Get outside for at least 20 minutes every day for two weeks. Sun counts. Rain counts. It all counts.
Two weeks is long enough to feel the cumulative effect of daily outdoor time — the way your baseline mood shifts, the way sleep improves, the way the outside world starts to feel like a resource rather than a background. The research suggests that it takes roughly two weeks of consistent behavior to begin noticing stable changes in mood and stress response from regular nature exposure. This challenge is designed to get you to that threshold.
Every day for 14 days, get outside for at least 20 minutes. It doesn't need to be a hike or a significant activity — a walk around the block counts, sitting on the porch counts, a session at the skatepark counts. The only requirements are outside, at least 20 minutes, every day. Track each day with a simple note: where you went and one word about how you felt.
