Most people experience some degree of decreased memory as they get older, but memory performance is also affected by mood and sleep quality, and these are factors that can be controlled and improved.

Tooth decay is linked to a higher risk of many health problems in adulthood, but often families don’t put enough emphasis on proper and consistent dental care. Avoiding these mistakes can help your children get the right start on their oral health.

Listening to music can be relaxing, but it may interfere with your ability to create, suggests a study published online Feb. 2, 2019, by Applied Cognitive Psychology. Researchers recruited 30 people and tested their creativity through a series of exercises. Participants were shown three words at a time and then asked to add another word to create a new word or phrase. For example, "sun" could be joined to words like "dress," "dial," and "flower." The creativity exercises had three levels of difficulty: easy, moderate, and hard.

The group also did the exercises in different noise environments — silence; music with Spanish and English lyrics; instrumental music; and normal background library sounds like distant speech, typing, and paper rustling. They found that every kind of music significantly impaired the ability to complete the creativity tasks, while silence and library noises had no effect.

A strong social life has been linked with many health benefits, like less risk of depression and longer life span. But a new study suggests that interacting with a wide range of people may offer even greater benefits.

The study, published Feb. 20, 2019, in The Journals of Gerontology, Series B: Psychological Sciences and Social Sciences, found that older adults who interacted with people beyond their usual social circle of family and close friends were more likely to have higher levels of physical activity, greater positive moods, and fewer negative feelings.

Managing emotionally driven weight gain requires planning ahead.

How much and when you eat isn't driven just by hunger, which you likely already know if you've ever found yourself hunched over a bowl of ice cream after having a particularly stressful day. Stress can set off a cascade of physical reactions in your body that may not only drive you to eat more and make you crave less nutritious, fattening comfort foods, but also help you pack on extra pounds much more easily.

"Stress drives up levels of a hormone called cortisol in the blood," says Dr. Fatima Cody Stanford, an instructor in medicine at Harvard Medical School. Cortisol is a hormone produced by the adrenal gland that helps to regulate your metabolism. It also plays a role in blood sugar management and memory. When levels of cortisol rise, it can promote inflammation and may spur the body to start stockpiling fat around the midsection. "Stress might also disrupt sleep and drive people to seek out food when they wouldn't normally — such as in the middle of the night," says Dr. Stanford.

This age-old relaxation method can bring health benefits, and there are many tools to help get you started.

These days it seems like there's an app for almost everything you can do for your health, from tracking your diet and exercise to charting your sleep patterns. So, it's no surprise that there's been a surge in apps to help with meditation, an ancient practice designed to help you focus inward to promote relaxation.

In fact, Apple designated "self-care" — a category that includes meditation, mindfulness, and general wellness — as the 2018 "app trend of the year." This mirrors growing interest in meditation as an overall health strategy, a movement likely driven by a growing body of research showing potential health benefits from the practice.

People bereaved by a suicide often get less support because it's hard for them to reach out — and because others are unsure how to help.

Every year in the United States, more than 45,000 people take their own lives. Every one of these deaths leaves an estimated six or more "suicide survivors" — people who've lost someone they care about deeply and are left with their grief and struggle to understand why it happened.

The grief process is always difficult, but a loss through suicide is like no other, and the grieving can be especially complex and traumatic. People coping with this kind of loss often need more support than others, but may get less. There are various explanations for this. Suicide is a difficult subject to contemplate. Survivors may be reluctant to confide that the death was self-inflicted. And when others know the circumstances of the death, they may feel uncertain about how to offer help. Grief after suicide is different, but there are many resources for survivors, and many ways you can help the bereaved.

Concern about the amount of sugar in kids’ diets has led the American Academy of Pediatrics and the American Heart Association to encourage the consideration of steps to reduce the consumption of sugary drinks among children and teens.

The recent college admission scandal has raised the issue of parents helping their children succeed. Regardless of where (or whether) someone goes to college, parents and other caregivers can help children learn the traits and skills that will help them learn how to find their way in the world.

Q. When we lose memories, do we lose them forever? A friend told me they may still be in our brains.

A. Our memories are stored inside nerve cells in our brains, often in multiple cells that communicate with each other. Each nerve cell looks a little like a tree, with a trunk, branches and, ultimately, little "twigs" (called spines). The spines of one cell communicate with those of another cell by releasing chemicals.
