Improving sleep quality can boost cognitive performance, promote sharper thinking, and may reduce the likelihood of age-related cognitive decline.
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.
“Sleep is absolutely instrumental in cognitive function, mental acuity and the ability to concentrate and learn new things,” said Marie-Pierre St-Onge, an associate professor at Columbia University in New York City. During sleep, your brain deals with information received during the day.
"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..."
Intelligence is also strongly influenced by the environment. During a child's development, factors that contribute to intelligence include their home environment and parenting, education and availability of learning resources, and healthcare and nutrition.
FAQs (Frequently Asked Questions) When did Elon Musk take an IQ test? The Tesla CEO is estimated to have an IQ score of around 155.
Albert Einstein
Einstein's sleep habits were said to include 10 hour nightly sleeps, significantly above the average duration for most people, along with daytime naps. All of which effectively means that the world's favourite genius was also a genius sleeper!
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.
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."
Most Geniuses Perfected the Power Nap
Hence, they'd reduce the time they rest at night in order to have more functional, waking hours. Instead, they'd take advantage of the so-called “power nap”. Both Nicola Tesla and Thomas Edison were famous advocates of this principle.
Scores of studies conclude that students really do better when they sleep. Sleeping poorly (or not at all) leads to worse test results and poorer ability to learn new things. In fact, an all nighter hurts your ability to think, reason, and understand to the same degree as if you were taking your test drunk.
For most of us, five hours of sleep is not OK. Most adults need about eight hours of sleep. And while some people need five hours, it's extremely rare. For most of us, five hours of sleep can lead to sleep deprivation, low energy, poor focus, and long-term health issues.
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.
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.
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%).
There is an impressive, staircase-like correlation between IQ score and risk of death. The people with higher IQ scores were less likely to be dead at the follow-up. One million people of the same gender and the same age, and an almost perfect correlation between IQ and risk of death.
Albert Einstein, a household name that has inspired many a crazy hair day and who is most famous for his theory of General Relativity, was a huge fan of catching some Z's. He would sleep an average of 10 hours a night as well as taking daytime naps.
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.
Signs of a Genius Brain
Highly gifted or genius individuals typically have more active white matter in their brains. White matter is responsible for the communication between different parts of your brain. Genius brains seem to have a better network of these connections. It results in very quick and complex thinking.
Productivity begins even before the start of the workday. High achievers don't sleep in. Nearly 50 percent of the self-made millionaires begin their days at least 3 hours before the start of their workday.
