Unit I – Active Recreation & Healthy Lifestyle Factors

Formal Definition (Page-6)

Lifestyle = “The way in which an individual lives.”
Components: routines at home/school/work; eating, sleeping, exercise; screen time; social interactions.
Health Link: Patterns may either elevate or reduce health risks (e.g., obesity, diabetes, hypertension).
Teen Focus: Adolescence is a critical window—habits formed now track into adulthood. Nutritional vigilance is essential.

Gradual Modification Strategy (Page-7)

Principle: Small, incremental changes create sustainable habits.
- E.g., cut fatty food portions rather than a total ban.
- Choose to fetch items yourself (NEAT: Non-Exercise Activity Thermogenesis).
- Walk briskly more often; increase step count by $1{,}000$ each week.
Behaviour-Change Theory Connection: Aligns with the Transtheoretical Model (pre-contemplation → action → maintenance) and Self-Efficacy theory (mastery through small wins).

Evaluating Eating Practices (Pages-8 & 9)

Table of Practices — classify as Healthy or Unhealthy and justify:
- Eating fruit daily → Healthy (micronutrients, fibre).
- Eating in moderation → Healthy (portion control prevents obesity).
- Skipping meals regularly → Unhealthy (leads to bingeing, metabolic slowdown).
- Consuming sweets uncontrollably → Unhealthy (spikes insulin, dental caries).
- Substituting water for rice → Context-dependent but usually Unhealthy (may indicate fad diets, nutrient imbalance).
- Eating meat products moderately → Healthy (protein source without excess saturated fat).
- Preferring home-cooked meals over fast food → Healthy (less sodium, trans-fat).
- Leaving out vegetables in sinigang → Unhealthy (losing fibre and vitamins).
- Minimizing deep-fried foods → Healthy (cuts trans-fat, acrylamide).
- Choosing soft drinks as first beverage → Unhealthy (empty calories, phosphoric acid harms bone).

Seven Important Lifestyle Factors (Pages-10 to 16)

Healthy, Balanced Diet
- $3$ main meals + healthy mid-morning & mid-afternoon snacks.
- Prevents overweight and non-communicable diseases (NCDs) like T2DM, CVD.
- Macronutrient distribution ranges: $45\%-65\%$ carbs, $10\%-35\%$ protein, $20\%-35\%$ fat.
Adequate Water Intake
- Human survival: $\approx 3$ weeks w/o food vs. < $(7$ days w/o water).
- Recommendation: $8$ glasses (≈ $(2$ L) pure water daily.
- Note: Juices & sodas ≠ water due to sugar, additives.
Regular Exercise
- Boosts muscle strength, bone density → lowers osteoporosis risk.
- Enhances lung capacity, VO₂ max, and functional fitness.
- Psychological benefits: improves mood (endorphins), sleep, and stress management.
Plenty of Sleep
- Minimum $7$ hours/night for metabolic restoration.
- Processes: cellular repair, memory consolidation, toxin clearance (glymphatic system).
- Chronic sleep debt → raised cortisol, insulin resistance, mood disorders.
No Smoking
- Nicotine & tar implicated in CAD, PUD, GERD, hypertension, delayed wound healing, multiple cancers.
- Reduces life expectancy; second-hand smoke equally harmful.
Reduced Alcohol Consumption
- Safe threshold: ≈ $1$ drink/day.
- Excess → cardiomyopathy, liver cirrhosis, hypertension, stroke, cancers (esp. liver).
- Addiction risk → accidents, violence, suicidality.
Regular Health Check-ups (Physical & Mental)
- Establish open rapport with healthcare providers.
- Early detection = higher cure rates (e.g., Pap smear, fasting lipid profile, PHQ-9 for depression).
- Integrates the Biopsychosocial model of health.

Lifestyle Risk Factors (Page-17)

Food Choice
- High-calorie, nutrient-poor selections ↑ obesity risk.
Physical Activity Level
- Sedentarism lowers energy expenditure, predisposes to metabolic syndrome.
Eating Habits
- Irregular meal timing, emotional eating, late-night snacking contribute to dyslipidemia, GI issues.

Assessment Review (Page-18)

Recall-type Questions:
1. Identify the three lifestyle risk factors (Food Choice, Physical Activity, Eating Habits).
2. List the seven important lifestyle factors (Balanced Diet, Water, Exercise, Sleep, No Smoking, Limited Alcohol, Health Check-ups).
Study Tip: Convert to mnemonic “DEWSNAH” (Diet-Exercise-Water-Sleep-No smoking-Alcohol-Health check-up) for retention.

Assignment Prompt (Page-19)

“List at least $10$ Active Recreational Activities.”
- Examples: brisk walking, cycling, swimming, badminton, basketball, hiking, dance fitness (Zumba), jump rope, frisbee, inline skating.
- Link to course: Reinforces Unit I focus on Active Recreation.

Integrative & Real-World Connections

WHO Global Action Plan: echoes the $\ge 150$ min/week MVPA guideline—aligns with Philippine curriculum codes.
Economic Impact: Healthy lifestyle lowers healthcare costs and absenteeism.
Ethical Angle: Informed choices respect personal autonomy but intersect with public-health policy (e.g., sin-tax on cigarettes, sugary-drink tax).
Philosophical Lens: Aristotelian “Golden Mean”—moderation in diet, drink, and activity.
STEM Link: Application of energy-balance equation $\Delta W = Energy<em>{in} - Energy</em>{out}$ to weight management.

Practical Tips & Hypothetical Scenarios

If a student currently drinks only $2$ glasses of water/day, add $1$ extra glass every two days to reach the $8$ -glass goal in a week.
Replace $30$ min of evening TV with a family walk → achieves MVPA + social bonding.
Weekend community clean-up = service learning, exercise, environmental stewardship.

Summary Cheat-Sheet

Strive for >60 min MVPA daily, $8$ glasses water, $7$ h sleep, balanced plate method (½ veggies+fruits, ¼ protein, ¼ carbs).
Avoid tobacco entirely; limit alcohol to $\le1$ drink/day.
Schedule annual check-ups; monitor BP, fasting glucose, mental-health status.
Small, consistent habit changes compound into lifelong wellness.
