Dog days, the hottest time of the year, enter the dog days every year, and the "sun on the back" regimen has become a hot topic again.
Recently, a woman in Foshan, Guangdong Province posted that she lost 4 pounds after drying her back on the roof for 10 days, and said that she felt that her eyes had become clear after half an hour of drying every day. Subsequently, "losing 4 pounds in 10 days on the back" rushed to the hot search, and a wave of "sun-to-back" was set off on the Internet.
What are the benefits of dog day sunbathing?
Dog days actually have a certain theoretical basis in traditional Chinese medicine. Traditional Chinese medicine believes that the principle of "dog days" is similar to that of "dog patches", which is to stimulate the meridian acupuncture points to achieve the effect of replenishing yang qi and enhancing immunity.
The back meridians are mostly yang meridians, and the dog days can stimulate the yang energy of the meridians and have a certain health care effect. In addition, sunbathing can also help tonify the kidneys, promote calcium absorption, improve blood circulation, improve sleep quality and other benefits. However, sunbathing does not help with weight loss and does not burn fat.
Most of the people who are suitable for back health are people with cold constitution, such as: fear of wind, cold, easy to catch colds repeatedly, joint pain in case of cold, deficiency of cold in the body, easy diarrhea, etc. Although tanning is a beneficial way for many people to maintain their health, it is not suitable for everyone.
Who is not suitable for back tanning?
1. People who are allergic to ultraviolet rays. These people are particularly sensitive to ultraviolet rays in the sun, and sunbathing their backs may trigger allergic reactions;
2. People with strong physique and yang energy or yin deficiency and hyperyang. Traditional Chinese medicine pays attention to the balance of yin and yang, and only those who lack need to be filled. People with strong yang energy do not need to sun their backs to maintain their health, but because they are prone to fire, sore throat, and constipation, these symptoms may be aggravated if they are sunburned;
3. People with low immunity. For example, pregnant women, infants and young children, people with underlying diseases, especially patients with hypertension and coronary heart disease, do not need to deliberately bask their backs, just bask in the sun normally.
You can't blindly follow the trend of back health, and these are the particulars:
1. When and to what extent?
Dog days can be done after 7:00~9:00 or 15:00, during which the sun will not be too fierce, and it is not necessary to dry every day. If you sweat excessively and are accompanied by uncomfortable symptoms such as increased body temperature, weakness of limbs, dizziness, thirst, headache, etc., you should consider the possibility of heat stroke and seek medical attention in time.
2. How long does it take to sun your back?
Adults should bask their backs for 15~30 minutes each time; As the elderly age, their ability to synthesize vitamins decreases, and the time of sunbathing can be appropriately extended. But don't be exposed to the sun for too long, just sweat slightly. Children have delicate skin, and it is recommended not to exceed 15 minutes depending on individual differences.
3. What else should I pay attention to?
It is recommended to wear light-colored, thin, loose-fitting clothes when drying your back; At the same time, we must take sunscreen and heatstroke prevention measures, especially pay attention to the head, face, eyes and other parts to avoid sunburn. Do not sun your back on an empty stomach, drink boiled water or light salt water in moderation before and after the sun to replenish body fluid consumption.
If you have eaten photosensitive foods, such as amaranth, celery, rape, spinach, lemon, grapefruit, etc., do not bask in the sun, otherwise it is easy to cause solar dermatitis.
After drying your back, you should change your sweaty clothes in time, and turn on the air conditioner or take a shower when you don't sweat anymore.
While enjoying the health benefits of the sun, we should also pay attention to our physical condition and weather changes, and arrange the time and method of sunbathing reasonably to ensure that it is safe and effective. If you experience itching or pain in the skin, you should stop doing it immediately, and seek medical attention if you have any symptoms of heatstroke.
