You should only use your bed for two things, and working isn’t one of them. Even if you your partner has already occupied the kitchen table for their important zoom meeting, find someplace else. It might feel nice and cosy to cuddle under your blanket in bed with your laptop, but don’t do it.
Firstly, the ergonomics of sitting in bed are horrible. Everything is too soft and you are unable to sit with a straight spine. Secondly, you don’t want to associate your bed with working. If you do, you are setting yourself up for sleep problems. (And by the way, don’t watch TV in bed, either.)
Working with people in all kinds of situations, many of them trauma victims, I usually don’t give strict guidelines. But this is one of the few. Don’t ever work in bed.
