Everyone is different, and not all things are equally beneficial for all people. Some people feel better just relaxing doing nothing while others need more activity and more excitement or stimulation to feel better. The most important thing is to find activities that you enjoy and that give you a boost. Do more exercises, spend more time in contact with nature and be with the people we love are the main activities that can be as effective as medication in treating a variety of mental illnesses, including depression and anxiety, according to a study at the University of California, USA.
