Results showed that after four hours of sleep per night the sleep deprivation period, they metabolized glucose least efficiently. Levels of cortisol a stress hormone were also higher during sleep deprivation periods, which has been linked to memory impairment, age related insulin resistance, and impaired recovery in athletes. Van Cauter said that after only one week of sleep restriction, young, healthy males had glucose levels that were no longer normal and showed a rapid deterioration of the body's functions. This reduced ability of the body to manage glucose is similar to those found in the elderly.
