     Based on a new study done by the Eindhoven University of Technology, Netherlands, sleep quality can be improved by opening up windows and doors. The result is more airflow and less carbon dioxide levels.

     The study was done by Dr. Asit Kumar Mishra and his colleagues, a postdoctoral researcher in the Department of the Built Environment, on 17 healthy volunteers.

     Two conditions were measured, one of which was with an open window, with carbon dioxide levels that measured 717 ppm, and a closed door, with levels that measured 1150 ppm. Humidity, temperature and background noise were recorded, and sleep questionnaires and monitoring were done according to these conditions.

      In the end, carbon dioxide levels correlated with better and more effective sleep.

     Quote from Dr. Asit Kumar Mishra “Lower carbon dioxide levels implied better sleep depth, sleep efficiency, and lesser number of awakenings.”
