> I find I'm more productive at certain types of tasks (including programming related ones) when I have a certain level of fatigue. For me, reaching that fatigue means going to the gym. I feel like the physical fatigue helps me to get into a form of mental focus and tranquility. Even though I usually hit the gym at 8PM and return circa two hours later, I can keep pushing code for at least three more hours. I also play competitive video-games with my friends, who keep on saying that they play better during the nights. Most of them are not into sports, but they can still say to be mentally more focused. Whilst I cannot really prove that I would produce better code during the nights, the matchmaking in the games do turn out to have a trend of win streaks. I succeeded to rank myself to the fourth topmost ELO pool by playing during mere midnights. To reach that rank from the previous one, it requires approximately 12 wins in a row, which is not an easy feat. About the original post, I also reason staying up late because the time difference between US and my current residency is such that any Github issues, PR's or emails tend to be sent at about midnight my local time. By staying awake an hour or two more, I can deal with those tasks to wake up to a less busy day.
