A hand reaches down into a sunlit lawn. Over the grass floats a line chart labelled Wellbeing, climbing steeply off the top of its own axis, annotated p less than 0.5, while a goose in reading glasses looks on from the corner.

The science is in. Go outside.

For eleven years the Touch Grass Institute has studied what happens when a human hand meets a lawn. The results are unanimous, statistically significant at the p < 0.5 level, and reached by whatever route was necessary to reach them.
Key findings

Every study we have ever run agrees with us.

We set out with an open mind and a single hypothesis: that touching grass is healthy. Two hundred and fourteen studies later, not one of them has disagreed. Several of them were about something else entirely and agreed anyway.

Critics say our sample sizes are small, our controls are missing and our conclusions do not follow from our data. We say those critics have not been outside in some time, and we have the figures to prove it.

Figure 1, a scatter plot. The horizontal axis is grass touched, in blade-seconds; the vertical axis is time spent outside, in minutes. Every dot sits on one perfectly straight line. A label reads r = 1.00, and a margin note says causation: confirmed.
Figure 1. Grass touched against time spent outdoors, r = 1.00. We take this to mean the grass is causing the outside.

Our method

Rigour, in four easy steps

Step 01

Decide the answer

Touching grass is healthy. This saves a great deal of time later.

Step 02

Go outside

Every study is conducted on a lawn, so the researchers get their dose as well. This is not a conflict of interest. It is a perk.

Step 03

Find a number

Any number. Numbers that go up are wellbeing. Numbers that go down are stress. Numbers that stay the same are resilience. No result can disprove us, which we understand is the strongest kind of hypothesis.

Step 04

Submit to the goose

Our peer reviewer is a Canada goose named Professor Honk. A paper is accepted when she does not chase the author off the lawn.

Your first dose

The lawn is open. It always was.

No appointment, no prescription, no headset. Step outside, find something green, and put a hand on it. Then come back and tell us, so it counts.
