  • The 12 Best Ways to Fix Atrial Fibrillation with Sleep

    The 12 Best Ways to Fix Atrial Fibrillation with Sleep
    2021/12/11
    The 12 Best Ways to Fix Atrial Fibrillation with Sleep Whenever people try to get healthier, and no matter what the underlying reason for that effort, they almost always start with diet and exercise. Those are two very important factors, but without addressing a third factor—sleep—they are almost assuredly doomed to fail in their efforts to eat better and exercise more. In this article, I'm going to give you my 11 best ways to fix atrial fibrillation with sleep. Most of Us Are Really Bad at Sleep Let's face it, most of us are really bad at sleeping. And as a global community, it would appear, we’re actually getting worse at it, even as the science that demonstrates its importance to our lives has gotten more and more compelling. The World Health Organization has raised the possibility that sleep problems are an emerging global epidemic. In the United States, 70 percent of adults report insufficient sleep at least once a month, and 11 percent report insufficient sleep every night. For a while, it did seem like we were getting the message about the importance of sleep to our health. After a century of consistently diminishing sleep, researchers who study the way we slumber noticed something promising. From 2004 to 2012, the number of people who were getting less than six hours of sleep each night finally started to level out. Maybe, some thought, we were finally getting the message. Or maybe, others argued, we’d simple hit rock bottom. Either way, it seemed, we could finally start working to move the needle in the other direction. But when demographic sociologist Connor Sheehan and his collaborators dove into the subject in the late 2010s, they were dismayed by what they found. Yes, there had been a leveling out starting in 2004, but between 2013 and 2017 there was a significant shift. Far more people were reporting far less sleep. We hadn’t hit rock bottom after all. What changed? Among the most important factors are the devices we increasingly carry in our pockets, purses, and person. Closely coinciding with the quickly falling rate of adequate sleep was the rapidly rising rate of smartphone ownership, which went from 35 percent in 2011 to 77 percent in 2016. “Americans now spend more time looking at a screen,” Sheenan and his collaborators wrote, “and, due to the mobile nature of these devices, technology has increasingly entered the bedroom.” This isn’t just happening in the United States. More than 5 billion people around the world now have mobile devices, and more than half of those devices are a smartphone. Leading the way in the adoption of tiny, glowing screens is South Korea, where 95 percent of adults have a smartphone and where, perhaps not coincidentally, adults get nearly 40 minutes less sleep each night, on average, than their global counterparts. Because smartphones may be a cause of poor sleep, and also because these devices are increasingly equipped to detect the health consequences that result from poor sleep, it should come as no surprise atrial fibrillation diagnoses have skyrocketed in Korea in recent years. Why is Sleep so Critical for Atrial Fibrillation? The impact of poor sleep on AFib has been well documented. Even small interruptions of sleep quality and duration can increase the risk of atrial fibrillation by 18 percent, and people who experience insomnia are 30 to 40 percent more likely to develop atrial fibrillation. People who do not reach deep levels of sleep—the sort of sleep that is key to recovery—have an 18 percent increased risk of atrial fibrillation, and it worsens each time they wake up at night. It’s even worse for people with sleep disorders such as sleep apnea; they have a 200 to 400 percent increased risk of AFib over individuals without a sleep breathing disorder. And the problem is compounded once AFib actually develops; the presence of an abnormal rhythm can increase the risk of poor sleep quality, or short sleep, by three to four times.

