A good night's sleep may be critical for maintaining brain health says a new study. 'One night of sleep deprivation increases morning blood concentrations of two molecules - a neuronal enzyme (NSE) and calcium-binding protein S-100B - in healthy young men. These molecules are typically found in the brain. Thus their rise in blood after sleep loss may indicate that a lack of snoozing might be conducive to a loss of brain tissue' said Christian Benedict Department of Neuroscience Uppsala University Sweden. To reach the conclusion the researchers selected 15 normal-weight men. In one condition they were sleep-deprived for one
