The SnooZeal product consists of a mouth piece that places electrodes above and below the tongue, a control unit that connects to the mouthpiece, a remote control, and a smartphone app. It works by electrically stimulating the tongue to give it a workout and keep it from completely relaxing and collapsing during the night. Snoozeal Inc. is a company out of Seattle, Washington that won the European CE Mark for its snoring prevention device.
The SnooZeal is not actually used during sleep, but indicated to be placed in the mouth twice a day for a period of six weeks. This essentially physically trains the tongue muscle and helps to keep it at least partially contracted even at night.
The device can be controlled either via the remote or through the accompanying smartphone app.
Results from multiple previous clinical trials have proven that muscle activity can be improved with this electrical stimulation technology principle.
Several studies have shown that electrical stimulation of the tongue can reduce snoring and sleep-related obstructions.
SnooZeal is the first patented product that is used entirely in the mouth and that directly stimulates the tongue muscle in order to address the root cause of snoring.