  • The 11 Worst Medications For Causing Atrial Fibrillation

    The 11 Worst Medications For Causing Atrial Fibrillation
    2021/11/28
    The 11 Worst Medications Causing Atrial Fibrillation Could one of your medications actually be causing your AFib? Over the years I've seen a number of patients either significantly decrease their AFib episodes or even put their AFib into remission for a few years just by getting off an AFib causing medication. For those who needed a particular medication, catheter ablation was very helpful in eliminating the AFib so that they could continue to take their necessary medication. Below are my 11 worst medications causing atrial fibrillation. 1. Diuretics With the exception of spironolactone (Aldactone) and triamterene, diuretics can be problematic for atrial fibrillation patients. The reason is that most diuretics are well-known to cause mineral depletion in the body. Depletion of those key minerals, especially potassium and magnesium, is often enough to trigger atrial fibrillation. 2. NSAIDs Non-steroid anti-inflammatory drugs, or NSAIDs, can also induce AFib. NSAIDs are relatively common drugs like ibuprofen and naproxen that are often used to fight pain. NSAIDs are particularly troublesome for AFib patients because they also increase the risk of heart and kidney failure. For those who are also on a blood thinner, NSAIDs increase the risk of an emergency room visit for a life-threatening gastrointestinal bleed. 3. Proton Pump Inhibitors Proton pump inhibitors, which suppress stomach acid, can also atrial fibrillation by blocking magnesium absorption or possibly by changing a person’s gut microbiome. These drugs include omeprazole, lansoprazole and pantoprazole, which are often sold under the brand names Prilosec, Prevacid, and Nexium, respectively. 4. Steroids Steroids, like prednisone and Solu-medrol, can cause atrial fibrillation, too, by raising blood glucose levels to very high levels and increasing blood pressure through fluid retention and weight gain. Over my career, I've even seen many cases of steroid injections triggering AFib. 5. Any Stimulant Cardiac stimulant medications, like albuterol inhalers or theophylline for asthma, have long been associated with AFib. Even over-the-counter decongestants such as pseudoephedrine, which is sold as Sudafed, or medications for attention deficit hyperactivity disorder can trigger an AFib attack. The bottom line is that anything that revs up the cardiovascular system has a risk of causing AFib. 6. Digoxin, Diltiazem, Verapamil, and Beta-Blockers Perhaps a bit counterintuitively, some if the classic drugs used to treat abnormal heart rhythms such as digoxin, calcium-channel blockers such as verapamil and diltiazem, and beta-blockers have all been associated with an increased risk of AFib. While the exact mechanisms whereby these drugs may increase the AFib risk aren't entirely clear, plenty of cases have been documented in the medical literature. We’ve even seen beta-blockers, which are often used to treat AFib, linked to AFib episodes due to associated weight gain, particularly with women. 7. Fish Oil As many readers know, there is prescription-strength fish oil, like Lovaza, as well as the over-the-counter fish oil. Prescription-strength fish oil is used to treat high triglycerides whereas the over-the-counter version is used to treat a myriad of complaints. Regardless of which form it is, fish oil has now been implicated as a potential cause of AFib. If fish oil has been particularly helpful for you, try keeping the dose under 1 gram per day to minimize the risk of AFib. Or, alternatively, you can do what I've done and go back to eating wild-caught fish high in omega 3s instead of taking a supplement. Interestingly, since stopping fish oil for myself, I've noticed a lot fewer palpitations. 8. Antiarrhythmics like Amiodarone, Flecainide, and Propafenone Another surprise to many readers is that the antiarrhythmic drugs, the ones that are supposed to prevent AFib, have been linked to AFib. For example, amiodarone is well-known to cause hyperthyroidism which ca...

