How Your Sleep Habits May Be Damaging Your Heart

Posted: 12/10/10 08:51 AM ET

If someone said to you that your lifetime risk of a heart attack was close to 100 percent, you'd probably want to do everything you could to either prevent that fate or delay it by as long as possible, right?

Heart attacks continue to be the number-one killer of Americans; 1.5 million heart attacks occur in the United States each year, with 500,000 deaths. Costs related to heart attack exceed $60 billion per year.

Most of us are aware of the ways in which we can help keep our hearts healthy:

  • Eating a sensible, balanced diet high in healthy fats and low in saturated fat.

  • Keeping our cholesterol and blood pressure under control.

  • Maintaining a regular exercise routine that gets our heart pumping faster.

  • Managing stress.


But what about sleep? How does that factor in?

Turns out that sleep factors in big time: a new study shows that poor sleep may worsen heart health by increasing inflammation. Chronic inflammation has gained a lot of attention in recent years due to the associations found between this bodily process and an array of illnesses and disease. While inflammation is a normal physiological process and part of our immune system, when it runs amok it can wreak havoc on our cells and tissues. This explains why inflammation can play a major role in heart health, as it can lead to restricted blood flow and increase the risk of heart attack and stroke.

This recent study found that regular bouts of insomnia and poor sleep quality may increase inflammation throughout the body, which may be further aggravated by high cholesterol, resulting in heart complications. The specifics:

  • After surveying 525 participants on their sleep habits, researchers from Emory University measured their levels of certain inflammatory hormones, including the famous C-reactive protein that's used as a biomarker for inflammation.

  • They found that individuals who regularly got the least sleep were significantly more likely to have high levels of the hormones and, consequently, inflammation.

  • In fact, adults who slept for six or fewer hours had higher levels of all three inflammatory markers that the researchers measured.

  • The researchers at Emory also noticed that men and women with poor sleep quality had higher blood pressures.


There was something else that the researchers discovered to their surprise: men -- not women -- who experienced poor sleep quality had less flexible arteries. This condition also contributes to hypertension and puts more stress on the heart.

The reason for this could be due to certain hormones or other variables going on in women that help explain the discrepancy. This doesn't mean women can get away with poor sleep. It just means that we need to study gender differences when it comes to health and their separate risk profiles.

Fibrinogen, one of the other markers observed in this study, forms a fibrous mesh that slows blood flow, thus increasing blood pressure and potentially causing hypertension. This fibrous mesh quickens the time it takes for your blood to clot, which can cause a stroke or heart attack.

So it goes without saying that we all need to keep sleep on our list of priorities for keeping our hearts healthy and strong.

Bottom line: Rest up to keep your heart up and running. You may feel like a ticking time bomb as you juggle too many to-dos and run around like mad addressing your commitments and obligations. But that ticking time bomb can be real if you're simultaneously throwing sleep out the window. Add more minutes to your life just by adding more quality sleep minutes to your time in bed.

It really could be as easy as that.

Sweet dreams,

Agreed. Sleep, and perhaps most importantly, quiet, still rest, the body needs to re-charge, re-build and regenerate. Our frenzied, modern lifestyles borrow on our life-force more heavily than we really recognize. This article helps to bring us back to reason and balance. Thank you Michael for the thoughtful comments. Mitchell Rabin

Since I was a teenager, I have always had problems sleeping. Physical activity doesn't do it for me, I can chop wood all day or work out hard and still have problems sleeping at night. I toss and turn all night, wake up multiple times and have a problem getting back to sleep, if I can get back to sleep. I recently started taking sleep aid pills and I know there are probably side effects of that, but I have been sleeping all night long and today even slept in until 10 and that NEVER happens with me. It felt great. Now if I wake up in the night, I fall back asleep right away. I can't remember the last time I had deep sleep like this.

Do some research on melatonin I used to work 3rd shift and it helped me get a restful sleep for over 5 years. Its produced by the body but the body needs darkness to activate it. Check it out it may be safer?

thanks for the suggestion. I did try that and it didn't work for me. It helped a little in falling asleep, but I didn't stay asleep all night and still was restless. But I did try it first.

