I know my wife has trouble breathing warm air, specifically rebreathing air, because it causes her asthma to flare (I have no clue why, it just does). I personally don't have a problem with it, but I'm not particularly sure I'd be comfortable sitting in a perfectly lit break room with my head in a sack. This might just be a product of my environment from going to an all boys highschool, but I'd never get to sleep from the perpetual feeling that someone's just going to come up behind me and smack my head on the table. Then again I have less than a handful of naps a year so I don't think this product is really targeted towards me.