  • The 7 Most Important AFib Triggers to Avoid

    The 7 Most Important AFib Triggers to Avoid
    2021/11/20
    The 7 Most Important AFib Triggers to Avoid A new study was just published identifying the most important AFib triggers to avoid. Avoiding AFib triggers is incredibly important for AFib patients and something we covered in our best-selling book, The AFib Cure. In this article, I discuss the 7 most important AFib triggers to avoid based on published medical studies and my 30 years of experience caring for AFib patients. What are your AFib triggers? While most of my patients can identify at least one specific AFib trigger, many cannot. For some of my patients, AFib attacks are 100% random events so they don't have any clearly identifiable triggers. If you can identify one or more AFib triggers, then avoiding these triggers can be a very effective way of putting your AFib into remission naturally. 1. Alcohol At the top of every published study of AFib triggers is alcohol. Sadly, there is no safe dose of alcohol for AFib patients. And that shouldn’t come as a big surprise as any emergency room doctor can share many stories of high school or college students who have presented with AFib after binge drinking. 2. Exercise Exercise is the most natural way in the world to shift our hearts into a higher gear, so it’s no shock that, if your heart is already prone to beating erratically, a quick burst of exercise could push it over the edge. But avoiding exercise is simply not an option as not exercising at all dramatically increases your risk of AFib and an early death. For those suffering from exercise-induced AFib, many of my patients have found that simply decreasing the intensity or duration of their exercise can help tremendously. For others, they can still exercise vigorously without AFib provided they have slept well, are well hydrated, and have their electrolytes in check. When nothing prevents exercise-induced AFib, it is time to consider an ablation. Indeed, I have countless patients, including elite world-class athletes, who have all successfully returned to high levels of exercise free of AFib with an ablation procedure. 3. Dehydration/Electrolyte Depletion It always amazes me how so many of my patients' AFib attacks come from when they aren't drinking enough water. Indeed, many of my patients fail to realize that their fatigue, dry skin, headaches, muscle cramps, urinary tract infections, constipation, dizziness, brain fog, or their AFib all happen because they aren't drinking enough water. And proper hydration is especially important for AFib patients before exercising. In addition to adequate hydration, optimization of electrolytes is also necessary to keep the heart beating right in sinus rhythm. For example, potassium and magnesium depletion are well documented AFib triggers in the medical literature. Fortunately, both can easily be replenished with a diet high in vegetables, fruit, nuts, seeds, legumes, etc. Indeed, many of my patients report that magnesium supplementation has been essential to keeping their AFib in remission. When it comes to optimizing your electrolytes, please don't turn to sports drinks. Sport drinks are nothing more than sugar water or artificial sweetener water with chemical dyes and a trace amount of electrolytes. If your goal is to optimize for sinus rhythm and longevity, get all the electrolytes your body needs from natural food sources like vegetables, fruit, nuts, seeds, legumes, etc. 4. Poor Sleep A bad night of sleep is another big AFib trigger. Bad sleep could be from sleep deprivation or sleep apnea. Indeed, studies show that a bad night of sleep increases your risk of AFib 3x the next day and sleep apnea quadruples your AFib risk. Make restorative sleep a priority! While sleeping on your left side is often uncomfortable for AFib patients, a recent study did not show an increased risk. So, while you may feel more palpitations when sleeping on the left side from gravity pulling your heart toward your chest wall, it probably won't cause an AFib attack. 5.

  • Is Caloric Density the Secret to Eating as Much as You Want without Gaining Weight?

