Can Sleep Apnea Cause Depression?

People with sleep apnea may be at risk for developing depression. While the two conditions share some symptoms, they are separate medical conditions.

Sleep apnea is a condition that can cause disruptions in your breathing pattern during sleep. These disruptions can occur several times throughout the night and can last for a few seconds to a minute. If you have sleep apnea, you may not be aware of these disruptions because they can happen while you are asleep.

Sleep apnea can cause daytime fatigue, irritability, and difficulty concentrating. It can also increase your risk for accidents and injuries. In addition, sleep apnea has been linked to depression.

Depression is a mood disorder that causes a persistent feeling of sadness and loss of interest in activities. Depression can interfere with your ability to work, study, eat, and sleep. It can also lead to suicide.

Sleep apnea and depression share some common symptoms, such as fatigue and difficulty concentrating. However, it is not clear if sleep apnea causes depression or if depression leads to sleep apnea. It is also possible that both conditions are caused by another underlying factor, such as a medical condition or lifestyle choices.

What is sleep apnea?

Sleep apnea is a sleep disorder in which your breathing is interrupted during sleep. The most common type, obstructive sleep apnea, occurs when your throat muscles intermittently relax and block your airway. This interruption can happen many times throughout the night, preventing you from reaching deep, restful sleep.

While often associated with snoring, not everyone who has sleep apnea snores. However, people with sleep apnea are more likely to experience other symptoms, such as gasping for air during sleep, waking up with a headache or dry mouth, and feeling tired during the day.

Sleep apnea can occur at any age, but it is more common in adults over the age of 40. It is also more common in men than women. People who are overweight or have a family history of sleep apnea are also at increased risk.

If left untreated, sleep apnea can lead to serious health problems, including high blood pressure, heart disease, stroke, and depression.

Symptoms of sleep apnea

Symptoms of sleep apnea vary from person to person. They may be mild or severe. If you have mild sleep apnea, you may not be aware of it. Symptoms can include:
-Loud snoring
-Gasping or choking during sleep
-Restless sleep
-Waking up frequently during the night to urinate
-Sleepiness or fatigue during the day
-Memory problems

Causes of sleep apnea

There are three main types of sleep apnea: obstructive, central, and mixed. Obstructive sleep apnea is the most common type. It happens when your throat muscles intermittently relax and block your airway while you sleep. Central sleep apnea is caused by a problem with your brain sending the right signals to your breathing muscles. Mixed sleep apnea is a combination of both central and obstructive sleep apneas.

Sleep apnea may be caused by a number of factors, including:
-Excess weight. People who are overweight or obese are more likely to havesleep apnea.
-Anatomy. Certain physical characteristics can make you more prone tosleep apnea, such as a naturally small airway, large tonsils or adenoids,a large tongue, or an overextended soft palate.
-Family history. If you have relatives with sleep apnea, you may be more likely to develop the condition yourself.
-Narrowed airway due to swelling from allergies or a cold. Enlarged tonsilsor adenoids can also cause obstruction by blocking the airway.
-Smoking tobacco products. Smoke irritates and inflames the upper airway, which narrows it and makes it more likely to collapse during sleep.
-Use of alcohol, sedatives, or tranquilizers before bedtime

Risk factors for sleep apnea

There are many risk factors for sleep apnea, including being overweight, having a large neck circumference, smoking, and drinking alcohol However, sleep apnea can also occur in people who are not overweight and do not have any of these risk factors.

Some studies have found that people with sleep apnea are more likely to be depressed than people without sleep apnea. It is not clear if sleep apnea causes depression or if depression causes sleep apnea.

Diagnosis of sleep apnea

There are three primary ways to diagnose sleep apnea:

1. Sleep study: You’ll spend a night at a sleep center, where your breathing will be monitored while you sleep.

2. Home sleep test: You’ll use a portable monitor to record your breathing and other data while you sleep at home.

3. Clinical exam: Your doctor will ask about your medical history and symptoms, and conduct a physical exam of your head and neck.

Treatment of sleep apnea

There are a number of ways to treat sleep apnea, depending on the underlying cause. Many people can improve their sleep apnea with lifestyle changes, such as losing weight, quitting smoking and avoiding alcohol and sedatives before bedtime. Some people may need to use a continuous positive airway pressure (CPAP) machine to help keep their airway open while they sleep. In severe cases, surgery may be necessary to correct the problem.

Can sleep apnea cause depression?

Depression and sleep apnea often go hand-in-hand. In fact, studies have shown that people with untreated sleep apnea are more likely to suffer from depression than those who don’t have the condition. There are a few different reasons why sleep apnea can cause or contribute to depression.

First, sleep deprivation can have a major impact on your mood. When you don’t get enough rest, it can be difficult to deal with the day-to-day stressors of life. This can lead to feelings of depression.

Second, sleep apnea can cause physical changes in the brain that can lead to depression. Studies have shown that people with sleep apnea have lower levels of serotonin, a chemical that helps regulate mood.

Third, sleep apnea can contribute to feelings of isolation and loneliness. When you’re not getting enough rest, it’s tough to participate in activities you enjoy and interact with others. This can sometimes lead to depression.

If you think you might be suffering from depression, it’s important to talk to your doctor about your symptoms and whether or not treatment for sleep apnea could help.


To conclude, sleep apnea can cause depression. However, more research is needed to completely understand the relationship between the two. If you think you may have sleep apnea, talk to your doctor.
