Part of that might be the harsh nature of fluorescent lighting used in a lot of offices. Natural light is broad spectrum, but typical fluorescent lighting is a few sharp peaks. Combined with the 120 Hz flicker common in many I find them pretty unpleasant, especially for long periods of time. I find I don't mind higher CRI and higher frequency lighting nearly as much. You can get that in fluorescent lights and they're not as bad as they used to be, but the really good ones are expensive.
