Do you need to wear clothes to dry your back in the dog days?

It is recommended not to wear clothes, because it is better to wear clothes, but you can also wear clothes, mainly depending on the individual. Sun-drying the back is a way of keeping in good health in traditional Chinese medicine, and dog days can enhance immunity. The dog days, which appear between the summer heat and the summer heat, are the period with the highest temperature, the highest humidity and the most severe sultry heat in a year.

Three volts can be divided into initial volts, intermediate volts and final volts, and their dates are determined by the coordination of solar terms and solar terms in the dry branch calendar.

After lodging, the surface humidity increases, and the heat absorbed every day is more, but the heat emitted is less, and the heat on the surface is accumulated. So it gets hotter every day, and when it enters the dog days, the accumulated heat on the ground reaches its peak and the weather is the hottest.

The length of the dog days mainly lies in the difference of midsummer, because the third Geng day (early summer) after the summer solar terms appears at different times every year, so the number of midsummer days is also different. The days in midsummer are long and short, which may be 10 days or 20 days.
