There’s no doubt that exercise is good for sleep – many studies have documented the benefits of exercise to improving general sleep patterns. However new advances in sleep tracking from Fitbit can now go that step further to give you personalised guidance and actionable insights to help you improve your sleep from your Fitbit data.
By tapping into your night-time heart rate and movement patterns, Fitbit devices* will now be able to estimate how much time you spend in light, deep, and rapid eye movement (REM) sleep.
By logging each of the stages of your sleep, along with the whole of your Fitbit data (everything from your diet to your exercise patterns), Fitbit can now discover trends about what may be affecting your sleep and offer you tailored guidance on how to improve it.
For example, if you use a Fitbit device that automatically tracks sleep, one insight via the Fitbit app may read: “There seems to be a strong correlation between your sleep and your runs. The last 10 weeknight logs show that you had 20 mins more restful sleep on days you ran vs. days you didn’t.”
This kind of information previously only accessible through a sleep lab can help you better understand how exercise and diet directly affects your sleep patterns. Furthermore, it will help you to make lifestyle changes that will improve the quality of your sleep overtime and, in turn your overall health – something we certainly approve of.
Each stage of sleep serves a different purpose, so understanding how much of each stage you log can help you identify and address sleep-related issues. Below is a breakdown of what you need to know about each sleep stage:
- Light Sleep (including sleep stages 1 and 2) occurs throughout the night and is important for memory, learning, and letting your body recover from the day; for most people it is 50-60 percent of your night.
- Deep Sleep (sleep stage 3) promotes a healthy immune system and muscle growth and repair; for most people it is 10-25 percent of your night (depending on age).
- Rapid Eye Movement (REM) Sleep is when most dreaming occurs and is important for mental recovery and memory formation; for most people it is 20-25 percent of your night. Most REM sleep comes at the end of the night, and is often the stage that’s cut short when your sleep duration decreases.
- Awake minutes (between 10-30 times per night) are a normal part of your sleep cycle each night, and is typically when your heart rate is more elevated during sleep.
