REM sleep paradox: dreaming may drain brain energy
Original: REM sleep paradox: Dreaming may drain the brain’s energy even as fuel supply rises
New research highlights a paradox in REM sleep: the brain's fuel supply rises during dreaming, yet energy consumption may increase even faster, leaving the brain energetically strained. The finding suggests dreams are far more metabolically costly than assumed and could reshape understanding of why sleep is restorative despite heavy brain activity.
Why now: Fresh coverage of new sleep science findings that challenge assumptions about the brain's energy use during dreaming.
