Drinking to warm up is actually unscientific. You will feel feverish after drinking it. This is because alcohol stimulates epidermal capillaries and accelerates blood flow, but the blood stored in human liver will also flow to the body surface, and the warmth is only temporary; In the past, a lot of heat energy stored in the body will radiate to the outside, and the body's ability to keep out the cold will decrease, which is easy to cause "wine cold". To be warm, you can use diet therapy and traditional Chinese medicine, such as: lotus root, nourishing yin and clearing heat, moistening dryness and relieving cough, clearing heart and calming nerves; Ginseng, invigorating qi, invigorating spleen, benefiting lung, calming heart and improving intelligence.
