What Is The Connection Between Sleep Apnea And High Blood Pressure

Lower your blood pressure, and sleep better with one important mineral – Magnesium

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.

What Is Blood Pressure

Blood pressure is the force thats exerted by your blood on the walls of your arteries. Arteries are a type of blood vessel that carry oxygen-rich blood away from your heart, delivering it to the organs and tissues of your body.

Blood pressure is measured in millimeters of mercury . A blood pressure reading is made up of two numbers:

  • Systolic. This is the first number of your blood pressure reading. Its the pressure placed on your arteries when your heart beats.
  • Diastolic. This is the second number of your blood pressure reading. It measures the pressure on your arteries between heartbeats.

Now lets look at whats a normal blood pressure reading and whats considered high.

High blood pressure increases your risk of serious complications like heart attack, stroke, and chronic kidney disease. Thats why its important to take steps to keep your blood pressure within a healthy range.

Its known changing positions can impact your blood pressure reading. However, theres some disagreement about whether readings are higher or lower when youre lying down.

Several

  • 2017 study of 280 people with high blood pressure found that the average systolic and diastolic blood pressure readings were lower when measured while lying down than when measured in a sitting position. Its important to note that the participants in this study had their blood pressure taken after resting for 10 minutes, which may have influenced the readings.

The Truth About Sleep And Blood Pressure

Sharing is caring!

    Youve gone in for your routine physical examination, and youre told what millions of Americans are: you have high blood pressure But, like many Americans, you may not be aware of the truth behind the powerful connection between blood pressure spikes and the quality of your sleep.

In short, while quality, restorative sleep helps support our health, the opposite is also true: sleep disorders can affect our mind, bodies and even leave us more prone to depression.

    This week Im tackling the most common questions about high blood pressure and sleep, including is lack of sleep can cause high blood pressure why sleep apnea may play a role, and what might be behind a sudden spike of high blood pressure at night.

    Ill finish by giving you tips to lower your blood pressure naturally, no prescription required, and how to more easily fall asleep and fall back asleep if you wake up in the middle of the night using my Sleep Doctor PM formula. .

    You Rarely Go Outside

    Binging a new show on Netflix for days on end while quarantining inside your home should protect you from COVID-19, but it could increase your blood pressure or worsen existing hypertension, suggests a study in the Journal of American Heart Association. And why is this? It’s the lack of sunlight that’s boosting your blood pressure.

    In the observational study, researchers analyzed 46 million blood pressure readings from 342,000 patients in 2,200 dialysis clinics and found that exposure to UV sunlight was associated with lower systolic blood pressure. For decades, scientists have known of seasonal variation in blood pressure, but had linked it to factors such as air temperature and vitamin D, which is produced when sunlight hits the skin. This new study found that temperature played a role, but “half the seasonal variation in blood pressure is independent of temperature. It’s due to the UV alone,” said lead author Dr. Richard Weller of the University of Edinburgh in Scotland.

    How To Measure Your Blood Pressure At Home

    Pin on Tips for Healthy Heart

    If you need to measure your blood pressure at home, the following tips may be helpful in getting accurate readings:

    • Carefully choose your monitor. An automated, cuff-style monitor that fits around your upper arm is recommended by the American Heart Association. When choosing a monitor, check the:
    • Fit. Make sure that the cuff fits over your upper arm.
    • Validation. Check to see if the monitor is certified by a respected organization, like the Association for the Advancement of Medical Instrumentation or the British Hypertension Society. If its for an older adult, a child, or a pregnant woman, make sure the monitor is specifically validated for these groups.
    • Accuracy. Bring your monitor along with you to your next doctors visit. That way, you can make sure that its giving the same readings as your doctors equipment.
  • Take your blood pressure twice per day. Take the first reading in the morning, before eating or taking medications but not right after waking. Take your second reading in the evening. Aim to take the readings around the same time each day.
  • Prepare beforehand. Use the bathroom prior to taking your reading. Avoid caffeine, alcohol, and tobacco in the 30-minute period prior to taking a reading. Also avoid exercise or strenuous activity during this time.
  • Position properly. Try to use the same chair each time. Make sure your back is straight and supported by the back of the chair. Keep your feet flat on the floor.

