Science News: “Signs of sleep debt found in the blood”

Science News reports that Signs of sleep debt found in the blood (emphasis added):

A drop in certain fats and acids in the blood may reveal whether a person is critically sleep deprived, scientists report online February 9 in Proceedings of the National Academy of Sciences. When people and rats skimp on slumber, two compounds involved in metabolism become depleted.

A reliable marker of sleep debt could be used to test whether pilots, truck drivers and other people who hold jobs with long hours are sufficiently well rested, says coauthor Amita Sehgal, a neuroscientist at the University of Pennsylvania.

WIND: the emphasis is on risky professions, but might this not be a wonderful tool for athletes in the emerging age of personalized digital medicine?
