Bill Gates prioritizes getting 7 to 8 hours of sleep per night, a significant shift from his earlier days at Microsoft when he'd pull all-nighters, recognizing sleep's crucial role in creativity, decision-making, and overall brain health, even tracking his "sleep scores" to ensure quality rest.

Einstein slept nearly 10 hours a day. He valued the significance of quality sleep for maintaining his well-being. His sleep routine, though, was out of the ordinary. He regularly indulged in brief daytime naps, occasionally more than once a day.
Musk goes to bed around 3 a.m. and gets about 6 hours of sleep every night. Although he's not getting eight hours a night, Musk has upped his sleeping schedule from being nearly nonexistent in the past. In May 2023, Musk told CNBC that he's no longer pulling all-nighters.
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.
Jeff Bezos on sleep: "I get 8 hours of sleep, I prioritize it - I think better, I have better energy. You get paid to make a small number of high quality decisions." Staying up all night working is not a badge of honor. You're never going to survive long term that way.
Idiopathic Hypersomnia
With this disorder, you may sleep as much as 14 to 18 hours a day. For treatment, doctors often prescribe medications similar to what is prescribed for narcolepsy. These medications may not treat idiopathic hypersomnia as effectively as they treat narcolepsy, however.
The longest time a human being has gone without sleep is 11 days and 25 minutes. The world record was set by American 17-year-old Randy Gardner in 1963. When the experiment ended, Gardner had been awake for 264 hours and 25 minutes.

The Impact of Getting Only 6 Hours of Sleep. Although many people believe they can learn to live on fewer hours of sleep, research does not support this idea. Experts agree that sleeping less than the recommended amount can have consequences for a person's health and well-being.
Jeff Bezos's "1-Hour Rule" is a morning routine emphasizing a slow, screen-free start to the day, allowing for "puttering" (reading, coffee, family time) to improve focus and decision-making by avoiding immediate digital distractions, which aligns with neuroscience findings on brain health and stress reduction. Instead of emails, the first hour is for intentional, calm activities to prepare the mind for high-IQ work later in the day, setting a tone for better energy and clearer thinking.
A 72 IQ is considered Borderline Intellectual Functioning (BIF), falling just above the threshold for intellectual disability (usually around 70), placing it in the lower end of the spectrum (70-79) and indicating slower learning and potential needs for support in daily living, though it's not low enough for an official intellectual disability diagnosis by itself, notes Quora user. It's in the bottom few percentiles of the population, requiring more time to grasp complex concepts but not necessarily severe impairment.
The 3-2-1 sleep rule is a simple wind-down routine: stop eating and drinking alcohol 3 hours before bed, stop working/mentally stimulating activities 2 hours before, and turn off screens (phones, TVs) 1 hour before sleep, helping you transition to rest by reducing stimulants and preparing your mind and body. It's often part of a larger 10-3-2-1-0 rule, which also adds no caffeine 10 hours prior and no hitting snooze (0) in the morning.

Thomas Edison, inventor and father of the light bulb is said to have slept as little as four hours a night, compensating with frequent catnaps throughout the day.
Some people prefer nine hours of sleep. Albert Einstein is said to have slept 10 hours per night, plus regular daytime naps.
Elon Musk's "1-Hour Rule" (often called the 5-Hour Rule) is about dedicating at least one focused hour each weekday (five hours a week) to deliberate learning, reading, or deep thinking, without distractions, to foster continuous growth and problem-solving, a practice also attributed to leaders like Bill Gates. This isn't about working harder but thinking deeper, allowing for crucial reflection amidst constant output, with Musk's own experience highlighting how focused, distraction-free time yields better results than hours of unfocused work.
