Later sleep times were associated with more self-reported minutes sitting and perceived difficulties in exercising. Circadian factors should be considered when discussing exercise participation, especially for less active adults.

The association is strongest in adults who started marijuana use before age 15, with those who began early being twice as likely to struggle with severe sleep issues.
A new study reveals that suicidal deaths are more likely to occur between midnight and 4 a.m. than during the daytime or evening, peaking at 16.27 percent between 2 a.m. and 2:59 a.m. This finding suggests that circadian factors may contribute to suicidality and highlights the importance of addressing insomnia as a potential risk factor.

The study controlled for comorbid psychiatric conditions and found that poorer subjective sleep quality was associated with reduced total cortical and regional frontal lobe gray matter volumes.
A new study reveals that obstructive sleep apnea (OSA) is highly prevalent among people with multiple sclerosis (MS), and OSA risk is a significant predictor of fatigue severity. OSA may contribute to the debilitating fatigue experienced by MS patients, and clinicians should evaluate for underlying sleep disturbances.
