Insomnia is a common sleep problem that affects many people each year. It’s crucial to understand how it relates to heart disease and other heart-related disorders, as well as the negative impact of poor sleep on general health. We’ll discuss what sleep apnea is and whether or not bad sleeping habits might cause heart illnesses such as a heart attack or stroke in this blog article.

Does Sleep Deprivation Affect Heart Health?

Sleep problems, such as sleeplessness and interrupted sleep, have been linked to an increased risk of heart disease.

Sleep is when the body repairs and recuperates. Non-rapid eye movement (NREM) sleep stages include a decrease in heart rate, blood pressure, and breathing rate. These modifications alleviate stress on the heart, allowing it to repair from wear incurred throughout the day.

Those who don’t get enough sleep spend less time in the deep phases of NREM sleep, which are beneficial to the heart. This problem may also impact those whose sleep is frequently disrupted.

Sleep deprivation has been linked to a number of cardiac issues, including high blood pressure, high cholesterol, heart attack, obesity, diabetes, and stroke.

Sleep and Blood Pressure

During good sleep, blood pressure drops by about 10-20 percent. Nocturnal dipping is the term used to describe this phenomenon, which has been linked to cardiac health in studies.

Sleep deprivation, whether caused by sleep deprivation or disturbances in sleeping, is linked to non-dipping blood pressure levels. Poor sleep has been linked to non-dipping blood pressure levels.

In fact, nocturnal blood pressure has been found to be a better predictor of heart disease than daytime high blood pressure. Non-dipping has been linked to an increased incidence of stroke and heart attack. It’s also been linked to kidney problems and decreased cerebral blood flow.

Sleep deprivation has been linked to higher daytime blood pressure, according to several studies. Although sleep loss affects everyone differently, it is associated with increased blood pressure in certain groups of people. Chronic lack of sleep is linked to high blood pressure in middle-aged individuals, according to surveys.

Sleep and Coronary Heart Disease

Coronary heart disease is the most frequent cause of death in the United States. Atherosclerosis causes plaque to accumulate in the arteries, hardening and narrowing them as a result of this process. This reduces the heart’s ability to obtain adequate blood and oxygen flow.

Sleep deprivation has been linked to atherosclerosis. Sleep deprivation is accompanied by the presence of white blood cells from the immune system in the arteries, which indicates inflammation. Chronic inflammation is promoted by insufficient sleep, resulting in plaque accumulation and arterial stiffness.

Sleep deprivation’s connection to heart disease is also attributed to its influence on blood pressure, which is linked to sleep deprivation. Hypertension puts strain on the arteries and makes them less effective in transporting blood to the heart, contributing to heart illness.

Sleep and Heart Failure

Heart failure occurs when the heart does not pump enough blood throughout the body. Heart failure is defined as a condition in which the heart fails to pump adequate amounts of blood throughout the body. The study of almost 400,000 individuals revealed significant connections between sleeping difficulties and heart failure.

People who slept fewer than seven hours each night had an increased risk of heart failure, according to a study published in the Journal of Physical Activity and Health. Heart failure was also more prevalent among those who exhibited indicators of poor sleep such as insomnia symptoms, daytime drowsiness, snoring, and being an evening person. The more signs of bad sleep one have, the higher their risk of heart failure is.

Sleep and Heart Attacks

A heart attack is a condition in which blood flow to the heart is blocked, resulting in damage and death. Because of the harm that arises when the heart does not receive enough oxygen, myocardial infarctions can be fatal.

Sleep deprivation raises the chance of a heart attack. According to one study, individuals who slept less than six hours each night had a 20% higher risk of suffering a heart attack. NREM sleep, on the other hand, aids in the recovery and slowing down of the heart. Inadequate sleeping might disrupt the balance of these phases, increasing the likelihood of having a heart attack.

Sleep interruptions have been linked to a higher risk of heart attacks. Because both heart rate and blood pressure can rise rapidly when waking up, frequent sleep disruptions can cause cardiac stress and perhaps a heart attack.

