Vitamin D is obtained from natural light, cold, rain, heat
Vitamin D is actually not a vitamin but a hormone (because we get vitamin D through food and nutritional supplements, but also through sunlight). This micronutrient is better known as a key factor in building bones. If there is a sufficient amount of vitamin D in the body, then it can more easily bind to calcium and thus prevent the occurrence of osteoporosis. Vitamin D is important for the human immune system because it destroys disease-causing cells that have entered the body. Lack of vitamins weakens the body. About 80% of people are deficient in vitamin D during the winter because sunlight is weak and food intake is insufficient.
Every person should take advantage of even weak daylight and stay outdoors. Staying and being exposed outdoors even during cold, rain, heat, snow and dew contributes to the intake of vitamin D and also strengthens the organism – according to the doctor of Traditional European Medicine Sebastian Kneipp. Regular walks also help.
- Self-production of vitamin D – it is best to start self-production of the vitamin by exposing the hands, face and neck to the sun according to the season for 5 to 30 minutes a day. Thus, from spring to autumn, sufficient reserves of vitamin D can be created, which can be kept in the body for months.
- Nutrition – you should take advantage of the opportunity, even though you can get only a small part of this vitamin with food. Good sources are fatty fish (herring, salmon, mackerel), egg yolks, avocados, mushrooms and beef liver.
- Supplements – doctors and pharmacists recommend taking smaller weekly doses of vitamin D. The assumption is that large doses cannot be absorbed in the body at all. A doctor’s consultation regarding dosage is required to avoid overdose.
- A low level of vitamin D can cause a sub-depressive state known as “Autumn Blues” (or “Winter Blues”), the final outcome of which can be winter depression. Mental stability is an important element in maintaining the normal function of the organism.
- It is desirable to measure the value of vitamin D in the body. Deficiency is easily determined by blood analysis. Limit values are around 50 nmol/l (or 20 ng/ml) in blood. A value below 25 nmol/L (or 10 ng/ml) suggests a critical lack of vitamin D in the body.
