Hearing aids can cost thousands of dollars, but a study in the July 4, 2017, Journal of the American Medical Association found that less expensive over-the-counter personal sound amplification products (PSAPs) might be a good alternative for some people.

PSAPs resemble hearing aids and help amplify sounds the same way, but are not regulated by the FDA and thus cannot be marketed as a correction or treatment for hearing loss. They often are advertised as being helpful in noisy places like crowds and meetings, and are sold online for about $200 to $400.

Q. I recently decided to give up soda and switched to flavored seltzer water. Is this a better choice for my health?

A. First, congratulations on giving up soda. Sugary drinks like soda have been linked to an increased risk of type 2 diabetes, heart problems, and other chronic health conditions, so that is definitely a win for your health. Switching to seltzer is a much better choice, provided you choose a brand that is sugar- and calorie-free.

If the treadmill in your bedroom looks more like a coat rack than a piece of workout equipment, you're not alone. Many women struggle to commit to and keep up with a regular exercise program.

Often, they've got legitimate reasons for skipping those workouts.

Some women squeeze in exercise by using active workstations, which enable them to move more during the workday. But you may wonder: will this type of multitasking make you less productive on the job?

A study in the May issue of Medicine & Science in Sports & Exercise says it doesn't appear to. The study authors tested the cognitive performance of 58 workers — 32 young and 26 middle-aged — who were asked to walk for 50 minutes at a time on an active workstation treadmill. The study authors concluded the walking didn't hinder the workers' ability to effectively complete mental tasks, aside from a slight dip in planning skills during the workout. And they were able to log an average of 4,500 more steps per day during their sessions.

Let's cover the original misinformation first: The earliest missives warned that microwaved plastic releases cancer-causing chemicals called dioxins into food. The problem with that warning is that plastics don't contain dioxins. They are created when garbage, plastics, metals, wood, and other materials are burned. As long as you don't burn your food in a microwave, you aren't exposing yourself to dioxins.

Migrating chemicals

There's no single substance called "plastic." That term covers many materials made from an array of organic and inorganic compounds. Substances are often added to plastic to help shape or stabilize it. Two of these plasticizers are

Q. I've been trying to avoid high-fructose corn syrup. Is table sugar a healthier alternative?

A. Wouldn't it be nice if there were a healthy sugar that you could eat guilt-free? Unfortunately, when it comes to high-fructose corn syrup and table sugar, there really isn't a "good" option. High-fructose corn syrup and table sugar are actually pretty similar from a chemical standpoint.

While many women dream of kicking back and relaxing into retirement, there's increasing evidence that in some cases, it's better for your brain and your health to keep your nose to the grindstone a little longer.

"The research to date is mixed, but it tends toward the positive — that is, for many people, there are health benefits to working longer," says Dr. Nicole Maestas, associate professor of health care policy at Harvard Medical School.

Dog is a woman's best … workout buddy? Maybe, says a study published online June 9 by BMC Public Health, which found that having a dog appeared to increase physical activity in older adults.

Researchers asked 43 pairs of dog owners and non-owners to wear an activity monitor for a week to track their physical movements. Subjects wore the device three times over the course of one year. They also kept an activity log that included information about themselves and their dog, as well as their daily schedule. As it turns out, the dog owners spent more time walking than those without a dog, and they also took about 2,670 more steps each day. So, if you've been thinking about getting a dog this might give you one more reason to consider a furry friend.

Can getting quality sleep help prevent the disease?

A good night's sleep does more than rejuvenate you for the next day. It may help protect you against Alzheimer's disease. Research has begun to show an association between poor sleep and a higher risk of accumulating beta-amyloid protein plaque in the brain, one of the hallmarks of the disease.

"Observational studies have found that adults over age 65 with amyloid plaques in their brain have reduced slow-wave sleep, which is thought to play an important role in memory function, even though these people do not yet show signs of Alzheimer's, like memory loss and cognitive decline," says Dr. Brad Dickerson, associate professor of neurology at Harvard Medical School. "It may be that quality sleep could play a role in who may get Alzheimer's."
