A new study from Uppsala University, Sweden, shows that a lack of sleep is conducive to a loss of brain tissue. The findings are published in the journal Sleep. Fifteen normal-weight men participated in the study.
“We observed that a night of total sleep loss was followed by increased blood concentrations of NSE and S-100B. These brain molecules typically rise in blood during brain damage. Thus, our results indicate that a lack of sleep promotes neurodegenerative processes,” says sleep researcher Christian Benedict, who headed the study. “In conclusion, the findings of our trial indicate that a good night’s sleep is critical for maintaining brain health.”
