This research raises important questions about circadian rhythm. There are likely benefits and drawbacks to both chronotypes. In addition, shift workers are at a higher rate of many chronic diseases, which may be related to keeping late hours. Other studies have linked a night chronotype to risk taking behaviors and even tobacco use. Chronotypes and Healthīeing an evening person isn’t entirely beneficial. Evening types are also more likely to be extroverts and creative thinkers than morning people, who are generally linear thinkers and relatively introverted. However, night people are still more successful in their careers and also earn more money on average. Although night owls tend to be more intelligent, early risers, or morning larks, tend to perform better in school. In addition, there are key personality differences between morning larks and night owls. These intelligent people also rise later. In fact, people with high IQs tend to go to bed 50 minutes after their less intellectually gifted peers. One major finding of a recent study is that people who are more intelligent tend to be night owls. Chronobiology research has found that there are many differences between night owls and morning larks, even beyond their preferred time to doze. While these can be difficult to define, night owls tend to go to sleep much later and also rise later in the morning, while morning larks are early to bed and early to rise. The two most common chronotypes are known colloquially as the night owl and the morning lark. Over their lives, humans gradually fall into sleep-wake routines, known as chronotypes. By exposing ourselves to light at certain times and other behaviors, humans often end up with a daily schedule that is slightly different from their innate circadian rhythm. Humans also have this internal clock, but we are unique among animals in that we can modify our rhythms by choice. Nerve centers in the suprachiasmatic nucleus of the brain perceive light, which cues the body to release hormones and undergo a variety of cellular processes. The early bird may catch the worm, but a new study on chronotypes suggests that night owls are most intelligent.Īlmost all animals have some sort of circadian rhythm, or 24-hour biological clock.
