Q.(a) What are the steps to be adopted to lead healthy life style ? OR

(a) A healthy lifestyle rests on balanced nutrition, exercise, rest, hygiene, avoidance of harmful substances, stress management, timely vaccination and regular medical check-ups. (b) The secondary immune response, unlike the primary response, is faster, stronger and IgG-dominated because it is driven by immunological memory cells generated during the first exposure.

(a) Leading a healthy lifestyle requires a combination of habits that support physical and mental well-being. A balanced diet, containing adequate proportions of carbohydrates, proteins, fats, vitamins and minerals, provides the body with the nutrients needed for growth, repair and immune function, while avoiding excess/junk food helps prevent lifestyle diseases such as obesity, diabetes and cardiovascular disease. Regular physical exercise strengthens the cardiovascular and musculoskeletal systems, helps maintain ideal body weight, and improves mental health. Adequate sleep and rest allow the body to repair and regulate itself. Maintaining personal hygiene (regular bathing, hand-washing, clean food and water) reduces the risk of infectious disease. Avoiding harmful addictive substances - tobacco, alcohol and recreational drugs - prevents damage to the liver, lungs, heart and nervous system and reduces cancer risk. Managing stress through relaxation techniques, yoga, meditation or adequate leisure time protects both mental health and, indirectly, physical health, since chronic stress weakens immunity. Staying up to date with recommended vaccinations protects against preventable infectious diseases, and undergoing periodic health check-ups allows early detection and treatment of disease. Finally, avoiding self-medication and instead consulting a qualified doctor for illness, and following prescribed treatment/precautions correctly, helps prevent complications such as antibiotic resistance.
