The timing of sleep just as important as quantity
Shifting sleep cycle affects immune response, sleep quality
Washington State University

Washington State University researchers have found that the timing of an animal's sleep can be just as important as how much sleeps it gets.

Ilia Karatsoreos, an assistant professor in WSU's Department of Integrative Physiology and Neuroscience, shifted mice from their usual cycle of sleeping and waking and saw that, while they got enough sleep, it was of poorer quality. The animals also had a disrupted immune response, leaving them more open to illness.
