Mental health refers to the cognitive aspect of health. Often mental health is linked to or includes emotional health, I want to distinguish the two. Mental health is more the functioning of the brain, while emotional health refers to the a persons mood often connected to their hormones. Mental health then includes many mental health issues such as Alzheimers and dementia. It refers to the persons ability to use their brain and think. This may be to solve problems or to recall information, but the focus is on the cognitive aspect of the person.

Mental healthcare affect the other dimensions of health. An increase in mental health can come as a result of increased physical activity, and good mental health can then lead to an increase in self esteem as mental performance improves. Greater self esteem then leads to more confidence in social situations and can lead one to ask the larger questions about life leading to increased spiritual health.
