Sleeping less than five hours associated with higher risk of dozens of diseases in large study tracking nearly 100000 adults extensively and consistently. Researchers discovered encouraging evidence that six to eight hours nightly sleep supports lower risks across many major health conditions positively and significantly.
Furthermore, comprehensive analysis found people spending more time in REM and deep sleep tended toward lower risks of several major conditions consistently and hopefully.
How Researchers Tracked Sleep Objectively
Specifically, researchers analyzed 95559 UK Biobank participants who wore wrist accelerometers continuously for seven days and nights consistently and accurately and objectively. Meanwhile, advanced deep learning algorithm estimated total sleep time, REM sleep, deep sleep, light sleep, wakefulness, and nightly variability comprehensively and objectively and reliably.
Importantly, greater REM sleep duration associated with lower rates of 83 distinct diseases, including heart failure, dementia, and Parkinson’s disease remarkably and encouragingly positively.
Remarkable Links Between REM Sleep And Disease Protection
Additionally, each additional 47.6 minutes REM sleep linked to 26 percent lower heart failure rate during median 8.9 years follow-up period encouragingly. Moreover, same REM increase associated with 46 percent lower dementia rate and 80 percent lower Parkinson’s disease rate encouragingly and significantly overall positively.
Furthermore, more deep sleep duration associated with reduced risk of seven important conditions, including type 2 diabetes and major depressive disorder significantly and hopefully.
Why Irregular Sleep Raises Risk
Conversely, greater night-to-night sleep irregularity and more wakefulness after falling asleep associated with higher risks of anxiety and substance use disorders notably and consistently. Nevertheless, researchers emphasize observational study did not prove causation, as other health, behavioral, biological factors could contribute to associations observed potentially and indirectly.
Ultimately, six to eight hour sleep window stood out clearly, with lowest risk concentrated within that range for 69 of 86 conditions positively and consistently.
The Power Of Objective Tracking
Additionally, people sleeping less than five hours nightly showed greatest overall vulnerability, with higher risks of 37 different conditions across full analysis significantly.
Furthermore, researchers identified 156 statistically significant associations between diverse sleep patterns and newly diagnosed diseases after rigorous Bonferroni correction method applied carefully.
Moreover, objective wearable tracking adds valuable precise detail beyond self-reports, examining several sleep dimensions simultaneously for nearly nine years median follow-up accurately.
Good News For Prevention
Consequently, authors concluded maintaining six to eight hours nightly sleep can effectively reduce multiple disease risks, supporting health promotion and preventive practice strongly and positively. Therefore, findings provide additional compelling evidence supporting six to eight hours sleep as important health safeguard for middle-aged and older adults generally and hopefully.
Ultimately, this research highlights hopeful positive message that improving sleep duration and quality may support long-term wellness and disease prevention strategies effectively and encouragingly.
Q&A
Q: How much sleep was linked to lowest disease risk in this large UK Biobank study of 95559 adults?
A: Researchers found six to eight hours nightly sleep associated with lowest risk for majority of conditions, specifically 69 of 86 disease phenotypes analyzed.
Q: How much does extra REM sleep lower risk of heart failure, dementia, and Parkinson’s according to findings?
A: Each additional 47.6 minutes REM sleep linked to 26 percent lower heart failure, 46 percent lower dementia, and 80 percent lower Parkinson’s risk.
Q: Did researchers prove that improving REM and deep sleep directly prevents diseases like dementia and diabetes?
A: No, researchers emphasized observational associations only, noting other health, behavioral, biological factors could contribute, requiring further interventional research for causation confirmation.
FAQ
Q: What did the UK Biobank wearable study find about sleeping less than five hours nightly?
A: People sleeping less than five hours nightly showed greatest overall vulnerability, with higher risks of 37 different conditions across full analysis significantly.
Q: How does deep sleep benefit health according to this new 8.9-year follow-up study?
A: More deep sleep associated with reduced risk of seven conditions, including type 2 diabetes and major depressive disorder, supporting metabolic and mental wellness.
Q: Why is objective accelerometer tracking better than self-reported sleep estimates for health research?
A: Self-reports often differ from objective measurements, while wearables accurately estimate REM, deep, light sleep, wakefulness, and irregularity simultaneously and reliably.
Q: Does irregular sleep timing increase health risks even if total duration seems adequate?
A: Yes, greater night-to-night irregularity and more wakefulness after sleep onset associated with higher anxiety and substance use disorders risks notably.
Q: Can improving sleep duration to 6-8 hours really help prevent multiple diseases long-term?
A: Authors concluded maintaining six to eight hours nightly sleep can effectively reduce multiple disease risks, providing new insights for preventive health promotion.
