The study suggests that structured mindfulness meditation training may be a useful approach to addressing sleep problems in this population.
Research reveals that sleep plays a crucial role in removing toxic waste from the brain by increasing fluid flow and clearance of neurotoxic waste products. The glymphatic system, responsible for this process, is most active during sleep, suggesting the necessity of sleep for maintaining a healthy brain environment.
Research shows depression is a powerful predictor of nighttime sleep disturbances among stroke survivors. Sleep quality is impacted by brain lesion location and depression, with daytime sleepiness also linked to fatigue, brain damage, and female gender.
A short nap can help relieve stress and bolster the immune systems of men who slept only two hours the previous night. Napping restores biomarkers of neuroendocrine and immune health to normal levels after a night of poor sleep, suggesting a potential way to counter the damaging effects of sleep restriction.
