Working late on a project? Why staying up all night is the worst thing you can do.
When running up against a deadline, pulling an all-nighter may seem your only option to complete a project, but a recent study published in the Swedish journal, Sleep showed that, rather than boosting productivity, staying up all night is actually harmful to your brain.
The researchers measured blood levels of certain proteins associated with brain injuries such as concussions and found protein levels were 20% higher in those who pulled all-nighters compared to when they got a full night’s rest. Although not as high as protein levels post-concussion, the study proves skimping on sleep can do real brain damage.
Dr. Ermerson Wickwire, Sleep Medicine program director at Howard County Centre for Lung and Sleep Medicine in Columbia, Maryland, and assistant professor at Johns Hopkins School of Medicine, says that while many executives have habituated to chronic sleep loss, they are losing out on key productivity benefits of sleep by depriving their brains of a nutrient just as vital as food or water.
