text: why do people salivate while sleeping? is there any remedy to stop it? i know people aged 35 doing it !? i know it about guys but not sure about gals that if they salivate during sleep or not. there are many theories that it may be caused due to improper sleeping or some disorder. but i haven't found one single medication, therapy, or assistance in getting rid of the habit ! i am a grown man drolling like a baby !! it is normal for someone who sleeps with their mouth open to drool.  we all do it.  you should try sleeping in a different position.  it doesn't hurt anything and does not indicate some sort of sleep disorder.  it is not a habit that can be overcome, it is your body's natural function to keep the mouth moist.  if you can find a way to keep your mouth closed while sleepng, you won't drool.
