Sea-Band is a knitted elasticated wrist band, which operates by applying pressure on the Nei Kuan acupressure point on each wrist by means of a plastic stud. Because the bands do not use drugs, they do not cause any of the side effects associated with anti-nausea drugs and can be worn on each wrist whenever you feel nauseous. They are suitable for adults and children. Sea-Bands may be used to relieve motion sickness, morning sickness and cancer nausea and vomiting. To ensure your Sea-Bands work properly, please follow the instructions below to position your wristbands correctly. - Place your middle three fingers on the inside of your wrist with the edge of the third finger on the wrist crease. The Nei-Kuan point is just under the edge of your index finger between the two central tendons. - Position the button facing downward over the Nei-Kuan point. Repeat the process for the other wrist. - One band must be worn on each wrist to be effective. Sea-Bands can be put onto your wrist before you start travelling, or after you have started your journey.
