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, for which sleep plays a leading role. 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, appear wrinkles, and even become rough. Lack of sleep can cause skin capillary stasis and blocked circulation, causing skin cells to receive insufficient nutrients, 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.

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 the opportunity to sleep, your beautiful skin may be damaged and become dry, rough, dull, wrinkled, etc. If you have problems with sleep quality, you should take immediate steps to improve it.
What impact does lack of sleep have on skin fitness?
Sleep is an indispensable physiological activity for human beings. For women, sleep has a special function of beauty. Adequate sleep has both physical and psychological benefits for beauty.

Because nighttime is the best time for people's skin cells to regenerate, and they are renewed much faster than during the day. However, urban life is stressful and busy, and 24 hours a day is not enough. Some people tend to reduce sleep to increase working hours; some modern young people like nightlife and stay up all night for "marathon" entertainment. In the long run, it will not only affect the skin Bodybuilding will have a negative impact on health. If you don't sleep well, you will notice a bad complexion in the early morning. Those who suffer from long-term insomnia or lack of sleep may even appear haggard and depressed, which affects their beauty. Therefore, rest time must be allocated well. Work when you work, play when you play, and rest when you rest. You must have at least 8 hours of sleep every day to ensure adequate rest. Good sleep is good for healthy skin, but be careful not to oversleep. For most people, 8 hours of sleep a day is enough. Too much sleep can cause facial swelling or bags under the eyes.
