Fall Asleep Faster.
Wake Up Better.

Empower your circadian, wake more naturally, and care for your sleep hygiene like never before.

Sleep Mask Product

Humanity's habits have modernized, our approach to sleep hasn't.

We're living in a world of screens, blue light, and schedules our biology wasn't evolved to live around. Our ancestors weren't exposed to artificial light, 24/7 connectivity, or modern constant stimulation, yet we still try to sleep like they did. The world has changed drastically, but sleep hygiene hasn't.

Take control of your sleep

Rhythm is used to enhance your sleep with a combination of light therapy protocols, built for your body and its circadian rhythm.

Blue Light Therapy

Cues your body to stop melatonin production and naturally wake up, boosting morning alertness.

Blue Light Therapy

Red Light Therapy

Stimulates melatonin production at night, reduces morning grogginess, and supports recovery from eye strain.

Red Light Therapy

Pulse Therapy

Shifts circadian rhythm forwards or backwards for multiple hours with less than a second of total light exposure during your sleep.

Pulse Therapy

Smart Waking

Subtly nudges your circadian rhythm before your scheduled wake-up, making mornings smoother. Rhythm helps you reduce cycle drift, improving your morning wakeup.

Smart Waking

Smart Alarm

Combines light therapies for a silent, natural wake-up. Blue light boosts alertness; red light eases grogginess.

Sleep Better, Live Happier

Rhythm's benefits show up in more than just the hours you're asleep.

Fall asleep quicker

Sitting in bed for hours before you fall asleep? Our optimized waking algorithm helps you reduce unwanted sleep-wake cycle shifts, allowing you to drift off faster.

Wake up energized

Cold-starting from deep sleep leaves you feeling groggy. Our wake-up sequence gently stimulates your brain before your alarm, helping you feel energized by the time you wake up.

Sleep anywhere

Thanks to silent light-based wake-ups and easy integration with headphones or earplugs, you can rest without disturbing others or being disturbed by them.

Be ready for any schedule

Need to change your morning wakeup? Instead of struggling to snooze earlier or risking a day of sleep deprivation, Rhythm uses light to help you move your circadian while you're asleep.

Frequently Asked Questions

Sound-based alarms trigger a defensive reflex—jolting you awake. This can lead to grogginess while also disrupting others around you. Rhythm wakes you with light, your body's primary waking cue. When light hits your eyes, it signals your brain to stop melatonin production and increase cortisol.

Rhythm helps you regulate your sleep-wake cycle and optimize waking up and sleeping processes. Combined with the ability to use earplugs, users can get the best possible sleep hygiene in any environment.

Yes, Rhythm is designed to be easily cleaned. The mask is removable and washable, separate from the electronics.

Absolutely. By helping you shift your circadian rhythm, Rhythm can be a powerful tool in combating jet lag. You can set it to help your body acclimate to a new time zone more quickly.

Rhythm was partially inspired by experiences with roommates. It's designed to improve shared environments by not disturbing others with noise or light. If your roommate often wakes you up, we recommend using Rhythm with earplugs to create a perfectly isolated sleep experience.
