Does your sleep tracker accurately provide you with all the information you need? — AFP Relaxnews
Connected devices designed to monitor – and therefore improve – one’s sleep are becoming increasingly popular around the world, but do they really bring benefits to the user? A team of American researchers has looked into the subject, revealing that trackers marketed on a large scale are far from equal in terms of efficiency.
While it's easy to know whether one has had a good night’s sleep or a night full of waking, it is more complicated to accurately evaluate the time spent sleeping, or even in the waking-up process, and even more complicated to analyse with certainty how restful this sleep has been. For a few years now, small connected personal devices have been available to carry out this task while you let yourself be lulled to dreamland. But few independent studies have so far evaluated the effectiveness of these trackers, which are more and more numerous on the market.
