Scott Alexander reports on a survey about nighttime ventilation interventions, finding modest overall improvements but some individual success stories. Longer summary

Scott Alexander presents the results of a survey on nighttime ventilation conducted after his previous post on carbon dioxide levels. The survey, with 129 participants, explored various interventions to improve sleep quality by reducing CO2 levels. While the overall results were modest, with an average improvement of 1.4 on a 0-5 scale, some participants reported significant benefits. The most common intervention was sleeping with an open window. Despite the underwhelming results, most participants planned to continue their interventions. Scott concludes that the results are essentially negative, both for nighttime ventilation and for the reliability of informal blog surveys in producing confident data. Shorter summary
