We do not want to finish the summer
without you to had our little contribution and so in this post the Sun will be
the protagonist, whose function is not only to tan us but, among other things,
help us to synthesize a small key molecule in our life: vitamin D. We are going
to talk very briefly the main features of the sunlight, how it affect us and
what precautions we have to take against it to, finally, explain how our star
helps us producing vitamin D and why it is so important to do so.
We hope you enjoy and that it entertain you during a hot summer minutes.
