Sleeping Problems Linked to COPD
It is very common for people with chronic obstructive pulmonary disease (COPD) to have trouble getting a good night’s sleep. In fact, around half of people with COPD have sleep disruptions and trouble sleeping well. This is a problem because getting enough sleep is very important for all of the body’s functions to work well.
What sleep issues do people with COPD have?
Common sleeping problems in people who have COPD include1,2:
- Trouble going to sleep
- Trouble staying asleep
- Sleepiness during the daytime
- Waking up due to headaches
- Waking up due to shortness of breath
- Brief periods of not breathing during sleep
What causes these sleep issues?
There are several ways that having COPD is linked to sleeping problems2:
- Sleep apnea
- COPD symptoms like coughing, wheezing, and breathlessness
- Low levels of oxygen during sleep
- Medications used to treat COPD symptoms
- Anxiety and depression
People with COPD who have sleeping problems should let their healthcare providers know. A sleep evaluation can help figure out exactly what is causing the sleep disruption and the best way to treat it.
Sleep apnea and COPD
Sleep apnea is a condition in which a person stops breathing and then starts again after a short time. This can happen many times during the night. Many people with sleep apnea snore very loudly as well. They often feel tired during the day, because their quality of sleep at night is poor.3
Sleep apnea is not caused by COPD, but having COPD can make the symptoms of sleep apnea worse. People with sleep apnea often sleep better using a special mask that prevents breathing from stopping and starting during the night.
What role do COPD symptoms play in sleep?
These symptoms of COPD can wake a person up several times during the night2:
- Shortness of breath
Many people find it helpful to sleep with their heads elevated on 2 to 3 pillows. This allows the lungs to expand more fully. Medications can also be used to treat those symptoms by improving breathing function. When patients breathe better during the night, they sleep better because they do not keep waking up.
Low oxygen levels and sleep
The way people breathe naturally changes during sleep. For people with COPD, this change in breathing can cause a low level of oxygen in the blood at different times during the night. This can make them have a poor quality of sleep, and feel tired during the day.4
The lack of oxygen in the blood can cause many other problems, some of which are serious. The patient’s healthcare provider can carry out tests to find out if low levels of oxygen in the blood are causing the sleeping problems. If so, the patient might need to have oxygen therapy during the night.4
How COPD medications might affect sleep
Bronchodilators are medicines used to treat COPD symptoms. However, they can make it difficult to fall asleep. Patients should let their healthcare providers know if they are having problems going to sleep while taking any kind of bronchodilator.2
People with COPD are usually not able to take sleeping pills. This is because sleeping pills can slow down nighttime breathing to a harmful extent for people with COPD.
Sleep issues from anxiety and/or depression
Depression and anxiety can both cause insomnia, which is trouble going to sleep and staying asleep. Nightmares are also common in people with anxiety. Treatment for anxiety or depression can help reduce these sleeping problems.5
