How long should one wait before taking a shower after gua sha or cupping?

You should wait about five hours after gua sha or cupping before taking a shower. After gua sha or cupping, the pores of the skin in the treated areas are open and there may be subcutaneous bruising. It is important to avoid exposure to wind and cold at this time, so showering immediately is not recommended. Pay attention to covering and protecting the treated areas to prevent catching a chill. Gua sha and cupping are traditional Chinese external therapies that help detoxify the body, regulate meridians, and dispel wind and cold.
