Sleep Quality

• Red Light PBM (Including 630 nm) for Better Sleep
  
  This review suggests that photobiomodulation with red light around 630 nm applied at night can improve sleep by boosting brain function, clearing toxins like beta-amyloid during rest, and supporting overall well-being without invasive methods.

• 633 nm and 870 nm LED Enhances Sleep in Brain Injury Patients
  
  People with long-term brain injuries from trauma who got head LED treatments at 633 nm red (practical overlap with 630nm) and 870 nm near-infrared three times a week for six weeks had better sleep patterns, less PTSD symptoms, and improved social and work skills.

• 630 nm LED Promotes Alertness Without Disrupting Sleep Hormones
  
  In a study with shift workers, wearing glasses with 630 nm red LED light for 30 minutes during night shifts improved visual performance and reaction times, with a trend toward fewer self-reported sleep disturbances, all while not affecting melatonin levels that help regulate sleep.

• 630 nm LED Improves Brain Clearance in Alzheimer's Model
  
  In mice with an Alzheimer's-like condition, 630 nm red LED light therapy reversed blockages in brain fluid flow caused by harmful proteins, potentially leading to better brain health and improved sleep by enhancing natural waste removal processes that happen during rest.

• Multi-Wavelength LED (Including 810 nm) Improves Sleep and Daytime Function
  
  In a randomized trial with 30 adults who had mild sleep troubles, wearing a neck collar emitting 660 nm, 740 nm, 810 nm, and 870 nm LED light for 25 minutes before bed every other night over 3 weeks led to better self-reported relaxation, sleep quality, feeling refreshed, and daytime energy, though objective sleep measures didn't change much.

• 810 nm LED Enhances Sleep in Dementia Patients
  
  Five people with mild to moderately severe dementia used a home device with 810 nm LED light (transcranial and intranasal) for 12 weeks, showing big improvements in thinking skills, daily function, and sleep quality, with fewer issues like wandering or anger.

• 810 nm LED Boosts Sleep Quality in Neurological Patients
  
  In a pilot study on patients with stroke and Alzheimer's, transcranial 810 nm LED therapy twice a week for a month improved overall quality of life, including better sleep, reduced headaches, and enhanced mood, as reported by patients and caregivers.

• 660 nm and 850 nm LED Improves Sleep in Shift-Work Nurses
  
  In a trial with nurses who had trouble sleeping due to shift work, using a cap that shines 660 nm red and 850 nm near-infrared LED light on the head for 30 minutes, three times a week for a month, greatly reduced insomnia symptoms and improved overall sleep quality, plus lowered depression, anxiety, and stress.

• 660 nm and 850 nm LED Reduces Sleep Need in Athletes
  
  College soccer players who got full-body LED therapy with 660 nm red and around 850 nm near-infrared light for 20 minutes a few times a week slept about 40 minutes less but showed better heart recovery signs like lower heart rate, suggesting the therapy helps them recover well even with shorter sleep.

• 850 nm LED Boosts Well-Being but Not Sleep in Mild Sleep Issues
  
  People with mild sleep problems who sat under an 850 nm near-infrared LED lamp for a few hours a day, five days a week in winter, felt better overall with less drowsiness and better mood, but it didn't directly improve their sleep quality or rhythms.

• Multi-Wavelength LED (Including Close to 850 nm) Aids Falling Asleep
  
  Adults with mild insomnia wore a neck collar with LEDs at 660 nm, 740 nm, 810 nm, and 870 nm (practical overlap with 850nm) before bed every other night for three weeks, reporting easier time falling asleep and less trouble concentrating or anxiety, though main sleep measures didn't change much.

• 633 nm and 870 nm LED Enhances Sleep in Brain Injury Patients
  
  People with long-term brain injuries from trauma who got head LED treatments at 633 nm red and 870 nm near-infrared (practical overlap with 850nm) three times a week for six weeks had better sleep patterns, less PTSD symptoms, and improved social and work skills.
