What Is The Connection Between Sleep Apnea And High Blood Pressure

Bad Sleep Cause High Blood Pressure

Sleep apnea, or obstructive sleep disorder, causes a reduction of airflow while you sleep the most tell tale sign is snoring, as well as gasping for air, waking up frequently, and chronic daytimefatigue.

A national multi sleep study of over 6,000 men and women, conducted through the John Hopkins School of Public Health found a correlation between high blood pressure and sleep apnea. While more severe sleep apnea, with over 30 lapses in breathing, presents the highest risk, this sweeping study found that even modest sleep apnea is associated with an increased risk of high blood pressure.

Are You At Risk

High blood pressure usually doesnt have any symptoms so its important to get checked regularly.

Healthy adults aged over 40 should have their blood pressure checked at least once every five years, the NHS says.

But this should be once a year if you have any of the risk factors described above.

Blood pressure readings are done at your GP surgery, some pharmacies and some workplaces.

People in England aged between 40 and 74 will also be offered a reading as part of their NHS Health Check.

You can also test your blood pressure at home using a home testing kit.

Can High Blood Pressure Make You Feel Tired

Feeling tired may be connected to high blood pressure itself. It may also be a symptom of a coexisting condition. Left untreated, high blood pressure can lead to several serious complications that can cause fatigue.

Lets take a closer look at some of the ways that high blood pressure may result in feelings of fatigue or tiredness.

Sleep And Type 2 Diabetes

Type 2 diabetes is a chronic condition in which the level of blood sugar, also known as blood glucose, is too high due to the bodys inability to process sugar properly. Excess blood glucose damages blood vessels, negatively affecting cardiovascular health. People with diabetes are twice as likely to die from heart disease or stroke than people without this condition.

Many factors affect blood sugar, but studies have found that a lack of sleep worsens glucose metabolism. Poor sleep is associated with prediabetes, a a type of glucose intolerance that does not meet the parameters for diabetes. People already diagnosed with diabetes who have insufficient or restless sleep may have a harder time controlling their blood sugar. Impaired sleep may also worsen the hardening of arteries in people with type 2 diabetes.

Insomnia & Sleep Deprivation

Research shows that your chances of developing high blood pressure increase significantly when you sleep less than seven hours of sleep each night. Insomnia is a condition that prevents you from falling asleep and achieving uninterrupted sleep. Now it turns out that it could be to blame for high blood pressure, too.

In a groundbreaking 2015 study, Chinese researchers found that those who took an average of 14 minutes longer to fall asleep increased their chances of high blood pressure by 300 percent. The inability to fall and stay asleep is one of the main driving causes of hypertension.

Sleep Apnea And High Cholesterol

The same study from above found that frequent snorers suffered from the HDL cholesterol decay. The study displays connection between high cholesterol and snoring, which means that sleep apnea patients who snore and gasp for air may be more prone to high LDL cholesterol and serious cardiovascular issues.

There is another study that found connection between sleep apnea and high cholesterol.

Without treatment and CPAP machine, sleep apnea patients have difficulties sleeping without waking up, leading to ultimately poorer sleep quality and high overall cholesterol.

Poor Sleep Hygiene Compromises Your Cholesterol

Our sleep is extremely tied to our overall health. Cholesterol, a chemical that affects our hearts health is only naturally connected to our sleep quality. If you dont trust us, take a look at this study, which found that people who both oversleep and dont have enough sleep have compromised lipid levels.

This extensive study looked at people older than 20. They examined sleep patterns and habits of the subjects, where those who slept less than five hours would risk the peak of triglycerides while the good HDL cholesterol levels would decay in women. However, those who slept longer than eight hours were prone to the same risks. That means its necessary to find balance in everything.

The study discovered that men were less prone to those changes with women, meaning they were exposed to less risk.

Interestingly, another study found that getting an insufficient amount of sleep leads to a drastic LDL level increase, which is bad for our blood and hearts health.

Those who were getting less than six hours per night risked a severe heart disease due to the drastic rise in the LDL cholesterol, increasing the odds for stroke.

Lack Of Sleep Can Lead To High Blood Pressure

The next installment of LIFELINES’ series on high blood pressure and how you can reduce your risk for this condition.

Its no secret that poor sleep can make you grumpy and foggy. When it happens routinely, it can also increase your risk for high blood pressure.

According to the National Sleep Foundation , adults need seven to nine hours of shut-eye each night. However, shift work, jobs, family responsibilities, diet and underlying medical conditions keep millions of people, including many Laborers, from getting the right amount of sleep. When this happens routinely, restorative sleep gets short-changed and blood pressure can climb to unhealthy levels.

What is restorative sleep?

