It's now confirmed: nearly one-third of adults struggle to obtain the ideal 7-9 hours of sleep each night, according to specialists at Flinders University, who determined that 31% of individuals experience average sleep lengths falling outside this recommended guideline.

This comprehensive international investigation, involving thousands of participants and featured in Sleep Health, revealed that just 15% of respondents managed the optimal 7-9 hours on five or more evenings weekly. Furthermore, even among those averaging 7-9 hours nightly across a nine-month tracking phase, roughly 40% of their nights deviated from this desirable window.

"This matters immensely since habitual insufficient sleep—or potentially excessive rest—carries significant negative impacts, and we're only beginning to fully grasp the repercussions of such inconsistent patterns," explains Dr. Hannah Scott, a researcher from Flinders University.

"Evidently, consistently hitting the advised sleep duration proves difficult for numerous individuals, particularly amid the demands of the workweek."

The team from Flinders analyzed sleep tracker information gathered via an under-mattress device, scrutinizing sleep lengths over nine months for nearly 68,000 adults globally. The dataset included 67,254 participants (52,523 men and 14,731 women), predominantly from Europe and North America, with their sleep data captured by the Withings under-mattress Sleep Analyzer.

Averaging under six hours of sleep nightly correlates with heightened mortality risks alongside various health issues like hypertension, obesity, and cardiovascular disease. Similarly, routinely getting fewer than seven hours or more than nine hours daily connects to detrimental effects on health and overall well-being, encompassing problems with digestion and neuro-behavioral functions.

Women in the study typically enjoyed longer sleep periods compared to men, while middle-aged individuals logged shorter durations than both younger and older groups.

"Drawing from these results, initiatives in public health and advocacy must empower communities and individuals alike to secure more consistent sleep aligned with age-appropriate recommendations," states co-author Professor Danny Eckert, an Australian National Health and Medical Research Council leadership fellow and head of Sleep Health research at Flinders University.

"Considering the vital role sleep plays in maintaining health, it's essential to guide people in overcoming persistent sleep challenges and to urge everyone to elevate sleep as a key priority in their lives."

habitual snoring also links to hypertension, as highlighted in a separate recent Flinders University study.

Researchers at Flinders offer the following practical strategies to foster an improved sleep routine:

• In the immediate term, individuals should aim to stick to a sleep timetable that leaves them feeling adequately refreshed, doing so as frequently as feasible. Sticking to a steady wake-up hour—even during weekends—and retiring when drowsiness sets in can promote regular acquisition of rejuvenating sleep.
• For those unable to adhere to a steady schedule owing to unavoidable obligations like shift work, incorporating compensatory rest periods is advisable.
• Be vigilant for signs of inadequate sleep, including daytime sleepiness, exhaustion, difficulty sustaining focus, weakened memory, and risks of errors such as while operating a vehicle. These could stem from insufficient quantity or suboptimal quality of sleep, as seen in conditions like obstructive sleep apnea.
• Individuals suspecting they fall short on sleep—particularly those averaging under seven hours—might experiment with extending their sleep window or adding short naps to determine if this leads to prolonged rest and greater refreshment.
• Absent any diagnosed sleep disorders, embracing solid sleep hygiene practices can prove advantageous. This involves steering clear of caffeine and alcohol later in the day, curtailing overall intake of these substances, and skipping heavy meals near bedtime, all of which may facilitate quicker sleep onset and extended duration. While not everyone benefits equally from such measures, they're straightforward to implement and could address sleep woes effectively.
• If sleep concerns persist, the initial step should be consulting a general practitioner. From there, referrals to sleep experts can unlock treatments for diverse disorders including sleep apnea and insomnia.
