Total darkness allows the iris of the eye to completely relax. Eyes are the only place your nervous system is exposed to the world directly. If you are resting in a partially darkened room, cup your palms over your eyes for a while until it seems totally black. Remove your palms and keep your eyes closed. You will perceive some light or lessening of the black through your eyelids. Closing your eyes to sleep, in any illumination, does not allow complete relaxation. Always use a sleep mask or soft cap pulled over your eyes, doubled if needed, and test with palms over mask to be absolutely sure of total darkness.
Sleep Pointing North in Absolute Darkness
★★★★★
Sleeping with your head pointing North can improve the quality of your sleep. Also sleeping in absolute total darkness(no alarm clock lights, no light from the door jam) can have a huge impact on your over all health. It will allow more melatonin release by your body and for a longer period of time during the night, which is vital to living longer and healthier. This kind of sleep quality lifts your levels of attention, energy and motivation, awareness and helps keeping aging down to a minimum.
