Sleep is important for heart health, and the position in which one sleeps can affect the quality of sleep and overall health. While the amount of sleep one needs varies from person to person, the American Heart Association recommends that adults get at least seven hours of sleep per night. Sleeping on the left side, for example, is known to help blood flow in pregnant women, while people with heart failure often experience shortness of breath when sleeping on their left side. Sleep apnea, which involves difficulty breathing during sleep, can lead to serious health issues such as high blood pressure, weight gain, diabetes, heart attack, and stroke. Heart palpitations at night can also be caused by various factors such as sleep position, alcohol, caffeine, nicotine, stress, or hormones.

What You'll Learn
Sleep position and heart health
Sleep is essential for maintaining optimal heart health. However, the position in which one sleeps can also have an impact on heart health.
Back sleeping
Back sleeping, or sleeping supine (face-up), can worsen sleep apnea, a condition where breathing stops and restarts during sleep. Sleep apnea affects cardiovascular health by triggering a stress response in the body as it works harder to pull in air. It can also raise carbon dioxide levels in the blood and interfere with deep sleep. Obstructive sleep apnea has been associated with irregular heartbeats, high blood pressure, and an increased risk of stroke. Therefore, avoiding sleeping on your back may reduce the severity of apnea and its associated risks.
Side sleeping
Side sleeping is generally considered a better alternative to back sleeping. However, there is some controversy regarding whether sleeping on the left or right side is more beneficial for heart health.
Sleeping on the left side is recommended for pregnant women as it helps with blood flow and keeps the uterus off the liver. It is also known to benefit people with gastroesophageal reflux disease (GERD) or acid reflux by aiding in faster esophageal clearance. However, some studies suggest that left-side sleeping may negatively affect the heart by causing slight shifts in its position, leading to changes in ECG readings. These changes are attributed to the re-positioning of the heart and do not affect its electrical function. More research is needed to understand the potential risks associated with left-side sleeping for people with heart conditions.
On the other hand, right-side sleeping is preferred by individuals with heart failure or heart muscle disease as they often experience worsened shortness of breath when sleeping on their left side. Right-side sleeping is also commonly practised by those with heartburn, as it elevates the stomach and may encourage emptying. While researchers have not confirmed its benefits for reflux, it is considered harmless to try.
Stomach sleeping
Stomach sleeping is widely regarded as the least healthy sleep position. It can obstruct the airway, leading to sleep apnea, and is also considered an unhealthy position for the neck and spine.
In conclusion, while personal preference and comfort play a significant role in sleep position, it is important to be aware of the potential impacts on heart health. More research is needed to definitively conclude the best sleep positions for specific conditions, but making sleep a priority and experimenting with different positions can help improve overall heart health and well-being.

Sleep apnea and heart health
Sleep is essential for heart and brain health. Experts say that sleep position can be significant in certain situations, although sleep position is generally a matter of personal preference. People with heart failure, for instance, often experience shortness of breath that worsens when they sleep on their left side, so they may prefer their right. On the other hand, sleeping on the left side is known to help blood flow in pregnant women and may be better for people with gastroesophageal reflux disease (GERD).
Sleep apnea is a common sleep disorder that can significantly impact heart health. It is characterized by snoring, disrupted sleep, and breathing pauses during sleep. These breathing disruptions can last at least 10 seconds and occur frequently throughout the night, causing oxygen deprivation in the body. Obstructive sleep apnea (OSA) occurs when the soft tissue in the throat relaxes and blocks the airway, while central sleep apnea happens when the brain struggles to regulate breathing during sleep.
Sleep apnea has been linked to several cardiovascular complications. It increases the risk of cardiovascular disease (CVD) and is associated with higher rates of high blood pressure, stroke, and coronary artery disease. Sleep apnea can also lead to left ventricular diastolic dysfunction, which raises the likelihood of heart failure. Additionally, it is a risk factor for atrial fibrillation, a heart rhythm disorder, and sudden cardiac death.
People with heart conditions or risk factors should be screened for sleep apnea to prevent complications. Sleep apnea can worsen heart problems, creating a cycle where heart issues exacerbate sleep apnea. Treatment for sleep apnea is essential to break this cycle and improve heart health.
Furthermore, sleep apnea often co-occurs with cardiovascular disease. Studies suggest that between 40% and 80% of people with cardiovascular disease also have sleep apnea. Sleep apnea is also more prevalent in individuals at high risk for heart attacks. Therefore, it is crucial for those with heart-related concerns to prioritize sleep and seek medical advice if they suspect they have sleep apnea.

