 How is REM linked with mood disturbances?


REM sleep interrupts the release of some neurotransmitters (eg norepinephrine) and this might allow the brain receptors to recover and become more sensitive to their release (more likely to react) after a break. Such neurotransmitters are likely to affect mood and learning. Being deprived may lead to mood disturbances such as grumpiness, irritability and sadness.
