As someone who does I promise you: no you don't
I can already imagine the beautiful life I'm going to have if I only need to sleep 4-5 hours. Getting up at 4:30AM, brew some coffee and make breakfast, sit down at 5:00AM and code for like 3 hours. Then I'd workout a bit, take a shower and go to work.
My job is pretty demanding at the moment so I'd rather do the more interesting stuffs in the morning instead of after work (I usually arrive at home around 7pm so it's a bit tough).
Second, because while it might be more in a day, it's less overall (you'll die younger).
