Memory slips are aggravating, frustrating, and sometimes worrisome. When they happen more than they should, they can trigger fears of looming dementia or Alzheimer’s disease. But there are some treatable causes of forgetfulness.

The growing field of health and wellness coaching uses motivational techniques and positive psychology to offer people individualized support as they work to achieve their health goals.

Do you feel you have a purpose in your life — or perhaps think you will never find one? The answer could influence your overall well-being, says a recent study in the January/February 2020 issue of The Journal of Clinical Psychiatry.

Researchers asked 1,042 adults, average age 65, to fill out questionnaires about meaning in their lives, and compared their responses with data on their physical and mental well-being. Respondents who believed they had meaning in their life had better physical and mental health scores and higher cognitive function compared with those who didn't.

When it comes to preventing and treating high blood pressure, one often-overlooked strategy is managing stress. If you often find yourself tense and on-edge, try these seven ways to reduce stress.

1. Get enough sleep. Inadequate or poor-quality sleep can negatively affect your mood, mental alertness, energy level, and physical health.
2. Learn relaxation techniques. Meditation, progressive muscle relaxation, guided imagery, deep breathing exercises, and yoga are powerful relaxation techniques and stress-busters.
3. Strengthen your social network. Connect with others by taking a class, joining an organization, or participating in a support group.
4. Hone your time-management skills. The more efficiently you can juggle work and family demands, the lower your stress level.
5. Try to resolve stressful situations if you can. Don't let stressful situations fester. Hold family problem-solving sessions and use negotiation skills at home and at work.
6. Nurture yourself. Treat yourself to a massage. Truly savor an experience: for example, eat slowly and really focus on the taste and sensations of each bite. Take a walk or a nap, or listen to your favorite music.
7. Ask for help. Don't be afraid to ask for help from your spouse, friends, and neighbors. If stress and anxiety persist, talk to your doctor.

Along with these ways to reduce stress, add in a healthy lifestyle — maintaining a healthy weight, not smoking, regular exercise, and a diet that includes fruits, vegetables, whole grains, lean protein, and healthful fats — and high blood pressure could be a thing of the past.

Does stress really turn hair gray? Scientists conducted experiments that simulated stress and led to gray hair—in mice, which does not mean it’s true for humans, regardless of what you may have heard in the media.

An increasing body of research shows that dog ownership may boost heart health.

Looking to improve your heart health? You might want to think about getting a dog.

A growing body of scientific research suggests that having a canine companion is associated with number of health benefits, including improved cardiovascular health. "Numerous studies from Scandinavia, England and the United States suggest that dog owners have better health than individuals who don't own dogs. But what we really want to know is whether owning dogs produces better health or if it just means that healthier individuals are more likely to own dogs," says Dr. Dhruv Satish Kazi, a cardiologist and associate director of the Smith Center of Outcomes Research at Beth Israel Deaconess Medical Center and a member of the faculty of medicine at Harvard Medical School.

Q. I've heard a lot recently about inflammation being a health risk, but I'm not sure I really understand what it is. Can you explain?

A. When people talk about inflammation, they're actually talking about your immune system's response to a perceived injury or infection. When you're injured, this inflammation is actually a good thing. The area you injured will become red and swell as an army of beneficial white blood cells flow in to fight infection and help you heal. The same response occurs in other parts of your body when you encounter a virus or infection. But sometimes this immune response occurs when it shouldn't. It can be triggered, for example, when you are exposed to toxins, and by other causes such as chronic stress, obesity, and autoimmune disorders. In these cases, instead of moving in, healing the problem, and then returning to normal, the inflammation persists over time. It's thought that this chronic state of inflammation can lead to numerous health problems, including heart disease, arthritis, depression, Alzheimer's disease, and even cancer.

Research we're watching

A long work week may raise your blood pressure, according to a study published online Dec. 19, 2019, by Hypertension. Researchers found that among more than 3,500 Canadian workers, those who worked 49 hours a week or more were more likely to have high blood pressure than workers who were on the job fewer than 35 hours a week. Blood pressure was measured at the start and end of the five-year study as well as once midway through. Readings were taken by both a trained technician and a wearable monitoring device. Even after adjusting for other factors, the 49-hour-plus workers were 70% more likely to have a type of high blood pressure called masked hypertension (normal blood pressure readings at doctor visits but high outside of that setting) and 66% more likely to have sustained hypertension (defined as consistently high blood pressure readings both in and outside of the doctor's office). People who worked 41 to 48 hours a week also had higher blood pressure than those who worked fewer than 35 hours a week.

Long-term exposure to traffic noise has been linked to a greater risk of heart disease. New research reveals additional clues about this connection.

Researchers studied nearly 500 adults over a five-year period and gathered traffic and aircraft noise data for each person's home address. After adjusting for other factors that contribute to cardiovascular risk (including air pollution), they found that every 5-decibel increase in the average 24-hour noise level was associated with a 34% increase in heart attacks, strokes, and other serious heart-related problems.

Dopamine is a neurotransmitter involved in the body’s system for reward and pleasure. A recent trend has people avoiding stimulating activities in the belief that doing so allows the body to reset from being overstimulated, but the original idea has been misunderstood and wrongly applied.
