We evolved spending most of our time outdoors for most of our history, only after the industrial revolution and now the information revolution did we gradually work more and more in doors. Vitamin D deficiency is at almost epidemic proportions. Short of switching careers to a road crew, Vitamin D deficiency should be very high on the list of suspects any time the symptoms of any form of depression are observed.
Vitamin D deficiency is a symptom. What is missing is not vitamin D but sunlight. Giving superficial vitamin D is doctoring on ONE symptom not on the cause of multiple deficiencies.
A correct therapy would be for example:
* Do short ways (<2km) per foot.
* Do medium ways (< 20 km) per bicycle
* Do longer ways as a combination of public transport and foot.
* Do programming in parks, outside cafe terrace or in the garden
* Get a dog and go with him every day
* Start jogging
etc.
There are lot of possibilities to change your modern life to a for the human race suitable lifestyle.
Swallowing a pill instead of getting sun, fresh air and exercise is one way to burn out.
It takes effort to change your live instead of swallowing a pill and costs more time in the short run, but it extends lifetime and saves illness time. Therefore it saves time in the long run and makes live happier.
