New research indicates that inadequate sleep may significantly impact life expectancy, surpassing the effects of diet and exercise, according to a study from Oregon Health & Science University.
Inadequate sleep could be shortening lives more than previously understood. New research from Oregon Health & Science University (OHSU), published in the journal Sleep Advances, reveals that poor sleep may reduce life expectancy more than other lifestyle factors such as diet, exercise, and even loneliness.
The study analyzed nationwide survey data from the Centers for Disease Control and Prevention (CDC), identifying trends associated with average life expectancy by county. The findings indicate that insufficient sleep correlates with a higher risk of mortality across all U.S. states, ranking as the leading behavioral factor influencing life expectancy, second only to smoking.
Dr. Andrew McHill, the senior author of the study and an associate professor at OHSU, expressed surprise at the strength of the correlation between sleep and life expectancy. “We’ve always thought sleep is important, but this research really drives that point home,” he stated. “People really should strive to get seven to nine hours of sleep, if at all possible.”
Dr. McHill emphasized the need to prioritize sleep as much as diet and exercise. “This research shows that we need to prioritize sleep at least as much as we do what we eat or how we exercise,” he added.
In a previous interview with Fox News Digital, psychiatrist Dr. Daniel Amen, who operates Amen Clinics in California, highlighted the critical role sleep plays in brain function and overall longevity. “Sleep is so important,” he remarked. “When you sleep, your brain cleans and washes itself. If you don’t sleep seven to nine hours at night, your brain looks older than you are — there’s less blood flow, and it increases inflammation in the brain.”
Dr. Amen pointed out that insufficient sleep prevents the brain from effectively eliminating toxins that accumulate throughout the day. He warned that a lack of adequate sleep can lead to poor decision-making and create toxic cycles. “If your brain has less activity in the front part, not only are you tired, but you’re also hungrier, and you’re more likely to not make the best decisions,” he explained. “Which, of course, will stress you out, and then you won’t sleep well the next night.”
To promote longevity and enhance brain health, Dr. Amen suggested making small adjustments to sleep habits, such as going to bed 15 minutes earlier. “Really be purposeful about not being distracted by Netflix or your phone,” he advised. “And when you get up in the morning, say to yourself, ‘Today is going to be a great day.’ The more positive you are, the better your brain.”
This research underscores the importance of sleep in maintaining not just physical health but also cognitive function and emotional well-being. As the evidence mounts, prioritizing sleep may be one of the most effective strategies for enhancing longevity and quality of life.
According to Fox News, the implications of this research are significant, urging individuals to reassess their sleep habits in light of these findings.
