Yes, sleeping at 10 pm is generally considered excellent for health, aligning well with your body's internal clock (circadian rhythm) and potentially lowering risks for heart disease, especially if it allows for 7+ hours of sleep before a typical morning wake-up, though consistency is key, and individual needs vary.
The BHF verdict. Regina Giblin, Senior Cardiac Nurse at the British Heart Foundation, said: “This large study suggests that going to sleep between 10 and 11pm could be the sweet spot for most people to keep their heart healthy long-term.
At around 10pm, our bodies go through a transformational phase following the rise in melatonin secretion. Melatonin continues to rise and it is in this early phase of sleep where our body undergoes repair and restoration until it reaches a peak between 2am and 4am.
“Getting to bed around 9.30-10pm is optimal and it is one of the non-negotiables in my sleep protocol,” says sleep expert Dr Nerina Ramlakhan. When we are well rested, our anxiety reduces, mental focus improves, and exercise feels easier. There are long-term benefits to early nights, too.
An adult should sleep 7 to 8 hours. If you are physically fit then you can sleep at 5 and wake up at midnight. As long as you feel good and you have a rich day, then there is nothing wrong with waking up in midnight. Usually people sleep at 10 pm and waking up at 6 am. If you have shift work or anything you may do.
Gen Z's lifestyle has dramatically shifted bedtime patterns compared to previous generations. Many young people go to bed extremely late, often past midnight, which creates a misalignment between their biological clock and societal expectations.
The koala is famous for sleeping around 20-22 hours a day, which is about 90% of the day, due to their low-energy diet of eucalyptus leaves that requires extensive digestion. Other extremely sleepy animals include the sloth (up to 20 hours) and the brown bat (around 20 hours), with some snakes like the ball python also sleeping up to 23 hours daily.
A “danger nap” refers to a late-afternoon nap that potentially disrupts a child's regular bedtime, leading to a later sleep onset. Traditionally, parents have been advised to prevent these naps to maintain consistent (earlier) bedtime routines. However, this perspective may not be universally applicable.
Gen Z stays up late due to a combination of technology (blue light, endless content), significant stress and anxiety (FOMO, financial/global worries), biological shifts (natural teenage circadian rhythm), and "revenge bedtime procrastination," where they sacrifice sleep for personal time, often in bed, scrolling social media. This digital-heavy, high-stress lifestyle creates overstimulation and a misalignment with natural sleep patterns, leading to chronic sleep deprivation, notes the American Academy of Sleep Medicine and the Sleep Health Foundation.
The 10-3-2-1-0 rule is a popular sleep hygiene guideline that creates a countdown for winding down before bed, advising: 10 hours without caffeine, 3 hours without big meals or alcohol, 2 hours without work or stressful activities, 1 hour without screens (phones, TV, computers), and aiming for 0 snoozes in the morning, promoting better sleep quality by reducing stimulants and preparing the body and mind for rest.
For most healthy adults, guidelines suggest at least seven hours of slumber. But these are general recommendations and not strict rules. "Some people need less than seven hours, while others might need more," says Eric Zhou with the Division of Sleep Medicine at Harvard Medical School.
And How to Stay Energized
In part, it is physiological: Our normal circadian cycle dictates a period of sleepiness or decreased alertness in the afternoon. However, sleep disorders, medical disorders, stress, insufficient sleep or poor eating habits can also cause excessive sleepiness at this time.
Sleeping between 10–11 pm is associated with a decreased risk of developing cardiovascular disease (CVD) compared with earlier or later bedtimes, according to a study — suggesting that this timing represents the optimal sleeping time for better heart health.
The 10-3-2-1 sleep method (often 10-3-2-1-0) is a simple pre-sleep routine guiding you to stop certain activities at specific times before bed for better rest: 10 hours without caffeine, 3 hours without food or alcohol, 2 hours without work, and 1 hour without screens (phones/TVs), with 0 snoozes in the morning, helping to naturally wind down for sleep.
Try to get 7-8 hours of sleep each night, sleeping as much as possible before midnight. Your body repairs itself best between 10 p.m. and 2 a.m. If you have trouble relaxing or falling asleep: Go to bed only when you feel sleepy. Lay in bed only for sleep, not for work or watching TV.
Whilst boomers and millennials may use the 😂 emoji, this has long since been deemed 'uncool' (or 'cheugy') by Gen Z. Instead, this has been replaced by the skull (💀) or the crying emoji (😭), dramatising the idea of 'dying with laughter'.
Some evidence suggests that high IQ is associated with later sleep patterns. However, it is unclear whether the relationship between IQ and later sleep is due to biological or social effects, such as the timing of working hours.
Across much of the world, it is no longer middle-aged adults who are the most miserable. Instead, young people, especially Gen Z, are reporting the highest levels of unhappiness of any age group.
The 5-3-3 rule is a baby sleep training method for night weaning and fostering independent sleep, involving a baby sleeping 5 hours, staying awake for 3 (for a feed if needed), then sleeping another 3 hours, and continuing in 3-hour increments, teaching them to self-soothe after the initial long stretch, though it's a flexible guideline, not strict; it aims to create longer stretches for parents while meeting the baby's needs, often used around 4-6 months.
The 2-3-4 nap rule is a popular baby sleep guideline for babies around 6 months and older, suggesting wake windows: 2 hours from waking until Nap 1, 3 hours from Nap 1's end to Nap 2, and 4 hours from Nap 2's end to bedtime, creating a balanced 2-nap-a-day schedule with about 3 hours of total nap time. It helps structure days and build sleep pressure but isn't for every baby, as individual needs vary.
“It's best to nap earlier in the afternoon, like before 2 p.m. or 3 p.m.,” Dr. Foldvary-Schaefer shares. Any later in the day may make it harder for you to fall asleep at night.
Among the most rested countries surveyed by Sleep Cycle, an app that tracks how much shuteye people are getting, New Zealand comes top with the average Kiwi clocking up in excess of 7.5 hours per night. Finland, the Netherlands, Australia, the UK and Belgium all rank highly for sleep, too, with Ireland close behind.
The answer is “probably.” Research has shown that many animals experience a sleep phase similar to humans known as REM (Rapid Eye Movement) sleep, which is closely associated with dreaming. This phase is characterized by increased brain activity and is when most vivid dreams occur.
