A 2022 study of 350,000 healthy people found no evidence that high levels of physical activity fully offset the harmful effects of a low-quality diet, or that a high-quality diet fully offsets a lack of exercise.
A 2022 study of 160,000 former smokers, followed for about 20 years, found that those who were the most diligent about living a healthy lifestyle had a 27% lower risk of dying during the study period, compared with those who didn’t live a healthy lifestyle.
The miniaturization of electronics is leading to the development of next-generation devices to monitor health. People today are using various devices (typically smart watches) to measure their heart rate, the regularity of their heart rhythm, the quality of their sleep, their body temperature, and the levels of oxygen and sugar in their blood. And scientists are working on other devices—such as a thin strip of material that is pasted onto the skin—to constantly measure blood pressure, organ function, or certain body chemicals.
Many medications can affect sleep. These include prescription drugs as well as over-the-counter remedies. For example, decongestants, certain antidepressants, or beta blockers can make it hard to fall or stay asleep, and nicotine replacement medications can cause a person to have nightmares. Strategies to avoid drug-related sleep problems include taking the medication during the day, taking a lower dose, practicing good sleep hygiene (such as going to bed and waking up at the same time each day), or switching to a new medication.
Two main types of arthritis can affect the thumb and fingers. Osteoarthritis typically affects joints in the middle or end of the fingers or the base of the thumb. Rheumatoid arthritis more often affects the fingers’ middle joints or the joints that connect the fingers to the hand. Medications can halt or slow the progression of rheumatoid arthritis. There aren’t any drugs proven to halt or slow osteoarthritis. Using a splint or brace, using assistive devices (such as a shirt buttoner), and working with a certified hand therapist can help people cope with either type of arthritis.
People with attention-deficit hyperactivity disorder, a condition marked by trouble focusing and impulsive behavior, may be more likely to have cardiovascular disease that people without the disorder.
People with certain heart conditions, including a replaced or repaired heart valve, should take antibiotics before invasive dental procedures. This helps prevent endocarditis, a serious heart infection often caused by bacteria from the mouth.
Sitting too much is bad for health. But there are ways to make time spent seated a little healthier. For example, people can keep their brains active by reading, writing, doing a hobby (such as knitting), or playing an instrument. And people can exercise while in a seated position. It’s possible to do an aerobic workout that gets the heart and lungs pumping, such as a seated dance routine or calisthenics, as well as muscle-strengthening activities or stretching exercises.
Having a dog or another pet appears to lower the risk of high blood pressure and improve blood pressure control. Pet ownership may foster positive feelings (such as decreased stress) and habits (such as daily walks) that may improve heart health. People who own dogs walk about 20 minutes more per day on average than those without dogs. Pets can help combat loneliness and social isolation, which have been linked to a higher risk of heart attack, stroke, or death from these causes.
Wintertime can pose challenges to cardiovascular health. Cold temperatures can cause arteries to narrow, which can leave people with heart disease vulnerable to angina or heart attacks, especially during physical exertion. Changes in sleep, eating, and exercise habits related to the season may also affect the heart. Crowded indoor gatherings also raise a person’s risk for respiratory infections, which can exacerbate heart disease.
