Intelligent people prefer to live at night and find it more difficult to sleep.

Intelligent people are also more likely to suffer from insomnia.

Research from Semmelweis University detected correlations between a person's sleep preferences and his or her IQ score..

Are those who live at night smarter?

The most intelligent individuals tend to prefer nightlife, when their creativity reaches its zenith. It is for this reason that these people tend to go to bed later or have trouble falling asleep.

Although different researches have warned that sleeping too little sleep has very harmful consequences for health and can even shorten life, the truth is that there is a relationship between a high IQ level and insomnia. insomnia.

Rest and sleep times play an essential role in the biology of animals, and this new study provides new variables to consider: sleep patterns and rest schedules are linked to their cognitive ability.. As the results show, subjects with higher IQ scores tend to be more active during the night, while those with lower scores tend to go to bed earlier.

Research on sleep cycles and intelligence

The truth is that this type of research always generates controversy. Many analysts agree that the concept of IQ used to measure a concept as abstract and relative as human intelligence is in itself a basic limitation. There is no doubt, however, that the night has certain characteristics that attract certain types of personalities, such as reflective people and those who develop their creative potential; profiles that demand the comfortable and mystical atmosphere that the night provides..

Robert Bolizsone of the authors of the research, showed through encephalogram images during sleep episodes, that there are certain variables that are directly associated with cognitive performance in the waking state. On the other hand, the research of H. Aliasson revealed how sleep intervals correlate with students' academic performance.

The correlation between intelligence test scores and sleep schedules is remarkable.

Other interesting studies on this subject are those carried out by the researcher Satoshu Kanazawa at the London School of Economics and Political Science. Kanazawa noted that there are significant differences between sleep schedule predilections in reference to their scores on IQ tests..... Subjects with higher scores reported a greater aptitude to produce during the night, while people with more limited IQ levels limited their activities during the day.

As Kanazawa indicates, prehistoric humans lived and produced mainly during the day, although the trend was reversed, increasing nocturnal activity as generations passed. It is from this point of view that it seems accurate to say that the evolution of the human psyche seems to be progressively linked to nighttime schedules.. In summary, Kanazawa agrees that people with higher cognitive abilities tend to feel more comfortable in furthering their personal development in the evening hours, showing a "higher level of cognitive complexity".

Night people and mental health

Another research carried out in 2008 and coordinated by the Italian psychologist Marina Giampietro noted that nocturnal people have a weaker emotional emotional stability and are more prone to suffer from depression and addictions.. This would confirm that minds with a greater capacity for creation and less traditional are in turn the most fragile to certain psychological disorders.
