woah cool infographic (Move your mouse to reveal the content) woah cool infographic (open) woah cool infographic (close) Science Says that whether you're a "Night Owl" (a person who feels more wakeful and productive during the night) or a "Day Lark" (a person who feels that way during the day) isn't a thing you can completely manipulate with coffee and alarm clocks; it's in your DNA! TLDR for people who dun wanna read the article: Humans have a "circadian rhythm" which tells their bodies when to shut down and rest, and when to be alert and active. For most humans, they are alert and active during the day, which is why businesses etc. are open during the day and closed at night. This rhythm is coded into humans genetic structures, and even though you can manipulate it to a certain degree, each person is going to have a natural sleep-wake cycle that their body will revert to if you stop actively trying to be awake or sleepy at certain times. Neither being a night owl or a day person is inherently better for you, by the way. So long as you get enough sleep, eat and drink properly, and generally take care of yourself, there's nothing wrong with being a creature of the night (of course, you may have to take some vitamin supplements to make up your lack of sun). In terms of productivity, both team Owl and team Lark (does anybody actually say that? I like it but I've never heard it before researching this) have advantages Night-workers: Get peace and quiet since most of the world is sleeping Tend to be more creative and outside-the-box thinkers Have less distractions around them Day-workers: Have lots of waking people available for help and collaboration Can use business services Natural light is better for the eyes So which team are you on? Or maybe you're halfway between?
