My son has been sleeping in total darkness for years. He is 19. He blacks out his windows and he sleeps a solid 8-9hrs per night. We are in the middle of moving him to his own apartment and his window treatment came down just before he went to bed last night. He decided he could deal with it for one night and just fell asleep with his window uncovered. He woke up shortly after daybreak with the most excruciating headache. He is not prone to migraines. Could this be caused by a harsh introduction to light that he is not used to?
