  • Duration: 7 days and nights
  • Limited to a maximum of only 7 hours sleep per night
Findings

“Exposure to short-wavelength (blue) enriched …light during the daytime is associated with:

  • Significantly less sleepiness
  • Better working memory, processing speed, and procedural learning
  • Performance speed on a PC learning task was 3.2 times faster”

*This study utilized LEDs with a colour temperature over 6000K to test the efficacy of blue enriched light. MelaGen Blue was not available at the time
