Researchers are defining the various functions of sleep, from how we learn to the regulation of metabolism and immunity. Insufficient sleep, a growing problem in modern society, can knock our biological clocks out of kilter, sometimes leading to chronic disease and neurodegeneration. New ways to treat troubled sleeping are being developed, and better sleep practice can help people with mood disorders.