Restorative sleep occurs late in slumber during the last two of sleeps four stages and is essential to health. This is when the body repairs itself. Tissue growth and healing take place, energy is restored, immune and nervous systems are bolstered and, key to controlling blood pressure, stress hormones are regulated. When restorative sleep is habitually cut short, the body can lose this ability, increasing the likelihood for high blood pressure and heart disease.

Sleep For People With Heart Disease

HBP 043- How is High Blood Pressure linked to insomnia or poor sleep

Because sleep deprivation can harm the heart, its important for people with cardiovascular problems to make getting good sleep a priority. Some evidence even indicates that improving sleep may reduce the likelihood of heart attacks or other cardiovascular problems in people who are otherwise at high risk.

Unfortunately, some heart problems can interfere with sleep. For example, diabetes can cause frequent nighttime urination, and other cardiovascular disorders may create chest discomfort when trying to get to sleep. Worry and anxiety about heart health can also make it hard to wind down and fall asleep normally.

Because numerous factors can influence both sleep and cardiovascular health, its most helpful to talk with your doctor about heart-healthy sleep. A doctor can help develop a specific plan to improve your sleep while also addressing other lifestyle factors, such as diet and exercise, that are important for your heart and overall wellness.

What Stops You From Sleeping

With the potential risk of both high blood pressure and heart disease connected to a lack of sleep, it is perhaps worth exploring the causes of your lack of rest. One main cause that is completely treatable could be sleep apnea.

Sleep apnea is a condition which will cause you to stop and start breathing while you are asleep throughout the night. You may not realize that you are doing this. A common sign or symptom would be feeling exhausted when you wake up in the morning and potentially experiencing severe headaches.

Its worth pointing out that during episodes where you stop breathing due to sleep apnea, your brain does release stress hormones. These hormones then raise both your heart rate and your blood pressure. It is for this reason that sleep apnea has been linked to both high blood pressure and potentially heart failure. If you already have difficulty with your heart sleep apnea can make the problem worse as well. Insomnia will trigger a stress response and this will gradually weaken your heart over time.

One study found that through a period of eight years, men with sleep apnea were 58% more likely to develop congestive heart failure compared to those without this particular disorder. While one might expect this to only expect older men, studies also show that adolescents who struggle to sleep well are more at risk of developing cardiovascular issues as well. Furthermore, issues like this in childhood can snowball to become greater problems later on in life.

Symptoms Of Stress And Their Impact On Sleep

Stress doesnt always show itself right away. It may start slowly and quietly, revealing itself as a headache, upset stomach, or just good, old-fashioned fatigue. Your mental health can become affected as depression and anxiety begin to take over. All of that stress starts to build up over time until suddenly, theres no ignoring it anymore. Often, your sleep can be the biggest victim.

Sleep is a chance for the body to rest and regenerate, recharging for the next day to come. Our bodies are only able to survive so long without the opportunity for rest, and a lack of sleep can significantly impair the bodys systems and the way they can work together to keep the body going.

Stress has long been known as a significant deterrent to a healthy nights rest, and if left untreated, the body will slowly give way over time. It opens the door to other, more severe issues, like depression, weight gain, skin problems, decreased sex drive, and heart disease.

Thankfully, there are ways to help.

Sleep Boosts Mental Wellbeing

Given that a single sleepless night can make you irritable and moody the following day, itâs not surprising that chronic sleep debt may lead to long-term mood disorders like clinical depression and generalised anxiety disorder in adults.

When people with anxiety or depression were surveyed to calculate their sleeping habits, it turned out that most of them slept for less than 6 hours a night.

How To Sleep Better

6 Effects of Sleep Deprivation. Visit www ...

If youre experiencing mild, occasional problems with sleep, try these simple strategies from sleep expert Michelle Drerup, PsyD, DBSM.

1. Treat getting enough sleep as if it is as important as taking medicine.

With all the demands on our time every day, you might put a good nights rest at the bottom of your priority list. But Dr. Drerup says we need to schedule adequate time for sleep.

Its very easy to stay up late and burn the candle at both ends, she says. However, when you do that, you quickly run into a problem of dealing with sleep deprivation.

2. Keep a consistent wake time.

Wake up at the same time every day, including weekends or days off. Waking at the same time every day will actually help you to sleep better at night. A fixed wake time helps to build a strong desire for sleep throughout wakefulness. This sleep drive gradually builds, and shortening it by sleeping in will make it harder to fall asleep the next night. Sleeping in on the weekend makes it much more difficult to wake up earlier on Monday morning.

