Does your day include getting up early in the morning, traveling to the office, all day there, and going home in the evening? Or staying home office all day? How much time do you spend in the sun? Here’s a fact, vitamin D does not accumulate if you stand behind windows. It is produced by the body only when UVB rays touch the skin. Glass windows block this wavelength, which means that the skin does not produce vitamin D through glass, even if you sit in the sun next to a window. If we don’t stay outside long enough, we can get the vitamin deficiency.
Can we get enough Vitamin D from the sun?
To get enough vitamin D, the recommendations are to spend at least 15-30 minutes in the sun every day from 10 am to 3 pm, and it is important that almost the whole body is exposed to the rays or at least the face, whole legs and arms. It’s a little difficult to do that all year round, isn’t it?
Do you walk outside often? And do you use sunscreen? SPF 8 almost completely eliminates UVB rays from reaching the skin, thus preventing the production of vitamin D. The problem is that most of us do not spend enough time in the sun. In reality, we often hide from the sun by standing under a hat or in the shade and always use sunscreen.
It is believed that the main reasons why vitamin D3 levels have declined over the past few decades are due to a greater use of sunscreen and spending more time indoors in front of computers. In addition, people living in big cities suffer from vitamin deficiency, not only because of the daily morning fog that absorbs UV rays, but also because of high-rise buildings.
Why do we need to take Vitamin D as a supplement?
I am sure that for many people the green lifestyle excludes taking vitamins in pills. But sometimes, in order to maintain the balance between the well-being of our body and our urban existence, it is good to break the rules we impose on ourselves. In this case, it is because of this solar vitamin.
If you can afford only one dietary supplement, let it not be a multivitamin, but a Vitamin D. Vitamin D plays a key role in our overall health, and its deficiency worldwide continues to grow. According to data from various studies in different parts of the world, vitamin D deficiency varies from 50 to over 90% of the world’s population.

In fact, vitamin D helps to modulate the immune system and without it, it has no chance to deal with the intruders.
Vitamin D3 may be one of the keys to treating ever-increasing autoimmune diseases. There is research that Vitamin D seems to affect the way we age. There are strong suggestions that low levels of vitamin D are associated with fat accumulation. Almost all overweight people suffer from vitamin deficiency.
