We know that having a dedicated sleeping space contributes to the quality of sleep, but there are no studies on the size and boundaries required to create that space.

Using the bed as a workspace means you're bringing your work with you to bed. You completely erase any possibility of separation between workspace and sleep space.

With only one bedroom available, your only way to assign a dedicated sleeping space is to use your bed to sleep and a desk to work.

Throwing in some anecdotal opinion, I live in a studio style open apartment and have no issue sleeping well in my bed even if I can see my workspace. I however had issues sleeping back when I lived in a smaller apartment and used the bed as my main computer space.

Is it objectively better or worst? There's no study backing either theories. However, I believe that even working on a small desk next to your bed would be better than working directly from the bed. Otherwise you'd be effectively training yourself to think about work while lying down in the comfort of your sleeping area, instead of training yourself to fall asleep and relax.

I think all of this is overemphasizing how much we are subconsciously "training" our bodies to do anything.

As with most human behavior studies, I have yet to see a sleep study that managed to satisfactorily demonstrate causality in place of correlation when it comes to working in bed ruining your quality of sleep.

In this particular case, you could imagine that people who work from their bed tend to be on screens in their bed until just before bedtime, causing them to be more "wired" than people who have a dedicated office space and avoid screens in their bed entirely.
