The winter has officially made its mark. It is cold, windy and rainy. The darkness sets in early too. This means you do not see the sun for a while and this can have a big impact on your mood and energy levels. You do not only receive vitamin D from sunlight. It also affects hunderds of other processes in your body and skin that need the sun to function the right way. These processes work less efficient now. Keep your head up and when you can get a bit of sun, always take it.
