I see no mention of humidity controls. With the way you set up airflow, if you got chilly, it is likely the humidity went lower than 40%. This is not recommended as the sinus membranes dry out and the protection against viral infection is much reduced.

Low humidity isn’t ideal, but is still better than low ventilation given that we have to choose. Ex: outside is safer than well-humidified inside.
Also, don’t masks help with nasal humidity?
