Visualize your happy place
Many people shy away from meditation because they think it involves sitting cross legged on the floor while heading into a trance.
Meditating doesn't have to be that hard. If you want to take a mental break and refresh your brain one of things you can do is visualize a place of peace that you love to go to. Close your eyes, slow your breathing down, relax your muscles and focus on that happy place. Keep at it until the outside noise fades away and you feel refreshed.
You can do this even with as little as 10 minutes.
