While the specific search results for 'poor' were dictionary definitions, the evidence for Claim 6 explicitly mentions that 'insufficient sleep [is] linked to a higher risk of cardiovascular disease', and general medical consensus supports the link to obesity, depression, and productivity. However, based strictly on the provided evidence snippets, the BGNES source explicitly corroborates the cardiovascular link.

Three independent web sources confirm the use of AI to analyze over 200,000 Google Street View images to identify visual neighborhood characteristics.

The claim is corroborated by multiple sources discussing the study's findings, specifically noting that highly walkable/pedestrian-friendly streetscapes were associated with shortened sleep duration.

Although the 'Evidence for claim 8' section says 'No evidence found', the actual evidence provided for Claims 2 and 7 explicitly contains this information. Euronews and the BGNES-related source both state that pedestrian-friendly/oriented layouts were associated with lower perceived safety and shorter sleep.

Euronews, BGNES, and another research summary all confirm that streets framed by buildings or trees were associated with fewer insomnia symptoms and longer sleep.

Multiple sources confirm the sample size of 1,089 working adults living on lower floors of apartments in Tokyo.

Euronews and other reports explicitly state that researchers at Osaka Metropolitan University studied employed adults aged 40-59 living on the third floor or below in Tokyo.

Multiple independent sources (Euronews, BGNES, and a third research summary) confirm that greener neighborhoods and streets with greater visual enclosure are associated with longer sleep.

Multiple sources confirm the link between greener neighborhoods, higher perceptions of safety, and longer sleep.
