Milk contains two hypnotic substances: one is tryptophan, which can promote the nerve cells of the brain to secrete the drowsy neurotransmitter serotonin; the other has the ability to regulate physiological functions. Among them, the "opioid peptides" can combine with the central nervous system to exert opium-like anesthesia and analgesic effects, making people feel comfortable all over the body and helping to relieve fatigue and fall asleep.

So people who want to improve the quality of sleep can drink a little milk before going to bed. Especially for people who are usually busy at work, you can add some fresh pure milk before going to bed at night, which can promote sleep and soothe your mood.

1. Calcium supplementation

The best time to supplement calcium is when you go to bed at night. The calcium in milk is most easily absorbed during this period. Moreover, fresh milk contains phosphorus, potassium, magnesium and other minerals needed by the body. Drinking a large glass of milk every night before going to bed has a good health care effect on body functions. It can not only increase the absorption of beneficial ingredients in food, but also increase the excretion of toxic metals lead and cadmium in food. Milk can reduce the absorption of harmful substances to a certain extent.

2. Beautify and nourish the skin, promote metabolism

Experiments have proven that drinking milk every night has the magical effect of beautifying and nourishing the skin. Research shows that the rate of human cell renewal is greatest during human sleep, and new cells can continue to emerge.

Because the time when human skin cells divide is very special, it is limited to night time. Therefore, drinking milk before going to bed ensures that the skin has sufficient nutrition, and is also beneficial to the metabolism of the skin, creating more new cells. It makes the skin healthier, more shiny and elastic, and can also effectively delay aging and keep youth forever.
