It is good to drink some milk before going to bed. Milk can sleep well; Still dry red, dry red can soften cardiovascular and cerebrovascular diseases, which is very good for middle-aged and elderly people, but don't drink too much, a small cup is enough! But avoid drinking dry red milk! Wake up in the morning and drink light salt water! It has many advantages. If the human body sweats a lot, some sodium ions and potassium ions in the body can be lost, leading to hyponatremia or hypokalemia. This requires supplementing sodium and potassium, usually by drinking more light salt water and foods and drinks with high potassium content. However, many people only drink some salty boiled water after sweating, even if they have symptoms of sodium deficiency such as fatigue, dry mouth, dizziness, muscle pain, numbness of hands and feet. This kind of passive sodium supplementation slows down the metabolism in the body and increases the burden on the kidneys, which often fails to play its due role. There is a folk proverb, drink salt soup as ginseng soup in the morning and arsenic at night. So drink light salt water early and drink some milk or dry red before going to bed at night! You might as well try!
