I wrote just three days ago in my post on sleep mistakes, “Sleep is one of the truly under-appreciated aspects of living a long and healthy life….” So, I sympathize with anyone taking steps to improve their sleep. It turns out, however, that using some of the new devices can have a negative impact on your overnight rest. The following is from the Rush University Medical Center.
A 39-year-old man whom we’ll call Mr. R received a sleep-tracking device from his girlfriend. Since starting a new job several years earlier, he sometimes had trouble getting a good night’s sleep. Not surprisingly, the next day he’d feel tired, irritable and absentminded.
Based on data generated by his girlfriend’s gift, Mr. R concluded those symptoms occurred only after he failed to get eight hours of sleep the night before. He set himself an ambitious goal: “to achieve,” as he later told a therapist, “at least eight hours of sleep every night.”
His gauge for deciding whether he had succeeded: his new sleep tracker. And so each night, Mr. R went to bed feeling the pressure of ensuring that the next morning the tracker would display the desired eight hours — a self-induced level of increasing anxiety that’s hardly the ideal recipe for achieving a sound night’s sleep.
