Hi @sleeperrors2 - I’ve copied info from the Fitbit Help Pages below regarding how sleep is calculated, based on inactivity. It seems your inactivity caused the incorrect sleep reading. The answer is simple — move to reach for snacks more frequently 😉 or turn on the Reminders to Move feature. This way, if you have not taken at least 250 steps in an hour, it will remind you to get up and walk. Or here is a compromise - Move the snacks to a table that forces you to walk to if you want more snacks?
HOW DOES MY FITBIT DEVICE AUTOMATICALLY DETECT SLEEP?
All of our wrist-based devices automatically detect your sleep, meaning you just need to wear your tracker or watch to bed. For Fitbit Flex 2, do not wear the pendant accessory while sleeping; classic accessory bands are the recommended accessory for sleep tracking.
Autodetection is based on your movement. When you haven’t moved for about an hour, your device assumes that you’re asleep. Additional data—such as the length of time your movements are indicative of sleep behavior (such as rolling over)—help confirm that you’re asleep. Morning movement tells your tracker that you’re awake. If you’re not moving but not asleep for long periods of time it’s possible for your device to falsely record sleep, in which case you can delete the sleep log from your history.
If you wear a Fitbit device with heart-rate tracking (except Charge HR and Surge) to sleep, Fitbit uses a combination of your movement and heart-rate patterns to estimate your sleep stages. For more information, see What should I know about sleep stages?
