Human Health and Disease Class 12
Human health is a state of physical, mental, and social well-being, and the absence of disease or infirmity. However, disease is an abnormal condition or disorder that affects the functioning of the body or mind, causing pain, discomfort, and a decline in overall health. Human health and disease are closely related and influenced by various factors, including genetics, lifestyle, environmental conditions, and access to healthcare.
Many factors can influence human health, including genetics. Some diseases have a genetic basis, such as cystic fibrosis, sickle cell anemia, and Huntington’s disease. Inherited genetic disorders can be passed down through generations, and they can cause a range of symptoms and health problems. Genetic testing can help identify these disorders, and early intervention can help manage symptoms and prevent complications
Human Health and Disease Class 12 Lifestyle factors such as diet, exercise, and stress management also play a critical role in human health. A balanced and nutritious diet, regular exercise, and proper sleep are essential for maintaining optimal health. Conversely, unhealthy habits such as smoking, excessive alcohol consumption, and a sedentary lifestyle can increase the risk of various diseases, including cancer, heart disease, and diabetes.
Environmental factors such as pollution, exposure to toxins, and infectious agents can also impact human health. Air pollution, water pollution, and exposure to hazardous substances can cause respiratory problems, neurological disorders, and cancer. Infectious diseases such as tuberculosis, malaria, and HIV/AIDS are caused by viruses, bacteria, or parasites and can spread rapidly through populations.