    Blood Pressure Facts And Figures

    Healthy blood pressure ranges from 120/75 to 140/85. The higher is the systolic pressurethe pressure in the arteries when the heart is pumping. The lower the diastolic pressurethe pressure in the arteries when the heart is at rest, in between pumping.

    Blood pressure that is lower than these figures indicates that the blood vessel walls are too relaxed and blood isnt being efficiently pushed around the body, so nutrients that the blood carries, such as oxygen and iron, may not reach the tissues properly.

    Also the pulse rate tends to be fast, as the body tries to make up for the low pressure by pumping faster.

    • Fainting, feeling light headed or giddy, seeing spots or having tunnel vision on standing up
    • Sleep disturbances, night terrors, sudden waking with no obvious cause
    • Feelings of weakness and fatigue
    • Difficulty getting going in the morning
    • Low mood, sadness and hopelessness
    • Frequent headachesor migraines
    • Sensitivity to hot and cold
    • Dieting low protein intake

    Why Is High Blood Pressure At Night Dangerous

    Now, we all know high blood pressure could really put ourselves in big trouble, regardless of the time it occurs throughout the day.

    But why bother nighttime blood pressure?

    In fact, if the quality of your sleep is top-notch you dont really have to worry about this.

    But if not, there are three reasons you need to watch out for nighttime blood pressure closely.

  • Yikes! Sorry, this is to do with a hormone system, Renin-angiotensin System . I thought about it all the way there, and all the way back as to how to explain this easily. Here goes, RAS is responsible for regulating blood pressure. Nighttime is when RAS is operational at its peak. However, with a night of disturbed sleep, RAS doesnt perform well failing blood pressure regulation.
  • Aforementioned circadian rhythm coming into play again. A disturbed sleep cycle confuses the bodys natural sleep-activity cycle. Interrupted rhythm cant effectively lower down blood pressure when it should.
  • Do you know when do most heart attacks take place? Early in the morning. This is because out of control blood pressure through the night could sabotage those who are vulnerable.

    How Does Sleep Apnea Treatment Affect Blood Pressure

    There are a number of treatment options for OSA. Treatment not only improves sleep quality but could also help manage hypertension. The most common and effective treatment is called continuous positive airway pressure .

    CPAP treatment involves wearing a facemask attached to a machine that pumps air into the lungs at night. It works by preventing the airway from collapsing, which improves sleep quality in people affected by OSA. Studies investigating the effects of CPAP in patients with hypertension and OSA have shown that treatment with CPAP lowers blood pressure during the day and at night, especially in patients with severe OSA. CPAP also reduces catecholamine levels.

    Some patients have a hard time adjusting to the CPAP facemask at night. Consistent, proper use of CPAP is important in order to effectively manage OSA and hypertension. Mouthpieces are one alternative to CPAP and are designed to help maintain an open airway during sleep. Research is needed to determine if mouthpieces also lower blood pressure in people who experience high blood pressure and OSA. Certain surgical procedures are also done to treat OSA in selected patients.

    Losing weight either through diet and lifestyle changes or through weight-loss surgery is another approach to managing OSA that may also lower blood pressure.

    Blood Pressure Lying Down Vs Sitting

    How to sleep | Lower anxiety and blood pressure

    Many wonder why positioning makes such a difference in blood pressure readings. Lets take lying down vs. sitting as an example. Our heart is a pump, and it takes less work to pump blood to our brain when we are lying down. This is because our head is about the same level as our heart. However, when we are up, our head is a lot higher than our heart. This means the heart has to pump much harder to get blood to our brain, so as a result, blood pressure is higher.

    In most cases, blood pressure is taken while a person is sitting down with the arm dropping onto a table. While sometimes the middle point of the upper arm might, in fact, be parallel and in line with the position of the heart, the rest of the arm is not, so it should not be surprising that the measurement taking while laying down might be a little lower, since there is less gravity to counter.

    Possible Diseases From High Blood Pressure

    I hope the water hose tubes analogy helped you understand how problematic hypertension could be. Ill list some possible malfunctions of the body to do with high blood pressure.

