Free 25-second reflex check
Test your deep-sleep reflexes.
💡 Neuroscience fact: deep sleep opens the brain's glymphatic system to flush the day's metabolic waste — and your brain wires repeated bedtime choices into the automatic reflexes that take you there.Xie et al., Science, 2013 · Graybiel, Annu Rev Neurosci, 2008
A 78-second deepsleep game
Each 78 second deepsleep game rewires your reflexes. So you can look forward to sweet deep sleep on autopilot.
How the deepsleep game works
You are asked one real bedtime moment — morning light first, a cool room, screens down — you choose Green Light or Red Light.
The deepsleep game screenshot below shows you are on question 12/12 and have 53 seconds left from your 78 seconds.
You greet the morning light first, and feel your whole mood lift.
What it shows you at the end of each deepsleep game
Every game reads your choices, names what's holding your deep sleep back, and trains the reflex that fixes it — better choices on autopilot, deeper sleep, a better-restored you.
At the end of each deepsleep game (below screenshot), you are shown...
Your daytime-movement, morning-light, and cool-room choices are keeping you from your deepest sleep.
Run it again, knowing your reflexes are being trained to make better choices on autopilot. Your sweet deep sleep awaits.
Run it againThe why
Slow-wave sleep is the stage that clears the brain, repairs the body, and sets you up to wake truly restored — and it's all backed by peer-reviewed research.
Why you need it
DeepSleepGreenLight is a habit-training game that turns the small evening choices governing how deeply you sleep — morning light, a cool room, screens down, early caffeine — into automatic reflexes, so the most restorative sleep arrives on autopilot.
