How Does Sleep Apnea Affect Your Heart?

Sleep apnea is a condition that affects your breathing while you sleep. Rather than getting a good night’s sleep, this condition interrupts your breathing. It is a condition that affects millions of people worldwide. While it’s known to cause daytime fatigue and impair one’s quality of life, what many don’t realize is that sleep apnea can have a profound impact on your heart health. 

How Does Sleep Apnea Affect Your Heart?

Understanding Sleep Apnea

Sleep apnea comes in two primary forms: obstructive sleep apnea (OSA) and central sleep apnea (CSA). OSA is more common and occurs when the muscles in the throat relax excessively during sleep, leading to blockages in the airway. CSA, on the other hand, is related to the brain’s inability to signal the muscles to breathe. As a result, you can have irregular breathing patterns.

The Silent Saboteur

Sleep apnea is often referred to as a silent saboteur because its effects can go unnoticed for years. While loud snoring is a common symptom, many people remain unaware of their condition. Over time, untreated sleep apnea can take a toll on your heart.

How Sleep Apnea Affects Your Heart

Sleep apnea is more than just noisy snoring. It’s a condition that can greatly impact your heart health.

Increased Risk of Hypertension

One of the most significant ways sleep apnea affects the heart is by increasing the risk of hypertension, or high blood pressure. The repeated drops in blood oxygen levels that occur during sleep apnea can put additional stress on the cardiovascular system. This can lead to long-term elevated blood pressure, which is a known risk factor for heart disease and stroke.

Irregular Heartbeats

Sleep apnea has been linked to arrhythmias, which are irregular heartbeats. The disruption in oxygen supply can affect the heart’s electrical activity. This can potentially lead to arrhythmias, such as atrial fibrillation. These irregular heart rhythms can have serious consequences, including an increased risk of stroke.

Heart Disease

Sleep apnea can also increase your risk of heart disease. The chronic lack of oxygen can lead to the development of atherosclerosis. This is the hardening and narrowing of the arteries. Consequently, this condition can ultimately result in heart attacks and other cardiac issues.

Heart Failure

Heart failure is a condition in which the heart cannot pump blood effectively to meet the body’s needs. It is another potential consequence of untreated sleep apnea. The strain placed on the heart due to repeated oxygen drops and increased blood pressure can weaken the heart muscle over time.

Sleep-Heart Interactions

It’s essential to recognize the intricate interplay between sleep and heart health. Poor sleep quality, a common result of sleep apnea, can disrupt the body’s circadian rhythms. This can lead to a range of health problems, including those related to the heart.

Seeking Help and Treatment

The good news is that there are effective ways to manage sleep apnea and reduce its impact on heart health. Lifestyle changes, such as weight loss and avoiding alcohol and sedatives, can help. 

Continuous positive airway pressure (CPAP) therapy is a common treatment for sleep apnea, which involves wearing a mask during sleep to maintain an open airway. Dental devices, surgery, and positional therapy are also options, depending on the severity and type of sleep apnea.
