The expectation is for sleep to affect productivity, but I don't find that to be the case. Instead, I find that it has a lot of impact on my social and emotional well being rather than my productivity.
Productivity doesn't lead to many positive states - just exhaustion. Being well rested on the other hand has led to lots of positive mental conditions - surplus energy after work, dramatic decrease of negative thoughts, positive attitude towards new things, willingness for social activities, more boldness and confidence, and all these things snowball off of each other.
Hint: work from home, start at 7am, finish at 3pm, switch work phone off, do whatever you want afterwards, perhaps going outside to catch some sun, some sport and meet similarly minded people; that would do wonders both for your productivity and happiness. Sometimes I think the usual 9-5 was designed to damage everyone to be easier to control and with no energy to do anything threatening to whoever has the illusion of being powerful.
For me, my productivity depends om my emotional well being. When I have a positive attitude, I'm way more productive.
When I don't get enough sleep (kids... ;)), I'm a bit grumpy/negative during the day and I get nothing done. When I'm well rested, I'm super positive, happy, and can get work done effortlessly.
