Lifestyle is a concept that encompasses many aspects of our behavior, from the pursuit of our interests and fashion choices to our status in our work, community, family, and culture. Our lifestyle is influenced by the way we treat others and the way we treat ourselves, and the way we perceive ourselves and our environment. We may be able to identify the lifestyle of another person or an object of desire based on their lifestyle or appearance. A lifestyle is a way of life influenced by various socio-economic, political, cultural, and religious contexts. It is the set of common characteristics and expectations for living that makes up an individual's character. A lifestyle is a unique expression of a community and can be influenced by a person's place of residence. Despite the known health benefits of a healthy lifestyle, a small proportion of the population adheres to a healthy lifestyle. Few people recognize the link between lifestyle and health, even though it is a key contributing factor to the emergence of chronic diseases. This is partly due to the fact that a healthy lifestyle is personal - a person's lifestyle is a reflection of his or her socio-economic, social, and cultural identity. Lifestyle has a huge influence on both mental and physical health. Lifestyle is associated with genetic disorders and consanguinity, which means that the lifestyle chosen by one person may have a significant effect on their children. Reforming unhealthy lifestyle practices may prevent genetic diseases from developing. The use of drugs for health-related conditions is common in Iran.
