In winter time it’s harder because one, you’re wearing more layers so you have less skin exposed to sunlight, and two, because most sunlight is heavier filtered and overcast during the winter and spring seasons. This is why people who live in northern climates should be dosing zinc and vitamin d for realistically over half the year. This is also extremely important if you have darker skin because your body does not absorb sunlight as easily as a pale complexion does. Another important one that people miss is vitamin b12 during the winter time.
