Psychology Today reported that intelligent people are likely to be nocturnal beings, with those with a higher IQ going bed later on both weeknights and 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.
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.
The macrostructure of sleep has a small but consistent correlation with intelligence, with possible nonlinear effects. Biological and social factors contribute to the relationship between sleep macrostructure and intelligence.
Studies have shown that people with higher IQs are likely to deviate from familiar evolutionary traits, such as circadian rhythms. Night owls who opt to wake up in the later hours of the day and stay awake until the wee small hours of the morning may be exhibiting a form of evolution.
To Conclude. Now, it's evident that not all geniuses have different sleeping patterns and it's also quite evident that some of them do. Ultimately, however, there is no clear link between the time you spend sleeping and your levels of intellect.
Less sleep lowers IQ scores and grades
According to Coren, scores on intelligence tests decline cumulatively on each successive day that you sleep less than you normally sleep. The daily decline is approximately one IQ point for the first hour of sleep loss, two for the next, and four for the next.
"An hour of sleep less per night causes only a 1 or 2 point reduction in IQ, but cumulative sleep deprivation can effect an IQ reduction of as much as 15 points..."
Sleep problems may, in turn, contribute to psychological problems. For example, chronic insomnia may increase an individual's risk of developing a mood disorder, such as depression or anxiety. In one major study of 10,000 adults, people with insomnia were five times more likely to develop depression.
A study published in the journal Sleep found that sleep is important for cognitive performance and that individuals who have better sleep quality tend to have higher intelligence scores.
Elon Musk says he's upped his sleep to 6 hours per night—and that his old routine hurt his brain. Elon Musk, CEO of Tesla, speaks with CNBC on May 16th, 2023. Elon Musk says his days of trying to sleep less and work more are over — at least, relatively speaking.
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. This process entails 20-minute power naps throughout an entire 24-hour period. This results in about 5 hours of sleep every 24 hours.
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.
Staying Up Late
Intelligent people are more likely to have different sleep cycles (or circadian rhythms) than people with a lower IQ. In fact, research indicates that there's a strong correlation between intelligence and bedtime. That is the higher your IQ, the later you'll stay up.
In his blog "A Geek With A Hat," Swizec Teller — a programmer — explains why you can actually concentrate better when your brain is exhausted. He says it's because your brain is so tired, it has to focus. In other words, "there isn't enough left-over brainpower to afford losing concentration."
Short-term cannabis use appears to increase the time you spend in deep sleep, the stage that helps you wake up feeling refreshed. However, THC decreases the amount of time you spend in rapid eye movement (REM) sleep, when you spend more time dreaming, processing emotions, and cementing new memories.
Lower than average scores on IQ tests. Difficulties talking or talking late. Having problems remembering things. Inability to connect actions with consequences.
The largest sleep study ever concludes that sleeping too little or too much has a negative impact on our cognitive ability, but not on our short-term memory.
You're stressed out.
"High stress levels are not only associated with poorer brain functioning but may even link to an increased risk of Alzheimer's disease," says Brendan Kelley, MD, neurologist at The Ohio State University Wexner Medical Center in Columbus, Ohio.
Talking to yourself, it turns out, is a sign of genius. The smartest people on earth talk to themselves. Look at the inner monologues of the greatest thinkers.
Geniuses think productively, not reproductively
They tend to come up with many different responses, some of which are unconventional and possibly unique. Leonardo da Vinci believed that to gain deep knowledge about a problem, you have to learn how to restructure it in many different ways.
Those who have a higher IQ and tend to process more information than others tend to dream more often because there are more thoughts going through the mind. Most people dream every occasionally. If you dream several times during the week, it might be because you have a higher IQ than others.