    • Heart attack: This is an umbrella term that includes so many types of heart diseases but let me put it as basically as I can. Generally, a heart attack means ACUTE heart failure due largely to blockage of blood flow to the heart
    • Heart failure: Unlike Heart heart attack, it refers to the CHRONIC failing of the heart. Mostly, medications could help prevent symptoms.
    • Stroke: When blood flow to the brain is interrupted stroke is very much in the cards. Depending on which part of the brain is affected the symptoms of the disease hugely vary.
    • Dementia: Some stroke could give rise to dementia. Amongst others, Vascular dementia the one that mainly comes with a stroke. Understanding the types of dementia could help you comprehend more easily.

    How To Lower Blood Pressure While Sleeping

    Believe me, there is a slew of blood pressure-lowering techniques out in the wild. Its like there are a million ways to lose weight .

    I am not going to explain every single thing here, but Ill let out some of the good methods that I EYE-WITNESSED the effectiveness in my patients.

    • Quit smoking: The damn worst thing in the world! When you smoke it constricts the blood vessels and damages their walls in the long run. By stopping smoking you can somehow lower down your blood pressure even in a day! See my other blog post about 5 reasons not to smoke.
    • Eat less junk food: This food carries a ton of sodium which causes water retention in your body. Its not really helping with your high blood pressure.
    • Take potassium: I recommend that you eat potassium tablets unless can eat bananas like a monkey all day long. Potassium is excellent at getting rid of sodium out of your body. A lot of my patients have benefited from this regime. Why dont you try?
    • Workout and lose weight: Being overweight or obese could be pretty critical as it increases the resistance to blood flow, which means your heart should work harder to pump blood. Yes, losing weight isnt easy but it could actually save you from lots of nasty health issues.

    You Do Things That Give You Incorrect Numbers

    Blood pressure readings can vary widely, which is why it’s recommended that you take two or more measurements on two or more occasions and average them to get the most accurate numbers, suggests Lawrence Fine, MD, DrPH, at the National Heart, Lung, and Blood Institute of the NIH. To get the most useful measurement, be sure you don’t make these mistakes that can easily cause an artificially high blood pressure reading:

    • You’re nervous about going to see a doctor. These natural jitters about doctor appointments can actually raise your BP. And it’s one reason taking a blood pressure reading in the comfort of your stress-free home may give you a more accurate result.
    • You are slouching or sitting in a sofa. Bad posture during a test can skew results.
    • You cross your legs, which can squeeze the large veins in your legs and raise blood pressure.
    • You’re making conversation with the nurse who is checking your blood pressure. Talking can actually boost your pressure.
    • You had a double shot of espresso this morning. Caffeine jolts up blood pressure, too!

    Blood Pressure At Night: What Is The Effect

    Dr. Goel explains, “Cardiovascular and respiratory parameters of the body change during sleep, wakefulness and physical activity. There are signals sent to the brainstem which communicate these changes to the peripheral baroreceptors which in turn relate the information to the neurotransmitters. When the blood pressure is elevated, the sympathetic outflow decreases and vice versa. During NREM that is during sleep parasympathetic drive increases with an associated reduction in sympathetic activity. The decline in sympathetic activity causes a dip in pressure, which is a healthy response.”

    “Non-dipping, rising or extreme dipping is associated with an elevated cardiovascular risk. Many times autonomic instability with fluctuations in blood pressure and respiratory rate have been reported during sleep,” Dr. Goel adds.

    Anyone with uncontrolled hypertension should get 24 hours ambulatory blood pressure measurement done so that the medicines can be tailored to keep a good steady 24 hours of pressure control. Also, it will help determine the timing of the pressure tablets and their frequency. Lifestyle modification will help in maintaining healthy blood pressure numbers. Some of these are-

    • Regular exercises
    • Efforts to reduce stress
    • Less intake of food substances with high sodium content

    You Don’t Drink Enough Water

    While drinking water has been shown to boost metabolism and slightly raise blood pressure, being dehydrated can also raise blood pressure. A study in the journal Sports Medicine found that acute body water loss due to sweating can disrupt proper function of the lining of blood vessels, the endothelium, impairing blood pressure regulation. Even mild dehydration can thicken blood and impede blood flow and raise bp, the study found.
