Sleep Extremes Research


Sleep disruption is common in shift-workers, athletes crossing time-zones, military personnel on exercise.  Prof Walsh and Drs Oliver and Moore have conducted a series of studies investigating the effect of sleep on exercise performance, thermoregulation and immune status.  In one such study they showed that a single night’s sleep loss significantly impairs endurance performance.
