Depression could be due to deficiencies of vitamin D
When it comes to the deficiencies of two very important vitamins, they could lead to a state of depression. One of these vitamins is vitamin B12 which affects every one out of four people.
Besides, vitamin D is equally important too. In medical studies, it has been found that those with the lowest level of the vitamin D were actually 11 times more susceptible to be depressed compared to the people who have normal levels.
In addition, the 9 September 2010 edition of the Archives of General Psychiatry has published a study which discovered that it is crucial to maintain a proper levels of the vitamin D during early infancy as it could help to prevent a more severe mental disorder which is schizophrenia. Those newborn babies that has a low levels of vitamin D were more prone to develop schizophrenia at their later years in life. This in turn has lead medical researches to suggest that vitamin D supplements could perhaps be required to prevent this dreadful illness.
Some medical researchers also made a population comparison between those that live in cold countries that have dark-skinned compared to those from the urban areas that do not usually get enough regular sunlight. Their conclusion was that by giving vitamin D supplements, the incidence of schizophrenia could be reduced by a whopping 87 percent.
The most effective way to obtain vitamin D is by exposing to regular sunshine and not popping in pills or tablets. Bear in mind that SAD (Seasonal Affective Disorder) is a form of depression which is related to the deficiencies of sunlight. As such, it makes perfect sense that the best method to get vitamin D is through the sun exposure. If you cannot have access to the sun regularly, then a safe tanning bed is the alternative.
It is also very likely that natural sunlight has independent benefit for mental health too besides from the direct vitamin D benefit. As such, it is not surprisingly why SAD is so persistent during the winter months and why depression is such widespread during the winter in Pacific Northwest.
So in conclusion, sunlight deficiency is a significant risk factor when it comes to depression.
