Resolve Arguments the Same Day for a Happier, Healthier Life

Either sidestepping an argument or resolving it on the same day pays off quickly by halving the reactivity level—negative “aftertaste”—that day and often erasing any darkened emotional response the following day, say University of Oregon researchers. Based on surveys of more than 2,000 people reporting their emotional ups and downs during an eight-day period, the researchers found that when people feel they have resolved an argument, the emotional response associated with that disagreement is significantly reduced or even eliminated. Stress reactivity has been found to significantly reduce lifespan, studies show, and is linked to heart disease, a weakened immune system, reproductive issues and gastrointestinal conditions.

Nix Sweeteners to Avoid Spreading Antibiotic Resistance

Four widely used artificial sweeteners—saccharine, sucralose, aspartame and acesulfame potassium—promote the transfer of antibiotic resistance genes in both environmental and clinical settings, report researchers at the University of Queensland, Australia, in The ISME Journal. They found that these four nonnutritive sweeteners promote horizontal transfer of the genes between bacteria, furthering the spread of antibiotic-resistant genes in the intestine. The researchers say the findings provide insight into the spread of antimicrobial resistance and point to a potential risk associated with ingesting the artificial sweeteners.

Refrain from Spanking to Avoid Harming Young Brains

About half of U.S. parents spank their children on occasion, and a third have reported having done so in the previous week, although numerous studies have found that corporal punishment is linked to mental health issues, anxiety, depression, behavioral problems and substance abuse in children. A new Harvard study has further clarified the harm with a finding that spanking alters children’s brain development. The scientists tested 147 children ages 10 and 11 that had been spanked and used MRI to measure their neurological responses to photos of people with angry or neutral faces. Compared to peers that had not been spanked, the children had greater activation in multiple regions of the prefrontal cortex region of the brain to angry faces—a fearful response similar to that of abused children. Those areas of the brain respond to environmental cues that could be consequential, such as a threat, and may affect decision-making and processing of situations. “While we might not conceptualize corporal punishment to be a form of violence, in terms of how a child’s brain responds, it’s not all that different than abuse,” says senior researcher Katie A. McLaughlin. “It’s more a difference of degree than of type.”

Improve Sleep with a Weighted Blanket

Weighted blankets that provide a cozy, swaddled feeling have been big sellers during the trying days of the pandemic, and a new study verifies that they do provide mental health benefits. Researchers from Sweden’s Karolinska ketut-subiyanto/Pexels.com University tested 120 patients with depression, bipolar disorder, anxiety disorder or attention deficit hyperactivity disorder for four weeks. They found that a weighted blanked led to better sleep and reduced fatigue, depression and anxiety, and increased levels of daytime activity. Weighted blankets are comforters with tiny pellets or metal chains woven throughout so that weight is distributed across the body; researchers recommend using a blanket that is about 10 percent of a person’s body weight.
