Nature can give attention a different place to land.

The broader attention research is mixed

A 2016 systematic review examined 31 studies of real natural environments. Its pooled analyses found benefits on three attention measures, while ten other analyses did not show clear benefits. The authors noted small samples, varied methods, and uncertainty about which parts of attention may change.

A later review found small-to-moderate improvements in some working-memory and cognitive-flexibility measures after nature exposure. It also found that results depended on how the exposure and tests were designed. Real outdoor exposure cannot be treated as proof that a screen-based experience has the same effect.

What the ADHD studies actually tested

In one small controlled study, 17 children ages 7–12 with ADHD completed a short concentration task after a 20-minute park walk and after walks in two urban settings. Scores were better after the park walk. That was an immediate result from outdoor walks—not a study of virtual nature, sound masking, or Biomi.

A 2024 systematic review found seven eligible studies about nature exposure and ADHD in school-aged children. The studies used different methods and populations. This is a reason to keep studying the question, not evidence that an app treats ADHD. Biomi is not an ADHD treatment and has not been tested as one.

How this informs Biomi

We use this research as a design prompt: offer a coherent place, gentle details, and room for a person to choose where to look. We do not promise to restore attention, drown out ADHD, or change a diagnosis. People’s needs and responses differ.
