1. It might appear that in a country like India this question is less relevant. But in fact it is not so. When you observe people living in countries where sunlight is abundant, they mostly try to avoid sunlight wherever possible - due to a number of reasons of course, one simply may being not to get any more tanned than necessary.

2. In developing countries at least the way while going to work used to be somewhat outdoors, but since this is changing and more and more people are working in offices, going to work by car and all rooms being fully equipped with AC, we cannot ensure that receive their daily optimum dosage of sunlight.

3. It is reported in various news and media channels for example in India, that people are getting more and more depression, especially in cities. This was unheard of in the past. Reason for this need to be studied more and certainly stress plays a major role, but there are chances that subtle things like less exposure to sunlight (which was abundant and natural so far) are also reasons that support such mental diseases.

In conclusion I would suggest that all offices, hospitals and schools around the world - being in sunlight rich or sunlight poorer countries - should be equipped with the best possible lighting of which full spectrum light still is the most natural choice.
