Super-agers are individuals known to maintain peak mental prowess well into their 90s and avoid dementia and Alzheimer's disease. While genetics play a big part in super-agers' cognitive health, adopting healthy lifestyle habits also contributes, and other people might be able to improve their brain health in the same way. These habits include exercising regularly, following a plant-based diet, being social, adopting mentally challenging activities, and getting adequate sleep.

In a 2024 study, people who exercised at least twice a week (for a total of at least an hour), for 10 years were less likely to report difficulty falling asleep or sleeping for less than six hours a night compared with people who were inactive for 10 years.

A survey found that one-third of couples reported occasionally or regularly sleeping in separate rooms to accommodate a bed partner. The main motivation behind separate sleeping is to ensure both people get a good night's rest, as sleep can get disrupted by a partner's snoring, teeth grinding, thrashing, sleep schedule, and different sleeping environments. Couples should work together to ensure sleeping apart does not interfere with intimacy, such as scheduling snuggle time, taking naps together, and planning times for sexual activity.

The foundation of a healthy lifestyle consists of lasting habits like eating right, maintaining a healthy weight, exercising regularly, managing mental health, and getting routine medical and wellness exams. Even making daily, small steps toward these goals can have a significant impact. Everyday strategies include doing morning stretching, taking regular naps, breathing exercises to manage stress, caring for skin and teeth, and being social.

Home sleep tests are often the preferred approach to detect obstructive sleep apnea. They use less equipment and cost less than studies done in sleep labs. Because people get to conduct the test in their own beds, they are more comfortable than they would be in a sleep lab, and the test is more likely to capture a person's natural sleep habits. But the tests aren't always accurate. And someone with a serious chronic condition, such as heart failure or a breathing disorder, might need additional data from an in-lab study.

Sleep problems such as insomnia, sleep apnea, and periodic limb movements can disrupt sleep. A lack of sleep or fragmented sleep can prevent people from getting enough restorative deep sleep and may cause unhealthy blood pressure surges. These problems may increase the risk of cerebrovascular disease (including stroke and unrecognized silent strokes) and cognitive issues.

Cannabidiol (CBD) is an active ingredient in cannabis that is derived from the hemp plant, but it does not cause a high and is not addictive. CBD has been shown to be effective in treating conditions like pain, insomnia, and anxiety.

New guidelines for managing atrial fibrillation focus on lifestyle habits to prevent and control the disorder. One recommendation is for people to limit alcohol to one drink per day, or ideally less. Another is for people who are overweight or obese to lose weight, either by striving for a body mass index no greater than 27 or by shedding at least 10% of their body weight. The guidelines also suggest that people get three to four hours of exercise per week. And people with afib who snore should consider getting tested for sleep apnea.