    Is Caloric Density the Secret to Eating as Much as You Want without Gaining Weight?
    2021/11/14
    Is Caloric Density the Secret to Eating as Much as You Want without Gaining Weight? By Kate Clemens with John Day Is there a way to never feel hungry again and not gain weight? One answer is to mostly eat only those foods with the absolute lowest caloric density. In other words, a low caloric density means you want the most food you can get on your plate with the least amount of calories. And in this article, we'll teach you everything you need to know about the low caloric density eating approach. Dr. Day's Experience with Low Caloric Density Eating Focussing primarily on foods with the lowest caloric density has been something Dr. Day has done for the last 10 years to maintain his 30-pound weight loss. For him, pilling up his plate high with food not only fills his belly but also psychologically convinces his brain that he is full. As vegetables have the lowest caloric density this is what fills up most of his plate. And because oils have the highest caloric density, he avoids them whenever possible. For example, when making a salad he puts berries, beans, nuts, and seeds on his salad, rather than salad dressing, because berries, beans, nuts, and seeds have a much lower caloric density (see chart). In general, Dr. Day keeps his caloric density below 780 calories per pound unless he is eating nuts, seeds, or some very dark chocolate (>70% cacao and usually stevia-sweetened). Of note, his wild salmon measures in at about 780 calories per pound. On rare occasions, he will just put a small taste of salad dressing on a fork (he never puts the dressing on the salad) if berries, beans, nuts, or seeds are not available to flavor his salad. Caloric Density Works Caloric density is a straightforward approach to weight management that works. The idea is to increase the amount of food on your plate while decreasing your total caloric intake. You do this by paying attention to the calories per pound in the food you choose to eat. The best part of it is that you eat for satiety and optimize the amount of nutrients you take in at each meal. 5 Key Findings from Weight Loss and Caloric Density Research What does research tell us about the caloric density eating approach? Below is a summary of the best studies: 1. People can eat freely foods that are about 300 calories per pound or less and not gain weight. 2. People can consume relatively large portions of foods that are between 400 and 800 calories per pound and still lose or maintain their weight depending on their individual activity levels and metabolism. 3. Foods with a calorie density of 800-1,800 should be limited as these can contribute to weight gain and interfere with efforts to lose weight. 4. Foods over 1,800 calories per pound should be extremely limited as these foods can very easily contribute to weight gain and obesity and can also greatly interfere with efforts to lose weight. 5. In 2007, the American Cancer Institute and the World Cancer Research Fund published a report which recommended the average calorie density of the American diet be lowered to 567 calories per pound. This can easily be achieved if one eats freely of unrefined, unprocessed fruits, veggies, starchy veggies, and intact whole grains and legumes. It is important to note that this means without the addition of salt, sugar and/or fat/oil to them. Never Diet Again by Following the Caloric Density Eating Approach Using the caloric density approach is one that is truly simple and based on common sense. Better yet, it is easy to stick with which allows you to manage your weight for the rest of your life without dieting. Because you essentially end up eating more food with fewer calories, you will feel satiated and happy. In a nutshell, by having a rough idea of how many calories there are in a given weight of food, one can enjoy a larger amount of food without increasing their total daily caloric intake. Foods that fall in this category tend to be whole,

  • Dr. Day’s 8 Scientifically Proven Ways to Lower Your Blood Pressure Naturally

    Dr. Day’s 8 Scientifically Proven Ways to Lower Your Blood Pressure Naturally
    2021/11/06
    8 Scientifically Proven Ways to Lower Your Blood Pressure Naturally Studies show that up to 90% of all Americans will have high blood pressure by age 50! But yet isolated groups of people cut off from our modern lifestyles have normal blood pressures in the range of 110/70 mmHg throughout their lives without the need for medications. If your goal is to optimize for normal sinus rhythm, a heart free of disease, and a long healthy life, you have to maintain a healthy blood pressure throughout your life. In this article, I will share my 8 scientifically proven ways to lower your blood pressure naturally. My Struggle with High Blood Pressure Ten years ago my blood pressure typically ran 140/90 mmHg. And as a cardiologist knowing of the cardiac dangers of high blood pressure, I put myself on a blood pressure-lowering medication. However, as I lived among the centenarians in the remote Longevity Village area of China, my goal was to naturally reverse all of my medical conditions, including high blood pressure. And by adopting a 99% natural plant-based diet, including a 30-pound weight loss, in conjunction with regular daily exercise, time with my family, and optimization of my sleep and stress levels, my unmedicated blood pressures now consistently run 110/90 mmHg! Below are the 8 scientifically proven ways I lowered my blood pressure. But if you are currently taking high blood pressure medications, please speak with your doctor first before trying anything in this article. My concern is that on one hand stopping blood pressure medications could be life-threatening. But yet, on the other hand, getting super healthy while taking blood pressure medications could drop your blood pressure to dangerously low levels. If your goal is to get off blood pressure medications, it will take exceedingly close monitoring while at the same time working with your doctor as you wean off medications. 1. Cut the Sodium First, you’re going to need to eat a low-sodium diet. This can offer a 4-point reduction in your systolic blood pressure, an effect equivalent to about half a typical blood pressure-lowering medication. 2. Eliminate any Added Sugars Second, you’ll need to eliminate any added sugars. That’s generally worth a 7-point reduction. 3. Commit to a Daily Workout Next, it’s time to commit to a daily workout for a 6 to 7 point reduction. 4. Drop Some Weight The fourth thing is really hard to do by itself, but a ton easier if you’ve done the first three things: You’ve got to drop some weight. How much? Broadly speaking, for every 2 pounds you lose you could expect a 1 point reduction. So, dropping 20 pounds could get you a 10 point reduction. 5. Embrace a High Fiber Diet Next, you’ll want to embrace a high-fiber diet. And to get there you'll need to eat a lot of vegetables, legumes, and high fiber fruit like berries. My personal goal is 100 grams of fiber daily but something much less than that could still be worth another 6 point reduction. 6. Learn to Eat Plant-Based Sixth, eating a mostly natural plant-based diet that is high in potassium and magnesium with limited saturated fats has been shown to drop your blood pressure by 6 points. 7. Get More Nitric Oxide from Greens and Root Vegetables Next, you need to get some more nitric oxide from greens and root vegetables. Eat enough of that molecule, the intake of which causes blood vessels to relax and dilate, and you could enjoy a 5 point reduction in your systolic blood pressure. 8. Lower the Stress Levels Finally, you’ve got to do something about your stress, which you already know is a key driver of high blood pressure. That can help drive a 5 point reduction in your systolic blood pressure. Disclaimer The content provided in this article is for informational purposes only.

