According to research presented at the APSS annual meeting in Baltimore in June a single night of light exposure during sleep may acutely affect insulin resistance.
Even healthy adults who slept with an overhead light on had significantly greater insulin resistance the next morning.
These results are given added significance given the increasingly widespread use of artificial light exposure, especially at night.
Recall my previous comments about the adverse effects of a dysmetabolic states, such as diabetes are associated with an increased risk of dementing illness and Parkinson's later in life, not to mention end organ disease: brain, nerve, eyes, kidneys, etc.
