What Happens While You Sleep
When you sleep, your body does big work — growing, healing, and storing memories. Sleep apps and smart watches use sensors to figure out how deep and steady your sleep was.
AI looks at your patterns over many nights. It might suggest going to bed a little earlier, or staying off screens before bed, based on what helps you sleep best.
What sleep AI tracks
- How long you slept
- How deep your sleep was
- Times you woke up
- What helped you fall asleep faster
The big idea: sleep AI helps you spot what gives you good nights — but the only way to know is to try.
