Five signs you may have sleep apnoea

If a person sleeps with an open mouth and tends to breathe through their mouth rather than their nose, this is the simple reason for a dry mouth upon waking. Chronic breathing through the mouth can also lead to a sore throat. Morning dehydration can occur if a person’s body is starved of oxygen leading them to consume more water. Other symptoms of OSA can include night sweats and frequent urination at night which can further increase dehydration.
