napA short nap can help relieve stress and bolster the immune systems of men who slept only two hours the previous night, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM).

Lack of sleep is recognized as a public health problem. Insufficient sleep can contribute to reduced productivity as well as vehicle and industrial accidents, according to the U.S. Centers for Disease Control and Prevention.

Nearly three in 10 adults reported they slept an average of six hours or less a night, according to the National Health Interview Survey.

“Our data suggests a 30-minute nap can reverse the hormonal impact of a night of poor sleep,” said one of the JCEM study’s authors, Brice Faraut, PhD, of the Université Paris Descartes-Sorbonne Paris Cité in Paris, France. “This is the first study that found napping could restore biomarkers of neuroendocrine and immune health to normal levels.” Read the rest of this entry