Guess what else? There is almost no real study on what causes insomnia other than anxiety. I have been insomniac my whole life, and yes I have done the cognitive and behavior therapy, the sleep hygiene, etc. etc. etc. I still don't get enough sleep and it does terrible things to me. Can I find help? Ha!

Sleep apnia runs in my family and so do heart attacks.  If I slept on my back I'd snore. But I don't so I don't. I'm keeping my fingers crossed that 7-8 hours a night peacefully face-down will translate into avoiding 'the Big One'.

What if some one told you that you had pretty close to a 100% chance of dying of a heart attack.

Well one thing for sure is that we will all die. Most will die of heart attacks. None will survive much past 100. So my remedy, and I am 70, is stay away from your doctor. He is in the sick business. If you get something serious he is not going to cure you. Most things will pass with time if you see him or you don't.

I had by pass surgury almost 20 years ago. I did not need the surgury but my doctor, i think he had ordered a new Mercedes and wanted to pay for it faster talked me into it. I have not seen a doctor for anything in the past 15 years. I feel healthier, less stressed out and less worried about every little ache and pain than I ever did.

Want to live a long life? Stay out of hospitals and doctor's offices. They are more likely to kill you than save you. And don't ever forget. They bury their mistakes. a second thing to never forget is that they are in it for the money. So they will medicate you to the high heavens, they will convince you that you have illnesses and deseases that you do not have. In other words when you walk into their office, if you are not carefu,l you will die in his care.,

Herring! This is inexcusable, very poor advice. It is unfair to generalize that all physicians are "in it" for the "gold" or for another "Benz," You insult some of my very best friends who didn't need the money, and continue not to need the money. But even if "doctors" are in "it" for the money...this is a noble career and most of us HAVE to work. Your suggestion is that nobody become a doctor? Your stereotypes and generalizations do not help our already ailing medical system and community. I'm sorry YOU CHOSE a bad physician. But I frankly feel as I've had many a physician that saved my life. And while indeed most illnesses will pass what about the ones that won't? Should my best friend who has been cancer free now because of an excellent doctor have not gone to that doctor. He'd be dead right now and not a 40 something year old healthy male (prostate). And should another one of my best friends not gone to an oncologist because of his brain tumor? If you want to live long and you have a healthy body then live a healthy lifestyle. Even better if you're blessed with health. But I know folks that have had problems since they were born and need a doctor just to continue to live. What about dialysis? What about diabetes? Every single disease/illness I mention here are ALL affected and effected by how much sleep a person has. BAD ADVICE!

Ramblin Rose, I'm glad you bring up diabetes. My husband has Type l. Yes, he needs insulin to survive. But he also needs to manage his diet, exercise, sleep and emotions to survive. Doctors are fairly useless when it comes to lifestyle.

Right on dude! Before my mom died she was in and out of the hospital. Always she was there because of either a prescription drug reaction or it was because of no exercise and poor diet.
A lot of people think that doctors hold the key to health. Truth is, each of us personally hold the key to health. Even when we're victims of accidents or genetic disorders we play a MAJOR role in healing.

I recently made a lifestyle change that has improved the quality of my sleep and has made me feel more coherent and well-rested in the morning. I, now, stop abusing caffeine 24/7. I only abuse it for the first eight hours of the day and then switch to water for the evening hours.

I think this has had a positive impact on my getting to sleep as well as the quality of sleep during the night because my brain is not all wired-up with the stimulant. If you abuse caffeine like I did (drinking diet soda all day), try cutting it out of your diet for the evening hours (or the hours before your regular sleep) to see if that helps.

I do pretty much the same thing coffee in the morning, then water all day and one or two good beers everyday. It helps cutting the caffiene out early in the day. Never drink soda havent for about 5 or 6 years now. I've lost about 10% on the body fat index.

Sleep is important, but maybe the doctor should watch this video about the cholesterol myth and how atherosclerosis and thrombosis really come into existence; http://www.cutthecarb.com/prevention-and-regression-atherosclerosis-and-thrombosis/

How about this? NOT running to the doctor at the first sign of trouble? How about using common sense? If you're overweight, exercise and change your diet. If you're sleep deprived, try Tai Chi or yoga. If you're really sleep deprived, rotate your mattress and do good, old-fashioned manual labor til you are exhausted enough to sleep. How about recommending some cheap or free remedies? not all of us have money growing on trees in the yard. Or have money in the bank.

