Columbia University study finds hourly 5‑minute walks boost mood and cut fatigue

Researchers at Columbia University Irving Medical Center analyzed data from 19,342 adult participants in NPR’s “Body Electric Challenge.” Participants chose to walk for five minutes every 30 minutes, 60 minutes or 120 minutes during a two‑week period. All groups reported lower fatigue and improved mood, but the 60‑minute interval offered the best balance of feasibility and effect. The hourly five‑minute walk reduced self‑reported fatigue, lifted mood, and did not impair work performance, with only modest (4‑7%) changes in engagement and a 1‑3% improvement in perceived productivity. The findings were published online in the British Journal of Sports Medicine on June 23. The authors suggest that short “movement breaks” could be incorporated into public‑health recommendations and workplace guidelines to counter the health risks of prolonged sitting.

The study notes limitations such as a predominantly white, female, highly educated sample and a short two‑week intervention, indicating further research is needed to confirm long‑term effects across broader populations.
