Longer summary
Scott Alexander discusses recent research on the effects of high indoor carbon dioxide (CO2) levels on cognitive function and sleep quality. He describes how his housemates discovered high CO2 levels in their home and improved their symptoms by increasing ventilation. The post explores studies showing cognitive impairment at high CO2 levels and the potential impact on sleep quality. Scott suggests that nighttime CO2 levels in bedrooms can be particularly high and may affect sleep. He recommends simple solutions like opening windows or using certain plants to reduce CO2 levels. The post ends with a call for readers to participate in an informal experiment on nighttime air quality.
