Since we receive most of information about the world through the eyes, what we are looking at is reflected in how we feel. Looking at uplifting, peaceful, and happy pictures can help to relax and rise above the everyday stress.
Watching a happy movie can totally change the way one feels because it affects the two most powerful senses: sight and hearing. But choose carefully what to watch - happy and peaceful movies will reduce stress, but violent and horror ones may increase it.
