in some cases, beneficial.... kind of like "afternoon delights"!!!!
I'm not one to really nap. I dunno, guess I'm too busy to have em. If I ever do nap, is usually when I'm sick.

I personally love naps. They are usually more beneficial, but sometimes it can screw my sleep routine up.
I used to do this at weekends around lunch time but invariably I woke up feeling terribly groggy and worse for the experience so I gave it up years ago.
I work either afternoon/evening shifts (late 1st transitioning into 2nd shift) or 3rd (graveyard) shift, so sleeping during the late morning into the early afternoon really isn't an option--it's a requirement. I've never experienced any detrimental effects from sleeping during the day--much worse to not sleep at all, which happens on occasion.

It has never even occurred to me to nap, unless I am sick, or jet-lagged. My dad napped every day after lunch, at work, and, when he had long commutes, used to park his car at a gas station and nap on the drive home. My last boyfriend was a big fan of naps. I can't imagine they would be detrimental, unless you chose to do them on a subway train, or a runway, or something.
Not sure .... never had opportunities to do that on a normal type day.... but I can see where a "power nap", 2o min or more might be good!
They can be both it depends on how you feel.
If I'm beyond tired a nap usually makes me feel worse. If I didn't get enough sleep the night before and I start feeling sluggish then a half hour nap is wonderful. That being said I'm a shift worker and I'm sort of use to sleeping when need be.
I am able to power nap after lunch and I definitely find it improves my concentration later in the day.
detrimental: messes up the Circadian rhythm, harder to get a deep sleep and I don't feel any better
