I will say mountain biking improves my mental health. It helps me burn off stress, decreases depression and anxiety, reduces irritability, and just helps me clean out my head and all that “junk” that gets stored up…..I’m able to get a lot of things straightened out in my head while I ride. I also use the time spent riding just meditating and marveling at nature and all of God’s creation which helps me build spiritually and gain a greater connection….and that’s the largest part of my mental health improvement.
