Kids are full of energy, and running and jumping around outside is not only fun, but also helps strengthen their bones. Just like muscles, bones grow stronger and harder when they are exercised. Known as ‘weight bearing exercise’, this includes any exercise where your feet and legs carry your weight.
The third ingredient that is essential for building healthy, strong bones is vitamin D. Kids absorb vitamin D from safe sun exposure.
During summer in the southern parts of Australia, and all year round in the north, most of us need a few minutes a day of sun exposure to an area of skin equivalent to your face, arms and hands. And, in winter in the southern parts of Australia, most of us need about two to three hours per week to help with our vitamin D levels.
