How sleeping improves brain injury.

A recent study has shown that for patients with serious brain injuries, there's a strong link between sleep patterns and recovery. The study reported in neurology journal was of 30 patients hospitalized for moderate to severe traumatic brain injuries found that sleep quality and brain function improved in tandem . Patients who still had low levels of consciousness and cognitive functioning would sleep for a couple of minutes and then wake up for a couple of minutes,both day and night,but when the brain recovered, the [normal] sleep-wake cycle reappeared. The results raise the possibility that patients with brain injuries might recover more quickly if hospitals took steps to restore normal sleep patterns,by using drugs and making sure patients are exposed to sunlight or its equivalent during the day and at night rest in a dark, quiet environment.
