Orthopnea: shortness of breath when lying down, which can be a sign of an underlying health condition
Experiencing shortness of breath when lying down to sleep can be a frightening experience and may indicate a serious underlying health condition. This condition is called orthopnea and is distinct from paroxysmal nocturnal dyspnea (PND), which occurs when shortness of breath wakes you up at night. Orthopnea can occur when awake or asleep, and people with this condition may need to prop themselves up with several pillows or even sleep sitting up to aid breathing.
Orthopnea is almost always a sign of an underlying medical condition affecting the heart or lungs. One such condition is congenital heart disease, which is a collective term for a range of birth defects that affect the heart. Other potential causes include high blood pressure, also known as hypertension, which is characterised by consistently high blood pressure readings of 140/90 or higher.
If you are experiencing shortness of breath while lying down, it is important to consult a healthcare professional. They will be able to assess your symptoms and medical history and recommend appropriate testing to determine the underlying cause. One such test is a polysomnogram, which involves wearing sensors overnight to monitor your heart rate, breathing, blood oxygen levels, and brain waves.
In the meantime, there are some potential causes and treatments for shortness of breath while sleeping that you may want to consider. Sleep apnea is a common disorder that affects breathing while asleep, causing unusual breathing patterns and preventing restful sleep. It can be treated with continuous positive airway pressure (CPAP) therapy, which uses a mask to blow air into your airway while you sleep, or with an oral device to hold your jaw in the correct position.

Sleep apnea: a common cause of orthopnea, involving narrowed airways and decreased oxygen levels during sleep
Sleep apnea is a common sleep disorder that affects your breathing while you sleep. It involves brief pauses in breathing that can last 20 to 30 seconds, and these can recur hundreds of times a night. This disrupts the sleep cycle and prevents restful sleep, impacting your physical and mental health. Sleep apnea can be caused by either a blockage of the airway (obstructive sleep apnea) or the brain failing to control breathing (central sleep apnea).
Obstructive sleep apnea (OSA) occurs when the muscles in the throat relax during sleep, causing the surrounding tissue to press on and block the windpipe. This is more likely to occur if someone has a narrow throat or a large tongue. Other risk factors include obesity, enlarged tonsils or adenoids, and a thick neck. OSA can cause loud snoring due to the air squeezing through the narrowed airway.
Central sleep apnea (CSA) is a different disorder where breathing stops because the brain temporarily stops sending signals to the muscles that regulate breathing. CSA can be caused by anything that affects the brain's control of breathing and chest muscles, including certain medications.
Mixed or complex sleep apnea is a combination of OSA and CSA. Sleep apnea can cause serious complications, including excessive daytime sleepiness, arrhythmias, high blood pressure, heart disease, stroke, diabetes, and headache syndromes. Treatment options include lifestyle changes, such as weight loss, avoiding alcohol, and sleeping on your side, as well as the use of continuous positive airway pressure (CPAP) devices to keep the airway open during sleep.

Paroxysmal nocturnal dyspnea (PND): a sudden awakening during the night, struggling to breathe
Paroxysmal nocturnal dyspnea (PND) is a sudden awakening during the night, struggling to breathe. It is a form of shortness of breath that occurs during sleep, typically an hour or two after falling asleep. This condition is characterised by episodes of breathlessness that can be scary and alarming, leaving individuals gasping for air. Sitting up or standing usually helps to relieve symptoms within 10 to 15 minutes, allowing individuals to breathe normally again.
PND is often a symptom of underlying heart, lung, or neurological issues. Heart disease, for example, can cause PND when the heart struggles to efficiently pump the extra blood from the legs to the lungs while lying down, leading to fluid buildup and pressure on the lungs. Respiratory conditions, such as airway and lung disorders, can also cause PND, with symptoms often worsening at night. Neurological issues, like central sleep apnea, can affect the body's respiratory drive, disrupting breathing during sleep.
Sleep apnea, a common cause of PND, occurs when the airway is blocked or when the brain fails to signal the body to breathe correctly during sleep. This can lead to interrupted sleep and impact an individual's mental health and quality of life. PND can also be caused by lung or respiratory disorders, heart failure, and other medical conditions.
Treatment for PND depends on the underlying cause. For respiratory disorders, long-term asthma control medications can help reduce breathlessness. In cases of sleep apnea, a continuous positive airway pressure (CPAP) machine with supplemental oxygen may improve breathing. Lifestyle changes, such as avoiding caffeine and alcohol before bed and maintaining a regular sleep schedule, can also help improve sleep quality and reduce PND symptoms.
If you are experiencing PND, it is important to consult a healthcare provider. They can help determine the cause of your symptoms and recommend appropriate treatments or refer you to a sleep specialist.

