1. Physical inactivity and its effect on non-communicable diseases (non- infectious ) Name: Zahraa Eid Abdelrazek ID: 114182 Group: C – C6

2. The Silent Contributor to Global Health Crises This presentation explores how physical inactivity drives non-communicable diseases (NCDs) like heart disease and diabetes. With sedentary lifestyles rising globally, understanding this link is critical for prevention.

3. What is Physical Inactivity ? It’s failing to meet WHO’s minimum of 150 mins/week of moderate exercise (e.g., brisk walking). 1 in 4 adults worldwide are inactive High-income countries have double the inactivity rates of low-income ones.

4. We learn from the graph that : ‘‘Inactivity isn’t just laziness—it’s a systemic issue tied to urbanization, desk jobs, and screen time. Even small reductions in movement add up over time .’’

5. NCDs Linked to Inactivity Cardiovascular Diseases (CVDs):  30% higher risk in inactive adults . Type 2 Diabetes:  Inactivity reduces insulin sensitivity by 40 %. Obesity:  Burns 500+ fewer calories/day than active peers . Cancer:  20% higher colon/breast cancer risk Osteoporosis :  Weakens bones by 1-3% yearly post-age 30 . These diseases share biological pathways linked to inflammation and metabolic dysfunction from inactivity.

6. How does Sitting Kill Slowly? Inactivity Muscle Atrophy     Insulin Resistance Inflammation Key Point: Just 2 weeks of inactivity = ↑ blood sugar, ↓ muscle mass So, The body deteriorates rapidly without movement - even astronauts lose 1% bone density/month in zero gravity.

7. What 30 Minutes/Day Can Do Activity Biological Effect Brisk Walking ↓ Heart disease risk by 30% (coronary artery calcium scores) Strength Training ↓ Type 2 diabetes risk by 40% (improves GLUT4 glucose transporters in muscles) Yoga ↓ Cortisol (stress hormone) by 25% (measured in saliva samples) Cycling ↑ VO₂ max (aerobic capacity) by 12% in 8 weeks (mitochondrial biogenesis) Jumping Rope ↑ Bone mineral density by 3.2% in 6 months (stimulates osteoblasts) Swimming ↓ Systemic inflammation (CRP levels) by 15% (reduces IL-6 cytokines)

8. WHO Guidelines & Solutions: How Much is Enough? WHO Recommendations: Adults: 150+ mins moderate exercise OR 75 mins vigorous (e.g., running). Muscle-Strengthening: 2x/week (e.g., weights, yoga). Simple Swaps: Take calls while walking. Use stairs instead of elevators. Stand every 30 mins at work.

9. Conclusion The evidence overwhelmingly demonstrates that physical inactivity is a silent yet potent driver of non-communicable diseases. However, the solution is equally clear: incorporating 30 minutes of daily activity—whether through brisk walking, strength training, or simple lifestyle swaps like taking the stairs—can reduce disease risks by up to 40%. These findings underscore that combating inactivity isn’t just an individual responsibility but a societal imperative, requiring both personal commitment and systemic support through workplace policies and urban design. By prioritizing movement today, we invest in a healthier, more productive future.
