Zeus uses gentle electrical stimulation (TENS technology) to keep your airways open while you sleep. The device is placed under your chin and works by activating the tongue and throat muscles, preventing them from relaxing and causing snoring.
This technology was developed in collaboration with leading sleep experts at King’s College London and Guy’s & St Thomas’ NHS Foundation Trust in the UK.

Tongue-based snoring often occurs when the tongue relaxes too much, especially when sleeping on your back. Individuals with a larger tongue may be more prone to this type of snoring. Throat-based snoring can happen in any sleeping position and may cause loud snoring, frequent awakenings, or waking up with a dry mouth. If you're unsure what type of snorer you are, you can take an interactive snore test or speak to your doctor for advice.

Zeus is designed to be worn unnoticed, unlike other snoring solutions. Unlike mouthguards, mouth tapes or nasal strips, Zeus does not require you to wear anything in your mouth or on your nose. It is a non-invasive, clinically-proven solution that targets the root cause of snoring – the relaxation of tongue and throat muscles. The result is a comfortable, discreet, and more effective solution, backed by 15 years of research and development.

Yes, Zeus is designed for comfort. Our mission with the Zeus device is for it to be worn unnoticed as most other snoring solutions are invasive or uncomfortable. It is made from medical-grade silicone and secured with gentle, skin-friendly hydrogel pads. The device is lightweight, compact, and easy to use, allowing for unobtrusive, comfortable wear throughout the night.

Zeus is specifically designed for individuals who experience tongue-based or throat-based snoring. If your snoring is caused by the relaxation of your tongue or throat muscles during sleep, Zeus may be an effective solution for you.

However, Zeus is not effective for snoring caused by blocked nasal passages, allergies, or congestion. If you are unsure about the cause of your snoring, we recommend consulting your doctor or a sleep specialist.

Yes, the hydrogel pads are essential for the proper functioning of the Zeus device. They ensure a secure and comfortable fit while also conducting gentle electrical stimulation to your muscles. Each Zeus device comes with a 30-day supply of medical-grade hydrogel pads. We also offer a subscription service to receive fresh hydrogel pads every 30 or 90 days, so you can enjoy uninterrupted, snore-free sleep.

Yes, Zeus gets to work right awayfor those experiencing tongue or throat-based snoring. As soon as you switch it on, the TENS technology begins stimulating the tongue muscle. This prevents the tongue from collapsing toward the back of your throat, helping to stop snoring from the very first use.

The Zeus device uses TENS (transcutaneous electrical nerve stimulation) technology, which has been clinically tested in two independent trials — the TESLA and TESLA Home studies. These trials showed promising results for people with mild to moderate Obstructive Sleep Apnoea (OSA). 

While Zeus is not currently a certified treatment for OSA, the technology behind it has been shown to support airway stability during sleep, which may help reduce symptoms in some individuals. 

If you’ve been diagnosed with OSA or have concerns about your sleep health, we always recommend speaking with a medical professional before starting any new treatment

Zeus is designed to help with snoring caused by the tongue or throat. However, it’s not suitable for everyone. You should not use Zeus if any of the following apply to you: 

• You suffer from nasal snoring (Zeus is only effective for tongue/throat snoring). 
• You have long facial hair under the chin (short stubble is fine, but longer beards may prevent proper adhesion). 
• You have metal implants in the head or neck (this does not include dental fillings). 
• You have a pacemaker or suffer from heart arrhythmias.  

You have been diagnosed with any of the following: 

• Deep Vein Thrombosis (DVT). 
• Cancer, particularly near where the device would be applied. 
• Epilepsy, seizures, alcoholism, or leprosy.  

You are recovering from surgery, especially near the chin area (do not use over scars for at least 10 months after surgery). 

You are using other medical devices such as: 

• TENS machines. 
• ECGs. 
• MRI scanners. 
• Other electronic diagnostic tools. 
• You are pregnant. 
• You are under 18 years old.

Our device has been validated through three independent clinical trials; the Dorset Trial, the TESLA Trial, and the TESLA Home Trial – conducted in partnership with leading universities and NHS Trusts. Every step of development is backed by rigorous research, from early scientific discovery to large-scale clinical testing. Zeus is a clinically proven solution to reduce snoring and improve sleep quality. If you would like to learn more about clinical evidence, see here.
