Sleep, Nutrition, and Vitamin D: The Hidden Keys to Healthy Growth

Written by Dr. Kelli Davis | Oct 24, 2025

Building Everyday Habits That Support Height and Bone Health

 

Small Daily Habits Create Big Growth

Growth doesn’t happen in the doctor’s office — it happens at home, one meal, one night’s sleep, and one day of movement at a time.

At Life Pediatric Endocrinology, we see the incredible impact of everyday habits. Children who sleep deeply, eat nutritiously, and maintain healthy vitamin D levels not only grow taller, but also stronger, happier, and more resilient.

Why Sleep Matters Most

Growth hormone surges during deep sleep. Children who regularly sleep 9–11 hours per night experience better height velocity and improved metabolism.

To support this:

  • Keep a consistent bedtime

  • Avoid screens one hour before bed

  • Create a dark, cool sleep environment

  • Encourage physical activity during the day

Nutrition: Fuel for Growth

Nutrition is the cornerstone of healthy height. Balanced intake of protein, calcium, iron, and vitamins A, D, and B12 ensures bones and muscles have the raw materials they need.

At LIFE, we recommend:

  • Breakfast: Protein and whole grains (e.g., eggs, oatmeal, yogurt)

  • Lunch/Dinner: Lean proteins, vegetables, and complex carbs

  • Snacks: Cheese sticks, fruit with nut butter, protein smoothies

Family meals and exposure to varied foods encourage healthy relationships with eating — a habit that supports both physical and emotional growth.

Vitamin D: The Sunshine Nutrient

Vitamin D enables calcium absorption and supports bone formation. Many children today are deficient due to indoor lifestyles and sunscreen use.

Encourage:

  • Safe sun exposure 10–15 minutes daily

  • Fortified foods (milk, yogurt, orange juice)

  • Supplements if recommended by your provider

Optimal vitamin D levels support bone density, muscle function, and immune balance — all essential for healthy growth.

Our team can suggest appetite and nutrition strategies that ensure balance without battles.

3. How do I know if my child needs vitamin D supplements?
A simple blood test can guide dosing based on their individual needs.
