In a story on NPR’s Morning Edition, sleep expert Amy Wolfson, a professor of psychology at the College of the Holy Cross, commented on the results of a new study which finds that 18- to 24-year-olds are increasingly turning to coffee, rather than sodas, for a caffeine boost.
While coffee has recently been connected to a number of good health effects, it contains much more caffeine than colas, and, Wolfson warned, “There are absolutely negative implications” of drinking too much of it.
Noting studies that have linked caffeine consumption to decreased REM sleep, Wolfson continued, “We know that REM sleep is needed and has positive implications for memory consolidation and learning.”
