A report from The Columbus Dispatch examines a study that monitored the sleep patterns of three different groups in Tanzania, Namibia, and Bolivia.
Jerry Siegel, a professor of psychiatry at the University of California-Los Angeles, was lead researcher of a study that monitored the sleep patterns of three groups whose living conditions are similar to those of our evolutionary ancestors.
The individuals monitored in the study live in Tanzania, Namibia and Bolivia in natural environments with temperatures that follow a 24-hour cycle, Siegel said.
Most of us, with heated and air-conditioned cars, offices and homes, he said, don’t experience natural cycles of warm and cool.
“We are sort of divorced from the normal temperature cycle,” Siegel said.
