Our body creates most of our vitamin D from direct sunlight on our skin. We also get vitamin D from some foods â including eggs, meat and oily fish such as salmon, mackerel and sardines.

However, the UVB rays pose risk of sunburn as well, which is why it's better not to spend more than the recommended time in the sun.
