Running may be a useful activity to undertake for better mental health. University of Tsukuba researchers have found that only ten minutes of moderate-intensity running increases local blood flow to the various loci in the bilateral prefrontal cortex—the part of the brain that plays an important role in controlling mood and executive functions. These findings may contribute to the development of a wider range of treatment recommendations to benefit mental health.

There’s clear evidence that physical activity has many benefits, such as the ability to improve mood, but in previous studies, cycling was often the form of exercise studied. Running, however, has always played an important role in the well-being of humans. The unique form and efficiency of human running, which includes the ability to sustain this form of exertion (i.e., by jogging as opposed to sprinting), and the evolutionary success of humans are closely linked.

Despite this fact, researchers had not yet looked closely at the effects of running on brain regions that control mood and executive functions. “Given the extent of executive control required in coordinating balance, movement, and propulsion during running, it is logical that there would be increased neuronal activation in the prefrontal cortex and that other functions in this region would benefit from this increase in brain resources,” explains Professor Hideaki Soya.

To test their hypothesis, the research team used the well-established Stroop Color–Word Test and captured data on hemodynamic changes associated with brain activity while participants were engaged in each task. For example, in one task, incongruent information is shown, i.e., the word red is written in green, and the participant must name the color rather than read out the word. To do so, the brain must process both sets of information and inhibit the extraneous information. The Stroop interference effect was quantified by the difference in response times for this task and those for a simpler version of the task—stating the names of color swatches.

The results demonstrated that, after ten minutes of moderate-intensity running, there was a significant reduction in Stroop interference effect time. Furthermore, bilateral prefrontal activation had significantly increased during the Stroop task. After running, participants reported being in a better mood. “This was supported by findings of coincident activations in the prefrontal cortical regions involved in mood regulation,” first author Chorphaka Damrongthai adds.

Given that many characteristics of the human prefrontal cortex are uniquely human, this study not only sheds light on the present benefits of running but also on the possible role that these benefits may have played in the evolutionary past of humans.

The article, “Benefit of human moderate running boosting mood and executive function coinciding with bilateral prefrontal activation,” was published in Scientific Reports.

5 Steps for women to reduce their risk of COPD

Women tend to develop COPD earlier in life than men and are more likely to have severe symptoms and be hospitalized with the disease. The good news? According to the National Heart, Lung, and Blood Institute, there are steps you can take to reduce your risk for COPD.

If you’re a woman who tries to stay healthy, you may exercise several times per week, watch what you eat and get 7-9 hours of sleep each night. But are you listening to your lungs?

Chronic obstructive pulmonary disease (COPD), a leading cause of disability and death in the United States, takes an especially heavy toll on women. You may think problems like shortness of breath, frequent coughs or wheezing are just signs of getting older, but it’s important to pay attention to these symptoms and discuss them with your doctor.

COPD is a serious lung disease that causes breathing problems and worsens over time. It has often been considered a man’s disease. Yet more women than men have been diagnosed with COPD in the past decade, and over the past 20 years more women have died from it, according to the US Centers for Disease Control and Prevention.

Women tend to develop COPD earlier in life than men and are more likely to have severe symptoms and be hospitalized with the disease. The good news? According to the National Heart, Lung, and Blood Institute, there are steps you can take to reduce your risk for COPD.

Don’t Smoke

You probably already know cigarette smoking is harmful  but did you know that women may be more vulnerable to the effects of smoking? Women who smoke tend to get COPD at younger ages and with less cigarettes smoked than men. COPD is the leading cause of death among U.S. women smokers.

If you do smoke, it’s never too late to quit.

If you thought vaping was a healthy alternative to smoking, think again. Researchers are still learning about the long-term health effects of e-cigarettes, but they may contain as many, if not more, harmful chemicals than tobacco cigarettes.

Avoid Pollutants

Among people with COPD who have never smoked, most are women. Women may be more vulnerable to indoor and outdoor air pollution. Women’s smaller lungs and airways mean the same amount of inhaled pollutants may cause more damage.

Working in places like nail salons, hair salons or dry cleaners can expose you to harmful chemicals. If you’re exposed to chemical fumes at your job, talk to your employer about ways to limit exposure. Better ventilation and wearing a mask can help.

Stay Current on Vaccines

People at risk for COPD are more likely to have serious problems resulting from some vaccine-preventable diseases. Ask a health care provider about getting vaccinated against the flu, pneumococcal disease and COVID-19.

