You have probably heard the term “beauty sleep.” The majority of people think that this is a myth, and such a thing doesn’t exist. But in reality, beauty sleep is the magical process when you go to bed, thinking that your skin looks awful, and in the morning you feel like a totally new person. Your skin is nourished, with fewer wrinkles, hydrated, supple, and vibrant… just as if some kind of magic happened during the night.
Well, it is not exactly magic. In fact, “beauty sleep” is a real thing.
Let’s dive in!
How does beauty sleep work?
The answer may surprise you, but in fact, the Growth hormone is responsible for our skin changes during the night.
The Growth hormone, also known as HGH, is a type of hormone produced in pituitary glands. For the kids and adolescents, it is vital for the growth of their bones and muscles, as well as for the proper functions of the body organs. Many people think that the brain stops excreting HGH once we have grown up. But that is not true at all!
Every person produces Growth hormone in stage 3 of the sleeping process. This is the stage of a deep sleep, which, for adults, continues for about 5-10% of the total sleep duration (for kids and adolescence it is about 20%). The HGH stimulates the regeneration of tissues in the body, such as muscles, bones, and skin. But as we talk about beauty sleep, we will focus on the physical benefits.
The hormone boosts the reproduction of the skin cells and strengthens the lipid barrier of the epidermis. As a result, the skin becomes more resistant to damage caused by external factors, such as pollution, stress, sun radiation, smoking, etc., also known as free radicals. Those radicals cause oxidation of the cells in the body (not only skin) and damage their structure and functions from inside. Shortly said, the process of deep sleep has an antioxidative effect on the body.
On the other hand, HGH stimulates the collagen and elastin production in the dermis. Those are proteins, which are vital to the skin’s health and beauty. They work together and form compounds, which keep the skin’s elasticity and strength.
In short, the synonym of beauty sleep is a deep sleep. This process boosts the skin cells regeneration and reproduction, has an antioxidative effect on them, strengthens the skin barrier, and stimulates the production of collagen and elastin.
