People have a 50% chance of developing at least one mental health disorder by age 75, according to some research. Among men, the most common are alcohol use disorder, depression, and anxiety disorders, with social anxiety disorder being the most prevalent of those. Many men miss the early warning signs of these disorders, or when they do, they often try to push through, which can worsen the symptoms. But identifying when they might have a problem is the first step toward seeking help.

People who are hospitalized and stay in an intensive care unit have a high risk for home falls and injuries after being discharged, according to a 2025 study. Implementing physical therapy and increasing patient awareness about medication side effects may help.

Circadian rhythms, which are hardwired into nearly every cell of the body, regulate the heart and blood vessels. Disruptions to this rhythm-from shift work, poor sleep, or unhealthy habits-can raise the risk of cardiovascular disease. For example, heart attacks are more likely to occur on Mondays than any other day of the week. That's because people tend to stay up later than usual and then sleep in the next day. On Monday morning, when they have to wake up early again for work, the change may cause subtle changes in blood pressure, hormone secretion, and metabolism that raise heart attack risk.

People who suffer from chronic insomnia are more likely to develop cognitive problems and score lower on thinking and memory tests compared with individuals without chronic insomnia, a 2025 study suggests.

An exercise routine that targets muscles in the legs and buttocks can help build the strength and stability that are essential for daily functioning. Lunges are an excellent exercise for this. Older adults can do them safely if they have sufficient leg strength to do the exercise correctly. For those who lack the necessary strength, modified versions can be done until it's possible to gradually work up to doing the full lunge. Once that is mastered, more advanced versions include the side lunge and walking lunge. Holding weights can increase the challenge.

Waking up in the middle of the night happens to women more often after age 55 due to many factors. These include diminished hormones and circadian rhythm changes. Stress, bladder changes, medications, chronic pain, and alcohol and caffeine use can also contribute. People can break the cycle of nighttime wake-ups by practicing good sleep hygiene, addressing medical issues, trying mind-body techniques such as deep breathing or meditation, and limiting caffeine, alcohol, and heavy evening meals.

A 2025 Harvard study found that people who most closely adhered to a Mediterranean or a plant-based diet had up to a 20% lower risk for chronic constipation, compared with people who followed other eating patterns.

A 2025 study found that people who had received a shingles vaccination had lower risks for stroke and various types of heart disease, including heart failure and heart attacks, compared with people who didn't receive a shingles vaccine.

Research suggests that exercise is beneficial in managing insomnia, but current guidelines don't specify which types may be most effective. A 2025 study found that yoga, tai chi, walking, and running were associated with reduced symptoms of insomnia.

Eating a plant-based diet may help people lower their risk for chronic constipation, according to a 2025 study. This effect may be due, at least in part, to the high fiber content of plant-based diets.
