Firstly it's important to note that the vast majority of people use Modius without any side effects whatsoever, and most find the stimulation provided by the headset to be a relaxing experience.

The vestibular system gets stimulated naturally during many everyday activities such as skipping, jumping, trampolining etc. Even the action of rocking a baby to sleep is vestibular stimulation. Modius is delivering stimulation of the vestibular system by a pulsing to the area behind the ears where the vestibular nerve runs through to the hypothalamus.

Interestingly, this recent research paper indicates that Modius can actually help with the management of tension headaches.

However, everyone is different in their sensitivity to vestibular stimulation so you may find you are only able to tolerate the pulsing at a low level, particularly if you are susceptible to motion sickness. There are 10 power levels with the Modius headset, so to avoid any side effects we recommend the following:

Start out slowly at power level 1 (no higher than level 3) for your first few sessions as it will take your body time to get used to the stimulation. As your body becomes accustomed to it, you will slowly be able to increase through the power levels - but only if you feel comfortable to do so.

Make sure you only use the headset when you are sitting down as the vestibular system is associated with balance in the body.

Ensure you increase your fluid intake - many users report feeling more thirsty when they start to use Modius.

If you feel uncomfortably nauseous, dizzy or have a headache, discontinue use for a few days and only start back using your headset again when any symptoms have subsided, and only as and when you feel ready. Again, we recommend starting at level 1 and only increase the level over time if you are not experiencing any side effects. If you are concerned at all, we recommend checking with your doctor.

Should you experience any skin irritation from the pads, we would advise discontinuing use until any inflammation has settled. The application of aloe vera gel will sooth the skin. The irritation may be coming from the alcohol cleansing wipes, so you can use soap and water to gently cleanse the area before applying pads instead of the wipes.