Talk to Your Doctor About COPD

Women with COPD tend to be diagnosed later than men when the disease is more severe and treatments are less effective. If you think you could be at risk, or you are having symptoms, bring it up with your health care provider. Treatment can ease symptoms and improve your ability to exercise.

2 Steps to save a life

“By equipping people with Hands-Only CPR training, we are empowering them to spring into action if a loved one needs help, as the majority of cardiac arrests occur at home.”

Published

More than 350,000 sudden cardiac arrests occur annually outside hospital settings. However, a hands-on emergency intervention like cardiopulmonary resuscitation (CPR), especially if performed immediately, can double or triple a cardiac arrest victim’s chance of survival.

According to the American Heart Association, 70% of cardiac arrests – electrical malfunctions in the heart that cause an irregular heartbeat (arrhythmia) and disrupt the flow of blood to the brain, lungs and other organs – occur at home, but often family and friends who witness a child, spouse, parent or friend going into cardiac arrest hesitate to perform potentially lifesaving CPR for fear of making the situation worse.

“By equipping people with Hands-Only CPR training, we are empowering them to spring into action if a loved one needs help, as the majority of cardiac arrests occur at home,” said Dr. Anezi Uzendu, M.D., interventional cardiologist and American Heart Association volunteer.

As part of its Hands-Only CPR campaign, nationally supported by the Elevance Health Foundation, the American Heart Association aims to increase awareness about the importance of bystander CPR and offers these two simple steps:

1.      Call 911.
2.      Push hard and fast in the center of the chest of the individual experiencing cardiac arrest.

Using the beat of a familiar song with 100-120 beats per minute, such as “Stayin’ Alive” by the Bee Gees, can help you stay on pace with the necessary compressions.

“Being able to efficiently perform Hands-Only CPR in the moment can mean the difference between life and death, and by following these two simple steps we can increase someone’s chance of survival from cardiac arrest,” said Shantanu Agrawal, M.D., board certified emergency medicine doctor and chief health officer at Elevance Health. “As a longstanding supporter of the American Heart Association, we remain focused on working together to improve health inequities in our communities by expanding access to training and increasing the number of people who learn and feel confident performing Hands-Only CPR to save lives.”

What you eat could contribute to your menstrual cramps

Roughly 90% of adolescent girls experience menstrual pain. Most use over-the-counter medicine to manage the pain but with limited positive results. Evidence has highlighted that diets high in omega-3 fatty acids and low in processed foods, oil, and sugar reduce inflammation, a key contributor to menstrual pain.

Despite the fact that menstrual pain (dysmenorrhea) is the leading cause of school absences for adolescent girls, few girls seek treatment. An analysis of relevant studies suggests that diet may be a key contributor, specifically diets high in meat, oil, sugar, salt, and coffee, which have been shown to cause inflammation.

Roughly 90% of adolescent girls experience menstrual pain. Most use over-the-counter medicine to manage the pain but with limited positive results. Evidence has highlighted that diets high in omega-3 fatty acids and low in processed foods, oil, and sugar reduce inflammation, a key contributor to menstrual pain.

This analysis was designed to study the effect of diet on menstrual pain and identify which foods contribute to it and which can reduce it. Research was conducted through a literature review that found multiple studies that examined dietary patterns that resulted in menstrual pain. In general terms, these studies found that diets high in omega-6 fatty acids promote inflammation and foods high in omega-3 fatty acids reduce it. The muscles in the uterus contract because of prostaglandins, which are active in inflammatory responses. When measuring the Dietary Inflammatory Index, it was found that those on a vegan diet (that excluded animal fat) had the lowest rates of inflammation.

“Researching the effects of diet on menstrual pain started as a search to remedy the pain I personally experienced; I wanted to understand the science behind the association. Learning about different foods that increase and decrease inflammation, which subsequently increase or reduce menstrual pain, revealed that diet is one of the many contributors to health outcomes that is often overlooked. I am hopeful that this research can help those who menstruate reduce the pain they experience and shed light on the importance of holistic treatment options,” says Serah Sannoh, lead author of the poster presentation from Rutgers University.

“Since menstrual pain is a leading cause of school absenteeism for adolescent girls, it’s important to explore options that can minimize the pain. Something like diet modification could be a relatively simple solution that could provide substantial relief for them,” said Dr. Stephanie Faubion, NAMS medical director.
