Study suggests that it could actually be a lack of REM sleep, or a lack of dreams, that causes certain health issues, reports Philly Voice.
In a new study published in the Journal of Neuroscience, researchers from Rutgers University found that regularly falling into rapid-eye-movement (REM) sleep may lead to better mental health.
In the study, people who spent more time in REM sleep had lower fear-related brain activity when given mild electric shocks the next day. Despite the suspense of being greeted with electric shocks, sleepers who had dreams were less likely to develop post-traumatic stress disorder (PTSD) when confronting scary, fearful events, the study suggests.
