According to several studies, people that get up early are more in sync with the standard corporate schedule and tend to possess more proactive personalities, resulting in better grades at school or higher wages on the work. Waking up early has very benefits: When you wake up early, your body doesn't feel tired, you have more energy because you have higher chances of completing all stages of the required sleep cycles, get a sense of order in life or making you feel happier and creating a routine. Being an Early Bird rather than a Night owl helps you be productive during the day. Creating a routine and waking up early helps develop a more organized life and enjoy quality sleep. 1. https://www.bbc.com/worklife/article/20190213-is-waking-up-early-good-or-bad

TL;DR- Waking up early benefits you depending on what type of sleeper you are. Many successful people enjoy waking up late so what's more important than waking up early is getting enough sleep. People are convinced waking up early is the best way to be productive, but that may not be the case for everyone. Waking up early might not be ideal depending on what type of sleeper you are and what you consider early. Natural early birds may have an easier time waking up before sunrise, but others could become less productive doing so. [1] Many CEOs like Tim Cook from Apple and Pepsi CEO Indra Nooyi claim that waking up at 4:00 am is key to their success [1]. But testimonies from people who attempted to set their wake up time around 4:00 am or 5:00 am said it was “miserable,” and “fell asleep in their chair” [2]. You don't have to wake up early to be successful but it's good to keep a consistent sleeping pattern of 8 hours. With that being said, many successful people were known for their habit of snoozing late: Winston Churchill didn't get out of bed until 11:00 am, Box CEO Aaron Levie around 10:00 am, and Alexis Ohanian, founder of Reddit goes to bed around 2:00 am and tries to get up by 10:00 am [3].

TL;DR Waking up early is not universally good There's an argument that " early birds" are more productive than "night owls". However; if a "night owl" and a "early bird" work the same 9-5, 40 hour working week is it reasonable to expect that the person whose sleeping pattern is less accommodating to early starts does as well as the person whose is? According to Katherine Dudley for Harvard Health Publishing: "... a night owl type may be starting the day relatively “jet lagged” — feeling out of sync with their body due to being awake when the body would prefer to be asleep."(1) Though an early riser may have a higher capacity for planning and self direction; late risers may have a higher capacity for memory and openness to new experience . (2) There are benefits to both but an early morning start necessitated by working schedule risks diminishing the valuable qualities many later risers possess. 1. https://www.health.harvard.edu/blog/early-birds-may-be-more-active-but-night-owls-can-catch-up-2020110621261 2.https://www.bbc.com/worklife/article/20171114-why-you-shouldnt-try-to-be-a-morning-person https://www.theguardian.com/commentisfree/2015/oct/20/early-six-myths-sleep-workplace-school-college
