In the nearly 10 years I have been writing this blog, I have written numerous posts on stress. I even have a Page – How to deal with stress with a number of them listed if you want to read further on it. What follows here is from the American Heart Association.
Sometimes stress can be useful. But constant stress can affect overall well-being and may even impact heart health.
When stress is short-lived, it can help with performance in meeting a major deadline, interviewing for a new job or achieving another goal. Stress and its impact on the body can also be lifesaving in the face of danger. Continue reading →
Fat is fat, right? Well, no. There is more than one kind of fat.
Visceral fat is stored in a person’s abdominal cavity and is also known as ‘active fat’ as it influences how hormones function in the body. An excess of visceral fat can, therefore, have potentially dangerous consequences. Because visceral fat is in the abdominal cavity, it is close to many vital organs, such as the pancreas, liver, and intestines.
The higher the amount of visceral fat a person stores, the more at risk they are for certain health complications, such as type 2 diabetes and heart disease.
“It’s the most wonderful time of the year.” Or is it?
Yes, the holiday season can be magical — with all of its dazzling displays of lights, parades, festive parties and fun family gatherings. But it can also be one of the most stressful times of the year, when Christmas shopping is unfinished, budgets get blown and out-of-town guests overstay their welcome.
Furman University Associate Professor of Psychology Cinnamon Stetler says it’s unrealistic to think you can eliminate all holiday stress.
Research from the lab of Mark Alkema, PhD, professor of neurobiology, sheds light on how the “flight-or-flight” response impairs long-term organism health. The study, conducted in the nematode worm, C. elegans, a common research model, was published in Nature.
When humans perceive a dangerous or stressful situation, the body releases stress hormones such as adrenalin. Adrenaline makes the heart beat faster, increases blood flow to the brain and muscles, and stimulates the body to make sugar to use for fuel. The rush of adrenaline triggers the “fight-or-flight” response which gives the person the ability to escape a predator or respond to a threat. Continue reading →
Blood pressure is like what Mark Twain said about the weather, “Everybody talks about it, but nobody does anything about it.” Well almost. I have found that blood pressure is one of those subjects that is widely and wildly misunderstood. I used to think it was like grey hair on old people. Everybody has it. I was dead wrong.
Few assumptions are more dangerous than this one: If you have high blood pressure, you know it.
Doctors refer to high blood pressure, or hypertension, as a silent killer because it rarely produces warning signs.
“When symptoms do occur, such as headache, nosebleeds or blurry vision, high blood pressure may have already reached severe and possibly life-threatening levels,” says Daniel Pohlman, MD, a primary care doctor at Rush University Medical Center. Continue reading →
People generally think of stress and anxiety as negative concepts, but while both stress and anxiety can reach unhealthy levels, psychologists have long known that both are unavoidable — and that they often play a helpful, not harmful, role in our daily lives, according to a presentation at the annual convention of the American Psychological Association.
“Many Americans now feel stressed about being stressed and anxious about being anxious. Unfortunately, by the time someone reaches out to a professional for help, stress and anxiety have already built to unhealthy levels,” said Lisa Damour, PhD, a private-practice psychologist who presented at the meeting. Damour also writes a regular column for The New York Times and is author of the book “Under Pressure: Confronting the Epidemic of Stress and Anxiety in Girls.” Continue reading →
One of the ways that our brain responds to daily stressors is by releasing a hormone called cortisol — typically, our cortisol levels peak in the morning and gradually decline throughout the day. But sometimes this system can become dysregulated, resulting in a flatter cortisol pattern that is associated with negative health outcomes. Continue reading →
Regular readers know that I am a big fan of walking. I call it the Cinderella of the exercise world because it is so unappreciated. If you want to learn a lot more about the benefits of walking – after you watch this less than five minute video – check out my Page – Why you should walk more.
I just ran across this newly-published set of guidelines for helping seniors succeed in retaining their mental function and well-being as they age. As a senior myself who has a family with a history of Alzheimer’s and dementia I found it to be on point with my own situation.
The Global Council on Brain Health (GCBH) is an independent collaborative of scientists, health professionals, scholars, and policy experts from around the world who are working in areas of brain health related to human cognition. The GCBH focuses on brain health relating to people’s ability to think and reason as they age, including aspects of memory, perception and judgment.
We believe the following suggestions will increase the chances for people to experience or optimize mental well-being. If you are already engaging in these healthy activities, continue to do so, and consider trying something new as well.
1. Take the time to develop and strengthen relationships with family and friends. For more about the brain health benefits of strong social ties, see the GCBH report, The Brain and Social Connectedness: GCBH Recommendations on Social Engagement and Brain Health.
