Humans evolved outdoors. Regular exposure to natural light, green spaces, and seasonal cycles regulates circadian rhythm, lowers stress hormones, and supports immunity.
Persian gardens — the original 'paradise' — were built around water, shade, scent, and seasonal fruit. The principle remains: surround yourself with living things.
Daily practices
- Step outside within 30 minutes of waking for 5–10 minutes of natural light.
- Walk in a park, garden, or among trees at least three times per week.
- Open windows daily; keep plants in living and sleeping spaces.
- Eat with the seasons — local, fresh produce at its peak.
