Why does my alarm ring early today?
It is a smart alarm.
This alarm picks an easier wake time.
I set it for seven.
It checks my small moves in bed.
Small moves can mean light sleep.
During light sleep, we wake more easily.
Then, the alarm rings near seven.
I open my eyes and sit up.
But here is the important part.
The alarm only makes a good guess.
It cannot truly know my sleep.
So, I still need enough sleep.
A smart alarm may help.
Good mornings start the night before.
