On Thursday, the health and fitness wearable company Fitbit has confirmed the ability of its wrist-worn trackers, which include movement and heart sensors to accurately determine the stages of sleep – light, deep and fast eye movements (REM), the company said on Thursday.
The reports claimed that recently launched devices, such as Fitbit Alta HR, Blaze and Charge 2, can be used to track sleep stages with a reasonable degree of accuracy in normal adult sleepers.
In the application, Head researcher fellow for sleep search at Fitbit said that “With the help of our sleep tracking tools, Fitbit has transformed what people can learn about their sleep habits by taking the ability to track sleep stages from the lab and put it on the wrist.”
For the study, the researchers have tracked more than four billion nights of sleep from 2010, regardless of polysomnography techniques.
They found that if you sleep longer, it will lead to a deeper and more rapid sleep, sleep for seven to eight hours gives you the greatest combined percentage of time in the total sleep cycle.
In addition, the generation Z (13-22 years old) found the most sleep, sleeping 6 hours 57 minutes a night while in an average of 17 hours of deep sleep; Baby boomers (52-71 years) sleeping at least 33 hours at night, with 13% of deep sleep time.
People get less sleep as they get older, from an average of 17% in their 20’s to 12% in their 70’s.
The researchers found that women had a higher percentage of REM sleep when they slept for about 25 minutes than men, and that this difference was even greater at around 50 years.
The findings will be presented at SLEEP 2017 jointly organized by the American Academy of Sleep Medicine and the Sleep Research Society in Boston.
