Hello, no, drinking milk at night has many benefits, because milk contains L tryptophan, a biochemical substance that can make people feel tired and sleepy, and a small amount of morphine, all of which have certain sedative and hypnotic effects, especially L tryptophan, which is the main raw material for the brain to synthesize hydroxyl color. Serotonin plays a key role in brain sleep, which can temporarily inhibit brain thinking activities, thus making people want to sleep, without any side effects. Moreover, milk can be absorbed on the stomach wall, and calcium in milk can also remove tension, so it is more conducive to the sleep of the elderly, so drinking milk at night is conducive to people's rest and sleep.

Drinking milk before going to bed is beneficial to the body's absorption and utilization of calcium. Most of the calcium taken in dinner is absorbed and utilized by the human body before going to bed. After sleep, especially after midnight, the level of blood calcium will gradually decrease, and the decrease of blood calcium will promote hyperparathyroidism. Hormones will act on bone tissue, so that part of calcium in bone tissue will be dissolved into blood, and the stable balance of blood calcium will be maintained. This dissolution is a self-regulating function of human body, which will become one of the causes of osteoporosis after a long time. Drink milk before going to bed at night. Calcium in milk can be slowly absorbed by blood, and blood calcium can be supplemented to maintain the balance all night, so there is no need to dissolve calcium in bones to prevent bone loss and osteoporosis.
