Atrial fibrillation (afib), an often-silent heart rhythm disorder, increases the risk of stroke. Early detection may enable people to start taking anti-clotting drugs to prevent a stroke. Current afib screening methods include asking people about afib symptoms and taking an electrocardiogram during routine check-ups. Wearable devices such as smart watches and fitness trackers can detect afib, but they aren’t yet accurate enough to be used for widespread screening.

Most types of strength training, including weight lifting, are safe and beneficial for people who take medication for high blood pressure. But lifting very heavy weights (including boxes of books or heavy furniture) should be avoided.

Enhancing food with different flavors from spices, herbs, aromatic roots, citrus juice and zest, and vinegars can help people eat less sodium, a main component of salt. Fresh herbs such as basil, cilantro, and mint can deliver flavor, fragrance, and color to foods; so can spice blends such as garam masala, za’atar, and Chinese five-spice blend. Other flavor-boosting, salt-free strategies include choosing the freshest possible foods and using appropriate cooking techniques. Reducing dietary sodium helps lower blood pressure, which reduces cardiovascular disease risk.

Adopting healthier lifestyle habits doesn’t happen at once, but is a process that happens in stages. Setbacks along the way are normal, but they provide opportunities for growth and learning.

People with a high risk for heart attacks and strokes might benefit from taking blood pressure–lowering medications, even if their blood pressure is in the normal or “high normal” range and they have no clear signs of cardiovascular disease.

The U.S. Preventive Services Task Force now recommends that people begin colon cancer screening at age 45 (instead of 50) and continue through age 75. Some evidence suggests that healthy people older than 75 may also benefit from screening.

Excess fat in the belly brings a greater risk for developing heart disease, even if one has a normal body weight, according to an American Heart Association statement published online April 22, 2021, by Circulation.

The best way to avoid shingles and long-lasting pain that may result from it is to get the shingles vaccine (Shingrix), given in two doses. The vaccine contains a protein from a dead varicella-zoster virus. The shot is 90% effective and is recommended for adults ages 50 or older, even those who have had shingles before, received an older shingles vaccine called Zostavax, or don’t recall having had chickenpox. People should avoid the vaccine if they currently have shingles, are allergic to components of the vaccine, or are pregnant or breastfeeding.

Volunteering has many benefits, enabling people to gain a sense of purpose, connect with others, and get a break from their own problems. Those benefits are associated with better health, including greater levels of physical activity, better sleep quality, a healthier diet, reduced rates of cardiovascular disease, and even longevity. A person may be able to reap many of those benefits by volunteering from home, such as doing work for a nonprofit group via computer or phone.
