If your mouth feels dry at night, here are 8 reasons why

Over 400+ medications list dry mouth as a side effect, including:

Antihistamines (e.g., Benadryl)

Decongestants

Antidepressants (SSRIs, tricyclics)

Blood pressure drugs (diuretics, beta-blockers)

Muscle relaxants

 Fix:

Ask your doctor about alternatives

Sip water before bed

Use a prescription saliva substitute if needed 3. Sleep Apnea

Why: People with sleep apnea often gasp or breathe through their mouth all night, leading to severe dryness—plus snoring, daytime fatigue, and morning headaches.

 Fix:

If you snore loudly or wake up gasping, talk to your doctor about a sleep study

CPAP therapy often resolves dry mouth by restoring nasal breathing

 4. Dehydration

Not drinking
