Breathing through your mouth can reduce one's life expectancy by a decade.

Lying in bed last night I became aware of my breathing.
40 plus years ago, after one of the regular bashings I received my nose was broken.
I remember the doctor talking about requiring a Septoplasty operation, a procedure to straighten the septum (the cartilage and bone inside your nose that separates your nostrils)
I do know that I never had that operation for what ever reason.
Since having my nose broken I have always breathed through my mouth as using the nose requires me to actively think about breathing. For me breathing through my nose is not natural and requires far more effort than mouth breathing.

Mouth Breathing negative aspects;
Results in less pressure in the airway, leading to less efficient oxygen/CO2 exchange
Increases snoring and sleep apnea
Lowers heart rate variability
Reduces sleep quality
Reduces the release of vasopressin, a hormone which eventually impacts kidney function
and the body's water balance
Increases the likelihood of periodontal disease (tooth decay) as it significantly changes the mouth's pH
Bypasses a key function of nasal tissue, namely to regulate blood flow ad brain function

The above issues when taken as a whole can reduce life expectancy by up to a decade.
Oh great, as if there is not enough to worry about getting through life.
Now I am being told if I want to live longer I need to Shut My Mouth
