Sleep Data

Former Member over 5 years ago

I am using the Forerunner 30. Worn it for the past 3 nights and the first 2 it seems to have monitored my sleep fine. Last night though there is no data. I wore my watch in the same position and it does have heart rate data throughout the night, so why would this be?

Hard to tell, it could be due to a number of reasons - for example low battery, bad fit, periferal vasoconstriction, malfunction, cardiac arrest :-) .... Try restarting the watch, charging, assuring the fit is all rigth for deteting the HR, and you'll see whether it helps.
