“Kuo suggests that fresh air, sunlight and a beautiful view relax us and turn off our “fight or flight” responses. “When we feel completely safe, our body devotes resources to long-term investments that lead to good health outcomes – growing, reproducing, and building the immune system,” she said.

However, Kuo adds these don’t provide elements of good health such as Vitamin D.”
