Vitamin D deficiency is a contributory factor to develop this disease entity ,
In the last few decades ,in India,children have been observed to be busy in indoor activities and more in screen activities.
On the one hand,this indoor confinement leads to less sun exposure and on the other hand the contents of screen may be depressive
In winter season ,naturally there is less time when there is sunlight, in which children can be exposed while playing.
Adequate vitamin D synthesis in the body occurs when skin is exposed to sunlight.
It has been observed that in winter season ,the level of serotonin is less in the body and melatonin balance is also disturbed.
These lead to increased symptoms of depression.
Sun exposure between 10 am to 3 pm is most effective for vitamin D synthesis from ultraviolet B light
