The new research suggests that one of the hallmarks of a sleeping disorder is that it can cause a person’s sleep history to deteriorate, increasing susceptibility to disease and death.
In addition, the researchers observed that patients who began experiencing REM sleep as late as the first month of their lives had shorter lives.
A person who is experiencing short-nightmares or sleep loss, with their early sleep, has a shorter live length, as a consequence, their life span tends to shorten.
Research that has explored the health effects of late sleep.
“People with early REM sleep have less overall sleep, so there’s less sleep to recover from later sleep,” Johnson said. “It’s quite a change of pace.”
The other researchers surveyed participants from 12 different countries with the aim of developing biomarkers to measure their sleep habits. They were asked whether or not they slept less often during the past 24 hours and then measured by using an accelerometer at bedtime. If the question was “No Sleep,” participants that also started sleeping at midnight were asked: If they had slept less than one hour earlier, and were staying awake at night, how often time spent outside was increased. If both questions were not answered, subjects who started sleeping at midnight were more likely to report a rise in “no sleep,” even if they reported no changes at all.
In the second, another set of questions asked each participant if they had seen any other health problems during the past 24 hours. Both sets of questions were based on standard sleep measurements, taking into account the fact that people will change as they’re sleeping.
“We hope that this new study shows that it’s not just a simple measurement of early and sleep-related problems,” Johnson said. “It shows that as well that it can be quantified and monitored as a biomarker.”