  • Dr. Day’s 13 Simple Weight Loss Tips That Actually Work

    Dr. Day’s 13 Simple Weight Loss Tips That Actually Work
    2021/11/02
    13 Simple Weight Loss Tips That Actually Work Authored by Kate Clemens with Dr. John Day As Dr. Day revealed in his book, The Longevity Plan, he has struggled to maintain a healthy weight since high school. Indeed, 84% of all Americans report that they have tried to lose weight. Below are our 13 simple weight loss tips that actually work for us and our patients. 1. Diets Don't Work, Lifestyles Do You go on a diet and then you go off the diet--Diets were never meant to be long-term solutions. The goal is to find a way of eating that you can maintain for the rest of your life. So the next time you commit to "eating healthy," ask yourself can I eat like this for the rest of my life? If the answer is "no," then you're doomed to fail. You need a lifestyle or way of eating that you can easily maintain until you turn 100. 2. Faithfully Follow Dr. Day's 3 Rules to Eating As there is so much confusion as to what is healthy eating, Dr. Day's approach is to give his patients 3 simple rules to follow. And if you can just follow these 3 easy rules to eating, then you are 90% of the way there to healthy eating. First, minimize or avoid any added sugars. We do not need these! Real whole fruits are naturally occurring sugars, these do not count. Second, minimize or avoid processed foods. If it comes from a box, can, package, fast food window, etc. it is processed. You do not need these "foods." The more natural you eat the better. Third, eat as many non-starchy vegetables as you can. The more variety in the color of your vegetables the better. 3. Find What Works for You There is no one perfect diet for everyone. Just because "keto" worked for your friend doesn't mean it will work for you. For example, everyone says exercising first thing in the morning is best as it will help you to eat healthy all day long. Dr. Day found that exercising in the morning just made him hungry all day long. So for Dr. Day, he can control his eating by exercising late in the afternoon or after dinner. You are so wonderfully individual. While there are certainly a lot of health "guidelines" out there, these guidelines may or may not help you. Have fun, experiment, and be true to yourself. Remember the ONLY person you should ever compare yourself to is the person you were yesterday. 4. Crash Diets Crash Your Metabolism Have you ever wondered what happens to the “biggest losers” on reality TV shows? When the cameras stop rolling, do their incredible transformations stick? Not usually. Researchers have found, in fact, that these contestants’ crash diets send their metabolism into a tailspin, making long-term weight maintenance nearly impossible. In most cases, the weight comes right back and, even six years later, their metabolism is slower than it was before they started filming. This is what scientists call “metabolic adaptation” and is something you definitely want to avoid. No matter where you are in all facets of your life, getting to where you want to be is not supposed to happen overnight. After all, you probably put the weight on at a pace of 1 to 2 pounds a year. Do not be afraid of achieving your goals slowly and mindfully, just be sure you are moving forward! We are aiming for progress, not perfection. 5. Have a Daily Plan We do not plan to fail, we fail to plan. This is a well-known quote for a good reason. Set yourself up for success! Figure out 5-minute ‘planning window’ either each Sunday or the night before to sketch out what your food week or food day will look like. For example, as Dr. Day is surrounded by unlimited free treats at every nurse station or the doctor's dining lounge in the hospital, he has to plan out a daily "healthy treat." Without a prepared "healthy treat" in his laptop bag, he'll feel deprived and devour the unhealthy ones at his hospital. Prioritize self-care as much as you prioritize work. Believe me, it will make you that much more efficient! 6.

