Traditional Chinese medicine believes that the back is yang and the abdomen is yin, and the yang meridian of the human body is basically distributed in the back, so the spine of the back is the main meridian of yang. The warmth and coldness of the back is closely related to the function of viscera.

Nie Bin said that when cold invades the human body, the back bears the brunt. Cold back can cause backache, muscle twitching and other problems, which may lead to joint and visceral discomfort of lower limbs. On both sides of the back spine are the bladder meridian of Foot Sun, which runs through the whole body. The back Shu points of all zang-fu organs are located in the bladder meridian of the back. Stimulating these acupoints can dredge meridians and qi and blood, tonify Yang Qi, harmonize qi and blood, and restore the function of viscera.

As the saying goes, the sun is warm, and people can only be full of vitality if they have the sun. After entering the dog days, the weather is hot, and many factors, such as blowing air conditioners, eating cold drinks, drinking herbal tea, staying up late and getting up late, damage the yang.

At the same time, summer dampness is also the most harmful to yang. It can be said that in the four seasons of the year, summer is the most vigorous season of human yang, and it is also the most fragile season of human yang. The director of the Department of Acupuncture and Rehabilitation of Guangdong Second Hospital of Traditional Chinese Medicine stressed that not forgetting to help Yang in summer can make people feel comfortable and not disturbed by the cold.
