The Journal of Neuroscience shared findings in a recent study which underscores the need for people seeking business success in high-stakes professions and circumstances not to shortchange themselves on sleep.
“When functioning correctly, the brain finds the sweet spot on the mood spectrum. But the sleep-deprived brain will swing to both extremes, neither of which is optimal for making wise decisions,” says Matthew Walker, associate professor of psychology and neuroscience at the University of California, Berkeley and lead author of the study.
The Journal of Neuroscience says: "Appropriate interpretation of pleasurable, rewarding experiences favors decisions that enhance survival." What I gather from this is that sleep deprivation makes a person temporarily feel good.
