The Guardian: Are sleep trackers cultivating anxiety and feeding into insomnia?
Associate Prof Darren Mansfield, a sleep disorders and respiratory physician who is also deputy chair of the Sleep Health Foundation, thinks some balance is needed.
“These devices in general can be a good thing,” he says. “They’re not as accurate as a laboratory-based sleep study, but they are progressing in that direction, and technology enables the person to be engaged in their health. Where it can become problematic is people can become a bit enslaved by the data, which can lead to anxiety or rumination over the results and significance. That might escalate any problems, or even start creating problems.”
As a clinician, Mansfield thinks that the most useful role of these devices is monitoring routine, not obsessing over the hours of good-quality sleep. “There will be some error margin, but nonetheless when we’re looking for diagnostic information, like timing of sleep and duration of sleep, they can capture that,” he says.
