The thought of having small electric currents sent through your mid section might be a little uncomfortable to some. This raises the question about whether ab belts are safe or not.
The FDA in the United States has cleared several EMS belt manufacturers for safety with some devices (such as The Flex Belt) being cleared as a Class II Medical device.
This “clearing” basically means that these devices do not pose a serious risk to harm those who are using them as directed. An important point there is as directed. If you decide to wrap your ab belt around your head, then I’m guessing there will be some serious side effects. So stick to using the device around your core muscles as it is designed to do.
Women who have recently given birth should be sure to check with their family doctor prior to using any EMS device. Also those who have a history of stomach, abdominal or other internal conditions should probably steer clear as well.
Over all, ab belts are safe, and EMS technology is used around the world every day by pro athletes and physical therapists. The key is ensuring you’re using the device as it was intended to be used.
