When someone sleeps on his/her side,what effect will this have on the person's body?
Also when we sleep on our stomach,does this effect our body while we sleep,does it restrict any of our organ functions etc?

Another thing I wanted to ask was-
When we drink water or other fluids, if we gulp it down at once or if we drink slowly say in three gulps, does this make a difference?

I know these two are not related but I ask these for the same reason...

Thanks in advance.:)
