How to Maintain a Good Health?

WHO defines health as a state of complete physical, mental, & social well-being and not merely the absence of disease or infirmity. This definition has been subject to controversy, as it may have limited value for implementation. Health may be defined as the ability to adapt and manage physical, mental, and social challenges throughout life.


Achieving and maintaining health is an ongoing process, shaped by both the evolution of health care knowledge and practices as well as personal strategies and organized interventions for staying healthy.

• Diet: A healthy diet that includes a variety of plant- and animal-based foods offering nutrients to your body is an important way to maintain your personal health. Nutrients give you energy and keep your body running, help build and strengthen bones, muscles, and tendons, and also regulates body processes. Making healthy food choices is important because it can lower your risk of heart disease, cancer, and others, contributing to maintaining a healthy weight.
• Exercise: Physical exercise enhances or maintains physical fitness and overall health and wellness. It strengthens muscles and improves the cardiovascular system. According to the National Institute of Health (NIH), there are four types of exercise; Endurance, Strength, Flexibility, and Balance. Endurance exercises are those that will elevate your heart rate including; walking, jogging, running, hiking etc.
• Sleep: Sleep is an essential component to maintaining health. In children, sleep is also vital for growth and development. Ongoing sleep deprivation has been linked to an increased risk for some chronic health problems. In addition, sleep deprivation has been shown to correlate with both increased susceptibility to, and slower recovery times from, illness.
• Role of Science: Health science is the branch of science focused on health. There are two main approaches to health science: the study and research of the body and health-related issues to understand how humans (and animals) function and the application of that knowledge to improve health and to prevent and cure diseases and other physical and mental impairments.
  The science builds on many sub-fields, including biology, biochemistry, physics, epidemiology, pharmacology, medical sociology. Applied health sciences endeavor to better understand and improve human health through applications in areas such as health education, biomedical engineering, biotechnology, and public health.
• Role of Public Health: Public health has been described as "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals." It is concerned with threats to the overall health of a community based on population health analysis. Public health has many sub-fields, but typically includes the interdisciplinary categories of epidemiology, biostatistics and health services. Environmental health, community health, behavioral health, and occupational health are also important areas of public health.
• Self-care Strategies: Personal health depends partially on the active, passive, and assisted cues people observe and adopt about their own health. These include personal actions for preventing or minimizing the effects of a disease, usually a chronic condition, through integrative care. They also include personal hygiene practices to prevent infection and illness, such as bathing and washing hands with soap; brushing and flossing teeth; storing, preparing and handling food safely; and many others.
  The information gleaned from personal observations of daily living – such as about sleep patterns, exercise behavior, nutritional intake, and environmental features – may be used to inform personal decisions and actions as well as clinical decisions and treatment plans.
