What your mouth needs saliva for

Saliva (spit) is made by glands in your mouth. It keeps your mouth wet and comfortable [1]. It helps you chew and swallow food [1]. It also rinses away tiny food bits that stick to your teeth [1]. Saliva has minerals that help protect teeth, too [1].

What a dry mouth means

Doctors call a dry mouth xerostomia (the medical word for too little saliva). It means your mouth does not make enough saliva to stay moist [1]. Nearly everyone feels this now and then, such as when nervous or stressed [1]. A dry mouth that stays for long is more bothersome. It can make eating and talking harder [1].

Common reasons you wake up with a dry mouth

Breathing through your mouth is one known cause [1]. Some people do this in their sleep without knowing it. Alcohol, tobacco and other substances can also dry the mouth [1]. Some medicines list dry mouth as a side effect, including certain ones for blood pressure, low mood and bladder control [1]. Do not stop any medicine on your own. Ask your doctor or pharmacist first.

When to see a doctor or dentist

Some health conditions can lead to a dry mouth. Examples are Sjogren's syndrome (an immune condition), diabetes and problems with the salivary glands [1]. Some cancer treatments can also change saliva [1]. If your mouth is dry most nights, book a visit with your doctor. A dry mouth can raise the risk of tooth decay and mouth infections, so a dentist check is wise too [1].

Gentle breath habits before bed

Yoga cannot treat a dry mouth, but calm breathing may help you relax and notice how you breathe. Try Alternate Nostril Breathing (Nadi Shodhana), a slow breath practice that keeps your attention on the nose. You can also try Bee Breath (Bhramari), a soft humming breath. Practise gently and stop if you feel dizzy. Since mouth breathing is a known cause, learning to notice it by day is a kind first step [1].

Balance in your evening routine

The Bhagavad Gita (6.16-17) teaches balance in eating, sleeping, effort and rest. You can bring this idea to your evenings. Keep alcohol and tobacco light or avoid them, because both can dry the mouth [1]. Keep a calm, regular bedtime. Small, steady changes often work better than big, sudden ones.

Try it: simple steps

  1. Notice if you breathe through your mouth during the day.
  2. Cut back on alcohol and tobacco, especially in the evening [1].
  3. Ask your pharmacist if any of your medicines can dry the mouth [1].
  4. Practise Bee Breath (Bhramari) for a few calm minutes before bed.
  5. Keep a regular, quiet bedtime routine.
  6. Tell your doctor if the dryness happens most nights.
  7. Visit your dentist often to look after your teeth [1].
