Stay In The Dark

Posted Jan 14 2011 3:12pm
A study, recently accepted for publication in the Journal of Clinical Endocrinology & Metabolism, suggests that exposure to light at night may increase risk for diabetes, high blood pressure and other problems. Light's impact on melatonin levels is thought to be the cause.

Exposure to electrical light between dusk and bedtime "strongly suppresses melatonin levels and may impact physiological processes regulated by melatonin signaling, such as sleepiness, thermoregulation, blood pressure, and glucose homeostasis."

So not only have researchers recently found links between light at night and cancer and depression, there is now reason to further investigate its effect on blood pressure and diabetes.

Melatonin is produced in the pineal gland of the brain in darkness. It helps regulate the sleep-wake cycle, blood pressure and body temperature.
