If you feel cold, cold, sneezing and runny nose, you can fill a thermos bottle and go to bed, and put the thermos bottle half a foot away from your back, which is near the upper part of your back and neck, that is, between Shu Fei point and Dazhui point.

Lying like this for a while will make you sweat slightly, the meridians will be unobstructed, and cold pathogens will be discharged. Need to be reminded that before this, it is best to drink some porridge, and it is better to sweat with food in your stomach, otherwise you can't sweat on an empty stomach.

Method 2: hair dryer warming method

When you catch a cold, you may not have any medicinal materials at hand. At this time, you can use things around you to warm your back, such as a hair dryer.

Specifically, first put a towel on the back of the neck, close to Dazhui point. Dazhui point is easy to find, that is, when we bow our heads, we press the back of our neck with our hands, and the most prominent bone is the location of Dazhui point.

Spread the towel near Dazhui point, then turn on the hair dryer and let the warm air blow the towel continuously. At this time, the hair dryer should move up and down slowly along the Du meridian, and don't always concentrate on one point to avoid burns. You will soon feel the heat and warm your body. After a while, you will sweat a little, so that the cold evil will be expelled a little.