As someone who has suffered from chronic insomnia since childhood, I feel compelled to inform you that 'old fashioned manual labor' does not solve the problem. Neither does money in the bank.

I'm a lifelong insomniac, too. Not every method works every time for me, but I keep on trying. I firmly believe that the layout of our sleeping arrangements when we are young can influence our whole life of sleep. As a toddler, I slept in a room of antique furniture, on the top floor, alone. I think I still can't shake being scared. How do we rewire ourselves? I'd like to think that we try everything, and know that the answer lies within us, not on the outside. As for the money comment, it's a stressor for most people. When I worry about our property taxes increasing, or our daughter's hospital bills, I can't sleep, no matter what I do.

Bravo!! MY BEST FRIEND DIED OF SLEEP APNEA!! That's right 9/17/2010. His mask fell off. Simple as that. He didn't get a trigger to inhale and he passed away. Gone in a flash. The 'old fashioned manual labor' suggestion is insulting. A little like asking somebody to throw a thimble full of water on a burning house! I'll miss you JD...forever, may you now get some real sleep!

For some of us, there is no "exhausted enough to sleep." You are correct that excercise is important, but you are dead wrong to think that just because your insomnia is easily dealt with, everyone's will be just as easy. Be grateful for a blessing.

I didn't say I was successful every night. I have even gone so far to rearrange bedroom furniture, move across the hall to another bedroom, buy new pillows, anything. It is an ongoing process. And sometimes things work for a while, but what do you do when they stop? Search for more answers, no matter where. I think we have to rewire ourselves, and redo everything we have learned that keeps us up at night. It seems crazy to think we can't beat this somehow.

I go to sleep around 10:30 or 11PM and awake around 6:30-7AM but I wake up 3-4 times a night, tossing and turning and sometimes having a hot flash, and it takes a few minutes to get back to sleep So is this interrupted sleep as damaging as little sleep?

Argh. Except, except...except people who can't sleep, um, they can't sleep. It's not like there are all these great options out there for dealing with that. Yes you can go see a doctor. That will run you about $80 if it's a GP, unless you've met your deductible for the year. Eight dollars probably sounds like nothing if you are an MD, but for lots of families right now, an extra $80 is nothing to sneeze at. Then, when you get there, the doc will tell you to reduce stress, exercise more, get the TV out of the bedroom, and you'll likely get a script for Ambien or something similar that, something that comes with it's own set of problems and isn't free. And that's if the doc has time to tell you that, which, if it's your GP--well maybe, maybe not.

Right now, the American workplace--if you are 'lucky' enough to be a part of it--comes with relentless productivity demands and zero security. Many parents are working three or four jobs between them and still not making ends meet. If one person or both are out of work, it's even worse.

Of course people can't sleep. As for heart attacks, America is kind of in the middle of one, right now. The American Dream right now is a recipe for a heart attack.

But there is one drug that seems to be effective protection in many cases: Money.

Lots and lots of money.

You are a voice of common sense (and I guess it is what "coaching" is all about by the way): more than often stress causes bad quality sleep, damages the heart and is the real killer.
05:48 PM on 12/11/2010
I can't believe Ms. Grundy actually sleeps as little as the suggestion just by the sheer lack of sensitivity she tosses off this sort of "common sense" you don't "coach" a person out of sleep apnea. beautiful planet I'm sorry but I simply think you haven't really thought out your comment. You treat it as if it is a choice..."I'll choose to get healthy and sleep better" those who have chronic insomnia are tortured by it. Turn themselves inside out trying to "get better" and not die in their sleep! My best friend died of sleep apnea but can I point out he did not work at all?! Well, he built me a computer but it wasn't a stressful job! Please take this condition seriously. Would you ask a diabetic to blow off their insulin shot? Tell a heart patient to avoid nitro-glycerin. Not about coaching...
