Is frequent use of sauna good for the body?

　　Sauna is a bathing method based on "steaming and roasting". In a sealed cabin of several square meters, the temperature can reach as low as 60 or 70 degrees Celsius. The charm of this fashionable Western bathing method is that after the skin of the whole body has withstood the "torture" of high temperature, it can obtain a relaxing pleasure after the torture. Mr. Chen, 30, has recently become obsessed with saunas.

　　When he entered through the "oven" door that was so narrow that he could only pass by leaning sideways and lowering his head, a wave of hot air hit his face. After a while, all the pores in his body opened, and the high temperature penetrated skin Penetrating into the muscles and bones of the body, the testicles in the scrotum are unbearably hot. However, the human body does not take into account the painful feeling of the testicles, and continues to "steam and bake" blindly, causing the scrotum to fail to adjust. The temperature in the scrotum continues to rise, and the testicles are slowly numbed by the high temperature.
