Ventilating Churches to Prevent Sunday Headaches
—In general, churches are not properly ventilated. The chronic “Sunday headache” is by no means a myth, nor an ingenious excuse for those who are not lovers of the sanctuary. The usual custom is to close the church doors and windows—if by good fortune the latter have been open at all—as soon as the throng of worshipers have passed the threshold. Then the vitiated air is left to cool and settle near the floor. On Saturday, or an hour or two before the morning service on Sunday, the doors and windows are opened for a little while, but not long enough to change the atmosphere. A far more effectual method is to air the house thoroughly when the services of the day are ended, at which time the cooler out-door air will more quickly displace that within. And a second ventilation is also useful.
