Will I get vitamin D deficiency if I use sunscreen in winter?admin
Vitamin D is actually not a real vitamin at all. It cannot be supplied to the body exclusively from the outside, but is mostly (about 80 to 90 percent) produced by the body itself. Such vitamin D synthesis takes place in the skin and is triggered by exposure to sunlight. Theoretically, deficiency symptoms can occur in the dark winter months.
Fortunately, this rarely happens in practice. On the one hand, this is due to the fact that even a short stay in the sun is enough to stimulate the production of the “sun hormone”. On the other hand, most people in our latitudes don’t wear enough sunscreen anyway. For short stays in the sun, many do without it or apply sunscreen too thinly and not completely. Also, the sun’s rays that cause sunburn and those that stimulate vitamin D production aren’t quite in the same range.
Consequences of vitamin D deficiency
Vitamin D affects bone health, the immune system and fertility. A vitamin D deficiency can therefore lead to a weakened immune system, listlessness, fatigue , hair loss and premature aging of the skin.
However, there are many other reasons for these complaints. You can check whether you actually have a vitamin D deficiency with a simple blood test at the doctor’s.

Tips against vitamin D deficiency in winter
+ Soak up the sun: Since the angle of incidence of the winter sun is lower than in summer, only small amounts of UVB radiation, which is relevant for vitamin D, reach the earth. Nevertheless, you should enjoy the sun as often as possible, even in winter. For example, you can stand by the open window in between and let some radiation shine on your face, neck and forearms.
+ Nutrition: The less sun we can soak up in winter, the more we are dependent on the vitamin D supply through nutrition. Above all, oily sea fish (salmon, herring, eel) has a supporting effect.
+ Dietary supplements : Those who do not like to eat fish every day can (after consulting a doctor!) also use special dietary supplements to boost their vitamin D level. The effect can never be compared with the effect of the summer sun; nevertheless, such support can certainly be beneficial.
+ Excursions: Flying out in the sun for a few days not only raises the vitamin D level, but above all also the mood. But you can also fill up on relaxation and vitamin D in this country – without having to travel many kilometers. In high mountainous areas in particular, the solar radiation is significantly more intense than in the lowlands. Here you should not do without sunscreen because of the high risk of sunburn !
+ False conclusion daylight lamp: Such lamps imitate natural light and actually have a short-term brightening effect on the mood and perceived vitality. In this respect, daylight lamps are beneficial against the winter blues; Unfortunately, they cannot guarantee a real vitamin D supply. These devices emit too little UVB radiation for this.
Bottom Line : Not wearing sunscreen out of concern about vitamin D deficiency is not a good idea. After all, even small amounts of sunlight can be enough to get the vitamin D balance going again. That’s why it’s also true in winter: regular sun protection is mandatory and no exception!
