"Lights Out" is a great book that talks extensively about how light affects our hormones and how critical sleep is to our immune system and all the restorative functions of our organs and cells, every night (as I type here at 10:40 pm when I should be in bed...) Anyway, the "Bucky" products makes a wonderful sleep mask that completely blocks light, and it's very comfortable on the face, with a little padding at the bottom so you don't feel any weight over your eyes.
Here's a bit from the book:
"Early sleep is usually REM sleep...drifting into even deeper NREM sleep as your melatonin surges shifts your brain activity to immune maintenance.
All reproductive activity is slowed at night. That means a better chance for pregnancy would be offered by daytime mating. At night, sex steroid hormones take a backseat to increased prolactin production from the pituitary. Both prolactin and melatonin are powerful players in reproduction, too, due to the simple fact the melatonin controls the production of estrogen and testosterone and prolactin makes milk. Melatonin and progesterone are both master-switch hormonal controllers...Because of melatoniin, any increase or decrease in dark time triggers physiologic and behavioral changes via sex hormones in many species, like changes in molting, breeding, and migration. Seasonal distribution of conception and birth rates in humans supports the theory that the function of melatonin is to regulate the time of readiness for reproduction. Readiness for reproduction, in turn, determines the amount and timing of progesterone release in women and dihydrotestoterone secretion in men."
