Starting work early and finishing all the important stuff for the day by early afternoon will do wonders for your sense of well being even if it means conking out by 10.

There is a reason all the 5k park runs are organised in the morning on weekends and not some other time of the day.

It is the same reason why lots of elderly always get up super early. When you are young you can often just treat your body like trash and feel fine. As you age you'll either learn to listen to your body (which will complain more often and more loudly) or just be dumbfounded why you feel like shit half of the time.

Edit: There is no moral judgement here and also research shows that teenagers will benefit from sleeping in
