What is mental health?


Mental health is a state of well-being in which a person understands 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.


Both physical and mental health are the result of a complex interplay between many individual and environmental factors, including:


  • family history of illness and disease/genetics
  • lifestyle and health behaviours (e.g., smoking, exercise, substance use)
  • levels of personal and workplace stress
  • exposure to toxins
  • exposure to trauma
  • personal life circumstances and history
  • access to supports (e.g., timely healthcare, social supports)
  • coping skills

When the demands placed on someone exceed their resources and coping abilities, their mental health will be negatively affected. Two examples of common demands are: i) working long hours under difficult circumstances, and ii) caring for a chronically ill relative. Economic hardship, unemployment, underemployment and poverty also have the potential to harm mental health.
