Invisible Lights Benefits

So some healthcare professionals are concern that all the new bulbs only deliver visible light, minimise invisible lights, which is seen as wastage, that we are missing out on the health benefits of these invisible lights, namely infrared.  And how they may affect sleep because of their longer wavelengths.

I think it is a little bit nonsense.  He did mention to go out and get some Sun is the best way to obtain the therapeutic benefits of these invisible lights.  Do that.
