Teenagers and young adults who reported using pre-workout dietary supplements were more than twice as likely as non-users to say they slept five hours or less per night, according to an analysis of Canadian survey data published in the journal Sleep Epidemiology.
Researchers have found that vivid, immersive dreams can make sleep feel deeper and more restorative, even during periods of high brain activity. A study analyzing brain recordings from 44 healthy adults showed that participants reported their deepest sleep after intense dream experiences. The findings challenge traditional views of deep sleep as minimal brain activity.

A Swiss study debunks the widespread notion of spring fatigue as a myth. Researchers from the University of Basel and Inselspital Bern found no evidence of increased tiredness in spring in a year-long survey of 418 people.
A new review of studies indicates that higher dietary fibre intake could enhance sleep quality by supporting beneficial gut bacteria. Researchers found lower diversity in gut microbiomes among people with sleep disorders, particularly reduced levels of anti-inflammatory bacteria. This points to potential dietary interventions, though more research is needed to confirm causality.

Researchers have discovered that jellyfish sleep for about eight hours a day, including midday naps, much like humans. This finding in brainless marine creatures suggests sleep's benefits may be ancient and widespread. The study highlights how sleep helps repair neuronal damage in these simple animals.
Researchers have pinpointed five types of sleep patterns among young adults, each associated with specific mental health issues and brain activity differences. The study highlights how sleep disturbances, aid use, and short duration connect to cognition, emotions, and behaviors. These profiles offer new insights into sleep's broad impact on well-being.
