We all know the feeling of waking up in the middle of the night with extremely dry mouth and thirst and needing to down a pint of water.
Mouth breathing plays a huge part in this, during the day and night.
Your body is about 60 percent water. Lose even 1.5 percent of that H2O — the tipping point for mild dehydration — and your mood, energy levels and cognitive function all drop, according to research from the University of Connecticut.
It can cause mild headaches, dull skin, dark circles, general tiredness.
Start somewhere by breathing through your nose.