Foll disclosure: I don’t loathe it, but I wouldn’t go out on Black Friday shopping with your money. I do know folks who get up at Midnight and plunge right in. The following is what Neuroscience News has to say about Black Friday shopping.
Summary: Researchers consider why some people enjoy the thrill of Black Friday shopping, and why others don’t. Enjoyment of the social aspects of shopping may determine whether you are a fan of the day, or not. Source: The Conversation.
If the thought of taking part in the annual ritual of Black Friday gives you cold chills rather than a rush of excitement, you’re not alone. For every avid bargain hunter who plans for the day as if training for a marathon, there’s someone else who stays home, secure in the knowledge that no one will trample them, shove them or invade their personal space just to get this season’s hottest deals.

It’s not just a lack of appreciation for bargains that drives this disconnect. Psychology research indicates that several factors determine which side of the shop-‘til-you-drop divide you land on. Some people just aren’t wired to enjoy the more social aspects of shopping.
This is perfectly in line with our mantra of eat less; move more; live longer. Besides all the health benefits of exercise on the brain and body, Harvard Health Publishing says that it also reduces stress.
How does exercise reduce stress, and can exercise really be relaxing?
Rest and relaxation. It’s such a common expression that it has become a cliche. And although rest really can be relaxing, the pat phrase causes many men to overlook the fact that exercise can also be relaxing. It’s true for most forms of physical activity as well as for specific relaxation exercises.
Exercise is a form of physical stress. Can physical stress relieve mental stress? Alexander Pope thought so: “Strength of mind is exercise, not rest.” Plato agreed: “Exercise would cure a guilty conscience.” You’ll think so, too — if you learn to apply the physical stress of exercise in a controlled, graded fashion.
As you get into shape, you’ll begin to tolerate exercise, then enjoy it
How exercise reduces stress
Aerobic exercise is key for your head, just as it is for your heart. You may not agree at first; indeed, the first steps are the hardest, and in the beginning, exercise will be more work than fun. But as you get into shape, you’ll begin to tolerate exercise, then enjoy it, and finally depend on it. Continue reading →
One of my favorite songs as a kid in the 1940’s was “Don’t fence me in.”
Here are some of the lyrics: Oh, give me land, lots of land under starry skies above
Don’t fence me in
Let me ride through the wide open country that I love
Don’t fence me in
It appears I still feel that way, particularly when it comes to exercise. Working out in the health club really turns me off.
A new report reveals that exposure to green space reduces the risk of type II diabetes, cardiovascular disease, premature death, preterm birth, stress, and high blood pressure.
People with moderate to severe mid-life anxiety may face a greater risk of dementia in later life, suggests an analysis of the available published evidence led by University College London (UCL) and University of Southampton researchers and published in BMJ Open. But as yet, it’s not clear whether treatment for anxiety could curb dementia risk, say the researchers.
“We need more research to find out what impact anxiety treatment might have on dementia risk – whether that’s through pharmacological intervention, or talking therapies or treatments based on mindfulness or meditation, which are known to help reduce anxiety,” said the study’s lead author, Dr Natalie Marchant (UCL Psychiatry).
A mounting body of evidence suggests that mental illness may be associated with dementia in older age, but it’s not clear if it represents initial (prodromal) symptoms before fully fledged disease or acts as an independent risk factor. Continue reading →
I have written numerous times about using deep breathing to combat stress. Turns out that a recent study from Brigham Young University says that exercise helps to combat negative effects of stress.
The study, newly published in the journal of Neurobiology of Learning and Memory, finds that running mitigates the negative impacts chronic stress has on the hippocampus, the part of the brain responsible for learning and memory.
“Exercise is a simple and cost-effective way to eliminate the negative impacts on memory of chronic stress,” said study senior author Jeff Edwards, associate professor of physiology and developmental biology at BYU.
“The ideal situation for improving learning and memory would be to experience no stress and to exercise,” Edwards said. “Of course, we can’t always control stress in our lives, but we can control how much we exercise. It’s empowering to know that we can combat the negative impacts of stress on our brains just by getting out and running.”
To see the paper online, click here. Ten undergraduate BYU students served as co-authors on the paper, included David Marriott, who began the project for his undergraduate honor’s thesis. First author Roxanne Miller graduated in December with her Ph.D. and the research was part of her dissertation.
“Even though we will never be able to completely remove stress from our lives, it is nice to know that we can go out and do cardiovascular exercise for 20 minutes a day to help keep the stress from overwhelming our brains,” Miller said.
