One study found that acupressure wristbands that stimulate a specific
point on the wrist can help reduce symptoms of
motion sickness such as nausea and vomiting.1
Several brands of bands are available. These bands use pressure,
electricity, or both to stimulate the P6 acupuncture point located about two
finger-widths from the crease on the underside of the wrist. The elastic bands
usually have a raised surface that applies pressure on the wrist. Practitioners
of acupuncture and acupressure believe stimulation of this point may stop
nausea and vomiting.
The bands have no known side effects, so there is no harm in trying
them.
