those who have answered with locked knees and improper breathing are right.
When we lock our knees, we cut down the circulation to our legs and lower body, where most of the strength of singing ought to come from. Without that sort of body balance, it's no wonder the brain does a quick shut-down-and-restart maneuver like fainting.
Locking your knees also throws your whole body out of alignment, so , even if you are thinking you are breathing properly, it's not effective enough.
Yes, adrenaline and endorphins are produced while singing ( part of what makes singing so much fun)but neither of these two sorts of natural body chemicals will cause the faints.
it helps to remind yourself to be springy at the knees, and occasionally bend or flex one or the other knee. Ideally when you are not singing, and in such an unobtrusive manner that no one else will ever notice it.
for those who stand in the back rows, no big problem.. For you front row people, just go slow and steady!

all SHOWWWWWWWWWWWWWWW

Its just too loud for them

It's hot in those blig blue robes.

It could be nerves, the stage lights or them not breathing correctly and hyperventalating. Usually it's the latter.

the only answer i can offer is possible overheating from either nerves or lighting and possible lack of oxygen from all the singing... i was in chorus in high school and that's how i felt when i had to be in the concerts

Well the hypachrondria is interchanging with the nucleus forming a sprung motion in the sexual organ causing spontaneous combustion.

Some people improperly breath, so they don't have enough air going in, and faint.

Some lock their bodies, and just fall over, because you have to look presentable.

Also, I'm sure nerves and the like contribute.

For some people singing is just like exercise. The exertion involved can sometimes drain someone if they don't eat before a performance. It's just common sense. If your going to exercise a lot, get a tattoo, or even dental work or a tooth pulled, you're required to eat before hand. It has something to do with adrenaline and output of endorphins. If one doesn't eat, they kind of overdose on the endorphins. No harms done as long as they don't hit their head or somethng when they faint.

Sometimes they faint from heat, If they are on risers they are closest to the lights which are very bright. Also they may have choir robes on with their street clothes under those. Add in some anxiety, performance jitters and possibly not having eaten much the day of the performance. As the above poster said, they lock their knees. Any or all of these things could be responsible.

Because they're too stupid to breathe and sing at the same time.

i myself take on vocal duties in my band, Black Ambulance, and on a couple of occasions i've taken too deep of a breath before letting out a scream/growl and found myself stumbling reaching for the floor. in my case, breathing properly is a major factor. in other cases, maybe nerves, maybe too many shots for courage before the show. join a choir, or front a band, then maybe you can come up with your own hypothesis.

I suppose it's the leak of air, and a lot of standing in feet, the blood is not getting to all the parts of the body. But it must be the air. I am in a choire and noone have ever fainted:))

There are several reasons a singer might faint during a performance. I was in a concert once where several people, including myself, fainted during the final song. It was a surprise for me because I'd never fainted before. The concert was really long and there were a lot of hot lights shining on us. I made the mistake of wearing heals which caused my legs to ache after standing in the same place for a long time. I also ate a late breakfast so I didn't have any lunch. Since it was a 2:00 concert I didn't have enough nutrition to sustain myself. The same was true with water.

In my experience I have found that it is usually a combination of things that cause a person to faint during a concert. More often than not the temperature on the stage, lack of water, and the length of the concert are the major factors.
