If you’re feeling sore and achy, you can get some relief by adjusting the lighting in your environment. Specifically, turn on more lights during the day, and turn off ALL lights at night. When the Cleveland Clinic did that in a hospital, patients recovering from illness and surgery experienced significantly less pain and were more optimistic. It works because exposure to bright light during the day, and absolute darkness at night resets our inner body clock. That, in turn, cuts inflammation and boosts energy – and those are two key elements when it comes to decreasing pain and negativity.
