Key concepts: Health: The Ultimate Treasure (Class 8 Science)
This chapter is about protecting health — 'the ultimate treasure'. Good health comes from a balanced diet, exercise, hygiene and clean water, while missing nutrients cause deficiency diseases. Diseases are either communicable (spread by germs through air, water or food) or non-communicable (such as obesity, which do not spread). The immune system defends the body, and vaccines train it in advance to prevent disease. Antibiotics treat bacterial infections only — not viruses — and misusing them causes the dangerous problem of antibiotic resistance.
- Health
- A state of physical, mental and social well-being, not merely the absence of illness; it is kept up by good habits.
- Balanced diet
- A diet that supplies all the nutrients in the right amounts, with plenty of fruits and vegetables; it prevents deficiency diseases.
- Deficiency disease
- An illness caused by the lack of a particular nutrient in the diet, prevented by eating a varied, balanced diet.
- Exercise and hygiene
- Regular exercise keeps the body fit, and hygiene (like washing hands) and clean water stop the spread of germs.
- Communicable diseases
- Infectious diseases caused by germs that spread from person to person through the air, contaminated water and food, or worms.
- Non-communicable diseases
- Diseases that do not spread between people, such as obesity, which is linked to poor diet and lack of exercise.
- Immune system and immunity
- The body's defence system fights germs; immunity is the ability to resist a disease, including acquired immunity built after exposure.
- Vaccines
- Preparations that train the immune system to recognise and attack a germ, giving acquired immunity; they are preventive, not curative.
- History of vaccines
- Edward Jenner made the first vaccine against smallpox using cowpox; India had an earlier inoculation tradition and is now a major vaccine producer.
- Antibiotics
- Medicines that kill disease-causing bacteria by targeting parts of bacterial cells; they do not work against viruses or protozoa. Penicillin, discovered by Fleming in 1928, was the first.
- Antibiotic resistance
- When bacteria survive and multiply despite an antibiotic, caused by misuse such as taking antibiotics unnecessarily or not finishing the course — it makes infections harder to treat.
- Preventing disease
- Clean water, good sanitation, hygiene, a balanced diet and vaccination together keep communicable and deficiency diseases away.
