Sleep Apnea And High Blood Pressure
Obstructive sleep apnea occurs when the soft tissues at the back of the throat relax and block the airway during sleep. Researchers think these pauses in nighttime oxygenation may activate the bodys fight-or-flight mechanism, which raises the blood pressure. Interestingly, however, the use of continuous positive airway pressure devices to maintain nighttime breathing do not necessarily improve hypertension in people with both and high blood pressure. Nonetheless, if you have both OSA and hypertension you should adhere to the treatment plan for improving your sleep apnea, as this may have a positive effect on your blood pressure.
How Sleep Impacts Blood Pressure
High-quality sleep is essential to good health, and thats especially true when it comes to achieving and maintaining healthy blood pressure readings.
A 24-hour hypertension study published in the American Journal of Hypertension discovered a strong link between sleep deprivation and high blood pressure. The study included 36 subjects consisting of 20 men and 16 women. Researchers measured participants blood pressure readings, both on days when the subjects had a full nights sleep consisting of 8 hours of undisturbed rest between 11 pm and 7 am and on sleep-deprived days when participants were only permitted to sleep undisturbed between 3 am and 7 am.
The study authors found that average blood pressure readings and heart rates were notably higher for all participants on sleep-deprivation days. Researchers also revealed that blood pressure and heart rate readings rose significantly in the morning immediately following a sleep-insufficient night, a finding that could explain why heart attacks and strokes are most common in the early morning hours.
Cardiovascular events are also more likely to occur on Mondays than any other day. Many people tend to stay up late on the weekend, which disrupts the bodys sleep schedule and often leads to sleep deprivation on Sunday nights.
I Sleep And The Heart
The process of sleep is made up of the following two primary stages:
When you first fall asleep you are in the non-REM stage. The non-REM stage of sleep is a time when your heart does not have to work so hard. About 80% of a full nightâs sleep is spent in this stage. During non-REM sleep, your heart rate, breathing and blood pressure all drop to levels below those that occur while you are awake.
REM is the stage of sleep when you have most of your dreams. It is only about 20% of your total sleep time. Your blood pressure and heart rate can go up and down during this stage. If you have a nightmare that wakes you up, you may find that your heart is racing.
When you wake up in the morning, your blood pressure and heart rate both go back up. It is time for you to be active again, and your heart has to get ready for a long day of work.

Ultimately There Are Lots Of Reasons Your Heart May Be Racing
Sometimes its nothing major. Other times, especially when accompanied by symptoms like feeling lightheaded or dizzy, having chest pain, or feeling fatigue, it can be a sign that you should see a doctor. It doesnt matter how healthy you are or how healthy you think you are, Dr. Doshi says. If your heart doesnt feel right for you, its worth getting a checkup.
Sleep And Blood Pressure
During normal, healthy sleep, blood pressure drops by around 10-20%. This is known as nocturnal dipping, and research highlights its role in cardiovascular health.
Poor sleep, whether from a lack of sleep or sleep disruptions, is associated with non-dipping, meaning that a persons blood pressure doesnt go down at night. Studies have found that elevated nighttime blood pressure is tied to overall hypertension .
In fact, nocturnal blood pressure has been found to be even more predictive of heart problems than high blood pressure during the day. Non-dipping has been tied to an increased risk of stroke and heart attack. Its also been linked to kidney problems and reduced blood flow to the brain.
Raised daytime blood pressure has been identified as a consequence of sleep deprivation in multiple studies, but it doesnt affect all people equally. The link between lack of sleep and high blood pressure is highest in middle-aged adults. People who work long hours in high-stress jobs and people with other risk factors for hypertension are more likely to have raised blood pressure after chronic poor sleep.

Is It True That Sleep Deprivation Can Cause High Blood Pressure
Possibly. It’s thought that sleeping fewer than six hours a night could be linked to increased blood pressure.
People who sleep five hours or less a night may be at higher risk of developing high blood pressure or worsening already high blood pressure. There’s also an increased risk of high blood pressure for people who sleep between five and six hours a night.
It’s thought that sleep helps your blood regulate stress hormones and helps your nervous system remain healthy. Over time, a lack of sleep could hurt your body’s ability to regulate stress hormones, leading to high blood pressure.
Sleeping seven to eight hours a night may play a role in the treatment and prevention of high blood pressure. Talk to your doctor for tips on getting better sleep, especially if you have high blood pressure.
One possible, treatable cause of your lack of sleep contributing to high blood pressure is obstructive sleep apneaa sleep disorder in which you repeatedly stop and start breathing during sleep. Talk with your doctor if you feel tired even after a full night’s sleep, especially if you snore. Obstructive sleep apnea may be the cause, and it can increase your risk of high blood pressure, as well as heart problems and other health issues.
What Does Sleep Have To Do With High Blood Pressure
Your blood pressure directly responds to sleep loss along with a whole host of negative side effects. A 2010 study conducted amongst 538 middle-aged adults found that sleep deprivation was a reliable predictor of increased blood pressure levels. The results remained consistent even after being adjusted for age, race, sex, and presence of high blood pressure medication. In these cases, both shortened sleep duration and poor sleep quality contributed to the increase in blood pressure readings.
In part, sleep deprivations effects on the mental and emotional state shed light onto the forces at work. Without enough sleep, the brain becomes more sensitive to negative thoughts and feelings, which causes an increase in stress hormones like cortisol that naturally cause a rise in blood pressure.

