Well this shouldn't be a surprise to anyone who has been following what others have mentioned is a best practice for working from home: Set work boundaries, both in terms of time and physical location, as to what constitutes work and what is otherwise personal/family time.

Enforce set hours as to when you are actually working as opposed to when you are doing something else, and let others in your household know what they are. Create a separate physical environment that you can mentally associate as being where you perform work, and work only, and take any other activities such as social life and games out of it -- preferably using a different computer altogether.

Setting virtual walls where work begins/ends can greatly reduce the cognitive overhead your brain has to endure when trying to separate what is work from the rest of your life, and thus lower overall stress.
