Introduction to Health

  • Health: State of complete physical, mental, and social well-being. Not just absence of disease.
  • Dimensions of Health: (1) Physical health, (2) Mental health, (3) Social health, (4) Spiritual health.
  • Determinants of Health: (1) Genetics, (2) Environment, (3) Lifestyle, (4) Healthcare access.
  • Public Health: Health of population as a whole. Focuses on prevention and promotion.
  • Community Health: Health status of community. Influenced by social, economic, environmental factors.

Nutrition and Balanced Diet

  • Nutrition: Process of obtaining and utilizing food for growth, energy, and maintenance.
  • Balanced Diet: Contains all nutrients in correct proportions. Carbohydrates, proteins, fats, vitamins, minerals, water, fiber.
  • Macronutrients: Required in large amounts. Carbs (energy), proteins (growth), fats (energy storage).
  • Micronutrients: Required in small amounts. Vitamins (A, B, C, D, E, K) and minerals (Ca, Fe, I, Zn).
  • Malnutrition: Deficiency or excess of nutrients. Undernutrition (kwashiorkor, marasmus), overnutrition (obesity).
  • BMI (Body Mass Index): Weight (kg) / Height (m)². Normal: 18.5-24.9, Overweight: 25-29.9, Obese: ≥30.
  • Dietary Guidelines: Eat variety of foods, limit salt/sugar/fats, stay hydrated, regular meals.

Hygiene and Disease Prevention

  • Hygiene: Practices that maintain health and prevent disease.
  • Personal Hygiene: (1) Regular bathing, (2) Clean clothes, (3) Oral hygiene, (4) Hand washing, (5) Nail care.
  • Environmental Hygiene: (1) Clean surroundings, (2) Proper waste disposal, (3) Safe water, (4) Pest control.
  • Food Hygiene: (1) Wash hands before eating, (2) Cook food thoroughly, (3) Store food properly, (4) Avoid contaminated food.
  • Mental Hygiene: Stress management, adequate sleep, positive thinking, social support.
  • Benefits: Prevents infections, improves quality of life, boosts immunity.

Common Health Problems

  • Communicable Diseases: Spread from person to person. Examples: Tuberculosis, Malaria, HIV/AIDS, COVID-19.
  • Non-communicable Diseases: Not infectious. Examples: Diabetes, Hypertension, Cancer, Heart disease.
  • Vectors: Organisms that transmit diseases. Mosquitoes (malaria), Houseflies (cholera), Rats (plague).
  • Prevention: Vaccination, sanitation, vector control, healthy lifestyle.
  • Epidemics: Sudden increase in disease cases in population.
  • Pandemics: Epidemics that spread across countries. Example: COVID-19.

Immunity and Vaccination

  • Immunity: Ability of body to resist infections.
  • Types: (1) Innate immunity (natural, non-specific), (2) Acquired immunity (specific, develops after exposure).
  • Innate Immunity: (1) Skin barrier, (2) Mucus membranes, (3) Phagocytes, (4) Natural killer cells.
  • Acquired Immunity: (1) Active (after infection or vaccination), (2) Passive (antibodies from mother or injection).
  • Vaccination: Introduction of weakened/killed pathogens or toxins to stimulate immunity.
  • Types of Vaccines: (1) Live attenuated, (2) Killed, (3) Toxoid, (4) Subunit, (5) mRNA vaccines.
  • National Immunization Program: Vaccines for polio, BCG, DPT, measles, hepatitis, etc.
  • Herd Immunity: Protection of unvaccinated individuals when majority is vaccinated.
  • Diagram Importance: Diagram showing types of immunity and vaccination process is crucial.

First Aid

  • First Aid: Immediate care given to injured or ill person before medical help arrives.
  • Principles: (1) Preserve life, (2) Prevent worsening, (3) Promote recovery.
  • Common Procedures: (1) CPR for cardiac arrest, (2) Heimlich maneuver for choking, (3) Bandaging for wounds, (4) Splinting for fractures.
  • Emergency Kit: Bandages, antiseptics, scissors, gloves, painkillers, thermometer.
  • Training: Learn from certified organizations like Red Cross.
  • Legal Aspects: Good Samaritan laws protect first aiders.
  • Diagram Importance: Diagrams of first aid procedures like CPR and bandaging are important.

  • Types: (1) Alcohol abuse, (2) Tobacco use, (3) Drug addiction (opioids, cannabis, cocaine).
  • Effects: (1) Physical (liver damage, cancer), (2) Mental (depression, anxiety), (3) Social (relationship problems).
  • Prevention: (1) Education, (2) Strict laws, (3) Rehabilitation centers, (4) Family support.
