Old people and sleep

Not only old people but young people do sleep with mouth open due to various reasons like tiredness etc.

Not only old, many young people sleep with open mouth.It may be due to bad respiration system.

It is not their habit to sleep by open mouth but it opened accidentally.

I don't think that only old people sleep with their mouth open.This is due to problems in respiratory system.

if the weight of the body exceed their limit then this condition arise today young or old people both open mouth while sleeping.

Mostly we find old people sleep open mouth but even some younger people also sleep with open mouth. This is due to problem in breathing. as they couldn't have proper breath from nose at night time so they take breath from mouth also

I have seen many people not only old people.. It`s mainly because of nasal congestion...

It much be due to respiration problem or uneven pillow height which may occur to young people also.

ya right respiration problem is the main reason for open mouth sleeping.

today majority of people sleep by opening his mouth due to the over weight of the body or tiredness.

We generally sleep with open mouth when the oxygen requirement of the body is more and the nose is not sufficient to supply the required amount of oxygen. This is more found among the aged because they seem to be very tired and and their lungs needs more oxygen hence it happens automatically....!

Why do old people sleep with open mouth ?

All people who have some obstacles in nose will sleep with open mouth.
