Most morning people are found to have brighter dispositions as compared to night owls. Just being a morning person usually gives one a feeling of being healthy, which in turn increases the chances of positive emotions. Possible reasons for this can be that, human society is more favorable towards morning people than night owls. Also, greater exposure to natural light is a known mood-enhancer, which is why early birds are less prone to depression.
A study of college students at a Texas university in 2008, found that morning-type students scored significantly higher GPAs than night owls. This is likely to happen because morning students sleep earlier, avoid nighttime distractions, and wake up earlier, thereby finding more time for studies and classes.
Morning People Are Less Prone to Addictions
Substance abuse and other addictions such as social media, games, watching movies, etc., are more attributed towards night owls. Due to their sleep patterns, morning people are exposed to objects of addiction much lesser, thereby keeping them safer and healthier physically and mentally.
