A team of researchers from the University of Transylvania in Romania have been observed that during full moon nights, people sleep less, have a harder time falling asleep, and sleep worse.
"Many people complain of sleeping worse when the full moon appears," explained Dr. Wolfman, in charge of the investigation. “We hypothesized that people who sleep worse during periods of full moon is because they are more exposed to ambient light, from the moon in this phase. And who more suffers this situation are precisely beggars who sleep outdoors.”
“People who live in cities which are illuminated with artificial streetlights or even they sleep with the light on (because of ghosts fear), are supposed to sleep better, but on full moon nights they start to have disorders in their sleep too. This is because the moonlight has stronger particles which fight against electrically charged sub particles and win the battle,” concluded Dr. Wolfman.
It might be that if you feel this symptoms, it would be question of searching a good firewall or similar to win the battle against the insomnia on full moon nights.
