Prescription-strength stress & sleep management

Proven in multiple published studies, Circadia is a neuromodulation device that has been shown to reduce cortisol (the stress hormone) and improve sleep quality when used for 20 minutes, once or twice a day. Over 40% of customers also report significant improvement in cognitive performance (focus, concentration, memory). Try Circadia with the confidence of our 30-day free return policy.

Powerful relief, simple to use

Circadia is a groundbreaking innovation in wearables. Manufactured by Fisher Wallace Labs, the device is technologically identical to the FDA-Cleared Fisher Wallace Stimulator, but may be purchased without a prescription.

After a 20-minute morning session, users typically feel more relaxed and are able to concentrate for many hours later. When used for 20 minutes before bed, the session prepares the brain for a restful night’s sleep.

Over 100,000 people have used Fisher Wallace’s technology, which causes no serious side effects and can be used in conjunction with medication.

Evidence-based technology

In a study conducted during the pandemic, our technology increased total sleep time (TST) in active device participants by 25.8 minutes, whereas participants using a placebo device experienced a decrease in total sleep time of 16.5 minutes - a total difference between active and placebo of 42.4 minutes. Our published biomarker research demonstrates that our technology increases serotonin and lowers cortisol.

I have had great success using the device to treat patients who are resistant to pharmacotherapy. Also, patients who seek a drug-free alternative have used the stimulator to reduce or eliminate their dependence on drugs.
