Nature Dose (20-Minute Prescription)

What is Nature Dose (20-Minute Prescription)?

Spend 20 minutes in nature, 3x per week. That's the dose at which cortisol drops maximally. Not hiking, not exercising — just BEING in a natural setting. Doctors in the UK, Japan, and Canada now prescribe nature as medicine.

Is there evidence for it?

How do you do Nature Dose (20-Minute Prescription)?

1. 1.Find any natural setting: park, garden, riverbank, forest, beach. Urban parks count — you don't need wilderness
2. 2.Spend 20 minutes minimum. Sit on a bench, walk slowly, or just stand and observe. The key is immersion without distraction — phone stays in pocket
3. 3.Engage your senses: what do you hear? Birds, wind, water, leaves. What do you see? Light through trees, patterns in bark, clouds moving. What do you smell? Earth, flowers, rain
4. 4.Do this 3x per week for optimal cortisol reduction. A 2019 study (Frontiers in Psychology) found that 20-30 minutes, 3x per week produced the steepest cortisol decline
5. 5.No phone, no podcast, no audiobook. Just you and the trees. The mental benefits come from your attention being captured by nature (what psychologists call 'soft fascination') — screens block this
