Avoid Coffee When Pregnant to Safeguard Brain Development

A mother’s coffee drinking during pregnancy can change important pathways in an infant’s developing brain, raising the risk of behavioral issues, attention difficulty and hyperactivity years later, say researchers at the University of Rochester, in New York. Analyzing thousands of brain scans of 9- and 10-year-olds, researchers found clear changes in how white matter tracks, which form connections between brain regions, were organized in children whose mothers reported consuming caffeine while pregnant. “These are sort of small effects and it’s not causing horrendous psychiatric conditions, but it is causing minimal, but noticeable behavioral issues that should make us consider long-term effects of caffeine intake during pregnancy,” says John Foxe, Ph.D., principal investigator of the university’s Adolescent Brain Cognitive Development study. Previous studies have found that a fetus does not have enough of the enzyme necessary to break down caffeine when it crosses the placenta.

Healthy Ways To Spend Time At Home
Global Brief: Natural Thinking Spending Time in Nature Increases Cognitive Performance
More of our time is spent indoors than ever before. One of the ways by which nature may improve cognitive function (i.e. the acquisition of and goal-oriented use of knowledge) is by improving memory formation and recall, specifically that of short-term or working memory, and goal-oriented or directed attention; the kind that requires focused effort. By comparing and contrasting 13 studies, a team of researchers has shed light on this complex interaction in research published in Frontiers in Psychology. The studies used the backwards digit span task, which requires participants to invert a series of numbers and repeat them back. All demonstrated significantly improved cognition in nature as compared to urban environments. The benefits of studies like this are two-fold: not only are we learning more about how the brain interacts with its environment, but also how to leverage this interaction to lead healthier, more productive and happier lives.
