It would be lovely if we all could have access to outdoor sleeping on a regular basis. It certainly has never been built directly into our housing, though i think it could. After all buttoning up mosquito netting around an open balcony can not be hard.
The point is that we all need access to open air sleeping from time to time. We all also need to get our coffee habit under control as it does impact our sleep patterns. This is best done with exposure to outside air.
