A recent study looked into the connection between “a person’s daily rhythm and activity levels during both wake and sleep” and human intelligence. The study found that morning people “tend to have superior verbal ability,” contrary to what was previously believed. Dr. Stuart Fogel explains that whether someone is a morning or night person can depend on their chronotype and their age. “A person’s chronotype is related to when in the day they prefer to do demanding things, from intellectual pursuits to exercise. Young individuals are typically ‘evening types’ while older individuals and those more regularly entrenched in their daily/nightly activities are likely ‘morning types’.”
Ultimately, “Our brain really craves regularity and for us to be optimal in our own rhythms is to stick to that schedule and not be constantly trying to catch up.”
