  • Exposure to light after dark inhibits the body's ability to release melatonin, typically increasing the time it takes for a person to fall asleep and/or preventing a person from staying asleep. If a person is in red light before going to bed, he or she will typically produce more melatonin than if he or she is surrounded by, e.g., synthetic blue light, and such higher melatonin production can help the person fall asleep and stay asleep.
  • Red light is ideal for evenings because it has a low color temperature, far lower than regular sunlight.
  • a person can be immersed in red light at night without giving his or her body a jolt and altering his or her internal clock the way exposure to blue light does. If a person is having trouble sleeping and is surrounding himself or herself with unnatural blue light every night, such exposure to blue light is likely a contributing factor, and often a big factor. Exposure to natural red light in the evenings can help a peson’s body ease into its sleep cycle more naturally.
  • TBI traumatic brain injury
  • Red light therapy has been studied closely and has been found to improve sleep quality as well. In one study performed among elite female basketball players, the participants tried 14-30 minute light therapy sessions once a night for 14 nights. The short-term results showed improved sleep and the researchers found red light therapy to be a nonpharmacologic and non-invasive therapy for treating sleep disorders. Nightly urination can be another factor that adversely affects a person’s sleep.
  • a 2010 study in the Journal of Urology examined the prevalence and incidence of nocturia. The study found that for ages of from 20 to 40, 1/3 of men and up to 43% of women had at least one instance of urination nightly, abd fewer than 20% of men and women reported two or more instances of night time urination.
