A bioRxiv preprint reports that seven days of partial sleep deprivation progressively reduced spontaneous neuronal activity in the live mouse hippocampus while tissue oxygen levels rose. After seven days of recovery, activity had not returned to baseline and oxygenation continued to increase.

A study of 95,559 UK Biobank participants found that accelerometer-estimated REM sleep was associated with lower incidence of 83 diseases. The observational analysis also found that estimated minimum-risk sleep duration for most of the conditions with non-linear associations fell between 6 and 8 hours.

A medRxiv preprint reports that repeated odour cues delivered during sleep improved PTSD symptoms and accelerated treatment response when paired with 12 weeks of trauma-focused psychotherapy. The findings combine a mechanistic study in healthy participants with a randomized clinical trial.
