Health is a condition of mental, physical and social well being where infirmity and illness are absent. The human being needs to be healthy in order to live a productive life, to enjoy his qualities and to avoid pain and suffering. However, the condition of health is an elusive concept. There is no direct relationship between health and wealth, but it is better to stay fit to avoid ill health and to lead a happy and meaningful life.
The next aspect of health is mental health, which is a condition of mind that includes the four broad elements of memory, information processing, perception and behavior. According to the third definition, “a state of mental or emotional well-being that is maintained by a balance of thought, emotion, knowledge and motivation.” Mental health is related to the capacity to learn, to think critically, to solve problems, to organize and plan and to cope with changes. The fourth element is reflection, which means the ability to identify and describe feelings, thoughts, and emotions, memory, information processing and behavior. According to the fourth definition, “a state of total well-being”.
Emotional health can be described as three aspects: psychological stress, anxiety and mood disorders. Psychological stress can be caused by factors such as work, relationship, peer and family problems and it can lead to physiological changes such as fatigue, weight gain, insomnia, depression, dizziness and anxiety. Anxiety and mood disorders can be caused by biological, neurological and environmental factors. However, biological and neurological factors are far from being the only ones because some diseases like heart diseases also lead to changes in the levels of the other psychological factors such as the self-esteem and the ability to make rational decisions.
