REM sleep paradox: Dreaming may drain the brain’s energy even as fuel supply rises
Scientists discovered a surprising energy paradox in the brain during REM sleep, the stage most closely associated with dreaming. Blood supply to the brain begins increasing even before REM starts, but neurons’ immediately available energy, measured as ATP, then drops. The finding suggests that dreaming may require such intense internal processing that neurons consume energy faster than it can be replenished.
A concise, scientifically focused explanation of how dreams affect brain energy, sleep dynamics, and mental performance. 🚆
A new study has shown that the brain consumes energy much faster than it produces it while dreaming, and this can lead to waking up tired in the morning.
Research conducted at Tohoku University in Japan has revealed new findings regarding the brain's energy use during REM sleep, when dreams occur. The study found that despite increased blood and fuel flow to the brain, there was a significant decrease in ATP levels, the primary energy source used by neurons.
A groundbreaking study conducted in Japan has unraveled the biological secret behind the mental fatigue felt after vivid and intense dreams. Scientists have found that the brain consumes cellular energy much faster than it produces it during dreaming.
Research from Tohoku University in Japan has revealed that although blood and fuel flow to the brain increase during REM sleep, neurons rapidly deplete ATP, their energy unit. In mice, the decrease in ATP despite increased blood flow beginning in the 50 seconds before REM explains post-dream fatigue.
