Getting in on the kettlebell craze
The weights add more oomph to your workout, but you'll have to mind some safety rules if you use them.

Move over, dumbbells; kettlebells are cool again. The little weights with handles have been used by athletes around the world for centuries and gained popularity as the staples of 19th-century strongmen. Today, kettlebells have made it to the mainstream as the featured tools in exercise classes and gyms, with home versions of kettlebells available on the shelves of every big-box store.
What's the attraction? "Kettlebells work multiple muscle groups at one time, so you get a lot of bang for your buck with each exercise," says Nancy Capparelli, a senior physical therapist at Harvard-affiliated Beth Israel Deaconess Medical Center.
Medications we're watching
News briefs
Three newly approved medications are garnering national attention. The first is an oral form of a powerful opioid painkiller that's been available by injection since 1984. Dsuvia is the sublingual (under the tongue) version of sufentanil, and it was approved by the FDA in November 2018. Dsuvia is 1,000 times more potent than morphine. The FDA says it may be helpful for use on the battlefield or in hospitals. Critics worry the drug will wind up on the streets, furthering the country's opioid crisis. Another medication of note is the first prescription drug made from marijuana. The FDA approved cannabidiol (Epidiolex) in June 2018 for the treatment of seizures associated with rare forms of epilepsy. The medication is made from a component of marijuana that does not cause intoxication or euphoria. And finally, baloxavir marboxil (Xofluza), the first new antiviral in 20 years to help fight the flu, received FDA clearance in October 2018. The drug is a one-dose pill that may help shorten the duration of the flu if it's taken within 48 hours of the start of symptoms. One caution: the new antiviral has not yet been tested in older adults, so talk to your doctor if the drug is prescribed and you have concerns.

A noisy problem
People often become more sensitive to noise as they age, which can affect their mental and physical health.

Are you more sensitive to noises than you used to be? Do certain sounds now feel too loud and jarring? Don't worry; it's actually quite normal.
Age-related hearing loss is common among older adults and affects about two-thirds of men in their 70s and 85% of men ages 80 and older. Although it's not clear why, this can also make people hypersensitive to sounds that they used to tolerate easily, which in turn can affect their well-being.
The lowdown on squats
Here is why squats may be the most important exercise you do.

More than half of an average person's day is spent sitting — from watching television to working at a computer — and that time tends to increase as you age and become less active.
All that sitting can have a profound impact on one's health, too. In fact, a study in the Oct. 3, 2017, Annals of Internal Medicine, involving almost 8,000 adults ages 45 and older, found a direct relationship between time spent sitting and a higher risk of early death.
New exercise guidelines suggest older adults try a variety of activities

For the first time in 10 years, the U.S. government has updated its guidelines for regular physical activity. The guidelines, published in the Nov. 20, 2018, issue of JAMA, still suggest adults get at least 150 to 300 minutes each week of moderate-intensity physical activity, and the more you can do, the better. Examples of moderate-intensity activities include brisk walking, swimming and cycling.
What is new are specific suggestions for certain age groups. For adults ages 65 and older, the report recommends their allotted minutes include multicomponent activities that offer balance training, aerobic exercise, and muscle strengthening, all of which can help older adults reduce their risk of falls. They noted that many recreational activities like dancing, yoga, tai chi, gardening, or sports often incorporate the multiple types of activity you need.
Fish oil and vitamin D supplements might offer some health benefits
In the journals
Vitamin D and omega-3 fatty acid supplements have had mixed results when it comes to preventing heart attacks, strokes, and cancer in people who have already developed these problems or are at high risk for them. Yet a new study published online Nov. 10, 2018, by The New England Journal of Medicine found they may actually prevent these conditions among people who have never had these problems before.
Researchers recruited almost 26,000 people, ages 50 and older, who had no history of heart disease or cancer. The participants were divided into four groups. People in one group were given daily doses of 2,000 international units of vitamin D (an amount found to be linked to lower disease risk in observational studies) and 1 gram of a drug called Lovaza, which contained 840 milligrams of omega-3s (two to four times the amount in two servings of fish per week). The second group took vitamin D and a placebo, the third group took the omega-3s and a placebo, and the final group took two placebos. After more than five years, the researchers found that those given omega-3s were 28% less likely to suffer a heart attack compared with those given a placebo. Those who ate fewer servings of fish (less than the average of 1.5 servings per week) appeared to have a greater benefit from the additional omega-3s while those with higher fish intake had minimal benefit.
Are workouts safe after a heart attack?
Ask the doctors
Q. My partner recently had a heart attack. The doctor recommended exercise, but I wonder if it's better to take it easy. I feel like exercise might be dangerous or even cause another heart attack. Is exercising too risky?
A. As counterintuitive as it might seem, exercise is good medicine for heart attack survivors. Provided the doctor gives the green light, about two-and-a-half hours of moderate-intensity exercise each week can be beneficial — this is the amount recommended by the American Heart Association. Exercise can start as soon as the doctor gives the okay.
Mediterranean diet works by adding up small improvements
Over time, eating a diet high in vegetables, fruits, whole grains, and olive oil can reduce heart and blood vessel disease risks.

Eating a Mediterranean-type diet won't suddenly and dramatically improve your cholesterol, magically slash your blood pressure, or help you drop 20 pounds overnight.
But if you stick with it over time, it can potentially cut your risk of heart and blood vessel diseases by as much as 25%, according to a study published online Dec. 7, 2018, by JAMA Network Open. This overall improvement may be due to the cumulative effect of numerous small positive changes that occur in the body as a result of the diet — most notably, a drop in chronic inflammation, a known risk factor for heart disease.
Stretch your exercise plan beyond weights and cardio
Including stretching exercises in your workout regimen is essential to maintaining good posture and balance.

Whether you're an avid exerciser or spend most of your time sitting in front of a computer, stretching should be part of your weekly routine. While this may conjure images of complicated twists and contortions, the type of stretching you need may be as simple as taking periodic work breaks to lift your arms above your head and to perform some other easy movements.
"Stretching doesn't have to be a particular program. It's just getting out of the posture you spend a lot of time in, taking some deep breaths, and moving your joints through their full range," says Dr. Lauren Elson, an instructor in physical medicine and rehabilitation at Harvard Medical School.
Study: Light pollution may trigger insomnia
Research we're watching
High exposure to bright, artificial outdoor lights during the night may result in sleepless nights for older adults. The more of this so-called light pollution that people were exposed to at night, the more they seemed to turn to medication to help them sleep, according to a study published in the Nov. 15, 2018, Journal of Clinical Sleep Medicine. People in brightly lit areas, as judged by satellite data, also seemed to take those drugs for longer and took higher doses than people who weren't exposed to nighttime light.
To come to their conclusions, the researchers looked at data on more than 50,000 adults ages 60 or older from the National Health Insurance Service–National Sample Cohort, a database of information collected on people who participated in health screenings between 2002 and 2013 in South Korea. Researchers compared the people's nighttime light exposure and their use of two sleep drugs, zolpidem (Ambien) and triazolam (Halcion).
