Average heart rate:
Your average sleep heart rate is 5–10 beats slower than your average resting heart rate. Values of 50–70 bpm are considered healthy, but lower values are generally a sign of a healthier heart.
Average respiratory rate:
Your respiratory rate is the number of breaths you take in one minute. Most healthy adults take 10–15 breaths per minute. Faster respiratory rates can be a sign of illness or lower fitness level, while slower respiratory rates can be a sign of good health.
Awake time is the total time you spend awake between when you fall asleep and when you wake up. Ideally this time is zero minutes, but a few minutes here and there for each time you wake up is still considered normal. The ideal range for time spent awake is: 0–20 minutes
Light sleep, or stage 2 sleep, is categorized as all sleep that’s not deep or REM sleep. It’s generally viewed as the least important sleep stage. You should spend 40–60% of your total sleep time in light sleep.
Deep sleep includes both stage 3 and 4 sleep. It should account for 20–30% of your total sleep time, and is generally most prevalent in the first few hours of sleep. During deep sleep, your body repairs tissue, bone, and muscle, so it’s very important for recovery.
Rapid Eye Movement, or REM sleep, is the stage of sleep where your body is paralyzed, but your mind is very active. It’s when you dream and memory consolidation occurs. About 20–30% of your sleep time should come from REM.
Sleep time is defined as the total time you spend asleep. Awake time and time to fall asleep are not included in this value. For most individuals, 7–9 hours of sleep time is ideal, although some people may find they have lower or higher sleep needs.
Times woke up:
The times you woke up is the total number of times that your sleep was disturbed to the point of wakefulness. Ideally this number is zero, but since that isn’t always realistic, the lower it can be, the better.
Time to fall asleep:
Generally it takes most adults about 15 minutes to fall asleep. If you’re falling asleep significantly faster, it’s likely a sign of sleep deprivation. If you’re taking more than 20 minutes to fall asleep, it could be a sign of a sleeping disorder or stress.
Exits out of bed:
This is the total number of times you left your bed. If you find yourself waking up often to use the restroom, try limiting fluids two hours before bedtime. Ideally there should be zero exits from bed.
Your sleep efficiency is the ratio between your time in bed and your sleep time. The more time you can spend in actual sleep, the better. Most individuals are around 80–95% efficiency, but anything close to 95% is ideal.
Time in bed:
Your time in bed is the total of sleep time, awake time, and time to fall asleep. Ideally you want this value to be within 30 minutes of your total sleep time.
