Can a tiny ring watch your sleep?
It cannot see your dreams.
But it can check your body.
This is a smart ring.
It checks movement while you sleep.
It checks how fast your heart beats.
Mika wears one before bed.
In the morning, her phone shows sleep time.
She slept less than usual.
Then, she remembers her late coffee.
Next evening, she drinks water instead.
The ring can help her see changes.
But it is not a doctor.
Its answer may not be perfect.
Still, a small ring asks a big question:
What helps you sleep well?
