Health And Its Failure

Key Notes:

🌟 What is Health?

  • Health is a state of complete physical, mental, and social well-being — not just the absence of disease.
  • A healthy person can perform daily tasks efficiently and enjoys a good quality of life.

✅ Good health depends on:

  • Balanced diet
  • Clean environment
  • Personal hygiene
  • Regular exercise
  • Mental well-being
  • Proper rest and sleep

🔍 Factors Affecting Health

1️⃣ Genetic factors — Inherited traits may make a person prone to certain diseases.
2️⃣ Environmental factors — Clean air, water, and surroundings are crucial for good health.
3️⃣ Lifestyle choices — Unhealthy habits (like junk food, smoking, lack of exercise) lead to poor health.
4️⃣ Economic status — Access to healthcare, nutrition, and living conditions affects overall health.
5️⃣ Social factors — Support from family and friends contributes to mental well-being.

🤒 What is Disease?

  • Disease = A condition where the body or mind doesn’t function properly.
  • Signs are visible (e.g., rash, swelling), while symptoms are felt (e.g., pain, fatigue).

🔥 Types of Diseases

✅ 1. Acute Diseases

  • Short-term (e.g., cold, flu)
  • Quick recovery
  • Usually doesn’t affect long-term health

✅ 2. Chronic Diseases

  • Long-term (e.g., diabetes, heart disease)
  • May last a lifetime
  • Affects daily life and overall health

✅ 3. Infectious Diseases (caused by pathogens like bacteria, viruses, fungi, parasites)

  • Examples: Malaria, Tuberculosis, COVID-19
  • Spread through: air, water, food, contact, insects

✅ 4. Non-infectious Diseases (caused by genetics, lifestyle, or environmental factors)

  • Examples: Cancer, diabetes, heart disease, deficiency diseases (e.g., scurvy from lack of Vitamin C)

🛠️Causes of Disease

1️⃣ Pathogens — Bacteria, viruses, fungi, parasites
2️⃣ Deficiency — Lack of essential nutrients (e.g., anemia from iron deficiency)
3️⃣ Genetic factors — Inherited disorders (e.g., hemophilia)
4️⃣ Environmental factors — Pollution, unsafe water, radiation
5️⃣ Lifestyle choices — Smoking, poor diet, lack of exercise

💪Prevention and Maintenance of Health

✔️ Balanced diet — Include carbs, proteins, fats, vitamins, minerals, and water.
✔️ Hygiene practices — Wash hands, clean food, maintain personal cleanliness.
✔️ Vaccination — Protect against infectious diseases.
✔️ Exercise and rest — Boosts immunity and supports mental health.
✔️ Clean environment — Access to safe drinking water, sanitation, and fresh air.

🎯Why Do We Fall Ill?

  • Poor nutrition — Weakens the immune system.
  • Unhygienic conditions — Spreads infections.
  • Lack of rest and exercise — Weakens the body.
  • Mental stress — Affects both physical and emotional health.
