Voices in Your Head: Wearing Headphones Changes Listening

Voices in Your Head: Wearing Headphones Changes ListeningFRIDAY, Feb. 25, 2022 (HealthDay News) -- Headphones have a much greater impact on listeners than external speakers because they put voices "inside your head," a new study explains."Headphones produce a phenomenon called in-head localization, which makes the speaker sound as if they're inside your head," said study co-author On Amir, a professor of marketing at the University of California, San Diego. "Consequently, listeners perceive the communicators as closer — both physically and socially. As a result, listeners perceive the communicator as warmer, they feel and behave more empathically toward them and they are more easily persuaded by them," Amir explained in a university news release.The findings could have significant implications for training programs, remote work and...

Researchers Map Out Enormous Human Family Tree

Researchers Map Out Enormous Human Family TreeFRIDAY, Feb. 25, 2022 (HealthDay News) -- A massive genetic family tree traces the ancestry of all people today.The researchers who created it said it shows how individuals worldwide are related to one another and reveals key events in human evolution, including the migration out of Africa."Essentially, we are reconstructing the genomes of our ancestors and using them to form a vast network of relationships," said study leader Anthony Wilder Wohns. He is a postdoctoral researcher at the Broad Institute of MIT and Harvard University in Cambridge, Mass. "We can then estimate when and where these ancestors lived. The power of our approach is that it makes very few assumptions about the underlying data and can also include both modern and ancient DNA samples," Wohns explained.Wohns did the...

Dogs Feel Grief When Canine Companion Dies

Dogs Feel Grief When Canine Companion DiesTHURSDAY, Feb. 24, 2022 (HealthDay News) -- Anyone who has more than one dog might have seen it unfold: A beloved pet dies, and the remaining dog seems to suffer as deeply as the rest of the family.Now, new Italian research adds to evidence that man's best friend does indeed mourn such a loss. Eighty-six percent of 426 dog owners who had lost one of their animals said their surviving dog went on to display negative behavioral changes for months. Those changes included playing and eating less, sleeping more, becoming more fearful, and tending to whine and bark more often.But does this all add up to canine grief?"Overall, demonstration of grief in non-human animals is one of the biggest challenges facing science," acknowledged study author Dr. Federica Pirrone. She's a lecturer of...

Getting Rid of Meat in Your Diet May Lower Cancer Risk

Getting Rid of Meat in Your Diet May Lower Cancer RiskTHURSDAY, Feb. 24, 2022 (HealthDay News) -- People who go meat-free, or at least put limits on it, may have lower risks of some of the most common cancers, a new, large study suggests.British researchers stressed that their findings do not prove definitively that vegetarian/vegan diets cut people's cancer risks. In fact, there was evidence that body weight may explain some of the benefits.But the findings, based on more than 470,000 people, do strengthen the case that no-meat and low-meat diets are at least associated with lower cancer risks.They also suggest that the relationship varies depending on the type of cancer, said lead researcher Cody Watling, of the University of Oxford.One finding reinforced what past research has shown: Less meat was related to a lower risk of colon...

A Hotter Climate Could Trigger More Mental Health Crises

A Hotter Climate Could Trigger More Mental Health CrisesTHURSDAY, Feb. 24, 2022 (HealthDay News) -- Extreme heat from climate change is making it harder for people with mental illness and drug addiction to cope and adding to pressure on pandemic-stretched U.S. emergency rooms.During these severe summer temperature spikes, Americans with depression, anxiety, mood disorders and drug addiction are increasingly flocking to hospital ERs for help, a new study finds."Increasing temperatures and rates of emergency department visits for mental health [are] at an unprecedented scale across the U.S.," said lead researcher Amruta Nori-Sarma, an assistant professor of environmental health at Boston University School of Public Health.The heat itself isn't causing these conditions, she noted, but it is making it harder for people with these conditions to...

Four-Legged Friends Could Be Friend to Your Brain

Four-Legged Friends Could Be Friend to Your Brain THURSDAY, Feb. 24, 2022 (HealthDay News) -- Add better brain health to the growing list of protections your beloved pet may provide you: New research suggests that older adults with a furry companion showed slower mental declines than those without one."Prior studies have suggested that the human-animal bond may have health benefits like decreasing blood pressure and stress," said study author Dr. Tiffany Braley, from the University of Michigan Medical Center, in Ann Arbor. "Our results suggest pet ownership may also be protective against cognitive [thinking] decline."Because "stress can negatively affect cognitive function, the potential stress-buffering effects of pet ownership could provide a plausible reason for our findings," Braley said in a news release from the American...

AHA News: Understanding `Black Fatigue` – And How to Overcome ItTHURSDAY, Feb. 24, 2022 (American Heart Association News) -- Before she gave the feeling a name, Mary-Frances Winters felt it constantly. She calls it "a dull droning sound that is always present" and "an underlying syndrome of sorts that permeates my very being."It's the exhaustion born of "the day-to-day small acts of aggression, or small acts of disrespect" a Black person endures; the endless need to prove your worth; and the constant exposure to news about injustice and violence being inflicted on people who look like you.She calls the feeling "Black fatigue." And though the problem is not of their making, for the sake of their health, Black people need to understand and acknowledge the toll of living with racism, said Winters, a diversity and equity consultant from North Carolina....
