Psychologist Satoshi Kanazawa and Study Magazine pinpointed further by saying that individuals in their 20s with a normal IQ tended to go to sleep at around 12:10 a.m., while those with a lower IQ went to bed at 11:41 p.m. Those labeled “very bright” hit the sack at 12:29 a.m.
Studies show that night owls and those who wake up later actually are smarter and more creative than their early rising counterparts. They also have higher IQs according to The Independent. Unfortunately, night owls have slightly lower academic scores than early risers (by about 8%).
Those with an IQ of over 125 tended to go to bed around 12:30 a.m. and wake up around 8:00 a.m. on weekdays, and go to bed around 1:45 a.m. and wake up around 11:00 a.m. on weekends. Those of normal intelligence tended to sleep from 12:00 a.m. to 7:30 a.m. on weekdays and from 1:15 a.m. to 10:15 a.m. on weekends.
Did you know that insomnia is more common for those who have a high IQ. Intelligent people have a harder time switching off their brain. So, maybe you are just too clever to snooze! Don't panic, high IQ or not, cognitive behavioural therapy for insomnia can help you.
Overall, our analysis of an adult sample suggests that highly intelligent individuals do not have a biological preference for a later chronotype: while they do go to bed, sleep, and wake up later on work days, this effect is fully mediated by later working times and not present on free days or in the corrected ...
But the majority manage to get at least 6 hours, as you can see in the list below detailing the sleep habits of 10 highly successful people: Elon Musk, CEO of Tesla and SpaceX: 6 hours (1am — 7am) Tim Cook, CEO of Apple: 7 hours (9:30pm — 4:30am) Bill Gates, Co-Founder of Microsoft: 7 hours (12am — 7am)
Scientists have long known that our ability to think quickly and recall information, also known as fluid intelligence, peaks around age 20 and then begins a slow decline.
Most Geniuses Perfected the Power Nap
That's pretty much true. Since a lot of them tend to believe that it is absolutely imperative to stay ahead, they seem to think that sleeping deprives them of this opportunity. Hence, they'd reduce the time they rest at night in order to have more functional, waking hours.
Power naps are short periods of sleep taken in order to restore mental alertness and ward off sleepiness. Another genius who utilized napping during the day was Leonardo Da Vinci. Da Vinci created what is called the polyphasic sleep process, or, the Da Vinci Sleep Schedule.
Many people with high level of intelligence lean towards over-thinking and keep analyzing everything that occurs in their life, their surroundings and beyond. Too much thinking can be exhausting at times, especially when your thoughts lead you to conclusions which vex and frustrate you.
Albert Einstein is said to have slept 10 hours per night, plus regular daytime naps. Other great achievers, inventors, and thinkers – such as Nikola Tesla, Thomas Jefferson, Thomas Edison, Winston Churchill, Leonardo da Vinci, and Sir Isaac Newton – are said to have slept between two and four hours per day.
10 HOURS OF SLEEP AND ONE-SECOND NAPS
It's common knowledge that sleep is good for your brain – and Einstein took this advice more seriously than most. He reportedly slept for at least 10 hours per day – nearly one and a half times as much as the average American today (6.8 hours).
Some studies show that speaking more rapidly makes you seem more intelligent, possibly because speed implies certainty. So what should you do? There's a better approach than simply speaking quickly or slowly, because how quickly you should speak can depend on the situation you're in.
Intelligent People are more Likely to Sleep Late
In a study of over 20,000 adolescents over a 5 year period, Psychologist Satoshi Kanazawa found that “intelligent individuals are more likely to be night owls.” This stayed true across a wide swath of variables, including ethnicity, education, and religion.
Busy Brains
Gifted kids seem to be able to function quite well with less sleep than their age mates, but they can sometimes have a difficult time getting to sleep. Many kids describe it as being unable to shut off their brains. They simply can't stop thinking.
Interestingly, only a bit more than one-third (37 percent) of people in the study actually identified as early birds or night owls (13 percent and 24 percent respectively), although it's worth noting that evening types on 24 percent were the most common chronotype.
Elon Musk says he's upped his sleep to 6 hours per night—and that his old routine hurt his brain.
Inventor Nikola Tesla never slept for more than two hours a day. Tesla got more out of the day with his limited sleep schedule. He claimed to never sleep for more than two hours a day and reportedly once worked for 84 hours in a lab without sleep.
Replying to a post on Threads, his new social media app, asking how much sleep people get at night, the Meta CEO Mark Zuckerberg casually admitted to getting between seven and eight hours' slumber daily — but it comes at a cost.
How much sleep did Beethoven get? Between 1822 and 1827, Beethoven had a pretty balanced schedule. He got 8 hours of sleep, from 10 p.m. to 6 a.m. After a light breakfast (coffee), he'd start a nice 8-hour workday of composing from 6:30 a.m. to 2:30 p.m.
Successful people often sleep less because they are highly motivated and driven to achieve their goals, which can lead to working long hours. Additionally, some people may have a genetic predisposition towards being able to function well on less sleep.
What age is your mind the sharpest? The human brain attains peak processing power and memory around age 18. After studying how intelligence changes over time, scientists found that participants in their late teens had the highest performance.
Elon's IQ is estimated to be around 155, while Albert Einstein's is 160. With such a slight margin, Musk is undoubtedly an incredibly smart person. Who is the smartest person on earth in 2022? Born in 1975 in Adelaide, Australia is a mathematician, Terence Tao with an IQ score of 230.
Children's intelligence fluctuates as they develop. It used to be held that IQ stabilises by around the age of 10. This was the rationale for introducing tests at 11-12 years of age in those education systems where ability is used to select which secondary school children attend.
They also wake up very early. In my work with famous entrepreneurs, Fortune 500 CEOs and billionaires, I have seen that getting up early has so many benefits that it is no wonder that most of the world's most successful business leaders get up much earlier than the rest of the world.
