Over the years there have been varying opinions on how much sleep the average person needs. There have been many studies done on the subject of how much sleep is required to promote good health. Now there is data that suggest You might not need as much sleep as you think, but you might need better sleep.
Now with the help of wearable devices sleep data has been gathered. Using that data, Fitbit researchers compared them to users’ scores on Think Fast, an app Fitbit offers on its smartwatches. It was found that people who slept an average of 5 hours and 50 minutes to 6 hours and 30 minutes per night performed better on tests than people who slept more, or less.
These findings are in direct contrast to what doctors typically advise. Public health officials and physicians have long recommended adults sleep for at least seven hours, if not more, each night. The Fitbit researchers do admit that these guidelines are based on how much time people spend in bed as opposed to how much time people actually sleep and the numbers can vary per person, especially based on factors like age and gender.
Researchers also remind that the amount of sleep you’re getting is significantly lower than the time you spend in bed and that the optimal time is probably largely lower than what people may think. Researchers also determined that what the individuals optimum sleep is also based not only on quantity but the quality of sleep. This is especially important for older individuals.
As to what the data collected will be used for? The company plans to use the findings to send users personalized insights, so they can improve their sleep. This may include sending users notifications saying they didn’t sleep well last night along with suggestions like removing their phone from their bedroom.
