Lack of Sleep Hormone Linked to T2D


melatoninIt’s been confirmed that lack of sleep leads to an increased risk of developing T2D. The study in the Journal of the American Medical Association confirms the correlation between less sleep hormone and a greater chance of developing T2D.

The study was designed to observe the relation between the sleep hormone, melatonin, and the risk of developing T2D. At the beginning of the study, none of the women had T2D. The study was conducted over a 12 year period.

Throughout the data gathering period, 370 women developed T2D and a control group of 370 did not develop T2D. Information was compared between the two groups of women.

The sleep hormone level, melatonin, was associated with a higher risk of developing T2D. This confirms what was found in a study investigating the interrelationship between melatonin and insulin signaling. T2D presents with an impairment in insulin signaling and the way the body uses insulin.

Although it was examined in rats, the study revealed an inverse relationship whereby an increase in melatonin levels leads to a down-regulation of insulin secretion and vice versa.

Whether you’re a mouse, a sheep, or a hardworking nurse — your melatonin levels seem to have a great influence on you glucose metabolism. Rest up and keep your glucose levels balanced.
