If you get cold, you can get a fever. When your body is hot, you lose water and have a dry mouth at night. You may feel a burning sensation in your mouth. You can relieve these symptoms by cooling down your body or taking medication.

8.Hyperthyroidism

Hyperthyroidism causes the body’s metabolism to speed up and the sympathetic nerves become more excited, which makes the dryness of the mouth more obvious.

One of these reasons may be why you feel dry mouth at night. If it is related to poor dietary habits, you’ll need to adjust and maintain oral hygiene. If it is caused by a disease, then consult your doctor for an examination and treatment as soon as possible.
