There is a saying among the people: "Basking in the sun in winter is better than drinking ginseng soup." "Everyone knows that sun exposure is good for the body, especially in the cold winter, and it can also warm up the body and be very comfortable. In fact, basking in the sun is also about skills, and if you do it right, you will get twice the result with half the effort.
Recently, the weather in Wuhan has been sunny. According to the doctor, it is best for everyone to seize this opportunity and bask in the sun. Because sun exposure is the most natural way to take care of your health.
Shen Xiaoxia, Department of Traditional Chinese Medicine, Hanzheng Street Community Health Service Center, Qiaokou District: "The benefits of basking in the sun, first of all, are the yang energy in nature. Our bodies are afraid of cold hands and feet in winter. The sun will have an exciting effect on it. Use natural yang energy to trigger yang energy within our body. In addition, the sun's exposure to us will promote the production of vitamins in the human body and promote the absorption of calcium. ”
In addition, winter is the season of high incidence of respiratory diseases such as colds and flu, and ultraviolet rays in sunlight are a "natural disinfectant" that kills many viruses and bacteria and helps prevent diseases. However, although there are many benefits of sun exposure, if you don't master the method well, the effect may be greatly reduced. So, how do we get the sun right? First of all, this "shadow law" should be remembered.
Shen Xiaoxia, Department of Traditional Chinese Medicine, Hanzheng Street Community Health Service Center, Qiaokou District: "There is a very simple trick, which is to look at our shadow. For example, if we stand in the sun and look at a shadow that is about 1:1 compared to a personWhat 5 looks like. At this time, we need to control the time of drying. For example, twenty minutes or so. If the shadow reaches two or even more than three times, this time indicates that the direct point is relatively low, and you can bask in the sun for a while at this time to enjoy the warm winter sun. If it is obviously shorter than yours, it means that the direct sun point is relatively high, at this time we need to go to sun protection, and we also need to control the time, preferably about 15 minutes. ”
In other words, when your shadow is 2 times your height, or even more, the UV index is the safest and you can bask in the sun to your heart's content. If the shadow is within 1 to 2 times the length of your height, it is safest to keep the sun for about 20 minutes. If the shadow is less than half the length of your height, UV rays can damage it within 15 minutes**. In addition, the posture of basking in the sun is also important.
Shen Xiaoxia, Department of Traditional Chinese Medicine, Hanzheng Street Community Health Service Center, Qiaokou District: "First of all, you have to find a comfortable place without tuyeres. Basking in the sun is generally based on the back, and then it is to dry our hands, and now the more popular sun-drying eyes, drying hands is to use your palm, and the more literary saying is the feeling of catching the sun. Basking your eyes is when you slant a little bit and close your eyes, and your eyes are in a red state. When you are sensitive to light in this way, you can adjust the dopamine secretion in the eye, and the photoreceptor cells in the eye will be stimulated to a certain extent, which will protect the vision of the eye. ”
When you are basking in the sun, it is best to choose to be outdoors and not bask in the sun through the glass. Because some studies have shown that through the window glass, the transmission rate of ultraviolet rays in the required band is less than 50%. At the same time, on an empty stomach, within an hour after a meal, it is also not suitable for sun exposure.
Shen Xiaoxia, Department of Traditional Chinese Medicine, Hanzheng Street Community Health Service Center, Qiaokou District: "Under normal circumstances, if you are too hungry or too full, you don't get sun. Those who eat light-sensitive food do not get sunburned. For example, celery, lettuce, and fungus. And then your ** don't bask when you have inflammation. ”
