A new study published in PLOS One found that people with an evening chronotype have poorer sleep quality, higher alcohol consumption, and act with less mindfulness than morning chronotypes. The association between chronotype and depression symptoms may be mediated by differences in mindfulness, sleep quality, and alcohol consumption.
A recent study published by the American Academy of Neurology found that increased daytime sleepiness in older women is associated with a double risk of developing dementia. The study tracked 733 female participants over five years and observed significant changes in sleep patterns, including declining nighttime sleep and increasing sl...

A first-of-its-kind study found that restrictive school policies didn't lead to lower phone and social media use among students, nor better outcomes in mental health and wellbeing. The study suggests that reducing time spent on phones is crucial, but schools must consider phone use beyond their boundaries.
Researchers discovered that non-REM sleep is crucial for strengthening emotionally linked perceptual memories, contrary to previous beliefs about REM sleep. The study found that the amygdala and cortical top-down circuitry play a key role in this process.
A systematic review and meta-analysis found that cold-water immersion can reduce stress levels within 12 hours, improve sleep quality, and boost quality of life. However, these benefits may fade after three months. Cold showers also showed promise in reducing sickness absence and improving mood.
