Light at night is bad for your health, and exposure to blue light emitted by electronics and energy-efficient lightbulbs may be especially so.

Sleep problems are an all-too-common reality for most older men. They often sleep less deeply and are more easily awakened. They also are more likely to suffer from conditions that affect sleep, such as sleep apnea and restless legs syndrome. Adopting several lifestyle and behavioral changes can help men maintain a proper and healthy sleep cycle.

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.
