If you’re a night owl, it’s more likely that your intelligence level is higher than average. Scientists suppose this is due to brain activity being so high so that it challenges regular daily biorhythms.In a study published by Personality and Individual Differences magazine, a connection between a child’s intelligence and sleeping habits was studied in thousands of young people. It was found out that the majority of smart people love waking up later on both weekdays and weekends. Another similar research studied 400 recruits of US Air Force and resulted in similar conclusions.
