Low to Moderate Levels of Stress Boost Brain Functioning

A new study in Psychiatry Research indicates that low to moderate levels of stress are good for your brain. “Good” stress levels proved psychologically beneficial, acting as a kind of inoculation against mental health disorders, such as depression and antisocial behavior. They also build resilience to cope with future stressful experiences, and positively impact neurocognitive abilities, from working memory to cognitive flexibility.     Access this…

Stress Ages the Immune System

A new study from the University of Southern California indicates that stress–whether from traumatic events, work, or discrimination–speeds up aging in the immune system, which increases the risk of cancer, cardiovascular disease and infection. The researchers measured social stress levels against immune cell counts. People with the highest stress scores had significantly lower percentages of fresh disease fighters and higher percentages of worn-out white blood cells.…

“Groove Music” Significantly Increases Cognitive Abilities and Executive Function

A new study from Japanese researchers published in Scientific Reports found that listening to music with a groove (music that causes the sensation of wanting to move to the rhythm/beat) can significantly increase measures of executive function. This first study of its kind used both brain imaging and measured individual psychological responses to “groove music” and found that music with a groovy beat impacted cognitive…

Strong Link Between Even Modest Physical Activity and Lower Levels of Depression

A new metareview published in the highly-respected JAMA Psychiatry reveals that even modest exercise (less than recommended by public health guidelines) can have a major impact on mental health. Just 2.5 hours a week of brisk walking was related to a 25% lower risk of depression–and the biggest benefits were seen when moving from none to some activity (rather than moving from moderate to high…

Psilocybin Therapy Spurs Rapid, Sustained Improvement in Depression

Psychedelics have shown promise in treating diverse mental health disorders, but exactly how they rewire the mind remains a mystery. A small 2022 study from Imperial College in London provides some answers. Patients with severe depression were given either psilocybin or a popular antidepressant (escitalopram). The researchers used functional magnetic resonance imaging to measure brain activity pre-dose and three weeks after. The results were enlightening:…

Study: Sleeping with Even the Dimmest Light Raises Blood Sugar and Heart Rate

A new study from Northwestern University found that sleeping in even the dimmest light for one night (such as leaving the TV on or exposure to streetlights through a window) significantly impaired cardiometabolic function: increasing nighttime heart rate and next-morning insulin resistance. The researchers concluded that even when your eyes are closed, your brain knows that lights are on, with dim light activating the sympathetic…
