Hello,
I am looking for something (on sale, preferrably :) ) that can help me monitor my heart rate when I sleep.
Looks like a fitbit type of a wrist band is the way to go.
I have never worn a wrist band. It appears the tightness of the band can effect the results it reports ?
What have people used to measure heart rate at night ? Any pros and cons of any devices ? What do you recommend ?
Cheers,
Out of the blue but why do you need to track your heart rate when you sleep ?
