Negative Behavior in Rough Times to Significant Others Has More Impact Than Positive Behavior, Study Finds

Something to think about in balancing relationships.

Refraining from bad behavior toward a significant other during stressful life events is more important than showing positive behavior, according to a Baylor University study.

Compared with positive gestures, negative ones tend to trigger more intense and immediate responses, according to the study. And how a couple works together during trying times is associated with individual well-being as well as satisfaction with the relationship.

“When people face stressful life events, they are especially sensitive to negative behavior in their relationships, such as when a partner seems to be argumentative, overly emotional, withdrawn or fails to do something that was expected,” said researcher Keith Sanford, Ph.D., professor of psychology and neuroscience in Baylor’s College of Arts & Sciences.

“In contrast, they’re less sensitive to positive behavior — such as giving each other comfort,” he said.

The study also found that low doses of a behavior are most important, and over time, more extreme levels have less impact.

“Because people are especially sensitive to negative relationship behavior, a moderate dose may be sufficient to produce a nearly maximum effect on increasing life stress,” Sanford said. “After negative behavior reaches a certain saturation point, it appears that stress is only minimally affected by further increases in the dose of relationship problems.”

“When people face stressful life events, it’s common to experience both positive and negative behavior in their relationships,” Sanford said. “When the goal is to increase feelings of well-being and lessen stress, it may be more important to decrease negative behavior than to increase positive actions.”

Health Benefits of ASMR Found in First Study of Its Kind

ASMR provides calming and stimulating sensation with no downsides currently known. It’s worth noting that the phenomenon hasn’t been researched much yet though — there may be more positives or negatives discovered in the future. There’s still an amazing amount that isn’t scientifically known about various aspects of the human mind.

Autonomous Sensory Meridian Response (ASMR) — the relaxing ‘brain tingles’ experienced by some people in response to specific triggers, such as whispering, tapping and slow hand movements — may have benefits for both mental and physical health, according to new research.

Anti-Stress Injection of the Future? Immunization With Good Bacteria Made Rat Brains More Resilient to Stress in Study

Lots of potential implications for treating disorders or problems related to stress. Studies with rats are of course common and relevant because they share a surprising number of similarities to humans.

Immunization with beneficial bacteria can have long-lasting anti-inflammatory effects on the brain, making it more resilient to the physical and behavioral effects of stress, according to new research by University of Colorado Boulder scientists.

The findings, if replicated in clinical trials could ultimately lead to new probiotic-based immunizations to protect against posttraumatic stress disorder (PTSD) and anxiety or new treatments for depression, the authors say.

“We found that in rodents this particular bacterium, Mycobacterium vaccae, actually shifts the environment in the brain toward an anti-inflammatory state,” said lead author Matthew Frank, a senior research associate in the Department of Psychology and Neuroscience. “If you could do that in people, it could have broad implications for a number of neuroinflammatory diseases.”

Anxiety, PTSD and other stress-related mental disorders impact as many as one in four people in their lifetime. Mounting research suggests that stress-induced brain inflammation can boost risk of such disorders, in part by impacting mood-influencing neurotransmitters like norepinephrine or dopamine.

“There is a robust literature that shows if you induce an inflammatory immune response in people, they quickly show signs of depression and anxiety,” said Frank. “Just think about how you feel when you get the flu.”

Research also suggests that trauma, illness or surgery can sensitize certain regions of the brain, setting up a hair-trigger inflammatory response to subsequent stressors which can lead to mood disorders and cognitive decline.

“We found that Mycobacterium vaccae blocked those sensitizing effects of stress too, creating a lasting stress-resilient phenotype in the brain,” Frank said.

For the new study, published this week in the journal Brain, Behavior and Immunity, Frank and senior author Christopher Lowry, an associate professor in integrative physiology, set out to find out what exactly M. vaccae does in the brain.

Male rats injected with the bacterium three times, one week apart, had significantly higher levels of the anti-inflammatory protein interleukin-4 in the hippocampus — a brain region responsible for modulating cognitive function, anxiety and fear — eight days after the final injection.

Benefits to Certain Types of Dark Chocolate

Why hasn’t this been studied much before?

New research shows there might be health benefits to eating certain types of dark chocolate. Findings from two studies being presented today at the Experimental Biology 2018 annual meeting in San Diego show that consuming dark chocolate that has a high concentration of cacao (minimally 70% cacao, 30% organic cane sugar) has positive effects on stress levels, inflammation, mood, memory and immunity. While it is well known that cacao is a major source of flavonoids, this is the first time the effect has been studied in human subjects to determine how it can support cognitive, endocrine and cardiovascular health.

Lee S. Berk, DrPH, associate dean of research affairs, School of Allied Health Professions and a researcher in psychoneuroimmunology and food science from Loma Linda University, served as principal investigator on both studies.

“For years, we have looked at the influence of dark chocolate on neurological functions from the standpoint of sugar content — the more sugar, the happier we are,” Berk said. “This is the first time that we have looked at the impact of large amounts of cacao in doses as small as a regular-sized chocolate bar in humans over short or long periods of time, and are encouraged by the findings. These studies show us that the higher the concentration of cacao, the more positive the impact on cognition, memory, mood, immunity and other beneficial effects.”

The flavonoids found in cacao are extremely potent antioxidants and anti-inflammatory agents, with known mechanisms beneficial for brain and cardiovascular health.

Using Different Phone Notification Settings for Stress Reduction and Productivity Increases

An alternate approach than what’s usually used now. This is enough of a problem today to be worth posting about.

After you feel a buzz in your pocket or see a flash on your phone, your attention is already fractured.

You could pick up your phone and see if what’s called you away is something you really need to address immediately – or you could try and focus on your work, all the while wondering what you’re missing out on.

Since it can take close to 25 minutes to get back on track after a distraction, according to researchers who study productivity, this is obviously a recipe for a distracted day where not much gets done.

Fortunately, we are learning better ways to handle smartphone notifications, according to research being conducted at Duke University’s Center for Advanced Hindsight, which was presented by senior behavioural researcher Nick Fitz at a recent American Psychological Association conference.

The research was conducted in collaboration with the startup Synapse, which is incubated at the Center.

Fitz and collaborators have found that batching notifications into sets that study participants receive three times a day makes them happier, less stressed, feeling more productive, and more in control.
