Recently on my walks, I’ve been enjoying the amazing views as the leaves change color and fall off the trees. The science behind this change of scenery is equally amazing! In the spring and summer, chlorophyll, which reflects green wavelengths, dominates the leaves. In the fall, as shorter days signal a decline in chlorophyll production and its breakdown, we begin to see other pigments like carotenoids, which are always present and reflect yellow and orange wavelengths, and anthocyanins, which are often newly produced in the fall and reflect red and purple wavelengths. When trees ultimately shed their leaves, they reallocate valuable resources for winter dormancy. This beautiful scenery we are seeing is actually a survival strategy that helps the tree conserve energy.
Like trees, we also can benefit from resource partitioning and intentional rest! When trees shed their leaves, they prioritize their energy for winter survival, saving resources for when they’ll need them most. In the same way, taking time to rest allows us to be more resilient and resourceful. Trees can’t produce new growth year-round, and in the same (leaf) vein, we need to take time to renew energy and avoid burnout. So, this fall, take some inspiration from the trees and step outside for a relaxing walk, or whatever helps you rest and recharge.
