One approach to treating bipolar disorders is manipulation of the body’s circadian rhythms. A recent review of research found that such therapies may help, often in combination with medications and psychotherapy.

Here's what to do when your mind tends to wander.

Everyone's attention can drift at times, like when you lose your concentration for a moment while doing routine tasks.

Many people shrug off these lapses in focus as "senior moments," but they might be related to a vulnerable brain process called executive function.

Chronic stress is associated with an increased risk of heart disease, heart attacks, and strokes. These strategies can help you manage it.

People often complain about stress, but it's actually a natural reaction with an essential purpose.

When the body senses danger, it starts its fight-or-flight response. Your nervous system releases hormones like adrenaline and cortisol, which jolt the body into a protective mode. Your heart pounds faster, muscles tighten, blood pressure rises, breathing quickens, and your senses sharpen.

Ask the doctors

Q. Every winter I experience mood changes. How do I know if it's seasonal affective disorder?

A. Seasonal affective disorder (SAD) is a type of depression that typically affects individuals during the winter months. Some experts believe it's triggered by a reduction in natural light, which starts in the fall and continues until the spring. Tracking your mood changes can help your doctor determine if you have the condition. People formally diagnosed with SAD experience episodes of major depression that occur in the fall and winter for at least two years. During these episodes, people may feel hopeless or worthless, have sleep problems, or experience changes in appetite or weight. They may also be irritable or anxious and lose interest in favorite activities.

Ask the doctors

Q. I have a very stressful job, and recently my blood pressure readings started going up. Could my job stress be the reason why?

A. Yes, chronic stress can affect blood pressure. Several hormones affect your heart's rhythm, including epinephrine and norepinephrine. When these hormone levels rise, your heart starts to work harder. Stress hormones can also constrict your blood vessels, causing temporary blood pressure spikes.

Research we're watching

Need another reason to quit smoking? Smoking may increase your chances of developing schizophrenia or depression, says a study published Nov. 6, 2019, in Psychological Medicine. It's long been known that people with mental illness are more likely to smoke than those without mental illness. But no one ever looked at what came first — the smoking or the mental illness. Researchers decided to find out using a database containing data from more than 462,000 people, of whom 8% were current smokers and 22% former smokers. The team found that people who smoked not only had a higher risk of developing depression and schizophrenia, but that people with either conditions were also more likely to smoke (although the association was not as strong for schizophrenia). The bottom line: Smoking may be bad not only for your lungs, but also your mind.

We've reported before that heavy drinking is tied to an increased risk for developing dementia. A Harvard-led study published online Sept. 27, 2019, by JAMA Network Open suggests that the risk is even worse if you have mild cognitive impairment (MCI). Researchers analyzed the data of more than 3,000 dementia-free adults (average age 78, some with MCI) who reported their alcohol use and underwent psychological testing for six years. People with MCI who drank heavily (more than 14 drinks per week) had a 72% higher risk for dementia than people who drank less than one drink per week. However, people without MCI who drank moderately (seven to 14 drinks per week) didn't appear to have an increased risk for dementia, and even seemed to have a 37% lower risk for dementia compared with people who consumed less than one drink per week. The bottom line: "Our results suggest that moderation is the healthiest approach if you drink. And if you have mild cognitive impairment, you may want to reconsider drinking alcohol at all," says Dr. Kenneth Mukamal, a study author and researcher with the Harvard T.H. Chan School of Public Health.

Want something simple to boost your health? Try looking on the bright side. A large observational study published online Sept. 27, 2019, by JAMA Network Open tied optimism to fewer heart attacks and a lower risk for premature death. Researchers combed through 15 studies that included almost 230,000 people who were followed for an average of 14 years. Being optimistic was associated with a 35% lower risk for cardiovascular events and a 14% lower risk for an early death, compared with being pessimistic. The findings don't prove that seeing the glass half-full causes better health, but many other studies have reported similar findings. "Optimistic people may have healthier habits, such as regular exercise and healthy diets; and they may be better at regulating their emotions in stressful situations, which could also contribute to lower levels of inflammation. But we need more research to confirm it," says Dr. Laura Kubzansky, a study author and co-director of the Lee Kum Sheung Center for Health and Happiness at the Harvard T.H. Chan School of Public Health.
