The movie's novel concept is a creature that can only be seen and manifest in the dark. If the body is required to perform activities at the wrong biological time, it may not work at its best.Lights Out is an interesting stab at a horror movie based on a 2013 short film of the same name. The circadian system signals us to be awake and alert during the biological day and to sleep at biological night. When there is less light – like at night – our internal clock tells our brain to make more melatonin, which makes us drowsy. Since it is located just above the optic nerves, which relay information from the eyes to the brain, our internal clock receives light or darkness in our environment. Our internal clock regulates the production of melatonin, a hormone that promotes sleep. Sleep is in large part managed by our body’s internal clock.

Light is the main signal influencing circadian rhythms, turning on and off genes that control our internal clock. Your internal clockĬircadian rhythms are daily patterns of behavior produced naturally by our body that follow a roughly 24-hour cycle. Let’s explore the science behind astronaut insomnia and how NASA’s learnings could help you sleep.

After multiple astronauts reported insomnia due to constant exposure to light during International Space Station (ISS) missions, NASA began studying how light effects sleep cycles.

Have you noticed that it’s harder to fall asleep when the lights are on or if you’ve recently been staring at your phone or computer screen?
