Storyboard Text

  • If you live in a city it's said that you can't see the Milky Way because of the amount of light pollution. And its true light pollution truly is very serious.
  • Light pollution can affect birds that are migrating and use the stars to navigate.
  • Nocturnal animals sleep during the day and are active at night. Light pollution radically alters their nighttime environment by turning night into day.
  • Artificial light at night can disrupt that cycle. Our bodies produce the hormone melatonin in response to circadian rhythm.Nighttime exposure to artificial light suppresses melatonin production.
  • Suppressing melatonin production can affect your sleep cycle.
  • Suppressing melatonin production can also affect how hard it is to fall asleep and make it hard to stay asleep.
