Do you have trouble sleeping? If you’re carrying extra pounds, especially around your belly, losing weight and some of that muffin top may help you get better ZZZs. So say researchers from Johns Hopkins University School of Medicine, who presented their findings at this year’s annual meeting of the American Heart Association. In a six-month trial that included 77 overweight volunteers, weight loss through diet plus exercise or diet alone improved sleep. A reduction in belly fat was the best predictor of improved sleep. Among people who are overweight, weight loss can reduce sleep apnea, a nighttime breathing problem that leads to frequent awakenings. Exercise has also been shown to improve sleep quality. Despite what thousands of websites want you to believe, there are no exercises or potions that “melt away” belly fat. Instead, the solution is old-fashioned exercise and a healthy diet.

For all too many people, using a tablet computer is a pain in the neck, shoulders, and back. Why? Widely popular tablets like the iPad, Nook, Kindle Fire, and Xoom are so light and easy to handle that you can hold one on your lap or in your hand. That can put you in a position that’s bad for your neck, shoulders, and back. In a study of 15 experienced tablet users, Harvard School of Public Health researchers found that working with a tablet held on the lap or placed flat on a table makes the neck bend much more than does working with a desktop or notebook computer. Neck-wise, the best tablet orientation was having it propped up on a table. Next time you expect to be working with a tablet computer for more than a few minutes, place it on a table and use a case that holds it at a comfortable viewing angle. Shift your hands, your weight, or even stand up when you can. And take a break every 15 minutes.
Succulent tomatoes are far more than just a delicious fruit. Eating them may also help lower your risk of stroke, likely due to the lycopene they contain. Lycopene is a powerful antioxidant that eliminates dangerous free radicals that can damage DNA and other fragile cell structures. Past research has shown that a diet rich in lycopene-containing foods may help lower the risk of prostate and other cancers. Now, in a report just published in the journal Neurology, a team of Finnish researchers has linked higher lycopene levels in the blood to protection against stroke. The researchers suggested that lycopene, in addition to its ability to attack free radicals, may also reduce inflammation and cholesterol, improve immune function, and prevent blood from clotting. All of these may help reduce ischemic strokes, which are caused by clot-caused blockages in blood flow to the brain. It’s best to get lycopene from food—tomatoes and watermelon are excellent sources—not supplements.
Scientific studies, the media, and even some doctors tout the heart health benefits of red wine. But if controlling blood pressure is important to you, consider this the next time you raise your glass: A new study published online in Circulation Research suggests that non-alcoholic red wine may be better at lowering blood pressure than regular red wine. Powerful antioxidants in red wine called polyphenols may be more effective when there’s no alcohol to interfere with them. Spanish researchers compared the effects of regular wine, non-alcoholic red wine, and gin on blood pressure. Non-alcoholic red wine lowered blood pressure and boosted levels of nitric oxide, which helps relax blood vessels. What the study doesn’t tell us is how non-alcoholic red wine stacks up against regular red wine for preventing heart attacks or other cardiovascular problems.
Migraines can be debilitating events. As Harvard Health editor Christine Junge wrote in this space last year about her battle with migraine, “On the days when I couldn’t get out of bed, it felt like someone was tightening screws into the sides of my head and pounding a hammer above my left eye.” Most migraine sufferers long to prevent these painful episodes. About one-third of migraineurs could benefit from taking a preventive pill. But only a minority of them actually take advantage of this option. New treatment guidelines from the American Academy of Neurology and the American Headache Society profile the best preventive medications, and an herbal preparation, for migraine. Preventive medications include antiseizure drugs, beta blockers, antidepressants, and triptans. The guidelines also indicate that an herbal remedy made from butterbur, a plant in the daisy family, can help prevent migraine. The downside of these preventive pills is that they must be taken every day, and may cause unwanted side effects.
A condition called benign paroxysmal positional vertigo (BPPV) causes bursts of intense dizziness. It happens when tiny crystals of calcium carbonate in one part of your inner ear become dislodged and float into another part of the ear. A simple set of physical motions called the Epley maneuver can move the crystals into another ear chamber, where they’ll be absorbed by the body. The maneuver is so simple it can be done at home. Writing in the journal Neurology, researchers looked at how people were using YouTube videos of the maneuver to treat their vertigo at home. I watched one of the videos and tried the maneuver. It didn’t work for me. But I did some investigating to find out why, and have some tips to improve your odds of success.
If you start an exercise program, it only seems fair that you should see your hard work reflected in lower numbers on the scale. If it isn’t, don’t despair—or quit exercising. You are still helping your heart, lungs, and every other part of your body. A study in the Journal of the American College of Cardiology looked at the effects of exercise and/or weight loss on cardiovascular health among more than 3,000 men and women who were initially overweight. As I write in the July issue of the Harvard Health Letter, those who exercised consistently and lost weight had the biggest reduction in heart attack risk over six years of follow-up. Exercising without losing weight and losing weight without exercising offered smaller benefits. Although exercise and weight don’t always move in the same direction, they are both important for health.
After a hospitalization, being discharged is a key step on the road to recovery. But that road can take a dangerous turn—namely, a serious problem with one or more medications. It’s a common problem that many people experience within a few weeks of leaving the hospital. Researchers at Brigham and Women’s Hospital now report in […]
A new book from First Lady Michelle Obama, “American Grown: The Story of the White House Kitchen Garden and Gardens Across America,” details the challenges and joys the First Lady has experienced with her now-famous White House garden. It also looks at community gardens all across America, and how they can improve health. The book contains helpful hints for starting your own vegetable garden, as well as a school or community garden. This effort dovetails with Mrs. Obama’s “Let’s Move” initiative. In addition to getting more physical activity, so the thinking goes, eating more food harvested from the ground and less from packages can help kids — and adults — become healthy or stay that way. The health benefits of growing your own food range from helping you eat more fresh fruits and vegetables to deciding what kinds of fertilizers and pesticides come in contact with your food.
Some encouraging Alzheimer’s news from Sweden: a vaccine called CAD106 appears to be safe and ramps up the body’s immune system against a protein likely involved in Alzheimer’s. The hope is that this vaccine will slow the progression of Alzheimer’s disease, and possibly even stop it. The vaccine is designed to activate the body’s immune system against beta amyloid, a protein fragment that forms deposits called amyloid plaques between nerve cells in the brain. Three-quarters of those who received CAD106 developed antibodies against beta amyloid protein. Virtually all of them—including those getting the placebo—reported one or more side effects, ranging from inflammation of the nose and throat to headache, muscle pain, and fatigue. None, though, developed meningoencephalitis, an inflammation of brain tissue that derailed work on an earlier version of the vaccine. The next step in the development of CAD106 is a larger clinical trial to confirm the vaccine’s safety and to see if it is effective at slowing the relentless progression of Alzheimer’s disease.
