The prescription-strength stress & sleep aid

Proven in multiple published studies, Circadia is a neuromodulation device that can help stabilize mood, reduce stress and improve sleep quality when used for 20 minutes, once or twice a day. Try Circadia with the confidence of our 30-day free return policy.

The brain is an electrical system

Our technology works by treating the brain electrically to help you sleep better.

Manufactured by Fisher Wallace Labs, Circadia is technologically identical to the Fisher Wallace Stimulator, which is FDA-cleared to treat depression, anxiety and insomnia. Circadia is intended for stress and sleep management, so is available for purchase without a prescription.

During each treatment session, the device stimulates the brain to release neurochemicals needed for healthy mood and sleep, reduce cortisol and regulate brainwave activity.

Use the device for 20 minutes in the morning to feel more relaxed, and 20 minutes before bed to prepare the brain for a restful night’s sleep. Over 40% of customers also report significant improvement in cognitive performance (focus, concentration, memory).

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.

Additionally, our published biomarker research demonstrates that our technology increases serotonin and lowers cortisol.
