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.
