![]() Red light and the sleep quality and endurance performance of Chinese female basketball players. Red light at intensities above 10 lx alters sleep-wake behavior in mice. Blocking nocturnal blue light for insomnia: A randomized controlled trial. plosbiology/article?id=10.1371/journal.pbio.1002482 Traditionally in sleep medicine, sleep stages are REM and Non-REM (non rapid eye movement, or NREM), with the latter divided into three sub-stages (NREM stages. Melanopsin regulates both sleep-promoting and arousal-promoting responses to light. Melatonin suppression and sleepiness in children exposed to blue-enriched white LED lighting at night. Effect of color light stimulation using LED on sleep induction time. Influence of light exposure at nighttime on sleep development and body growth of preterm infants.

The researchers observed that participants exposed to their preferred light color fell asleep significantly quicker. The sleep cycle is divided into two main stages: non-rapid eye movement (non-REM) and rapid eye movement (REM). In the first experiment, participants were exposed to white light, a random color, or their self-selected preferred color. ![]() In the study, researchers ran two different experiments. Individual differencesĪnother 2017 study found evidence that individual taste may also play a role in determining which color light is best for inducing sleep. The researchers noted that light under 10 lux had no effect. One 2017 study on mice found that red light at an intensity of 10 lux or higher had the potential to induce sleep. The researchers found that after 14 days, participants who received light therapy improved their sleep quality and melatonin levels significantly compared to participants not exposed to any light. However, at this time, more research is needed to support this theory.Ī small study from 2012 examined the effect of 30 minutes of nighttime red light therapy in a group of 20 female basketball players. It’s thought that colors close to red on the light spectrum might stimulate melatonin production. Light sleep and deep sleep are similar in that they are both forms. When you’re getting enough hours of sleep, you’ll likely go through four to six sleep cycles per night. However, there’s no research backing the claim at this time. N1 and N2 sleep are thought of as light sleep while N3 and N4 are considered deep sleep. deep sleep: How long do these stages last The four stages make up a sleep cycle, which averages about 90 minutes. Since pink light is made up of a combination of red and purple light waves, it could also be beneficial - in theory. There’s also some evidence that individual preference may also play a role. Limited research of humans has suggested some evidence that red light may help stimulate sleep. However, because rodents are nocturnal and color-blind, it’s hard to draw conclusions from these studies. Up until now, most studies examining the best types of lights to stimulate sleep have been performed on rodents.
