Millions of people approach sleep the same way every night without questioning whether their habits actually align with what their body needs. A physician recently offered five facts that may prompt a serious reassessment — beginning with the finding that women need more sleep than men, a difference rooted in how the brain uses and recovers from daily activity.
The physician explains that women may require around 20 more minutes of sleep per night than men. This difference is linked to the multitasking demands many women experience throughout the day. Constant task-switching and the management of multiple responsibilities at once taxes the brain in ways that require extended overnight recovery. Sleep is when the brain processes and files away the day’s experiences — and heavier mental workloads demand more filing time.
How long it takes to fall asleep is also a significant but often overlooked indicator of sleep health. The healthy range is between 10 and 20 minutes. Falling asleep faster than this consistently suggests accumulated sleep deprivation, while regularly taking longer may be an early sign of insomnia. Paying attention to this window can help identify sleep problems before they become chronic.
Dream recall — or rather the lack of it — is another important piece of the sleep puzzle. Approximately 95 percent of our dreams disappear from memory within minutes of waking up, simply because the brain doesn’t store dream experiences in long-term memory. If understanding your dreams matters to you, keeping a journal next to your bed and writing immediately upon waking is the single most effective habit you can adopt.
The physician’s final two insights offer important guidance for daily life. After 17 hours of continuous wakefulness, cognitive performance declines to a level equivalent to mild intoxication — making it genuinely risky to drive, make complex decisions, or engage in tasks requiring precision and focus. And when it comes to melatonin supplements, restraint is key: 0.5 mg is often far more effective than higher doses because it closely resembles what the body naturally produces.
