Description:BACKGROUND
Field of the invention
[001] Embodiments of the present invention generally relate to a system for analyzing stress and particularly to a system and method for analyzing stress of a psychiatric user.
Description of Related Art
[002] Mental health is more than simply a term for a person's psychological and emotional well-being. Rather, it's a condition of psychological and emotional well-being in which a person can use their cognitive and emotional capacities to fulfill everyday demands and perform social tasks. There is no single "official" definition of mental health, according to World Health Organization (WHO). As a result, numerous variables influence how mental health is defined, including cultural variations, conflicting professional theories, and subjective judgments. Furthermore, many specialists believe that mental disease and mental wellness are not mutually exclusive terms. In other words, the absence of a recognized mental disease is not always an indication of mental wellness.
[003] Looking at how efficiently and successfully a person performs is one approach to think about the mental health. So, there are things like feeling competent, capable of handling regular stress levels, as well as sustaining meaningful relationships and enjoying an autonomous life. This also involves the ability to recover from bad experiences and bounce again. Mental illness and stress do not imply that one is insane, and it is not anything to be embarrassed about. Our culture must adjust its attitude about mental disease and dysfunction. Mental illness and stress are characterized by changes in mood, aberrant thinking, and behavior, among other things. Mental illness and stress are commonly induced by workload and other personal and professional life factors, but they can also be triggered by a reaction to a traumatic event. Many studies have discovered that the mental illness and stress can be caused by hereditary causes, physiological imbalances, child abuse or trauma, socioeconomic deprivation, poor physical health, and other reasons.
[004] Regardless of these factors, mental illness and stress can be treated. One can always seek help from specialists in this field, or can simply conquer this condition by maintaining a good mindset and making lifestyle changes. Regular physical routines such as morning walks, yoga, and meditation are effective treatments for mental illness and stress. Apart from all of this, a healthy diet and adequate sleep are essential. A person can easily avoid the mental illness and stress by taking care of himself or herself, which can be accomplished by soothing the mind with peaceful music, being more sociable, and taking care of the body.
[005] There is thus a need for a system that can analyze stress of a psychiatric user in a more efficient manner.
