The health benefits of dancing are as beneficial as other forms of exercise, and are accessible to almost everyone regardless of age or range of mobility. Moreover, by incorporating music, dance may have benefits beyond those of exercise alone. Music stimulates the brain’s reward centers, while dance activates its sensory and motor circuits. Dancing has improved balance, gait, and quality of life in people with Parkinson’s disease and related movement disorders.
Last year, the Alzheimer’s Association predicted that rates of dementia would continue to rise. However, a report recently published in the New England Journal of Medicine found that rates of dementia have actually dropped steadily over the past three decades. Whether the drop in rates applies to everyone, and whether it will continue, remain to be seen. But the evidence also confirms that there’s quite a lot you can do to lower your dementia risk.
There’s almost always something we can do to improve our health and well-being — even at the end of our lives. Palliative care is designed to improve the quality of life for people with life-threatening illnesses and their families by keeping a person comfortable and making sure his or her values and preferences guide the medical team’s actions. For this reason, good communication with your care team — and your loved ones — is essential, even before you or a loved one has developed a serious illness.
Home visits from insurance companies reimbursed by Medicare are intended to help ensure that patients who are frail or have chronic health conditions can still get coverage. However, these visits may also contribute to higher health care costs. Before you welcome your health plan’s clinician into your home, here’s what you should know.
Music therapists are trained and certified to help patients in many ways. Research suggests that music therapy is more than just a nice perk. It can offer real benefits in reducing pain, anxiety, and improving quality of life for people with dementia.
How much calcium do you really need for strong, healthy bones? The answer isn’t as clear as we once thought. Recent analyses suggest that neither dietary calcium nor calcium supplements reduce the risk of fractures. In the absence of a clear deficiency, it’s impossible to know how exactly much calcium a person needs. Ideally, you should get most of your calcium through food. Be sure you’re getting adequate vitamin D as well.
These days, more and more adults bike to work, combining their daily workout with their daily commute, all while helping the environment. Unfortunately, biking is getting riskier. A study in this week’s Journal of the American Medical Association found that, between 1998 and 2013, the rate of bike injuries rose by 28% and the rate of people admitted to the hospital because of bike injuries rose by 120%. People over 45 had the greatest increase in injuries. And the majority of bike accidents now happen on city streets. The good news is that you can help protect yourself by learning and following the rules of the road, staying alert, and keeping some common-sense safety tips in mind.
Vitamin D holds promise for many things, like building bone, preventing heart attacks and strokes, reducing cancer risk, and more. But that promise isn’t fully backed by science. For example, a controlled clinical trial published this week in JAMA Internal Medicine found that a vitamin D supplements didn’t build bone in postmenopausal women with blood levels of vitamin D below the threshold generally considered necessary for good health. Many researchers are looking ahead to results from an ongoing trial called VITAL, which aims to gather the kind of solid evidence that will let us know for sure whether taking relatively high doses of vitamin D can ward off heart attack, stroke, or cancer. The results are expected by the end of 2017. It’s also possible to get vitamin D the old-fashioned way: go out in the sun between 10 a.m. and 3 p.m. with at least 10% of your skin exposed. Stay out long enough to absorb the sun but not long enough to be burned.
People with allergies to grass pollen may have cheered last year when the FDA approved a no-needles treatment —a daily tablet you dissolve under your tongue. These tables deliver low doses of grass pollen to the bloodstream. This is done to “teach” the immune system not to wage war on grass pollen. It turns out that these tablets don’t work that well. An analysis of 13 controlled clinical trials indicates that dissolvable tablets are only slightly more effective than placebos in curtailing classic symptoms of grass pollen allergy—runny nose, itchy eyes, and tickly throat. To make matters worse, more than 60% of people who used the tablets experienced irritating side effects.
The search for an effective, easy-to-use treatment for sleep apnea has been going on for years. The gold standard is a breathing machine known as continuous positive airway pressure (CPAP). A report published online this week by JAMA Internal Medicine describes a mouth-guard-like device that may work for people with mild sleep apnea, but that may not be much help for those with severe sleep apnea. The 18 million Americans with obstructive sleep apnea sufferers are a powerful incentive for device manufacturers, and there are myriad alternatives to CPAP in the marketplace and under development. Swedish researchers tested a custom-fitted mandibular advancement device among people with self-reported sleep apnea. It worked, but a placebo device worked almost as well.
