I found an article that might interest you.Do check it out here for further reading .
As for me, I'd just shut down all the 'machines' that surrounds me (phones,laptops etc) and just leave my studio for a brisk walk.I like walking at night, especially when it rains.There's a feeling cleanliness and tranquility during rain, that helps clear my mind. Even though i don't like humans, i'd still make it a point to occasionally engage them for conversations. I hate to admit it,but sometimes a little human interaction and silliness from people you talk to is refreshing to the brain. After all that, you go home,take a shower , put on your favorite monster movies and watch them till you fall asleep.You wake next day feeling like a rockstar.
If this doesn't work, go get an ice cream or a Mars bar.
