Never drink milk alone. Milk is cold and will accumulate in the body, which is not good for your health. People who drink milk like this for a long time will become depressed. Maybe you haven't noticed, but it's true. Cold in the body can lead to menstrual abdominal pain. Especially in winter, when the weather is cold, it is easier to catch a cold. You can use moxa sticks to smoke at the 4 fingers below the umbilicus (the specific usage can be found on Baidu). Of course, if you like drinking milk very much, you might as well drink some ginger milk, which can not only supplement calcium, but also help you drive away the cold, so it won't hurt in the future. Anyway, if you want to drink milk, you have to eat something warm to adjust your balance.
