There is no clear rule that acupuncture should not be applied for more than a few days at a time, but it is determined by the patient’s condition. For acute illnesses, the duration of acupuncture treatment will be relatively short, perhaps 3-5 days. For chronic diseases with a longer duration, the duration of acupuncture treatment is usually longer, such as six months, a year or more. So there is no clear rule on how many days acupuncture should not be used at a time. However, for most diseases, acupuncture is not recommended to be non-stop for one day and treated 7 days a week, usually choosing to take 1-2 days off after 5-7 consecutive treatments and 2 weeks off after 10-15 treatments to avoid too much stimulation from acupuncture, which is not conducive to recovery. After acupuncture treatment, patients should pay attention to more rest, avoid activities, avoid straining, and do not take a bath for 1-2 hours to avoid catching a cold or secondary infection, etc.
