Use your bed only for sleep
Your bed is surely the most comfortable place to work from home, with plenty of room to spread documents and electronics about. The temptation to read, work, talk on the phone, watch TV, or engage in other things in a comfy bed may be great.
However, if you work from bed, your brain starts to link your bedroom to work. This means that your brain won't cooperate when you try to go to sleep at night. Your brain will enter work mode because it now considers the bed as a place of work, which prevents you from sleeping. Though, use your bed just for sleeping. This makes it simpler to fall asleep by helping your brain build a stronger connection between your bed and sleep. Even though reading might help you unwind before bed, if it keeps your mind active, it can also keep you from falling asleep. Instead, try reading on the couch before going to bed.
