source of all things, and life cannot thrive without it. Even when our architects design and build houses, they will design and adjust houses with reference to the "sunshine standard" to ensure the normal demand for sunshine.

You only need 1-3 minutes of sunshine bath every day to meet the requirement of calcium absorption, instead of basking in the sun all day. Therefore, the sun still needs to be basked in, and sunscreen should be applied.

vitamin d is produced to promote the absorption of calcium, which is of great benefit to the body. On the other hand, you can't be exposed to the hot sun for a long time, which will make your skin aging and rough, especially in the hot summer sun, which will burn your skin and even make people suffer from heatstroke. Severe heatstroke can also cause heat stroke and endanger your life.

You see, the ancients didn't have sunscreen, so they basked in the sun every day. It's just that modern people's physique is too poor, so let's bask in it properly.

Spit out sunscreen and bask in the sun, haha. It depends on your needs.

I vomited sunscreen on my neck and face, and it's good to get some sunshine, which not only protects me from the sun, but also gives me some sunshine.

This is the difference between the rural elderly and the urban elderly. The rural elderly can only pass the time like this, because their children are too busy to spend time, and the local conditions are poor. The most important thing is that they don't get much retirement salary every month, so they have to get some sunshine to supplement calcium. Old people in cities are paid a lot of retirement wages to dance dam, fish, play mahjong and travel.

In fact, in winter, when there is nothing to do, it is warmer to bask in the sun outside, so they can bask in the whole body, but the fire only burns to the front, but not to the back. There is not a common saying in the ancients that "the front is burnt and the back is cold."