Underlying health conditions: orthopnea and dyspnea can be caused by heart or lung conditions, obesity, and more
Orthopnea is a feeling of breathlessness when lying flat that is alleviated when sitting or standing up. It is often a symptom of an underlying heart condition, such as congestive heart failure, but it can also be caused by lung conditions, obesity, or other factors. Dyspnea, or shortness of breath, is a common symptom that can accompany orthopnea. It is characterised by difficulty breathing or feeling like one cannot get enough air. Like orthopnea, dyspnea can be caused by heart or lung conditions, obesity, or other factors.
Heart conditions that can cause orthopnea and dyspnea include heart failure, pulmonary hypertension, and abnormal heart rhythm (arrhythmia). Heart failure is the most common cause of orthopnea and occurs when the heart muscle cannot pump adequately enough to meet the body's need for oxygen-rich blood. Obesity can also contribute to orthopnea and dyspnea, as it is linked to inflammation, which may affect lung tissue, and heart disease.
Lung conditions that can cause orthopnea and dyspnea include severe pneumonia (a lung infection), fluid surrounding the lung (pleural effusion), pulmonary embolism (a blood clot in the lung), and allergic pneumonitis. Sleep apnea, a disorder affecting breathing during sleep, can also cause orthopnea and dyspnea.
Other factors that can cause orthopnea and dyspnea include anxiety, asthma, allergies, anemia, lack of exercise, medication, and extreme temperatures. Intense exercise or having a cold can also cause temporary dyspnea. It is important to note that orthopnea and dyspnea can be symptoms of serious underlying health conditions, so seeking medical advice is crucial.

Treatment options: lifestyle changes,
If you are experiencing shortness of breath while sleeping, it is important to identify the underlying cause. Shortness of breath while lying down is called orthopnea, and when it occurs after a few hours of sleep, it is called paroxysmal nocturnal dyspnea. This could be indicative of a more serious medical condition, such as heart failure or pulmonary hypertension, which requires immediate medical attention. Other possible causes include asthma, COPD, pneumonia, sleep apnea, and allergies.
Once the underlying cause is identified, treatment can be administered accordingly. Treatment options for shortness of breath while sleeping can include lifestyle changes, medication, and surgery.
Lifestyle Changes
- Losing weight: Obesity can be a contributing factor to shortness of breath, and weight management can help alleviate the symptoms.
- Quitting smoking: Smoking is a common trigger for respiratory issues, and quitting can help improve breathing.
- Avoiding exposure to pollutants, allergens, and environmental toxins: Reducing exposure to these irritants can help prevent allergic reactions and improve respiratory health.
- Managing underlying health conditions: Conditions such as asthma, COPD, or bronchitis often have recommended treatment plans that can help alleviate shortness of breath.
- Pulmonary rehabilitation: Therapy that teaches techniques to manage breathlessness and improve overall well-being.
- Cognitive behavioral therapy (CBT): Therapy that helps address stressful situations and factors that cause or worsen breathlessness.
- Breathing exercises: These exercises can strengthen lung functioning and help manage shortness of breath.
- Sleep positioning: Propping yourself up with pillows while sleeping can help keep the airways more open.
Medication
- Inhalers: For conditions such as COPD, inhalers can help open airways and improve breathing.
- Antibiotics: For infections such as pneumonia, antibiotics can help treat the underlying cause and alleviate shortness of breath.
- Steroids: For asthma, steroids can help reduce inflammation and improve breathing.
- Statins: Cholesterol-lowering drugs can help improve cardiovascular health and reduce the strain on the heart.
- Beta-blockers: Used to treat high blood pressure, these medications can help improve cardiac function.
Surgery
In some cases, surgery may be necessary to treat underlying conditions contributing to shortness of breath. This could include heart surgery for heart failure or the implantation of medical devices such as pacemakers.
It is important to consult with a healthcare professional to determine the underlying cause of your shortness of breath and receive personalized treatment recommendations.

Frequently asked questions
There could be several reasons for this, including sleep apnoea, paroxysmal nocturnal dyspnea, or laryngospasm. Sleep apnoea involves the narrowing of airways as you sleep, leading to decreased oxygen levels and the need to take deeper breaths. Paroxysmal nocturnal dyspnea is a feeling of being unable to breathe an hour or two after falling asleep. Laryngospasm involves the closure of the vocal cords due to reflux of acidic stomach contents.
If you are experiencing shortness of breath only when you are asleep, it is recommended that you see a sleep specialist. They will be able to take a history and determine the type of sleep study that would be most useful for you. If you are experiencing paroxysmal nocturnal dyspnea, sitting upright or getting out of bed usually helps.
The underlying causes of shortness of breath when sleeping can vary. Some common causes include heart failure, obesity, asthma, anxiety, and sleep apnea.
