Why do hospice patients sleep with their mouth open?


Editorial team Published on

Hospice patients sleep with their mouths open because profound muscle relaxation and weakness at the end of life cause the jaw and facial muscles to let go.

Key Causes

  • Extreme Muscle Relaxation: As the body weakens and approaches the final stages, the jaw, neck, and facial muscles lose tone and the ability to stay contracted, causing the mouth to naturally drop open.
  • Deep Sleep and Unresponsiveness: Patients spend more time in deep, heavy sleep or fading consciousness, reducing active control over posture and facial expressions.
  • Medication Side Effects: Palliative medications, including pain relievers and anti-anxiety drugs, relax the nervous system and dry out mucous membranes, making breathing through the mouth more likely.
  • Altered Breathing Patterns: Changes in breathing rates, shallow breaths, or congestion force the body to rely on oral airflow for easier oxygen intake.

How Caregivers Can Help

  • Moisturize the Mouth: Use specialized oral swabs, water-soaked foam sticks, or lip balm frequently to keep the lips and tongue from drying out and cracking.
  • Reposition Gently: Adjust the patient's head or turn them slightly onto their side with a pillow to improve comfort and airflow.
  • Consult the Care Team: Speak with your Hospice Foundation of America nurse or local care provider if you notice signs of distress or need specific comfort-care tools.