Heart palpitations at night
Experiencing heart palpitations at night can be alarming, but they are usually harmless and are very common. They can feel like your heart is pounding, fluttering, skipping a beat, or racing, and you are more likely to notice them when you aren't distracted during the day.
Causes
There are many factors that can cause heart palpitations at night, including:
- Alcohol consumption, especially if consumed later in the day or at night
- Caffeine consumption, especially in the afternoon or evening
- Dehydration, which can cause the heart to beat faster and more forcefully
- Sleep position: People who sleep on their backs may be more prone to palpitations due to pressure changes, and left-sided sleepers may experience them more due to the shorter distance between the heart and the chest wall
- Stress and anxiety: Stress is more likely to occur at night when we start thinking about worrying or stressful events in our lives, and people with chronic anxiety are more prone to developing arrhythmias
- Medication: Certain medications can cause heart palpitations
- Sleep apnea: This causes pauses or reductions in breathing during sleep, which can stress the heart and lead to palpitations
- Nicotine
- Hormones
- Thyroid disorders
- Heart disease
Relief and Treatment
If you are experiencing heart palpitations at night, you can try the following:
- Breathe deeply: Try pursed-lip breathing techniques, meditation, and other relaxation techniques to reduce stress
- Drink a glass of water: Dehydration can cause heart palpitations, so ensuring you are well-hydrated can help
- Change your sleep position: Try rolling over in bed, sitting up, or going for a short walk while taking deep breaths
- Limit stimulants and manage stress before bed
- Avoid alcohol, caffeine, and nicotine, especially before bed
- Avoid eating a large meal before bed, especially foods high in fat, carbs, salt, or sugar
If you are concerned about heart palpitations, it is important to speak to your doctor, who can help manage your symptoms and may recommend further tests to check your heart health.

Sleep and heart disease risk
Sleep is critical for maintaining good heart health. The American Heart Association recommends 7-9 hours of sleep per night, but sleep disorders can make it difficult to get a healthy amount of rest. Sleep disorders are conditions that affect the quality, timing, and amount of sleep, and they have been linked to a higher risk of cardiovascular disease. Poor sleep can cause major cardiovascular disease risk factors, including obesity, high blood pressure, and diabetes.
Insufficient or irregular sleep can negatively influence diet, stress, and other lifestyle factors that can raise the risk of cardiovascular disease. For example, interrupted or insufficient sleep cycles can lead to higher-than-average blood pressure levels, which can put a strain on the heart and blood vessels over time. Poor sleep patterns can also upset appetite-regulating hormones, leading to overeating and weight gain, which are risk factors for heart disease.
Additionally, excessive daytime sleepiness, which is a symptom of many sleep disorders, can lead to a greater risk of cardiovascular disease. Sleep deprivation and sleep disorders have also been linked to increased inflammation in the body, which can elevate the risk of cardiovascular issues. Sleep apnea, a common but underdiagnosed sleep disorder, affects how much oxygen the body gets during sleep and increases the risk for health problems such as high blood pressure, heart attack, and stroke.
While sleep position may not seem as important as sleep duration and quality, it can also impact heart health. Sleeping on the left side, for instance, might be better for people with gastroesophageal reflux disease (GERD), as it helps with blood flow. However, people with heart failure often experience shortness of breath that worsens when they sleep on their left side, leading many to prefer sleeping on their right side.
Overall, getting good sleep is crucial for maintaining heart health and reducing the risk of heart disease.

Sleep quality and heart health
Sleep is essential for maintaining a healthy heart. The American Heart Association (AHA) has included sleep in its heart health checklist, recognising its significance as a risk factor for cardiovascular disease. Indeed, studies have shown that poor sleep is associated with a higher risk of cardiovascular issues, including heart attack, abnormal heart rhythms, and coronary artery disease.
The relationship between sleep and heart health is bidirectional. Poor sleep can influence food choices, leading to a preference for less heart-healthy comfort foods high in saturated fat and sugar. This can then contribute to further sleep difficulties, creating a cycle. Additionally, poor sleep can impact physical activity levels, with individuals experiencing sleeplessness often feeling less motivated to engage in exercise, which can negatively affect heart health.
Sleep quality and duration both play a role in heart health. While the recommended sleep duration for adults is seven to nine hours per night, it is important to prioritise sleep quality as well. Sleep disorders such as insomnia and sleep apnea can disrupt sleep quality and have been linked to high blood pressure and heart disease. Sleep apnea, characterised by snoring, gasping for breath, and daytime sleepiness, can cause significant stress to the cardiovascular system due to oxygen deprivation.
Furthermore, sleep position may also impact heart health. While generally a matter of personal preference, certain positions might be beneficial for specific conditions. For instance, sleeping on the left side is known to help blood flow in pregnant women and may be preferable for those with gastroesophageal reflux disease (GERD). On the other hand, people with heart failure often experience worsened shortness of breath when sleeping on their left side, opting instead for their right.
In conclusion, sleep quality and duration are vital for maintaining heart health. Getting sufficient, high-quality sleep can help protect against cardiovascular disease, while poor sleep can increase the risk of heart-related issues. By prioritising sleep and addressing any sleep disorders or position-related discomfort, individuals can support their heart health and overall well-being.
