Even in an unusual year, tried-and-true strategies are still the best way to prevent illness.

Staying healthy is likely at the top of your list almost every winter. But this year, in the midst of a pandemic, it may be even more of a concern than usual. You might wonder: should you be taking special supplements to boost your immune system, or investing in cleaning devices to zap germs?

While the viral threats may be different from usual this year, the truth is that you should still be using many of the same strategies that you use in a typical year, says Michael Starnbach, a professor of microbiology at Harvard Medical School. Below are five of his top tips that can help you keep yourself and your loved ones safe.

These heavily marketed liquid meals and nutrition shakes aren't always the best option for your health. Here's what you need to look for.

Supplemental nutrition shakes and drinks can be helpful for people who struggle with a loss of appetite, have difficulty chewing, have trouble preparing balanced meals, or are recovering from surgery or an illness. But these nutrition shakes aren't magic bullets for nutrition. "The danger is that people see a lot of minerals and vitamins and think more is better," says geriatrician Dr. Suzanne Salamon, an assistant professor at Harvard Medical School. "If you use the drinks as meal substitutes that might be okay. It's not okay to eat a full meal and then drink a supplement, unless the goal is to gain weight or stop weight loss. It's too many calories."

The nutrition drinks

Supplemental nutrition drinks provide a healthy balance of protein, carbohydrate, and fat. There are hundreds of varieties that fall into two general categories.

Having your sleep interrupted by the need to urinate (the medical term is nocturia) is a common cause of sleep loss, especially among older adults. Nearly two-thirds of adults ages 55 to 84 deal with this problem at least a few nights per week.

People with mild cases may wake two times a night; in severe cases, it may be as many as five or six times. The result can be significant sleep loss and daytime fatigue.

Fear can be a helpful signal; it can bring your attention to problems—such as a balance disorder, reduced vision, or muscle weakness—that keep you from moving confidently. But fear can also undermine you. Persistent worrying about a fall, if it's unwarranted, may cause you to limit your range of motion unnecessarily and avoid activities that you're capable of. It's estimated that one-third to one-half of older adults are concerned enough about potential falls that they have begun to restrict or avoid activities that would be beneficial for their health.

How can you build your confidence? If you don't trust yourself when walking, it's important to talk with your doctor to understand the cause of the fear. Is it a sign of a health problem — perhaps a vision problem or arthritis pain — that you need to address? Do you need a hip replacement or a new pair of glasses? Or are you worried about your sense of balance?
