If it is to improve the patient’s sleep, it is recommended to drink pure milk, because pure milk contains a higher content of tryptophan, which has a certain sedative and hypnotic effect on the cerebral cortex, so it can improve sleep. If it is milk with fat or added sugar components, the protein content is not as high as pure milk and there will be a lot of sugar substances, which will increase the burden of metabolism in the patient’s body. If this milk is consumed for a long time, it is not good for improving sleep and may cause the patient to gain weight. In addition to drinking milk to improve sleep, you can also eat millet porridge, which contains more tryptophan and can also improve sleep, and can also adjust the spleen and stomach. Some medicinal foods can also be used, such as lily, dates, longan meat, also have the effect of sleeping.
