Lifestyle constitutes a framework employed by individuals, collectives, and nations, shaped within distinct geographical, economic, political, cultural, and religious contexts. It pertains to the attributes of the inhabitants of a specific region during a particular temporal and spatial setting. This encompasses the quotidian behaviors and functions of individuals in their occupational, recreational, and dietary practices. A salutary lifestyle, which is typified by regular engagement in physical activity, maintenance of an optimal weight, abstention from smoking, moderate consumption of alcohol, and adherence to a nutritious diet, correlates positively with an enhancement in life expectancy (LE). Empirical studies have documented increases in life expectancy of 6.6 years for men and 8.1 years for women in Singapore; 8.8 years for men and 8.1 years for women in China; 10.3 years for men and 8.3 years for women in Japan; 12.2 years for men and 14.0 years for women in the United States; 16.8 years for men and 18.9 years for women in Canada; and between 7.4 to 15.7 years for three European cohorts (RCPH, ESTHER, and Tromsø), suggesting that the advantageous effects of a healthy lifestyle may exhibit variability across different populations and nations.
In recent decades, lifestyle has emerged as a significant determinant of health, garnering increased attention from researchers. According to the World Health Organization (WHO), 60% of factors related to individual health and quality of life are associated with lifestyle choices. A substantial number of individuals adhere to an unhealthy lifestyle. Consequently, they face various health issues, disabilities, and even mortality. Health complications such as metabolic disorders, musculoskeletal issues, cardiovascular diseases, hypertension, obesity, and violence may stem from an unhealthy lifestyle. The interplay between lifestyle and health warrants rigorous examination. The lifestyle variables that impact health can be classified into several categories:
Diet and Body Mass Index (BMI):
Diet serves as the most significant element of lifestyle and demonstrates a direct and positive correlation with health outcomes. A poor diet and its repercussions, such as obesity, represent prevalent health concerns in urban populations. An unhealthy lifestyle can be quantitatively assessed through BMI. Urban lifestyles frequently contribute to nutritional challenges, such as increased consumption of fast foods and suboptimal dietary choices, exacerbating issues like cardiovascular diseases.
Exercise:
Exercise is integral to addressing general health challenges and is a fundamental component of lifestyle. Regular physical activity, in conjunction with a healthy diet, contributes to improved health outcomes. Numerous studies emphasize the association between an active lifestyle and enhanced levels of happiness.
Sleep:
Sleep constitutes one of the foundational elements of a healthy life. It is inextricably linked to overall wellbeing. Sleep disorders can lead to significant social, psychological, economic, and health-related consequences. Lifestyle choices may influence sleep patterns, and sleep quality, in turn, has a pronounced impact on both mental and physical health.
Sexual behavior:
The establishment of normative sexual relations is essential for a holistic and healthy existence. The dysfunctionality of sexual relations constitutes a prevalent issue across numerous societies, exerting a profound impact on both mental and physical well-being. It can be posited that dysfunctional sexual relations may precipitate an array of familial complications or sexually transmitted health conditions, such as AIDS.
Substance abuse:
Addiction is widely recognized as a manifestation of an unhealthy lifestyle. The consumption of tobacco and other substances may lead to a multitude of adverse health outcomes, including cardiovascular diseases, asthma, cancer, and neurological impairments. Recent research conducted in Iran indicates that 43% of females and 64% of males engage in the use of hookah. A longitudinal investigation reveals that 30% of individuals aged between 18 and 65 years are habitual cigarette smokers.Medication abuse: The misuse of pharmaceuticals is a prevalent issue in Iran and is categorized as an unhealthy lifestyle choice. Maladaptive practices regarding medication usage include self-medication, sharing prescriptions, utilizing medications without appropriate prescriptions, excessive prescribing of medications, dispensing high quantities of each drug, administering unnecessary medications, poor legibility in prescriptions, neglecting contraindicated drug interactions, overlooking the deleterious effects of medications, and failing to adequately inform patients about drug effects.

