Elderberry syrup or tea may help reduce the duration and severity of cold and flu symptoms. But the evidence for these benefits is uncertain, since the studies are small and most did not compare elderberry to standard treatments. Claims that elderberry products can prevent viral infections or boost immunity are unproven. Elderberry supplements appear to be relatively safe; in clinical trials, effects such as nausea, vomiting, or diarrhea were mild and rare.

Tai chi uses a series of gentle, flowing motions and slow, deep breathing to exercise the body and calm the mind. It's good for health in many ways, especially for balance, which improves as the body becomes more attuned to changes in movement. Tai chi can be practiced outdoors as well as indoors, which is helpful during winter months. To get started in a tai chi practice, it helps to take a class with an instructor who supervises practitioners' progress. Classes can be found at wellness centers and health clubs.

No evidence suggests that nicotine patches promote weight loss. Nicotine suppresses appetite but also raises health risks such as high blood pressure and narrowed arteries. People can talk to a doctor about medically supervised weight loss.

Circadian rhythms, which are hardwired into nearly every cell of the body, regulate the heart and blood vessels. Disruptions to this rhythm-from shift work, poor sleep, or unhealthy habits-can raise the risk of cardiovascular disease. For example, heart attacks are more likely to occur on Mondays than any other day of the week. That's because people tend to stay up later than usual and then sleep in the next day. On Monday morning, when they have to wake up early again for work, the change may cause subtle changes in blood pressure, hormone secretion, and metabolism that raise heart attack risk.

A 2025 study suggests that consuming higher amounts of flavonoids such as berries, apples, oranges, and black tea may promote healthier aging, particularly in women.

A 2025 study suggests that higher fitness levels may help protect people from developing atrial fibrillation.

Insufficient sleep triggers a long list of physiological and hormonal changes that contribute to heart disease. For example, a lack of sleep can cause increases in blood pressure, blood sugar, inflammation, and weight. Doctors recommend getting at least seven hours of uninterrupted sleep per night. Strategies that promote better sleep include going to bed and waking up at the same time every day, creating a healthy sleep environment, and turning off electronics an hour before bedtime.

Exercise is one of the most powerful tools for preventing heart disease and extending life. Physical activity triggers favorable changes such as making cells more sensitive to insulin and reducing inflammation. It also helps keep blood vessels supple and flexible (which supports efficient blood flow), strengthens muscles (which helps burn more calories), and remodels the heart, making it more efficient at pumping blood through the body. Together, these changes all reduce a person's chances of developing common risk factors for heart disease, including diabetes, high blood pressure, high cholesterol, and obesity.

People who are hospitalized and stay in an intensive care unit have a high risk for home falls and injuries after being discharged, according to a 2025 study. Implementing physical therapy and increasing patient awareness about medication side effects may help.

A 2025 study suggests that owning a dog or cat may help slow cognitive decline as people age.
