What Is It?

A person who is sleepwalking walks or makes other movements that seem purposeful. This occurs while in a state of partial wakefulness from deep sleep. Contrary to popular belief, sleepwalkers don't act out their dreams. Sleepwalking doesn't take place during the dreaming stage of sleep.

Sleepwalking is also called somnambulism. It is common in school-age children. Repeated sleepwalking is more common in boys. It is frequently associated with nighttime bedwetting.

Between 1959 and 2014, average life expectancy in the United States rose astoundingly by nearly a decade. Then it began declining. A recent report examining this situation raises tough questions about that unexpected change.

One of the first cultivated grains, wheat is now ubiquitous in the average American diet. In the United States, about 75% of all grain products (such as bread, pasta, tortillas, cakes, and pastries) are made with wheat. Unfortunately, most of these commonly consumed foods are made with white flour: wheat kernels that have been stripped of their outer bran and inner germ layers and milled into a fine powder. White flour is fortified with some of the vitamins and minerals removed during this refining process. But most of the fiber and other healthful plant-based chemicals found in intact whole grains are missing.

Eating more whole grains is linked to a lower risk of heart disease and cancer, which is why the federal dietary guidelines say to "make half your grains whole." But most people aren't even close to that goal. According to the CDC, whole grains account for only about 16% of the total grain-based food adults eat on any given day.

A recent study suggested that eating red or processed meats won't necessarily harm your health. What is the truth?

The news headlines were everywhere: "It's Okay to Eat Red Meat." The source for this statement was a study published online Oct. 1, 2019, in Annals of Internal Medicine.

An international team of researchers conducted five systematic reviews that looked at the effects of red meat and processed meat on multiple health issues, such as heart disease, cancer, diabetes, and premature death.

Q. I started having side effects from a prescribed drug. I stopped taking it, but the side effects are still there. How long does it take for a drug to be out of your system?

A. Most drugs will be out of your system quite quickly, but the symptoms of side effects may remain for some time. It depends on the medication and what kind of side effect has developed. The majority of prescription drugs are cleared out of your body rapidly by your kidneys and liver. Trace levels of a medicine may remain in the system while the liver and kidneys finish their filtering job. But these levels are often too low to have any noticeable effect. Patients with kidney or liver disease, however, can continue to have elevated blood levels of a drug even after stopping it.

Q. I'm 80 and no longer do colon cancer screening. However, I recently noticed some bleeding from my rectum. Does that change my need for a colonoscopy?

A. Screening for a disease means the person has no symptoms. Since you now have rectal bleeding, a colonoscopy would be considered not a screening test, but a diagnostic test. Whether you have it now or wait to see if more bleeding occurs depends upon many factors. The most important question is whether anything found on the colonoscopy will lead to treatment that improves your quality of life.

If you have put off cataract surgery, consider this: the procedure could make you a safer driver, according to research presented in October 2019 at the Annual Meeting of the American Academy of Ophthalmology.

Cataracts, in which the lenses of the eyes become cloudy, are a normal part of aging. Vision changes due to cataracts occur slowly, so people often don't realize they have trouble seeing at night and struggle with depth perception. While cataract surgery is low-risk and effective, many people avoid it because they feel their cataracts don't interfere with their quality of life.

People with high blood pressure may benefit from taking their antihypertension medication at bedtime instead of the morning, according to a study published online Oct. 22, 2019, by the European Heart Journal.

The researchers looked at about 19,000 people (most of them men) who took blood pressure medication. Participants took their daily dose either upon waking or before going to bed. Everyone's blood pressure was checked over 48 hours once a year for six years.

Exercises that promote strength and flexibility can help you improve your stance over time.

Chances are you do a lot to sabotage your posture during the course of an average day: reading a good book with your head down, sitting at a computer, or scrolling on your phone.

Activities like these can get your body in the habit of hunching or slouching. Over time this may lead to physical changes that make it harder to stand up straight and cause a curvature in your upper back, which doctors refer to as kyphosis.

Research we're watching

People who run — even in small amounts — are less likely to die during a given period compared with those who don't run, according to an analysis published online Nov. 4, 2019, by the British Journal of Sports Medicine. The benefit appears even among people who run for less than 50 minutes once a week, at speeds below 6 mph.

Researchers began their review of 14 studies, involving more than 200,000 people, in hopes of determining whether running can stave off deaths from heart disease, cancer, and other causes. They also sought to find out how much running people need to do to benefit. The studies tracked participants for periods ranging from five-and-a-half to 35 years. Over the course of these studies, 25,951 of the participants died. When comparing those people to those who lived until the end of the study, the researchers found that people who ran, no matter the amount, were 27% less likely than nonrunners to die from any cause during the study period. Runners also had a 30% lower death rate from cardiovascular disease and a 23% lower death rate from cancer. While running was linked with longer life and less disease in these studies, this doesn't necessarily prove that it was the running that actually caused better health. But the results suggest that lacing up those sneakers and going for a quick jog might improve your health.
