Sleep News and Research

RSS

Sleep is a physiological behavior that is common in all animal species. It forms around one third of a human life. It is not known clearly the exact functions of sleep but it seems to be essential for survival as prolonged sleep deprivation leads to severe physical impairment followed by cognitive loss and eventually death.

Study Shows the Impact of Exposome on Serum Metabolites in Children

The combined effect of environmental exposures and unhealthy lifestyle habits can affect children's cardiometabolic health in a way that exceeds their separate effects.

Male Bonobos Found to Be More Aggressive Than Chimpanzees

Chimpanzees and bonobos are often thought to reflect two different sides of human nature-;the conflict-ready chimpanzee versus the peaceful bonobo-;but a new study publishing April 12 in the journal Current Biology shows that, within their own communities, male bonobos are more frequently aggressive than male chimpanzees.

Breathing Patterns Linked to Memory Consolidation During Sleep

How are memories consolidated during sleep? In 2021, researchers led by Dr. Thomas Schreiner, leader of the Emmy Noether junior research group at LMU's Department of Psychology, had already shown there was a direct relationship between the emergence of certain sleep-related brain activity patterns and the reactivation of memory contents during sleep.
