A study published in the journal Sleep Medicine Reviews found that there is a bidirectional relationship between sleep and intelligence, with better sleep promoting higher intelligence and higher intelligence promoting better sleep.
In a sample of 347 Brazilian university students, those in the 126+ range tend to sleep some 40 minutes more than the others. However, in a sample of 237 adults from the same area as the students, those with a higher IQ slept some 40 minutes less.
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.
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. Think about dreaming as sorting out all the things that you learn or think about during the day, somewhat like a processing plant.
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.
Tall signs of intelligence
The conclusion comes from a study of the DNA of 6,815 people. Of course, there are still people who are short and intelligent, plus those who are tall and dim. But, on average, there is a small association between being taller and having higher intelligence.
Those who reported more frequent daydreaming scored higher on intellectual and creative ability and had more efficient brain systems measured in the MRI machine. “People tend to think of mind wandering as something that is bad. You try to pay attention and you can't,” says Schumacher.
People with efficient brains may have too much brain capacity to stop their minds from wandering. A new study from the Georgia Institute of Technology suggests that daydreaming during meetings isn't necessarily a bad thing. It might be a sign that you're really smart and creative.
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.
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%).
Within broad genetic constraints, humans can choose what time to go to bed and when to get up. Sustained nocturnal activities seem to be largely evolutionarily novel. According to research, more intelligent children may grow up to be more nocturnal as adults than less intelligent children.
Most Geniuses Perfected the Power Nap
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.
Elon Musk says he's upped his sleep to 6 hours per night—and that his old routine hurt his brain.
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.
They read a lot
Because they're so curious, smart people are also inclined to be voracious readers, writes Cheikh Mbacke Diop. Indeed, many of the world's most successful people — Bill Gates and Oprah among them — say they educate themselves by reading anything they can get their hands on.
You're a Daydreamer
INFP author Edgar Allan Poe once said, “Those who dream by day are cognizant of many things which escape those who dream only by night.” As an INFP you relate to this quote wholeheartedly. Your imagination is the one place where you can be totally free.
I believe that out of the MBTI personality types that INFPs and INTPs daydream the most. INFPs are very creative and poetic daydreamers who have very rich and colorful emotional inner worlds. INTPs are logical precise innovators who can sometimes be found in a never-ending daydream.
Throw social commitments into the mix, and there's limited time to be alone and be still with your thoughts and creative process. It's common for people with genius qualities to seek out isolation at times, due to a social anxiety and an excessive need for “me” time, in order to practice mindfulness..
Curiosity: Highly intelligent People are curious about the world and want to learn more about how it works. Recognition of limitations: They can also recognize their limitations and admit that they don't know the answers. By doing this, they can keep exploring and finding answers.
Because they spend their time developing their curiosity, intelligent individuals stand out from the crowd. They geek out, ponder, research, and read. Whether the subject is the most recent catastrophic disaster, proper flossing technique, or how words have evolved, they will take the time to go further.
Most independent people enjoy independence. It is a source of strength for them. However, this trait can make it difficult for intelligent people to fall in love. Since they are incredibly independent, they see a partner not as someone who “completes” them but rather as a person to share moments with.
However, intelligence has drawbacks too. For example, studies have found that higher IQ is associated with more and earlier drug use. Studies have also found that higher IQ is associated with more mental illness, including depression, anxiety, and bipolar disorder.
Talking fast may make people appear more intelligent, although the evidence is mixed — research reveals if there are other advantages. According to research, you sound more intelligent if you speak relatively slowly.
