✔ If parents are shorter, the child may follow a similar pattern.

2. Nutrition (Balanced Diet Is Essential!)

✔ Calcium & Vitamin D support strong bones.

✔ Protein is essential for muscle and height growth.

✔ Zinc & Iron prevent growth delays.

3. Physical Activity

✔ Basketball, swimming, and stretching improve posture and spinal health.

✔ Regular exercise stimulates growth hormones naturally.

4. Sleep & Hormones

✔ The body releases growth hormones during deep sleep.

✔ Teens need at least 9–11 hours of sleep per night for optimal growth.

🔹 BMI = Weight (kg) ÷ Height (m²)

✔ Normal BMI range:18.5 – 25

✔ Below 18.5:Underweight

✔ Above 25:Overweight
