According to study author Dr. Avi Sadeh, who directs a sleep clinic at TAU, previous studies have established an association between night waking and the aforementioned negative consequences, but his is the first to establish a causal link. The sleep patterns of 61 healthy adults, 40 of which were females between the ages of 20 and 29 years old, were traced at their homes using actigraphy and sleep diaries. Participants were assessed after both a normal (control) night's sleep and after a night during which sleep was either restricted to four hours or interrupted four times over the course of eight hours in bed.</p><br clear="all"/>