Sleep and Stroke

A stroke occurs when blood flow to the brain is blocked, causing brain cells to die as a result of a lack of oxygen. A blood clot or plaque blocking an artery is responsible for ischemic strokes. A temporary ischemic attack (TIA) (also known as a mini-stroke) occurs when a blood vessel gets blocked for only a brief period.

According to studies, sleep deprivation has been connected to an increased risk of stroke. Sleep deprivation raises blood pressure, making it the most important stroke risk factor, according to a study published in the journal Sleep Medicine. According to research published in the journal Sleep Medicine, insufficient sleep can also make blockages more likely and cause small strokes or strokes.

Sleep and Obesity

Overweight and obesity are strongly linked to a range of cardiovascular and metabolic problems, including hypertension, diabetes, high cholesterol, heart disease, heart attack, and stroke.

In several types of research, a lack of sleep has been linked to obesity. Individuals who get less than seven hours of sleep each night are more likely to have a higher body mass index (BMI) or be overweight. Sleep aids in the regulation of appetite hormones, and insufficient or disturbed sleep might cause people to eat more and develop high-calorie food cravings.

Sleep and Type 2 Diabetes

Type 2 diabetes is a long-term condition in which blood sugar, often referred to as blood glucose, is excessively high owing to a flaw in the body’s ability to break down sugar. Blood sugar levels that are higher than usual harm blood vessels and have an adverse effect on heart health. Individuals suffering from diabetes are twice as likely to die from heart disease or stroke23 as those who do not have this illness.

Sleep deprivation has been linked to worse glucose metabolism, according to research. Sleep deprivation is connected with prediabetes, a condition in which blood sugar control is poor despite normal or elevated glucose levels. People who have diabetes and sleep problems may have a harder time controlling their blood sugar. Narrowed arteries over time can be caused by insufficient or restless sleep in individuals with type 2 diabetes.

Sleep and Heart Rate

The heart rate falls during NREM sleep stages and then rises as you prepare to wake up.

According to research, sleep deprivation, which entails abrupt arousals, can result in a significant increase in heart rate. People who have sleep issues are also more likely to report an irregular heartbeat, according to studies. As a consequence of this, insufficient sleep might be linked to cardiac palpitations for these reasons.

People who have frequent night terrors are more likely to experience an abnormal heart rhythm, according to researchers. It’s conceivable that recurring dreams cause your heart rate to rise. Recurring dreams could raise your heart rate, and if you have a nightmare while sleeping, you might awake to feel as if your heart is pounding.

The health effects of insomnia

According to previous studies, around 30% of the US population suffers from insomnia symptoms that have been linked to an increased risk of diabetes and other illnesses. According to the American Academy of Sleep Medicine (AASM), only 10% of individuals in the United States have a chronic sleep problem.

Insomnia symptoms include:

  • difficulty falling asleep
  • difficulty staying asleep throughout the night
  • waking up too early in the morning

Chronic sleeplessness is defined as occurring at least three times each week for at least three months. According to the AASM, “Chronic insomnia may have a serious impact on physical, mental, and emotional health by lowering daytime alertness, mood, memory function, and cognitive performance.”

“Sleep is good for the body in general,” said Dr. Joyce Oen-Hsiao, a cardiologist at Yale Medicine. “It allows the body to relax and recover after a hard day’s work. Being able to rest your body might help you burn calories faster and reduce stress, both of which can improve cardiac health.”

“There’s a fascinating relationship between sleep-wake cycles and cardiovascular control,” says Deena Kuruvilla, MD, a Yale Medicine neurologist.

“For example, non-rapid eye movement sleep has been shown in studies to lower blood pressure and heart rate while increasing parasympathetic activity throughout the night. Insomnia may have an impact on circadian heart regulation and cause cardiovascular disease and stroke as a result.”

Cognitive-behavioral therapy is considered the most effective treatment for chronic sleeplessness, according to the AASM. This technique involves behavioral techniques such as developing a consistent sleep routine and cognitive ideas like replacing pessimistic thoughts about not sleeping with more realistic expectations.

“The National Sleep Foundation says that adults require 7 to 9 hours of sleep each night,” Bill Fish, a certified sleep coach, adds. “You aren’t if you aren’t getting enough rest. You’re probably feeling anxious and don’t have time for your heart to be at ease.”

