Getting outdoors is also important to staying healthy, as sunlight is an important source of vitamin D. Vitamin D helps our bodies to absorb calcium and phosphorus from our diets, which is needed to maintain strong bones and teeth. In childhood our bones are strong and, if they break, they usually repair quickly.
When we get older this process slows down and our joints can become weak and fragile.
We begin to lose bone density from our mid-30s, which is a normal part of ageing. Lifestyle factors such as having a calcium-rich diet and exercising frequently can keep bones healthy and minimise the risk of fractures. Sunlight exposure is also crucial to up levels of vitamin D.
