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.
Neuroscience says you lose 5% of IQ points every time you don't get enough sleep. Leaders who understand how brains work can make themselves and their teams more nimble, innovative, and resilient.
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."
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.
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.
The sleep deprivation group had significantly lower subtest scores, verbal intelligence quotient (IQ) (VIQ), performance IQ (PIQ) and full scale IQ (P<0.05) and significantly lower verbal comprehension factor score and memory/attention factor score compared with the control group (P<0.05).
Elon Musk IQ is close to this starting point, with an estimated score of 155. The typical genius has an IQ of around 140.
Difficulties talking or talking late. Having problems remembering things. Inability to connect actions with consequences. Difficulty with problem-solving or logical thinking.
Researchers have previously shown that a person's IQ is highly influenced by genetic factors, and have even identified certain genes that play a role. They've also shown that performance in school has genetic factors. But it's been unclear whether the same genes that influence IQ also influence grades and test scores.
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).
He says he likes getting around six to six-and-a-half hours of sleep per night. Sleeping in is not an option for him, saying it affects his performance more than if he sleeps less. After getting up, he showers, dresses, and enjoys a morning cup of coffee.
Those with high IQ had higher risk for psychological disorders (RR 1.20 - 223.08). High IQ was associated with higher risk for physiological diseases (RR 1.84 - 4.33). Findings lend substantial support to a hyper brain/hyper body theory.
Summary. Geniuses are both born and made. While genetics can explain up to 75% of variations in IQ levels, factors like socioeconomic status and home environment decide whether a person achieves their full genetic IQ potential.

The minimum accepted score on the Stanford–Binet is 132, while for the Cattell it is 148 and 130 in the Wechsler tests (WAIS, WISC).
Bill Gates
Now, the billionaire Microsoft co-founder gets at least seven hours of shut-eye, and wrote that all people need that much, “even if you've convinced yourself otherwise.”
Leonardo da Vinci's sleep schedule included 20-minute naps every four hours. Da Vinci followed an extreme form of a polyphasic sleep schedule called the Uberman sleep cycle, which consists of 20-minute naps every four hours.
On average, he gets between four and five hours of sleep per night. Want to know how he manages? Keep reading to find out more about Donald Trump's sleep schedule.
There are some family effects on the IQ of children, accounting for up to a quarter of the variance. However, adoption studies show that by adulthood adoptive siblings aren't more similar in IQ than strangers, while adult full siblings show an IQ correlation of 0.24.
Are smart people more likely to have smart kids? Yes. IQ is mostly genetic/hereditary, and the environmental factors early on that can decrease IQ are generally not an issue for smart couples, as they know (and can likely afford) good nutrition and safe housing practices.
It was concluded, among many other things, that identical twins are about 85 percent similar for IQ, whereas fraternal twins are about 60 percent similar. This would seem to indicate that half of the variation in intelligence is due to genes.
In addition to slowing down physically, most people lose points on intelligence tests as they enter their golden years. Now, new research suggests the loss of certain types of cognitive skills with age may stem from problems with basic sensory tasks, such as making quick judgments based on visual information.
