About 5 years ago I wrote about the possibility that some insomnia sufferers may be getting more sleep than they think they are.
A new study appears to back this up - at least in older adults.
Researchers in the United States found discrepancies when comparing self-reported insomnia symptoms and data gathered from a sleep monitoring device in those aged 62-91.
Previous studies have suggested as many as half (or more) of older adults report at least one insomnia symptom - but it now appears these claims may not be entirely accurate.
In the latest study, over 700 older individuals were asked to record their opinions about their sleep. Their sleep was also measured objectively using a wrist sensor.
The data collected by the wrist sensor found that most of the participants were getting sufficient amounts of sleep (an average of 7.25 hours) and that those who reported waking the most frequently during the night were actually getting the most sleep.
This research confirms just how easy (and common) it is for us to have incorrect assumptions about our own sleep habits. That's why it's important to rely on more objective measures (such as sleep tracking devices).
Recording a sleep diary for 1 or 2 weeks can also give you a far more accurate picture of your sleep health.
