We know that certain life-style factors can cause stress and may lead to diseases like cancer and coronary heart disease, yet we are unable to change our behaviour. Explain why?

Life-style is the overall pattern of decisions and behaviours that determine a person's health and quality of life. An individual, when stressed, is more likely to expose himself/herself to pathogens — agents causing physical illness.

Stressed individuals have poor nutritional habits, disturbed sleeping patterns, tendency to engage in health-risking behaviours such as intake of stimulants such as caffeine, alcohol, cigarettes, drugs like tranquil lies such health impairing behaviours develop gradually and provide pleasant experiences temporarily, but have detrimental long-term consequences.

As they are adductive, and pleasurable, individuals using these psychoactive substances are unable to give them up.

• Such type of life-style ultimately cause serious health hazards like cancer, diabetes and coronary heart diseases.

• Knowing that faulty lifestyle causes various physical and psychological hazards. Still people continue. Because the consequences and side effects are not likely to occur immediately. Their effects get manifested after several years. So people ignore them. Because they are aware with the side effects. They develop anxiety because of inconsistency in their attitude and behaviour but because this lifestyle becomes a part of their habit pattern. So they find it very difficult to change and continue such hazardous lifestyle and ultimately it causes a stage of burn out.
