A British scientific study, published in June 2025 in the prestigious British Journal of Sports Medicine, reveals unexpected advantages of outdoor training that go beyond traditional fitness approaches.
The large-scale study, which covered 1,120 active adults, compares two groups of athletes - one preferring indoor spaces, and the other choosing open terrains and parks. The results categorically demonstrate the superiority of outdoor workouts in terms of metabolic processes.
Experts found an impressive 35% increase in vitamin D levels among participants practicing physical activity outdoors. An additional positive effect is significantly less illness, especially respiratory infections.
Lead researcher Dr. Joel Brown emphasizes the comprehensive benefits: "Workouts in a natural environment combine physical exertion, sun exposure, and psychological stress relief".
The research team recommends 20-30 minute moderate activities twice weekly, preferably in the morning or afternoon, when sun exposure is safer. Additionally, the use of sunscreen is recommended when necessary.
The study reinforces the thesis that the natural environment offers unique opportunities for comprehensive improvement of human health, beyond standard fitness approaches.
