Breathe with the Mouth Closed
Generally, breathing with an open mouth dries out the airways quickly. However, some individuals with respiratory illnesses like colds may breathe with the mouth open. Usually, heavy breathing exercises or jogging activities are everyday events that cause individuals to breathe with the mouth open. Making a conscious effort to breathe with a closed mouth frequently will lower the risk of a dry mouth.
Dry mouth causes a significant level of discomfort and may result in severe mouth odor. In most cases, a dry mouth may only require hydration. However, it’s crucial to see the doctor if it is suspected that the dry mouth is due to medications. Individuals with conditions like anxiety disorder, type 2 diabetes, or kidney disease should also consult the doctor.
