The prescription-strength sleep aid

Proven in multiple published studies, Circadia increases total sleep time in the majority of patients. Simply use the device at home for 20 minutes before bed every night. Return it for a full refund within 30 days if you aren't sleeping significantly better.

The brain is an electrical system

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

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

Manufactured by Fisher Wallace Labs, Circadia is technologically identical to the FDA-cleared Fisher Wallace Stimulator, but may be purchased without a prescription.

The majority of people who use our technology want to avoid the side effects of sleeping medication.

About Fisher Wallace Labs

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.