“However,” he added, “insomnia can also be viewed as a ‘check engine light’ type of problem. If you’re having difficulty falling asleep on a nightly basis and it isn’t normal for you, your body may be attempting to communicate with you. If this issue persists for more than two weeks, it’s suggested that you see your doctor talk about things further.”

Sleep Disorders and Heart Health


Sleep disorders, particularly sleeplessness, have been linked to poor heart health. Insomnia is one of the most common sleep issues, and it frequently occurs along with insufficient sleep, which raises cardiovascular health concerns.

Obstructive sleep apnea (OSA) is a breathing disorder that has been linked to heart disease, obesity, diabetes, stroke, and high blood pressure. Individuals with OSA who have an airway blockage during sleep suffer from recurrent interruptions in breathing.

One of the reasons why OSA is linked to a variety of cardiac problems is that it causes interrupted breathing. In addition, irregular breathing reduces the amount of oxygen in circulation, worsening OSA’s impact on heart health.

Restless leg syndrome (RLS) and periodic limb movement disorder are two sleep-related illnesses that have been linked to heart problems. While the mechanism behind this connection is unknown, it may be because to abnormal activation of the cardiovascular system, which causes increased and changing heart rate and blood pressure in people with these conditions.

Heart problems have been connected to circadian rhythm sleep disorders, in which the body’s internal clock is out of sync with daytime and nighttime. People who work night shifts and must sleep during the day are at risk of a variety of illnesses, including high blood pressure, obesity, diabetes, and cardiac issues like stroke or heart attack.

Sleeping Too Much and Heart Health

Despite the fact that sleep deprivation’s health effects are well-known, numerous studies have found a link between excessive sleeping, which is defined as more than nine hours of sleep per night, and cardiac disease.

It’s been shown that individuals who consistently experience problems with their sleep do not live as long as those who get less of it. It appears, however, that underlying health issues that cause aberrant sleep are also linked to an increased risk of heart disease. Nonetheless, this finding serves as a stern reminder that there is no link between more sleep and improved health.

Sleep for People With Heart Disease

Sleep deprivation has been linked to a variety of health problems, including heart damage. It’s critical for those who have cardiovascular concerns to get enough sleep. People at high risk for heart attacks and other cardiac illnesses who slept longer had a decreased chance of suffering one.

Unfortunately, sleep problems can be caused by a variety of cardiac conditions. Diabetes, for example, can cause frequent nocturnal urination and other cardiovascular issues may produce chest discomfort when attempting to fall asleep. Worry and anxiety about one’s cardiac health might also keep one from relaxing and going to sleep easily.

It’s critical to consult with your doctor about heart-healthy sleep since a number of elements might influence both sleeping patterns and heart health. A medical professional can help you come up with a unique plan to boost your sleep while also addressing other lifestyle issues such as nutrition and exercise, which are critical for your heart and general health.


Is insomnia a symptom of congestive heart failure?

Yes, sleeplessness isn’t a sign of congestive heart failure.

How do you treat an insomnia attack?

There is no one-size-fits-all solution to this issue since the treatment for sleeplessness will vary depending on the cause. Some typical treatments for insomnia include adjustments to sleeping habits, drug therapy, and cognitive-behavioral therapy.

Can chest pain be from lack of sleep?

Yes, sleeplessness can induce chest pain. Because a person doesn’t get enough sleep, their heart rate and blood pressure might become irregular, causing chest discomfort. Sleep loss may also cause stress and anxiety, both of which are linked to chest pain.

Can you be awake during a heart attack?

No, you can’t be conscious during a heart attack. When the blood supply to the heart is suddenly cut off, the muscle tissue in the heart dies. This process is irreversible, so if you believe you’re having a heart attack, go immediately to see a doctor.

Conclusion thoughts

Poor sleep has been linked to a variety of heart diseases, and research suggests it might contribute to cardiac issues. However, there are methods to enhance good heart-healthy sleep. People who sleep for more than nine hours each night have an increased risk of heart disease, so aim for around eight hours of shut-eye per night. Furthermore, those with heart disease should discuss their options for improving their sleep with their doctor.
