Walking linked to lower dementia risk

A 2022 study of 78,000 healthy people (ages 40 to 79) who wore fitness trackers found that people who walked about 9,800 steps per day (about five miles) were 51% less likely to develop dementia, compared with people who didn't walk much at all.

Cold-weather cautions

Wintertime can pose challenges to cardiovascular health. Cold temperatures can cause arteries to narrow, which can leave people with heart disease vulnerable to angina or heart attacks, especially during physical exertion. Changes in sleep, eating, and exercise habits related to the season may also affect the heart. Crowded indoor gatherings also raise a person's risk for respiratory infections, which can exacerbate heart disease.

The heartfelt benefits of pet ownership

Having a dog or another pet appears to lower the risk of high blood pressure and improve blood pressure control. Pet ownership may foster positive feelings (such as decreased stress) and habits (such as daily walks) that may improve heart health. People who own dogs walk about 20 minutes more per day on average than those without dogs. Pets can help combat loneliness and social isolation, which have been linked to a higher risk of heart attack, stroke, or death from these causes.

Can a multivitamin keep your brain healthy?

A recent study found that older adults who took a multivitamin daily for three years had improved scores on tests of executive function, memory, and overall brain function, but the study wasn't large enough, long enough, or diverse enough to rely on its conclusions alone.

Beyond momentary calm

Mindfulness is the act of paying attention and focusing on the moment. Research has long shown mindfulness can help lower anxiety, but new studies suggest additional benefits. These include feeling less pain, making fewer mistakes, and being more resilient. Many people confuse meditation with mindfulness. Although there is some overlap, meditation is a practice that leads to being more mindful. Both meditation and mindfulness aim to help people stay present and nonjudgmental.

A life-changing detour

Each year, millions of couples face one partner's serious diagnosis with a condition such as cancer, heart or kidney failure, or neurological illness, among others. People can support their partners through a difficult diagnosis and treatment by keeping communication open, maintaining daily routines, becoming informed about the medical condition, attending doctor visits, adding assistive devices in their home, getting wills and other legal documents in order, and seeking and accepting help from others.

Building a "cognitive reserve" offers brain protection in old age

A 2022 study suggests that following certain healthy habits throughout life can create a "cognitive reserve" that may protect the brain from dementia. People in their 60s and 70s can still build up their reserve by pursuing a combination of brain-stimulating activities.
