Mental health is defined by the World Health Organization as “a state of well-being in which an individual realizes his or her own potential, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to her or his community”. Research reveals that environments can increase or reduce our stress, which in turn impacts our bodies. What you are seeing, hearing, experiencing at any moment is changing not only your mood, but how your nervous, endocrine, and immune systems are working.
