According to research I've found, red light will raise cortisol but not suppress melatonin production. Blue light does both. Don't remember which paper, but I found this one suggesting that blue light is worse than regular white light (which includes the blue spectrum) at suppressing melatonin: https://onlinelibrary.wiley.com/doi/abs/10.1034/j.1600-079X.... |
