<–2/”>a >Human Health and diseases
According to the World Health Organisation (WHO), health is defined as:
Health is a state of complete physical, mental, and social well being and not merely absence of disease or infirmity.
Good health of an individual is important in order to ensure happiness and our ability to work. There are many factors which affect our health. Some of these factors like balanced diet, clean water and clean Environment have a positive impact on health while others such as disease causing organisms and unhygienic conditions have a negative effect on our health.
Balanced diet, personal hygiene and regular exercise are very important to maintain good health. Yoga/”>Yoga has been practiced since time immemorial to achieve physical and mental health. Awareness about diseases and their effect on different bodily functions, vaccination (immunization) against infectious diseases, proper disposal of wastes, control of vectors and maintenance of hygienic food and water Resources are necessary for achieving good health.
Disease :Disease is a malfunctioning process related to a certain part of the whole body in which normal functions are disturbed or damaged. Disease literally means not at ease
Disease may be the sickness of the body or the mind. A disease can be as mild as a sore throat, common cold, and stomach upset or as serious as cancer. Disease can strike almost any part of the body and anybody at some stage or the other. They can also affect a person‘s mental and emotional health.
Deficiency diseases :The diseases which occur due to deficiency of one or more nutrients (proteins,Carbohydrates, VITAMINS and Minerals) in our diet are called deficiency diseases.
The overall ability of the host to fight the disease-causing organisms, conferred by the immune system is called immunity. Immunity is of two types: (i) Innate immunity and (ii) Acquired immunity.
Innate Immunity :-Innate immunity is non-specific type of defence that is present at the time of birth. This is accomplished by providing different types of barriers to the entry of the foreign agents into our body.
Acquired immunity, on the other hand, is pathogen specific. It is characterized by memory. This means that our body when it encounters a pathogen for the first time produces a response called primary response which is of low intensity.,
Human health and diseases are a complex and ever-changing field of study. There are many different subtopics that fall under this umbrella, each with its own unique set of challenges and opportunities.
Anatomy is the study of the human body and its structures. It is a fundamental science that is essential for understanding how the body works and how diseases can affect it. Biochemistry is the study of the chemical processes that occur in the body. It is closely related to anatomy, and together they provide a comprehensive understanding of human physiology.
Bioethics is the study of ethical issues that arise in the field of biology. It is a relatively new field, but it has already had a significant impact on the way we think about and treat diseases. Biotechnology is the use of living organisms or their products to create new products or improve existing ones. It is a rapidly growing field with the potential to revolutionize many aspects of human health.
Clinical research is the process of testing new drugs and treatments in humans. It is a critical part of the development of new medical therapies, and it is essential for ensuring that these therapies are safe and effective. Epidemiology is the study of the distribution and causes of disease in populations. It is a key tool for understanding and preventing disease, and it is essential for planning and implementing public health programs.
Genetics is the study of genes and heredity. It is a rapidly growing field with the potential to revolutionize our understanding of disease and its prevention. Immunology is the study of the immune system and how it protects the body from disease. It is a critical field with the potential to develop new treatments for a wide range of diseases.
Microbiology is the study of Microorganisms, including bacteria, viruses, and Fungi. It is a fundamental science that is essential for understanding how diseases are caused and how they can be prevented. Nutrition is the study of how food affects health. It is a complex field that is essential for understanding how to maintain a healthy diet.
Pharmacology is the study of drugs and their effects on the body. It is a critical field with the potential to develop new treatments for a wide range of diseases. Physiology is the study of the functions of the human body. It is a fundamental science that is essential for understanding how the body works and how diseases can affect it.
Public health is the science and art of preventing disease, prolonging life, and promoting health through the organized efforts of Society. It is a critical field with the potential to improve the health of people around the world. Toxicology is the study of the harmful effects of chemicals on the body. It is a critical field with the potential to prevent exposure to harmful chemicals and to develop treatments for poisoning.
Virology is the study of viruses. It is a rapidly growing field with the potential to revolutionize our understanding of disease and its prevention.
These are just a few of the many subtopics that fall under the umbrella of human health and diseases. Each of these subtopics is a complex and fascinating field of study, and each has the potential to make a significant impact on the lives of people around the world.
