Mental Health

Mental health is “a state of well-being in which the individual realizes his or her own abilities, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to his or her community”, according to the World Health Organization (WHO). Mental health includes subjective well-being, perceived self-efficacy, autonomy, competence, intergenerational dependence, and self-actualization of one’s intellectual and emotional potential, among others.

Mental health includes our emotional, psychological, and social well-being. It affects how we think, feel, and act. It also helps determine how we handle stress, relate to others, and make choices. Mental health is important at every stage of life, from childhood and adolescence through adulthood.

The factors contributing to mental health are

  • Biological factors, such as genes or brain chemistry
  • Life experiences, such as trauma or abuse
  • Family history of mental health problems

Mental disorders are defined as the health conditions that affect and alter cognitive functioning, emotional responses, and behaviour associated with distress and/or impaired functioning.
