Humans can see up to 200,000 shades of green, compared to 100,000 shades of red 👁🌿 For most of human history, we lived in forests and wild places and being able to detect shades of green was necessary for our survival. Though it is no longer an evolutionary advantage, our brains are still wired for it. Looking at green can lower stress, ease mental fatigue, and boost mood. #naturetherapy #mentalhealth #forest