Lack Of Sleep And Its Effect On Blood Sugar Levels
May 15, 2017 by Sound Sleep Health
More than 29 million Americans suffer from diabetes, according to the Centers for Disease Control and Prevention, with millions more falling into the pre-diabetes range. Keeping blood glucose levels under control is essential to good health, both for people with diabetes and those who do not have the disease. Although most people know that dietary choices and exercise affect blood sugar levels, many do not realize that sleep can also have a dramatic effect on glycemic control. Failing to get enough sleep or getting poor quality sleep can have serious effects on your blood sugar. This is unhealthy for all individuals but particularly dangerous for those with diabetes or prediabetes.

Can Lack Of Sleep Cause Heart Palpitations
Heart palpitations are skipped beats, extra beats, or pauses in beats. It can also be fluttering in the chest and a flip-flopping sensation. It is caused by the disruption of the normal electrical activity or function of your heart. They are a common occurrence in those who suffer from anxiety, high levels of stress, those who lack sleep, have too much caffeine or too much exercise. It can also be a sign of heart disease or some other disease the can affect the heart or other parts of the body.
Since a lot of heart problems can be caused by stress and anxiety, it is certainly possible that sleep deprivation can cause heart palpitations or heart racing. The less you sleep, the more anxious and nervy you get, leading to these palpitations. Also, if you suffer from atrial fibrillation, it causes palpitations. Lacking sleep can also affect this condition, making it worse.
What Health Conditions Are Linked To A Lack Of Sleep
Adults who sleep less than 7 hours each night are more likely to say they have had health problems, including heart attack, asthma, and depression.3 Some of these health problems raise the risk for heart disease, heart attack, and stroke. These health problems include:
- High blood pressure. During normal sleep, your blood pressure goes down. Having sleep problems means your blood pressure stays higher for a longer period of time.4 High blood pressure is one of the leading risks for heart disease and stroke. About 75 million Americans1 in 3 adultshave high blood pressure.5
- Type 2 diabetes. Diabetes is a disease that causes sugar to build up in your blood, a condition that can damage your blood vessels. Some studies show that getting enough good sleep may help people improve blood sugar control.6
- Obesity. Lack of sleep can lead to unhealthy weight gain. This is especially true for children and adolescents, who need more sleep than adults. Not getting enough sleep may affect a part of the brain that controls hunger.6

Effect Of Continuous Positive Airway Pressure On Bp
If OSA contributes to hypertension development or progression, then effective OSA treatment with continuous positive airway pressure should lower BP. However, reports are conflicting. This lack of a consistent treatment effect may be related to multiple variables, including differences in study design, type and size of cohorts, degree of CPAP compliance, treatment duration, and accuracy of BP assessments.
Recently, four metaanalyses of randomized controlled trials on CPAP use have been published . Bazzano et al analyzed 16 randomized clinical trials published between 1980 and 2006, representing 818 participants, that compared participants treated with CPAP with control subjects, that had a minimum treatment duration of 2 weeks, and that reported BP changes during the intervention and control period. Mean net change in systolic BP for participants treated with CPAP vs control subjects was 2.46 mm Hg mean net change in diastolic BP, 1.83 mm Hg and mean net change in mean arterial pressure, 2.22 mm Hg . The authors concluded that their analysis provided evidence that effective CPAP treatment reduces BP.
A Consistent Lack Of Sleep Can Potentially Cause Heart Disease
- Research has found that a lack of sleep is associated with high blood pressure and heart disease.
- Most adults should get about 7 to 9 hours of sleep each night, yet about one-third of Americans do not.
- Sleep apnea and insomnia two conditions that result in lack of sleep are also major risk factors for heart disease.

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.
