You set three alarms. You slept through all of them. Again. If that sounds familiar, here's the good news: it's not laziness, and it's not just you. It's how your brain is wired.
Your brain learns to ignore your alarm
The brain is brilliant at tuning out repeated, predictable sounds — a survival feature called habituation. The same alarm tone, every morning, quickly becomes background noise your sleeping brain files under “safe to ignore.” Add the snooze button, and you actively train yourself to sleep through it. Studies suggest most people hit snooze regularly, and a large share set three or more alarms just to hedge against oversleeping.
Louder isn't the answer
Turning the volume up wakes everyone else in the house before it reliably wakes a deep sleeper — and it still fades into habituation over time. That's why the “bomb”-style alarm clocks work for a week and then stop.
Touch is harder to ignore than sound
Vibration on your wrist is a different kind of signal — direct, physical, and much harder for a sleeping brain to file away. A gentle buzz that escalates in intensity keeps building until you're actually awake, without a single decibel of sound. That's the entire idea behind Rouzu: a slim, screen-free band that wakes you through your wrist instead of the whole room.
The simple switch
If you've tried every alarm tone and still oversleep, the fix usually isn't more noise — it's a different sense. Wake to touch, keep your phone out of the bed, and give your brain a signal it hasn't learned to ignore.
