Now, in the first study of its kind, Prof. Avi Sadeh and a team of researchers from Tel Aviv University's School of Psychological Sciences explain why interrupted sleep can be as physically detrimental as no sleep at all. In the study, published in the journal Sleep Medicine, Prof. Sadeh and his colleagues Michal Kahn, Shimrit Fridenson, Reut Lerer, and Yair Ben-Haim establish a causal link between interrupted sleep patterns and compromised cognitive abilities, shortened attention spans, and negative moods. The researchers discovered that interrupted sleep is equivalent to no more than four consecutive hours of sleep.

"The sleep of many parents is often disrupted by external sources such as a crying baby demanding care during the night. Doctors on call, who may receive several phone calls a night, also experience disruptions," said Prof. Sadeh. "These night wakings could be relatively short — only five to ten minutes — but they disrupt the natural sleep rhythm. The impact of such night wakings on an individual’s daytime alertness, mood, and cognitive abilities had never been studied. Our study is the first to demonstrate seriously deleterious cognitive and emotional effects."
