Use Glass Baby Bottles to Avoid Microplastic Particles

Polypropylene baby bottles­—which comprise 82 percent of the global baby bottle market—release an “extraordinary” number of microplastic particles, reports a new study by Trinity College Dublin. In a study published in Nature Food, which covered 48 regions worldwide, researchers found that flexible plastic baby bottles release as many as 16.2 million particles per liter. “A study last year by the World Health Organization estimated adults would consume between 300 and 600 microplastics a day—our average values were on the order of a million or millions,” study co-author John Boland told The Guardian. He called for more studies to understand the implications, saying the researchers were “absolutely gobsmacked” by the numbers. The microplastics are released when heated liquid is used to sterilize the bottles and to dissolve powdered formula and when the bottle is shaken to dissolve the powder. The higher the water temperature, the greater the release of particles. Polypropylene bottles have a “5” on the recycling symbol on the bottom.

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.
