Vitamin D deficiency
I've probably had vitamin D deficiency all my life. I avoided the sun for years, because as a child I was afraid of sunburn, later I was afraid of skin cancer. A connection with my years of knee pain when hiking and cycling, I consider possible. Also, I know many phases of listlessness and depression from my life. Fragile fingernails have been around for ages. Also, I have experienced phases in which I constantly had colds. My blood circulation was weak for years. In 2014 my vitamin D level was measured for the first time: 15 ng/ml! |
Vitamin D deficiency obviously promotes autoimmune reactions. Autoimmune diseases are the rarest in the world around the equator, most often in countries far from the equator. This means that a connection with the sunlight is likely. In turn, sunlight is crucial for vitamin D formation through the skin. It has also been known for many years that vitamin D deficiency in children is associated with the risk of developing type 1 diabetes. For example, in this study. Conversely, it was found that the number of children with type 1 diabetes decreased in Finland after the nationwide (re)introduction of vitamin D substitution. |
