Roasting is generally not recommended for more than 15 days, because these roasting-type physical therapy sessions are 10-15 days, and usually a pause is required after doing enough sessions, commonly 3-5 days, and the local soft tissues must be given proper rest before continuing with the second session. If you do not stop baking for a long time, it is easy for the local soft tissues to undergo frequent stimulation and degeneration or damage, which may have adverse effects. When baking electricity in general, care should be taken to avoid getting too close to the skin, and the distance must be adjusted according to your skin’s ability to tolerate heat. If you accidentally get too close to the skin and cause a skin burn, you must immediately stop treatment and then give the wound strict disinfection and topical application of some burn cream to care for the wound.
