The WHO defines health determinants as the factors that influence the health status of a population. These factors include genetics, environment, lifestyle, and social and economic conditions. The health care system is not considered a determinant of health, but rather a means of addressing health problems.

Health promotion aims to improve the overall health and well-being of individuals and communities by preventing disease, improving quality of life, and reducing healthcare costs.

Health promotion interventions are actions or programs designed to improve health and well-being. Examples include vaccination, smoking cessation programs, healthy eating campaigns, and physical activity promotion programs.

Tobacco use is the leading cause of preventable death worldwide, responsible for over 8 million deaths each year.

Chronic diseases are long-lasting conditions that cannot be cured, but can be managed. Examples include heart disease, cancer, stroke, and diabetes. Influenza is an acute respiratory illness caused by a virus, and is not a chronic disease.

Vaccination, handwashing, and social distancing are all effective ways to prevent the spread of infectious diseases. Vaccination provides immunity to specific diseases, handwashing removes germs from the hands, and social distancing reduces the risk of contact with infected individuals.

A healthy lifestyle includes regular physical activity, a balanced diet, adequate sleep, and stress management. These factors contribute to overall health and well-being, and reduce the risk of chronic diseases.

Adults should get at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity each week, or a combination of both. This can be divided into smaller chunks of activity throughout the week.

A healthy diet includes plenty of fruits, vegetables, whole grains, and lean protein. Processed meats, such as bacon, sausage, and hot dogs, are high in saturated fat and sodium, and should be limited.

Adults typically need 7-9 hours of sleep per night to function optimally. Getting enough sleep is important for physical and mental health, and can help reduce the risk of chronic diseases.

Depression is the most common mental health disorder worldwide, affecting over 264 million people. It is characterized by persistent feelings of sadness, hopelessness, and loss of interest in activities.

Genetics, childhood trauma, and substance abuse are all risk factors for mental health disorders. Physical activity, on the other hand, is a protective factor that can help reduce the risk of mental health problems.

Exercise, meditation, and social support are all effective ways to manage stress. Exercise releases endorphins, which have mood-boosting effects, meditation helps to calm the mind and reduce stress hormones, and social support provides a sense of connection and belonging.

Health promotion and disease prevention can lead to reduced healthcare costs, improved quality of life, and increased productivity. It does not, however, lead to shorter life expectancy. In fact, it can help people live longer, healthier lives.

Individuals play a crucial role in health promotion and disease prevention by making healthy lifestyle choices, seeking preventive care, educating themselves about health risks, and advocating for policies that support health.
