How is melatonin regulated in people who are blind? Quirks Question
This week's Quirks Question comes to us from Reed Poynter in Langley, BC, who asks:
"As a totally blind person with detached retinas, how is my melatonin level regulated? If, for me, the lights are always out, as it were, why am I not always sleeping? What research has been done in this area?"
To answer this question, we reached Dr. Parveen Bhatti, a Canadian native epidemiologist now working at the Fred Hutchinson Cancer Research Center in Seattle.
