Dental x-rays have long involved donning lead-lined shields. But new guidelines from the American Dental Association say that using the vest is no longer necessary. What has changed?

Recent changes in laws have made gambling widely accessible and popular. Uncontrolled gambling can have many kinds of consequences, some quite serious. A simple screening test for problem gambling and knowing the range of available resources can help people ward off the worst of these issues.

If you've been cocooning due to winter's cold, who can blame you? But lack of activity isn't good for body or mind during any season. Any day is a good day to start exercising, but if you aren't sure how to start, or if you have an obstacle to overcome, read on.

A 2023 study found that people who said they ate the most tomatoes (more than 110 grams per day, for three years) experienced a 36% reduction in hypertension, compared with people who said they ate the least tomatoes per day (less than 44 grams).

A 2023 study found that pet owners who lived alone had slower rates of cognitive decline compared with people who lived alone but had no pets. Living with a dog or cat may help ease loneliness - an important risk factor for cognitive decline.

It's dangerous to keep unneeded or expired medications around the house. But it's bad for the environment to simply flush or throw away the drugs. It's best to dispose of them by bringing them to a drug take-back site (such as a drugstore or law enforcement office) or a medical waste collection site (such as the local landfill). As a last resort, it's okay to toss medications into the trash with careful preparation. The FDA recommends mixing medicines with unappealing substances, such as cat litter or used coffee grounds; placing the mixture in a sealable plastic bag or container; and throwing the bag or container in the trash.

People with heart disease may benefit from daily aspirin therapy to help reduce the risks for blood clots that cause heart attacks. A 2023 study suggests that neither the aspirin dose (81 mg vs. 325 mg) nor whether it is enteric-coated or uncoated affects the benefits or risks of daily aspirin therapy. However, aspirin carries the risk of brain and stomach bleeding. Some doctors maintain that people with heart disease are better off taking one low-dose, enteric-coated aspirin pill a day.

It's a good idea to eat a certain diet before and after a colonoscopy. Eating a low-fiber diet a few days before the procedure helps move foods through the colon quickly, which can make colon prep easier. On the day before the procedure, it's important to consume only clear liquids (such as broth or bouillon, black coffee, plain tea, clear juices, clear soft drinks or sports drinks, Jell-O, and popsicles). After the procedure, it's safe to resume a normal diet. But eating too much fiber too quickly might cause gas, bloating, and discomfort. It might be wisest to restart a normal fiber-rich diet gradually.

Replacing just five minutes of sitting with moderate-to-vigorous physical activity may lead to tangible improvements in cardiovascular health. Adding longer, more intense bouts of exercise can reap greater rewards. But even modest changes such as replacing sitting with standing may lead to positive changes in health parameters, including improvements in body mass index, waist circumference, cholesterol, triglycerides, and blood sugar levels.

Common activity guidelines recommend a minimum of 150 minutes of moderate-intensity physical activity and two muscle-strengthening workouts per week. However, these targets are meant for a broad population, and for many older adults, hitting just the 150 minutes per week poses a challenge. Experts suggest breaking down the 150 minutes into manageable segments, like doing 30 minutes of activity five days a week, and even dividing those 30 minutes into 10 minutes of exercise three times a day.
