OUTSIDE
Almost 60% of all Dutch people have a Vitamin D deficiency in the winter. This isn’t surprising when you think of going outside in the Netherlands’ cold months. Walking around in the pouring rain and icy chill? No thanks, we’d rather stay inside. Still, being outside is important. Children play outside less and less these days — but how are they supposed to enjoy all the outdoors has to offer? Or avoid a Vitamin D deficiency? Slide your seat closer to the window or step outside your door. Today you’ll find life outside.
