What is health? Definition and History

Health is a state of complete physical, mental and social well-being, and not merely the absence of disease or infirmity.

World Health Organization

Health is a fundamental human right and the foundation for well-being and human development. Good health is central to human happiness and well-being. It also makes an important contribution to economic progress, as healthy populations live longer, are more productive, and save more money.

The concept of health has evolved over time. In the past, health was often defined simply as the absence of disease. Today, health is seen as a state of complete physical, mental and social well-being.

There are many factors that contribute to good health, including access to quality healthcare, healthy lifestyle choices, and a clean and safe environment.

Health is a complex and dynamic issue, and there is much more to it than simply the absence of disease. It is an important issue for everyone, and we all have a role to play in ensuring our own health and the health of those around us.


The history of health is a long and complicated one. It began with the earliest humans trying to find ways to prevent illness and injury. Over time, we’ve developed a better understanding of how the human body works and what causes disease. This has led to the development of vaccines and other medical treatments that have saved millions of lives.

Today, we continue to face new challenges when it comes to our health. But with the help of medical research and advances in technology, we are making progress in finding new ways to prevent and treat illness.


There are many ways to maintain good health. One of the most important things you can do is to eat a healthy diet. Eating a variety of fruits, vegetables, and whole grains will help you get the nutrients you need to stay healthy. Exercise is also important for maintaining your health. Getting at least 30 minutes of moderate exercise every day can help you stay fit and reduce your risk of developing chronic diseases.
