Health for All says
First of all, tanning the back belongs to a kind of Tianjiu**, which is the same as acupuncture, moxibustion, etc., and belongs to the uniqueness of traditional Chinese medicine**. The principle of sunbathing is to stimulate the acupuncture points of the human body and adjust the flow of qi and blood through the irradiation of sunlight, so as to achieve the effect of replenishing yang and dissipating cold. In the theory of traditional Chinese medicine, yang qi is one of the basic elements of the human body, and sufficient yang qi can maintain the normal physiological functions of the human body. Cold evil is one of the root causes of human diseases, and excessive cold in the body will lead to yin and yang imbalance, which will lead to various health problems. As a kind of traditional Chinese medicine, it is the use of the warm and warm characteristics of sunlight to dispel the cold in the body and achieve the purpose of adjusting the balance of yin and yang in the human body.
Secondly, to properly tan your back**, you need to pay attention to the following points. First, choose the right time. Dog days are warm and sunny, making this the best time to get a sunbath. Generally speaking, 9 to 11 a.m. and 4 p.m. to 6 p.m. are times when the sun is softer and suitable for sunbathing**. Second, choose the right location. It is best to choose a place with good air circulation and direct sunlight, such as natural meadows, sandy beaches, etc. At the same time, make sure that the position of the sun is exposed to the sun so that the sunlight can fully reach the acupuncture points on the back. Finally, the time of sunbathing should also be well controlled, generally speaking, the time of each back sunbath should not exceed 20 minutes to avoid injury from long-term exposure to the sun.
In addition to the above considerations, there are some situations that need special attention. First of all, it is not suitable for younger and weaker people, such as infants, pregnant women and the elderly, because they are more fragile and prone to injury. Secondly, people with broken and scarred bones are also not suitable for sunburning, so as not to cause infection or aggravate the wound. Finally, for people with heat illness in the body, as well as people with high yang energy, back tanning may not be suitable or need to be carried out under the guidance of a doctor.
In recent years, a growing body of scientific research has confirmed the benefits of back tanning. For example, one study found that sun exposure not only boosted the body's immunity, but also increased antioxidant capacity and reduced inflammation. In addition, sunbathing also helps to increase vitamin D levels in the body, promoting calcium absorption and bone health. However, more research is needed to further validate these findings and to delve into the impact of back exposure on other health problems.
To sum up, as a traditional Chinese medicine**, tanning has the effect of replenishing yang and dissipating cold, which can help people stay healthy. When sunbathing**, you need to pay attention to choosing the right time and place, control the time of sunbathing, and avoid injuries caused by prolonged exposure to the sun. In addition, certain populations, such as infants, pregnant women, and the elderly, as well as people with thermal illnesses, need to be cautious about sunbathing**. Despite the benefits of sunburning, more scientific research is needed to further validate and ** its mechanism of action.
