After gua sha, it is generally advisable to wait about one week before taking a bath. This is because the skin and mucous membranes are often damaged during the scraping process, and bathing too early may allow pathogens to enter, leading to infectious skin inflammation. Gua sha helps unblock meridians and alleviate symptoms of swelling and pain caused by poor blood circulation. However, after the procedure, it's important to keep the body warm and avoid catching a cold.
