Meditation and mindfulness

Thetamask guides your brain into the same slow frequencies long-term meditators reach. This can greatly improve depth of meditation in a short amount of time, even for beginners.

Most sleep tools interfere with the body’s natural processes.

We focus on: Supporting your body's natural relaxation processes.

Audiovisual entrainment doesn't force relaxation, it creates the conditions where your brain naturally wants to wind down. Research suggests that rhythmic light and sound pulses can guide the brain toward the slower frequencies associated with deep relaxation and sleep onset. No willpower required, and no known side-effects.

02

Feel the shift.

The light and sound pulses sync with your brain's natural frequencies. Your brainwaves begin to slow. You don't have to do anything.

03

Drift.

Theta rhythms deepen your relaxation. You dissociate from your regular stressful life, and you slowly feel a shift towards a drowsy and resting state.
