Blog With Me Daily; Early Bird or Night Owl...Which bird are The Early Bird
The studies that say evening types are less reliable and stable, but that could be the result of night owls trying to fit the early bird way of life!
- Scientists from the University of Bologna infer that early birds are more conscientious people.
- A 2008 study by psychologist Marina Giamnietro et al. indicates evening-people tend to be less reliable, less emotionally stable and more apt to suffer from depression, addictions and eating disorders.(1) (From a personal perspective, “doh!”)
- The American Psychologist Association agrees that ‘morningness’ is associated with greater positive emotions in all age groups.(6) Measuring happiness is subjective, but it does show ‘morningness’ is associated with positive emotions.
- Published in the Journal of Applied Social Psychology, Christopher Randler, a professor at the University of Education in Heidelberg, Germany reported that early birds are more proactive than evening people, and so they do well in business. “They tend to get better grades in school, which gets them into better colleges which then leads to better job opportunities. Morning people also anticipate problems and try to minimize them. They’re proactive,” he says.(6)
Let’s see what the night owls have to say about that.
The Night Owl
- Research by Satoshi Kanazawa et al. at the London School of Economics discovered significant differences in sleep preferences, and found that people with higher IQs are more likely to be night owls. They found an evolutionary shift from being active in the day towards nightly pursuits and that those individuals who preferred to stay up late demonstrated “a higher level of cognitive complexity.”(2)
- Researchers from Belgium and Switzerland studying sleep habits found that early risers needed more rest than their nocturnal counterparts and didn’t focus as well later in the day as those who slept in.(2)
- Functional MRI studies were used to judge homeostatic sleep pressure- the body’s need for sleep- in night owls and early birds. The morning birds woke up between 4 and 5:30 a.m and went to bed by 9 p.m. The night owls went to bed at 3 or 4 a.m. and rose at noon.
- In the night owls, increased activity was seen in two parts of the brain at 10.5 hours that are involved in regulating the circadian signal. Essentially, the circadian signal was winning out over the pressure to sleep.
- For the early birds, on the other hand, “the sleep pressure prevents the expression of the circadian signal,” so those individuals were less able to keep their attention focused, says study coauthor Philippe Peigneux. The study is the first to show that circadian rhythms and sleep pressure interact to govern behavior.(4)
Which Bird Are You?
- The early birds also felt sleepier and didn’t react as quickly during tasks. Researchers say early birds could be more sensitive to sleep pressure than night owls. (5)
