Mental health refers to a state of well-being where one can cope with stress and work productively. Mental well-being involves having positive thoughts and feelings and managing challenges. Good mental well-being means feeling confident, maintaining relationships, having purpose, and coping with stress, while low mental well-being can be a warning sign of developing mental health conditions like anxiety or depression over time. Maintaining mental health is important so one can regularly relax, build coping skills, engage in self-care activities, manage emotions, and adopt a proactive mindset towards well-being.
