It is possible to be too obsessed with sleep, reports Shape.

Some people become preoccupied with their sleep data, according to a case study published in the Journal of Clinical Sleep Medicine that looked at several patients who had sleep troubles and were using sleep trackers to collect information about their sleep. The researchers involved in the study came up with a name for the phenomenon: orthosomnia. That essentially means being overly concerned with getting “perfect” sleep. Why is that a problem? Interestingly enough, having too much stress and anxiety around sleep can actually make it harder to get the HQ shut-eye you’re after.
