🦴 BONE DENSITY SCIENCE
PAGE 1 OF 5 — LIVING BONES
NOT DEAD ROCK
YOUR BONES ARE ALIVE
Bones might look hard and still, but they are living tissue. Inside them, special cells are constantly breaking down old bone and building new bone. This remodelling keeps your skeleton strong and repairs tiny cracks from everyday life. When you are young, your body builds bone faster than it loses it. That is why childhood and the teen years are a golden time to grow a sturdy frame.
🔄 REMODEL
Bone remodelling means old bone tissue is replaced by new bone tissue all through your life.

USE IT
BONES RESPOND TO LOAD
Bones grow stronger when they feel safe stress. Scientists call this Wolff's law: bone adapts to the loads placed on it. Weight-bearing and impact exercises send signals that say build denser bone here. Jumping, hopping, running, brisk walking, and dancing all count. Swimming is great for fitness, but your bones need ground impact to pack in minerals and become harder to break.
💥 IMPACT
Short bursts of impact, like jumping or jogging, stimulate bone-building cells more than sitting still.

BUILDING BLOCKS
MINERALS MAKE BONE HARD
Calcium is the main mineral packed into bone, giving it hardness. Your body also needs vitamin D to absorb calcium from food. Dairy, fortified plant milks, leafy greens, and small fish with soft bones are good sources. Without enough calcium, bones can become thin and brittle over time. Exercise tells bones where to build. Nutrition gives them the bricks to build with.
🥛 CALCIUM
Most of the calcium in your body lives in your bones and teeth, acting like a mineral bank.

PEAK BONE
BUILD NOW FOR LATER
You reach peak bone mass in your late teens or early twenties. The denser your bones are then, the more reserve you have for adulthood. Too much sitting and too little activity can leave bones weaker. Sports, playground games, and active play deposit strength into your bone bank. Parents and coaches can help by encouraging varied movement and calcium-rich meals.
🏦 PEAK
Higher peak bone mass in youth means stronger bones for decades ahead.

DAILY HABITS
MOVE AND FEED YOUR BONES
Strong bones are built by living tissue, impact exercise, and calcium-rich food. Jump, run, walk, and play so your skeleton gets the signals it needs. Eat well and get daylight for vitamin D. Your bones are always listening to how you move. Give them reason to grow dense and tough.

REMEMBER
💪 KEY FACTS
Bones are living tissue that rebuild constantly. Impact exercise and calcium make them denser and harder to break. Build strong habits while you are young.
