What is Mental health? Mental health includes our emotional, mental, and social well-being. It affects how we think, feel and act. Mental health is about how we manage our emotions.. Having good mental health doesn’t mean being happy all the time. Life is challenging for many of us: we face unemployment, poverty and hardship. When we take care of our mental health, we are better able to cope with the stresses of daily life, manage our emotions and make healthy choices.
