Frequently Asked Questions


Snoring is caused by vibration of the structures of the throat during sleep.  When you sleep, the muscles of the throat relax and partially collapse. The narrowest parts of the throat can then create turbulence of the air flowing through your throat which makes the snoring sound

You’re more likely to snore if you:

  • are overweight
  • smoke
  • drink too much alcohol
  • sleep on your back

It has been shown that snoring affects sleep quality of the snorer and partner.

It is important to note that snoring may just be the tip of the iceberg. Although snoring per se does not damage your health, snoring can be a clue to a more serious condition called obstructive sleep apnoea (intermittent complete blockage of breathing during sleep).

Sleep apnoea is a serious health condition associated with health problems like high blood pressure and increased risks of heart attack, stroke, or death. It is often associated with day time sleepiness and your partner may notice you breath hold or stop breathing in the night.

If you have these symptoms or are concerned you may have the condition, please refer to your doctor.

Simple lifestyle changes can help to reduce snoring:

  • try to lose weight if you’re overweight
  • don’t smoke
  • reduce or avoid alcohol

Unfortunately, despite these measures, you may still snore and will need to explore other options. eXciteOSA® has been clinically proven to reduce snoring and sleep apneoea significantly, when used for 20 minutes, 1 time each day for 6 weeks.

Continuing to use your eXciteOSA® after the initial 4-6-week therapy, will help keep your tongue muscle toned sufficiently and your snoring controlled.  Like any other muscle in the body, to keep it toned, regular conditioning is required once a week for 20 minutes as a maintenance therapy.

Your eXciteOSA® box includes:

  • Control unit
  • Mouthpiece
  • USB charging cable
  • Charger
  • User instructions

The eXciteOSA® device will deliver small electric currents through the mouthpiece to your tongue, this will stimulate the tongue muscle and improve its tone. The improved tone of the tongue muscle will help in keeping the breathing passage open during your sleep and reduce the vibration of the throat region.

The eXciteOSA® can be used at any time during the day, but it is recommended to be used before you go to sleep at night.

The intensity always starts at level 1. It is recommended that you increase the intensity to a level that is comfortable for you for each therapy session.

Over the duration of the recommended therapy programme you will notice that your tolerance levels will increase, and you can go up in intensity comfortably. It is important to avoid increasing the intensity to beyond comfortable level, as higher intensity will not lead to additional improvement.

The mouthpiece is made from flexible silicone which should sit of your tongue comfortably. If you get any discomfort, reposition the mouthpiece into a comfortable position. Like any other object when placed in the mouth, you might experience a gag reflex or increased saliva in your mouth initially.

The mouthpiece is connected to the control unit through the USB connector and port. The mouthpiece is then placed onto the mouth above and below the tongue. Two flanges of the mouthpiece should sit comfortably above and two below – like a glove. Please don’t bite down on the mouthpiece as that may damage the device and is not necessary to hold the device in position. The mouthpiece is designed such that when you gently close your mouth, it will naturally sit around your tongue and won’t move through the therapy period.

The control unit is charged through the USB port using a USB charging cable. The USB is connected to the supplied power plug and connected to the mains supply. The blue light of the control unit will blink during charging and become continuous when fully charged.

When the therapy is running the timer on the App will tick down. Additionally, the blue LED on the control unit will blink once every 5 seconds.

On one full charge, you should be able to run six 20-minute therapies. The App won’t allow you to start a new therapy unless there is adequate charge within the control unit to complete a full therapy session.

During the therapy you should experience a tingling sensation on the tongue and tongue muscle contractions. As the intensity is increased the muscle contraction will get stronger.

Increases the intensity until you feel contractions of the tongue with the stimulus. The intensity should be increased to the maximum tolerable level. This is very similar to CPAP- you need pressures that ensures you overcome the collapse without giving too many side effects.

Increasing the intensity beyond a tolerable level will not improve the outcome of the therapy session but may become an uncomfortable sensation.

No, do not use the device during sleep. The eXciteOSA® device is to be used during the day, awake times only. If possible, it is recommended for the therapy to be administered before going to sleep.

It is not recommended to run two therapies one after another. When you finish your therapy session, you will have to wait 30 mins before starting a second session.

You should notice an improvement in your snoring within 4 weeks. This is dependent upon adherence to the recommended therapy programme of one 20-minute session daily. Although you may see improvement within 4 weeks, we recommend you finish the 6-week therapy period to ensure you gain the optimal improvement possible.

The eXciteOSA® App offers full remote-control functionality of the eXciteOSA® device.
