Q. How does a cold virus spread from one person to the next? And what can I do to protect myself?

A. The common cold is most often spread by direct contact with the respiratory secretions of someone who is infected, typically through hand-to-hand contact. Here is how it happens: The person with a cold touches his or her mouth or nose (we do this all day without thinking). The cold viruses are now on the person's hands. The person then touches you, such as by shaking hands. You rub your eyes, nose, or mouth, and the viruses enter your body, and so it goes.

Maintaining proper balance as you age requires attention, strength, and flexibility.

One skill that can sharply decline with age, and often with little warning, is your sense of balance.

"As people age, changes in flexibility, muscle strength and power, body sensation, reflexes, and even mental function all contribute to declining balance," says Dr. Brad Manor, associate director of the Mobility and Falls Translational Research Center with Harvard-affiliated Hebrew SeniorLife. "You need to work on all these factors to maintain a strong sense of balance."

Here are 10 ways to safeguard your life (and health) when an emergency or disaster strikes.

Natural disasters and other kinds of emergencies can strike anywhere and often with little warning. Yet, new data from the University of Michigan National Poll on Healthy Aging show that most adults ages 50 to 80 are ill-prepared for severe weather, long-term power outages, or other emergency situations.

"Older adults should take the time to focus on how they will cope and manage with an emergency," says Dr. Howard LeWine, assistant professor of medicine at Harvard Medical School and editor-in-chief of this newsletter. "A small effort now can protect their health and well-being when an emergency does occur."

Research continues to explore the possible benefits of omega-3 fish oil supplements, especially for heart health, and a recent review of existing data suggests they may protect against heart attack and coronary artery disease.

Researchers from Harvard's T.H. Chan School of Public Health and Brigham and Women's Hospital examined 13 trials, involving almost 128,000 people, to look for any association between omega-3 supplements and the risk of heart attacks, strokes, coronary artery disease, and death from cardiovascular disease. Their results were published online Sept. 30, 2019, by the Journal of the American Heart Association.

A study published online Sept. 4, 2019, by the International Journal of Cancer showed a possible connection between regular mushroom consumption and a lower risk of prostate cancer.

The researchers recruited more than 36,000 men ages 40 to 79. They recorded various health information, such as physical activity, family and medical history, and diet. Information on diet included 39 foods and beverages. The men were then followed for a period ranging from 13 to almost 25 years.

Q. I know that osteoporosis is linked to hereditary factors that I can't change. But are there things I can do to reduce my risk?

A. It's true that many risk factors for osteoporosis, such as your sex, age, and genes, are not things you can change. But there are things you can do to improve your bone health. This includes adopting a healthy diet that is rich in calcium and getting enough vitamin D, which can help maintain and improve bone health. Regular exercise can also help strengthen your bones or prevent bone loss. In particular, activities that put stress on your bones, such as jumping, running, and weight-bearing exercises, can stimulate bone cells to produce proteins that bolster bone strength. In children, these activities can actually increase bone density. While adults don't gain the same degree of benefit that kids do, exercise can still have moderate effects on bone, helping to maintain strength that might otherwise be lost. To further protect bone health, cut down on unhealthy habits, such as smoking or drinking excess amounts of alcohol. If you have risk factors for osteoporosis, you might also want to talk to your doctor about whether any of your medications might be harming your bone health.

Your money might be better spent on something else.

During the winter months, you've likely seen ads for products that claim to give your immune system a boost to help you ward off colds and the flu. But can something in a bottle, whether a vitamin formulation or probiotic, really rev up your immune system to help you stay healthy?

"Unfortunately, the reality is that those kinds of products aren't really offering you any benefit," says Michael Starnbach, a professor of microbiology at Harvard Medical School. "There's no evidence that they help in fighting disease."

Healthful protein, slowly digested carbohydrates, fruit or vegetables serve up best morning mix

As you sleep, your body is hard at work digesting yesterday's dinner. By the time you wake up, your body and brain are demanding fresh fuel. "Breaking the fast" is a key way to power up in the morning. Do it right and the benefits can last all day.

If you miss the day's first meal, notes Dr. David S. Ludwig, a nutrition expert at Harvard-affiliated Children's Hospital Boston, you may start off with an energy deficit and have to tap into your energy reserves.

Yoga promotes physical health in multiple different ways. Some of them derive from better stress management. Others come more directly from the physical movements and postures in yoga, which help promote flexibility and reduce joint pain.

Following are some of the physical benefits of yoga that have a growing body of research behind them. In addition to the conditions listed below, preliminary research also shows that yoga may help with migraines, osteoporosis, balance and mobility issues, multiple sclerosis, inflammatory bowel disease, fibromyalgia, and ADHD.

Nonprofit groups offer services that can help you age in place.

The holidays are a time of giving, but they're also a time to put yourself on the receiving list and assess whether you should be taking advantage of free health-related services offered by nonprofit organizations. Services are widely available, often regardless of income. But you might not know they exist. "Most older adults aren't introduced to support services until they're hospitalized or they work with a case manager or social worker," explains Barbara Moscowitz, a geriatric social worker at Harvard-affiliated Massachusetts General Hospital. "You don't have to wait for such an event."

What's available

On the local level, you can often find free or low-cost dental clinics, emotional support groups, meal or grocery delivery services, transportation, in-home health evaluations, exercise classes, health education classes, home evaluations for fall prevention, companion programs, caregiver respite services, or programs to help you navigate difficult chronic health conditions and their treatment.
