A small study supports the idea that exercising improves body image, whether or not the activity leads to any visible change in appearance. This suggests that additional research examining different types of exercise, and the long-term psychological effects of physical activity would be valuable.

Sometimes pain has a purpose — it can alert us that we've sprained an ankle, for example. But for many people, pain can linger for weeks or even months, causing needless suffering and interfering with quality of life.

If your pain has overstayed its welcome, you should know that you have more treatment options today than ever before. Here, we've listed eight techniques to control and reduce your pain that don't require an invasive procedure — or even taking a pill.

As currently structured, the American health care system makes it very difficult for those with chronic illnesses to manage their conditions, causing them to perform the equivalent of unpaid labor.

It's no secret that alcohol affects our brains. Although excessive drinking is linked to an increased risk of dementia, decades of observational studies have indicated that moderate drinking has few ill effects. However, a recent British study seems to have bad news for moderate drinkers.

Stay ahead of age-related changes in thinking skills by making the most of your brain's memory process.

We all have moments of forgetfulness about where we put the keys, why we walked into a room, or what an object is called. Most likely, this reflects age-related changes in thinking skills. "In terms of brain function, everyone has a decline over time in all areas, with the exception of vocabulary," says Dr. Joel Salinas, a neurologist specializing in behavioral neurology and neuropsychiatry at Harvard-affiliated Massachusetts General Hospital.

How memory works

Memory involves three processes: encoding, recording, and retrieval. The brain receives and encodes (takes in) new information; the brain then records (stores) the information; finally, the brain retrieves information when you need it.

A review of research published online April 24, 2017, by the British Journal of Sports Medicine suggests that physical exercise may help improve thinking skills in adults ages 50 or older, regardless of their mental performance when they started exercising. Researchers combed through 39 randomized controlled trials that looked at this age group. Most of the studies involved people who did aerobic exercise (the kind that gets your heart and lungs pumping, like brisk walking), resistance training (the kind that works your muscles and bones, like weight lifting), or a combination of aerobics and resistance training. A handful of the studies involved people who did yoga or tai chi. In all of the studies, participants took tests that measured various aspects of thinking skills — such as attention, working memory, and the ability to plan, organize, and manage time. All exercise types but yoga appeared to have benefits for the brain. The authors say the exercise regimen with the biggest brain boost was a combination of both aerobic and resistance-type training, of at least moderate intensity, for at least 45 minutes per session on as many days of the week as possible. The takeaway? Start exercising, and incorporate resistance training into your weekly routine.

A study in the December 2016 Journal of Nutrition, Health & Aging showed that drinking tea frequently is associated with a lower risk of dementia, especially for people who are genetically predisposed to the disease.

Researchers followed 957 older adults, average age 65, who were part of the Singapore Longitudinal Aging Study. Of these, 69% drank tea on a frequent basis. After a five-year period, the researchers found that the tea drinkers had a 50% lower risk of dementia. This is consistent with earlier findings that showed tea consumers scored higher on various cognitive tests.

Creative activities can relieve stress, aid communication, and help arrest cognitive decline.

The title of a recent documentary film, I Remember Better When I Paint, sums up the findings of a growing body of research into the cognitive effects of making art. The movie demonstrates how drawing and painting stimulated memories in people with dementia and enabled them to reconnect with the world. People with dementia aren't the only beneficiaries. Studies have shown that expressing themselves through art can help people with depression, anxiety, or cancer, too. And doing so has been linked to improved memory, reasoning, and resilience in healthy older people.