Application of modern technologies:
The advancement of technology serves to enhance the quality of human existence. However, the improper utilization of technology may yield detrimental consequences. For instance, engaging with computers and other electronic devices late into the night can adversely affect sleep patterns, leading to disturbances in sleep quality. Additionally, dependency on mobile phones has been correlated with symptoms of depression.
Recreation:
Leisure activities constitute an integral component of one’s lifestyle. The neglect of recreational pursuits can result in adverse repercussions. Through disorganized leisure planning and engagement in unhealthy pastimes, individuals may jeopardize their overall health.
Study:
Engaging in study is regarded as a vital exercise for the intellect. Incorporating academic pursuits as a facet of one’s lifestyle can foster enhanced physical and mental well-being. For instance, the incidence of dementia, including Alzheimer’s disease, is notably lower among individuals with higher educational attainment. Academic engagement has the potential to decelerate the progression of dementia.
A healthy lifestyle encompasses a multifaceted array of dimensions, including a balanced diet, regular physical activity, sufficient sleep, and the avoidance of deleterious behaviors, such as excessive screen time, among others. Safeguarding one’s body from the consumption of harmful substances, engaging in regular exercise, and maintaining proper nutrition and sleep are paramount elements that characterize a healthy lifestyle. Optimal fitness enables individuals to perform daily activities without experiencing lethargy, restlessness, or fatigue. An individual who is both healthy and fit possesses the capability to fully embrace life without encountering significant medical or physical challenges. In recent decades, a notable increase in the global average life expectancy has been observed. Nonetheless, the extent to which these advancements correlate with a comprehensive reduction in healthcare expenditures remains ambiguous. Investigations into the influence of a healthy lifestyle on healthcare costs have primarily concentrated on the effects of individual risk behaviors.
To promote a healthy lifestyle, the World Health Organization (WHO) advocates for the consumption of ample fruits and vegetables, the reduction of fat, sugar, and salt intake, and the incorporation of regular physical exercise. Individuals can assess their body mass index (BMI) based on their height and weight to determine if they are classified as overweight. The WHO offers a range of publications aimed at fostering and endorsing healthy lifestyle choices.
12 Steps to Healthy Eating (Recommended by WHO)
- Adopt a diet that is nutritionally rich, emphasizing a diverse array of foods predominantly sourced from plant origins rather than those derived from animal sources.
- Incorporate bread, whole grains, pasta, rice, or potatoes into your daily meals multiple times.
- Consume a wide range of vegetables and fruits, ideally fresh and locally sourced, on several occasions throughout the day, ensuring a minimum intake of 400 grams per day.
- Sustain body weight within the recommended parameters (with a BMI ranging from 18.5 to 25) through engagement in moderate to vigorous physical activity, preferably on a daily basis.
- Regulate fat consumption to not exceed 30% of daily caloric intake, while substituting the majority of saturated fats with unsaturated fats.
- Opt for plant-based proteins and lean sources of animal protein by replacing fatty meats and processed meat products with beans, legumes, lentils, fish, poultry, or lean cuts of meat.
- Utilize dairy products such as milk, kefir, sour milk, yogurt, and cheese that are low in both fat and sodium content.
- Select food items that are characterized by low sugar content, while consuming free sugars in moderation and restricting the intake of sugary beverages and confections.
- Adopt a low-sodium dietary regimen, with total daily salt consumption not surpassing one teaspoon (5 grams), inclusive of the salt contained in bread and processed, cured, and preserved items.
- The World Health Organization (WHO) refrains from prescribing specific limits for alcohol consumption, as the prevailing evidence suggests that complete abstinence from alcohol is the most beneficial for health; thus, lower consumption is preferable.
- Ensure food preparation adheres to safe and hygienic practices, utilizing methods such as steaming, baking, boiling, or microwaving to minimize added fat content.
- Advocate for exclusive breastfeeding for the initial six months, followed by the introduction of safe and nutritious complementary foods around the age of six months. Encourage the continuation of breastfeeding for the first two years of life.
Various lifestyle factors are very important for good health. These include proper diet, regular exercise, adequate sleep, stress management, and drinking the right amount of water. These are helpful in increasing our body's immunity and ensuring a healthy life in the long run.
