Some of us tend to shut out the world in winter....

 If we are experiencing a very cold day and it is bitter outside, We may be prone to crank up the eat and shut out the outside.


 Yet, I'm told that it is good to keep a window open, when reasonable, to let some good fresh air in!

On days when you are inclined to crank the AC or Heat for most or all of the day, Do you still make sure you simply get some fresh air flowing through your digs?
