Versa 3 stopped tracking my sleep data while I'm on a moving boat

Sleep tracker not working while I am on a moving boat. Does this affect ability to determine if I’m sleeping? Since I’ve been on the boat, the sleep tracker does not register sleep. I have googled and tried all Fixes mentioned online.

Hi there, @SunsetRunner. Welcome to the Community Forums. Thanks for trying to troubleshoot this inconvenience before posting here. 

Please note that your sleep data is measured by your heart rate readings and heart rate readings may be affected by several factors such as air temperature, stress level, alcohol or caffeine intake, immune response to illness, and medication use (source).

Cold weather can make it more difficult for your device to track your heart rate, as environmental conditions can affect skin perfusion (the amount of blood that flows through your skin).

Spikes in your heart rate during sleep may be caused by sudden movements (for example, waking up and getting out of bed), or a weak signal due to wrist placement.

Review our tips in How do I improve the accuracy of a heart-rate reading? and What should I know about Fitbit sleep stages?

Hope that helps.

Thank you for your prompt response! Reviewing the many factors you listed and none seem particularly relevant to my situation. I’ve used the tracker for months nightly, but since vacationing on a boat, near my home, the tracker does not register my sleep time. Once again, I asked the question because we are on a mooring that swings back-and-forth and I’m wondering if my Fitbit doesn’t realize that I’m sleeping and thinks I’m moving. Last night, prior to sleeping, I rebooted my Fitbit app, and my Fitbit watch, and this morning, still no data. I am wearing the watch in the same manner I do nightly, and nothing particularly has changed with my personal health metrics. Any thoughts? This question must not come up very often!
