Acupressure slippers use targeted pressure points to stimulate blood flow and relieve discomfort. They come in various designs, such as general relaxation, sleeping aid, and circulation booster. Duration of wear depends on individual goals and needs, starting with 15-20 minutes for first-time wearers. As the body adapts, sessions can be extended up to an hour or more for better results. Safety considerations include using only as directed and listening to one's body, respecting comfort limits and avoiding aggravating existing conditions. Consistent application and responsible usage are essential to achieving relaxation and relief from various discomforts.
