The effect of sleep on skin

The color of skin depends on the content and location of melanin in epidermal cells and the degree of contraction and expansion of skin blood vessels. These factors are controlled by the regulation of the neurohumoral endocrine system, and sleep plays a leading role in this. During sleep, skin capillary circulation increases, and its secretion and clearance processes are strengthened, accelerating skin regeneration.

Smooth, rosy, and elastic skin depends on the adequate supply of nutrients from the capillaries in the subdermal tissue of the skin. When the skin capillaries are unobstructed, the skin will be ruddy and shiny; otherwise, the skin will be dark, or pale, and lack nutrients, causing the subcutaneous cells to age rapidly, wrinkles, and even become rough. Lack of sleep can cause skin capillary stasis and blocked circulation, causing skin cells to not receive adequate nutrition, thus affecting skin metabolism, accelerating skin aging, and making skin look dull and pale.

After people get enough sleep, they can improve the circulation of skin terminals, eliminate stasis of skin capillaries, fully supply the nutrients needed by skin tissue cells, and correct and prevent premature skin aging.

Dark circles under the eyes are one of the cosmetic flaws. Lack of sleep or frequent insomnia can cause changes in the pigment of the skin around the eyes, causing dark circles; lack of sleep can also make the whites of the eyes cloudy, and cloudy eyes give people the impression of being old and tired; long-term lack of sleep can cause dark circles at the corners of the eyes. Crow's feet are bound to appear prematurely, and no amount of cosmetics will help.

Sleep and skin care

To maintain healthy skin, you must pay attention to nutrition, cleanliness, etc. In addition to day creams, commercially available cosmetics also include night creams that are specially designed to be applied before going to bed. The advertisements claim that applying night cream at night can nourish the skin. In fact, there are no blood vessels in the epidermis, the outermost layer of the skin. Its nutrients come from the blood supply of the dermis, and the absorption function of the epidermis is quite limited, so it is obviously unreasonable from the perspective of skin protection.

How can we ensure that our skin has enough nutrients? Just like people need timely rest, skin also needs reasonable rest and care. The skin's metabolism is most vigorous at night, and its blood supply is most abundant during sleep. At this time, the muscles, internal organs, and especially the consumption system of the human body are in a relatively bottleneck state, while the blood vessels of the skin are completely open, and the blood can fully reach the skin, providing it with sufficient nutrients and oxygen. With the supply of blood, the skin repairs and regenerates itself, preventing and delaying skin aging. Therefore, the beauty of skin is actually conceived in sleep. If you miss this good opportunity of sleep, I'm afraid your beautiful skin will be damaged and become dry, rough, dull, wrinkled, etc.

If you have problems with your sleep quality, you should take immediate steps to improve it.
