I don't know wether it's true or not, but I liked the red light, and my spouse too. It helps - improves mood, heals minor pain, calms you down, and warms you up. It also helps with falling taking naps if needed, I fell asleep faster. Lots of joy for $70. I found vintage Kenmore red lamp with red bulb on eBay. I find it better than LEDs, since it emits heat as well.
I use a 10,000 LUX light therapy lamp in the morning and it does wonders for my mood. When I started, colleagues commented on my better mood without knowing about the lamp (obviously). It is amazing how large of an effect light has on us.
