Sleep is the body’s time for restoration and recuperation. It’s when toxins are flushed out of the brain, tissue is repaired, muscles grow, memories are consolidated, and hormones are released. Over time, getting too little sleep or fragmented sleep impairs concentration and mood and increases the risks for many chronic diseases. It helps to try to identify and address factors that may be interrupting sleep, such as snoring bed partners, alcohol, heartburn, underlying health conditions, an uncomfortable sleeping environment, or medication side effects.

A health care proxy is a person designated to make health care decisions for someone who becomes unable to make them. The best candidate for the job is someone who knows the patient well, such as a family member or friend. The proxy needs the emotional and mental ability to make decisions based on what the patient wants, no matter the health scenario or environment, such as a hospital or long-term care facility. At the time of proxy selection, the patient should communicate his or her beliefs, values, and wishes for care.

A 2022 study involving 72,000 people suggested that those who did even 15 minutes of vigorous activity per week had a 17% lower risk of death from any cause and death from cancer, compared with people who were inactive. With about 50 minutes per week, death from any cause was reduced by 36%. The reduction in risk of death from all causes, and death from cancer, was greatest in the first 40 minutes of vigorous physical activity per week.

Certain healthy habits can fight chronic inflammation, such as eating a healthy diet, exercising regularly, getting enough sleep, maintaining good oral health, and reducing stress. If adopting all those habits seems daunting, taking little steps in their direction can help. For example, a person might eat fatty fish twice a week, since it contains omega-3 fatty acids known to reduce inflammation; or go for a quick daily walk, since exercise may increase the production of hormones that help keep inflammation in check. The combined effects of many little habits can eventually add up to keep people healthier.

Stroke survivors who take their blood pressure drugs as prescribed may be less likely to experience a serious fall compared with those who don’t take their medications on schedule.

Increasing the volume or intensity of daily physical activity helps lower a person’s risk of cardiovascular disease. Boosting both appears to lower risk even further.

Sugary drinks—the biggest source of added sugar in the American diet—have been linked to higher levels of LDL cholesterol and other unhealthy fats in the bloodstream.

Arm curls, which strengthen your biceps, can be done with dumbbells or household items such as cans of soup or water bottles.

Microvascular disease refers to problems in the network of tiny blood vessels in the heart. Doctors suspect this condition in people who have angina (chest) pain with no evidence of blockages in the heart’s larger arteries. In the most common form of microvascular disease, the inner walls of small arteries thicken, and the layer of cells closest to the blood lose their ability to expand and contract in response to the demand for increased blood flow, such as during exercise. In another form of the problem, vasospastic angina, muscles within the heart’s arteries suddenly clamp down, causing a temporary spasm that blocks blood flow to heart muscle.

Side effects from both older and newer cancer therapies can affect the heart and blood vessels, possibly causing serious, sometimes life-threatening complications. People diagnosed with any type of cancer should ask their doctor whether their planned treatment might lead to cardiovascular problems. Those ages 65 and older and anyone with risk factors for heart disease (such as high blood pressure or diabetes) may want to request a referral to a cardio-oncologist. These specialists focus on preventing and managing cardiovascular problems in people who are undergoing (or have completed) treatment for cancer.
