Health is defined as the quality of life that a person has acquired through his or her life and is characterized by the absence of infirmity and sickness. The term ‘health’ comes from the Greek words ‘kathos’polis’, which means the state of being healthy. Health is also an important aspect of human life in its relationship to physical, psychological and social well being where infirmity and illness are absent.
The definition of health has also changed over time in order to deal with medical conditions. Previously, only conditions of illness were the focus of our attention and it was seen as abnormal that the person with the medical condition did not live a normal life and there was no improvement. On the other hand, today there is much more focus on preventive care.
The definition of health includes all the aspects of one’s life – mental, physical and emotional – that is, physical, mental, emotional, social and ecological elements of the life of a person. This approach gives a more holistic view of health and a deeper understanding of why it is important.
Health has a variety of aspects that affect one’s life expectancy. These include the general health status, the quality of health and the frequency and severity of symptoms and diseases. The factors that are responsible for a person’s health status can be determined through diagnostic testing, clinical assessment, research, and the application of scientific theories.
The study of mental health is becoming an important area of health care. Mental health includes disorders of thought, behavior, and emotional processes. Mental health conditions can be life threatening and are often difficult to treat. They can also lead to a low quality of life, poor emotional functioning, and depression.
Emotional problems such as depression, stress, anxiety and other related disorders can be very detrimental to overall health. Emotional problems such as mental illness can also lead to the development of diseases such as cancer, heart attack, and diabetes. Therefore, understanding the causes of emotional problems is critical in helping to improve the quality of one’s life.
Stress is one of the most serious factors that affects life expectancy. In fact, stress is probably the main cause of disability, death and morbidity due to age-related diseases. Therefore, stress has a huge impact on health.
Stress can come about from the inability to get the right information, the fear of failure, the inability to meet deadlines, or even from a relationship that does not suit you. Stress is a powerful enemy. So, understanding the reasons behind stress is necessary to address this potential health threat.
Life expectancy is a measurement of how long a person lives in general and it also gives a good indicator of his/her quality of life. For example, a person who has a longer life expectancy would usually have a better quality of life. The length of life can be affected by health conditions, stress, diet and lifestyle, and other factors.
