Sleep deprivation has been linked to insulin resistance – a primary cause of type 2 diabetes – in several studies. Now, new research has uncovered a biological reason for this association in men: hormonal imbalance.
Previous studies have shown that sleep deprivation lowers testosterone levels and raises cortisol levels in men, which can lead to insulin resistance, a condition in which the body does not produce or use insulin properly. According to researchers at the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center in Torrance, California, controlling the balance between these two hormones helps reduce the effects of sleep loss on insulin resistance.
This research was presented on March 18th at the Endocrine Society's annual meeting in Chicago.
