A collaborative study from the University of Bath and other institutions found that regular exercise can help maintain levels of Vitamin D during winter months. Participants who engaged in a 10-week indoor exercise program experienced a less significant decline in Vitamin D levels compared to non-exercisers, regardless of body weight. Importantly, exercise preserved the active form of Vitamin D crucial for health. The findings emphasize the benefits of exercise beyond traditional measures of health, specifically during times of limited sunlight.
Researchers found that people with overweight and obesity who completed a 10-week indoor exercise programme over winter experienced significantly smaller drops in vitamin D levels compared to those who didn't exercise.
This is the first study to show that exercise alone can protect against the winter dip in vitamin D. It's a powerful reminder that we still have lots to learn about how exercise benefits our health.
Notably, exercise completely preserved the body's active form of vitamin D (1,25(OH)âDâ), which plays a key role in supporting bone health, the immune system, and various organs.
The programme involved four sessions per week: two treadmill walks, one longer steady-state bike ride, and one high-intensity interval bike session.
