Did I mess up my humi?

This is exactly what I thought. I'm in Ontario Canada and it has been so cold outside that the baseboard electric heaters have been going non-stop and they suck the humidity right out of the apartment. I'm not so sure maintaining 70% humidity would be possible with it as open as it was.
