Whether you can sleep well at night, what you eat at night is very important. The Yellow Emperor’s Classic of Internal Medicine has “stomach does not fit is restless”, clinical nutritionists also pointed out that one of the causes of sleep disorders is to eat some “inappropriate” food in dinner. So, what is good for sleep at night, and what food will keep you up at night! 1, caffeine: many people know that food containing caffeine will stimulate the nervous system, but also has a certain diuretic effect, is a common cause of insomnia. 2, spicy food: In fact, in addition to this, dinner eating spicy food is also an important reason to affect sleep. Chili, garlic, onions, etc. can cause a burning sensation in the stomach and indigestion, which in turn affects sleep. 3, greasy food: greasy food after eating will increase the workload of the intestines, stomach, liver, gallbladder and pancreas, stimulating the nerve center, so that it has been in a state of work, which can also lead to insomnia. 4, food with satiety: There are also some foods that produce more gas during digestion, which produces a sense of bloating and prevents normal sleep, such as beans, cabbage, onions, corn, bananas, etc. 5, alcohol: Drinking alcohol before bedtime was once thought by many to promote sleep, but recent studies have proved that although it can make people fall asleep quickly, but let the sleep condition has been stuck in the light sleep period, it is difficult to enter the deep sleep period. Therefore, people who drink alcohol, even if they sleep for a long time, will still wake up feeling tired. Some foods have a hypnotic effect and can be consumed regularly to improve sleep. Milk has two types of hypnotic substances. One is L tryptophan, a raw material that can promote the synthesis of sleep serotonin. Because of the role of L tryptophan, it often takes only one glass of milk to make peptides with regulatory effects, including several “opioid peptides”, which can bind to opioid peptide receptors in the central or peripheral nerves, producing a feeling of euphoria and facilitating sleep. Millet is rich in tryptophan. Tryptophan can promote brain cells to secrete a neurotransmitter pentothal, which makes the brain activity temporarily inhibited, so that people can easily fall asleep. Sunflower seeds contain linoleic acid, a variety of amino acids and vitamins and other nutritional substances, can regulate the normal metabolism of human brain cells, improve the function of the nerve center.
