Stress management may reduce health problems linked to stress, which include cognitive problems and a higher risk for Alzheimer's disease and dementia.

It's not uncommon to feel disorganized and forgetful when you're under a lot of stress. But over the long term, stress may actually change your brain in ways that affect your memory.

Studies in both animals and people show pretty clearly that stress can affect how the brain functions, says Dr. Kerry Ressler, chief scientific officer at McLean Hospital and professor of psychiatry at Harvard Medical School. Scientists have seen changes in how the brain processes information when people experience either real-life stress or stress manufactured in a research setting. (For the latter, researchers might challenge subjects to perform a difficult task, such as counting backward from the number 1,073 by 13s while being graded.) Either type of stress seems to interfere with cognition, attention, and memory, he says.

A regular practice can help your brain better manage stress and anxiety that can trigger depression.

Depression continues to be a major health issue for older adults. It affects about 20% of adults ages 65 and older, and regular depression can lead to higher risks for heart disease and death from illnesses. It also affects people's daily lives by making them more socially isolated and affecting cognitive function, especially memory.

In fact, a study of 1,111 people (average age 71), published online May 9, 2018, by Neurology, found that those who had greater symptoms of depression also had worse episodic memory — the ability to recall specific experiences and events.

Ask the doctors

Q. My friend was recently diagnosed with fibromyalgia, but it seems like she might be imagining her symptoms. Is fibromyalgia a real condition?

A. The short answer to your question is yes. Fibromyalgia is a real condition that affects some four million Americans. It's a chronic pain syndrome that experts believe may be caused by a malfunctioning nervous system. Researchers using magnetic resonance imaging to examine the brains of people with fibromyalgia have found abnormalities in the part of the brain that processes pain signals from the body. It appears that this part of the brain is essentially boosting the intensity of normal pain signals, potentially causing the body to feel pain without a physical cause.

The REACH method teaches how to overcome lingering bad feelings toward someone who did you wrong.

Almost everyone has experienced being wronged by someone. It could be a former co-worker, friend, or family member. But hanging on to those negative feelings can do great harm to your health.

"Forgiving a person who has wronged you is never easy, but dwelling on those events and reliving them over and over can fill your mind with negative thoughts and suppressed anger," says Dr. Tyler VanderWeele, co-director of the Initiative on Health, Religion, and Spirituality at the Harvard T.H. Chan School of Public Health. "Yet, when you learn to forgive, you are no longer trapped by the past actions of others and can finally feel free."

Take a moment to think about how you treat yourself when you make a mistake or fail to reach a goal. If you tend to beat yourself up when things go wrong, you, like most people, can use a little more self-compassion in your life.

Forgiving and nurturing yourself seem to have benefits in their own right. Strong self-compassion can even set the stage for better health, relationships, and general well-being. So far, research has revealed a number of benefits of self-compassion. Lower levels of anxiety and depression have been observed in people with higher self-compassion. Self-compassionate people recognize when they are suffering and are kind to themselves at these times, thereby lowering their own levels of related anxiety and depression.

Antidepressants aren't the only solution for depression. Research shows that exercise works as well as antidepressants for some people, although exercise alone isn't enough for someone with severe depression.

Listening to music may offer a range of benefits for cardiovascular health.

Music's capacity to evoke emotion is one reason people love listening to it so much. Whether you want to feel energized and uplifted or calm and relaxed, you can probably conjure a few examples of melodies that put you in your desired frame of mind. As it turns out, those mood-related benefits may extend to your heart.

"The beating of your heart and your fight-or-flight system are regulated by your brain. Once you understand that, it makes sense that listening to music that evokes a certain mood might affect the heart's function," says Dr. Andrew Budson, a lecturer in neurology at Harvard Medical School and chief of cognitive and behavioral neurology at the VA Boston Healthcare System.

The soothing and motivational sounds of music have far-reaching health benefits.

A favorite musical tune can stir up positive memories, boost your mood, and create a soothing, relaxing setting. But used in specific ways, music also is a valuable tool for supporting your health.

"Whether you need to relax, increase your energy, improve your thinking, or just get motivated for the day, music can provide extra support when you need it the most," says Marisabelle Diaz-Falcon, a music therapist with Harvard-affiliated Massachusetts General Hospital.

Learn what will and won't increase blood sugar levels and put your health in jeopardy.

It's essential to keep your blood sugar from spiking (rising suddenly), whether you're healthy or you're among the 122 million Americans who have diabetes or prediabetes. But with all the conflicting advice in circulation, it can be hard to figure out what foods and habits you need to avoid.

Bogus claims

On the Internet you'll find many reports of factors that purportedly increase blood sugar. Here are a few claims that you should know about because they just don't hold up.

While looking at the sunny side of life offers a lot of light moments, there may be a better path to well-being.

Optimism feels good. The expectation that positive things will happen is associated with happiness and better health, including fewer heart attacks and a lower risk for premature death. Pessimism, on the other hand, feels bad; it makes you depressed or anxious and keeps the fight-or-flight system activated, triggering chronic inflammation (which is linked to many diseases).

You might think the best way to improve your well-being is to cultivate an optimistic outlook. Think again. "Better than cultivating an artificial optimism is to see the situation and the world realistically," says Ronald Siegel, an assistant professor of psychology, part-time, at Harvard Medical School and medical editor of the Harvard Special Health Report Positive Psychology.