  • Can You Exercise with AFib?

    Can You Exercise with AFib?
    2021/10/16
    Can You Exercise with AFib? Can you exercise with AFib? And if so, how high can your heart rate go before it is unsafe? We all know that exercise is good for you but does that still hold if you're in AFib? If you or a loved one has AFib, read on to learn more. Does Exercise Cause AFib? Most of my patients are shocked to learn that people who run marathons, competitively cycle, or do Ironman triathlons are five times more likely to develop AFib! What is particularly perplexing, however, is that studies have not tended to show higher rates of arrhythmias in athletes who participate in other strenuous forms of exercise, such as boxing, wrestling and weight-lifting. There is something particular about endurance sports that increases the risk of AFib. One exception to this may be football. Among former NFL athletes, the risk of AFib is six times higher, although this may be due to the use of performance-enhancing substances or the weight these athletes put on to compete at a professional level. Also, it bears noting that while aggressively competing in endurance sports might put you at a greater risk of AFib, participation in these activities certainly does not guarantee you’ll get AFib. It is reassuring to note that non-competitive recreational participation in endurance sports, even if it is a marathon or triathlon, doesn’t seem to put you at risk of AFib. I have found over the years that almost all of my athletes with AFib have opted for an early ablation. They simply can't or don't want to exercise with the usual cocktail of AFib drugs that are prescribed. And fortunately for athletes, we typically get excellent results as studies show that the AFib ablation success rates are up to 3 times higher with athletes! Does Exercise Prevent AFib? Regular exercise in general isn’t risky at all. In fact, for 99.9% of my patients it’s exceptionally protective. To put things into perspective, for every thousand patients I see with atrial fibrillation, perhaps one may be at risk due to overexercising. The biggest problem, by far, is that most patients aren’t exercising enough. There is far greater risk to not exercising enough than to exercising too much. People who live sedentary lifestyles are at significant risk of AFib, not to mention all of the other health consequences of not getting enough exercise. Indeed, one study showed that not exercising at all increased your risk of AFib by more than four times! A big problem for many of my AFib patients is that they want to exercise but either the AFib or their medications make them so tired that they simply can't exercise. And for those people who can't exercise with AFib, we typically end up treating them with an ablation as the health benefits of exercising are too great to ignore. How High Can Your Heart Rate Go when Exercising in AFib? As exercise drives the heart rate up, how high can you let the heart rate go when exercising in AFib? For the vast majority of my patients, they are perfectly okay driving their heart rates up to their maximally predicted heart rate. And your maximally predicted heart rate is 220 minus your age. So if you are 40 years old, I would expect you to hit a heart rate of 180 with high levels of exercise. Of course, if you get chest discomfort or shortness of breath with exercise then you need to notify your cardiologist immediately as your life could be at risk. How Hard Can You Push Your Heart with Exercise and AFib? If you love endurance sports, it is perfectly fine to participate as long as your cardiologist is in agreement and your heart feels great during exercise. And if you want to be safe running that marathon, try slowing your running pace. Indeed, among my "plodder" patients, or those who exercise at slow non-competitive speeds, I rarely see AFib. Dr. Day's 3 Thoughts on Exercise and AFib 1. The health benefits that come from exercise are too great to ignore. Everyone should exercise every day.