It also is important, Dr. Drerup says, to do some relaxing activity such as taking a warm bath or reading a book before bedtime. By making these activities part of your bedtime ritual, you can train yourself to associate these activities with sleep. This association will help you to move more easily into slumber.

3. Put away the smart phones and tablets.

4. If you do wake up during the night, avoid looking at the clock.

Sleep And Heart Failure

Heart failure is when the heart doesnt pump enough blood to supply the body with the blood and oxygen that it needs to function properly. An observational study of over 400,000 people found strong associations between sleeping problems and heart failure.

In that study, people who slept less than seven hours per night had an elevated risk of heart failure. Heart failure was also more common in people who had other indicators of unhealthy sleep including insomnia symptoms, daytime sleepiness, snoring, and being an evening person. The more of these signs of unhealthy sleep that one person had, the higher their likelihood of heart failure.

Could Lack Of Deep Sleep Fuel High Blood Pressure


Missing out on deep sleep can leave you feeling slow-witted and irritable in the morning, but the consequences dont necessarily end there. Over time, too little deep sleep may also take a toll on your heart by contributing to high blood pressure, a new study suggests.

Healthy young and middle-aged adults spend about 20% to 25% of their sleeping hours in the stages known as slow-wave sleep . This sleep phase is considered restorative and has been shown to be important for memory and mental performance.

The new study, which included 784 men over the age of 65, adds to the growing evidence that slow-wave sleep is also essential to our metabolism and heart health. Compared to men who spent at least 17% of their sleep time in the slow-wave phase, those who spent less than 4% in this restful state had 83% higher odds of developing high blood pressure years later, the study found.

What Is The Relationship Between Sleep Apnea And Blood Pressure

Of the two types of sleep apnea, only OSA is linked to high blood pressure. CSA isnt a known cause of hypertension, but it develops in 30 to 50% of people with heart failure.

The prevalence of OSA is estimated to be between 4 and 7% of the general population, but it affects 30 to 40% of people with hypertension. Of people diagnosed with OSA, it is estimated that around half also have high blood pressure.

In healthy individuals, blood pressure naturally lowers by between 10 and 20% at night, a phenomenon that is sometimes referred to as blood pressure dipping. People with severe OSA experience blood pressure dips of less than 10%, which indicates a nondipping blood pressure pattern.

People who have nondipping blood pressure at night face an increased risk for cardiovascular issues. Additionally, many patients with OSA experience a sudden and pronounced elevation of their blood pressure when they wake up in the morning. This morning surge is another factor that may increase risk for cardiovascular disease. Moderate to severe OSA increases all-cause and cardiovascular mortality.

OSA doesnt only affect blood pressure at night. Studies show that daytime blood pressure levels also increase with sleep apnea severity.

Lack Of Sleep Can Contribute To Heart Disease

What Is The Relation Between High Blood Pressure and Sleep?

According to the CDC, routinely getting less than seven hours of sleep is associated with various health problems, including obesity, high blood pressure, coronary artery disease , and stroke.

Sleep affects many bodily functions that can contribute to heart disease, says Nicole Weinberg, MD, a cardiologist at Providence Saint John’s Health Center.

People who don’t get enough sleep are also more likely to skip habits that contribute to a healthy heart, like exercising and eating well. “When you have a good night’s sleep, you’re better able to do those things,” Weinberg says.

Getting enough sleep might be particularly important for people who already have risk factors for heart disease. A 2019 study in the Journal of the American Heart Association found that people who had high blood pressure or type 2 diabetes doubled their risk of premature death from heart disease or stroke if they slept less than six hours per night.

Can Lack Of Sleep Cause High Cholesterol

February 9, 2021// by Terry Cralle//

When people hear that they have high cholesterol, its a cause for concern and they may not be ready for a lifestyle change thats necessary. While many people think that the main reason behind their high cholesterol is bad diet, being overweight or drinking too much alcohol, they dont realize that lack of healthy sleep hygiene can be nearly as deadly.

In this article, well talk about the causes of high cholesterol and how it affects our health. Mainly, well talk about the link between high cholesterol and sleep, and how changes in your sleep routine can also fix your blood culture and improve the health of your heart.

Lets define the cholesterol as a whole properly. There are different types of cholesterol and each one of them has a different purpose. Cholesterol helps our body produce the necessary vitamin D which is used for treating infections and boosts our overall immunity. Additionally, certain hormones also benefit from different types of cholesterol.

In slang language, we often say that there is good and bad cholesterol. In a medical sense, good cholesterol is known as the high-density lipoprotein while low-density lipoprotein is known as the bad cholesterol.

HDL cholesterol can help eliminate the excess amount of other cholesterol. It delivers all the necessary material our body needs for healthy functioning and helps our body get rid of the bad materials.
