Your hoods need the correct amount of makeup air, and your supply duct to the bathroom needs to provide a slightly lower CFM than is being removed by the bathroom exhaust fan.
I have a new home (5yrs old) and we’ve been having issues with frozen doors and locks every winter. We changed all locks, done all weatherstripping and still have frozen locks and have difficulty with doors sticking. We had hvac, home inspections done and one of them mentioned about getting the pressure inside the home checked. He also suggested storm doors to alleviate the problem of having frozen doors and locks but would that solve the issue?
I live in a very wintery climate, central British Columbia, Canada, and have never, ever had problems with frozen doors and locks. I suspect your house is running at a fairly high positive pressure, pushing moist interior air out through cracks and openings where it condenses and freezes. Yes, storm doors would help, but that's a bit of a bandaid approach. I would look into why that moist air is escaping.

Nice video!
How do you measure the difference in pressure between outside and inside?

@@paulmaxwell8851 agreed
Doesn’t Pascal scale is gives more accuracy? Roughly 3-5 pascal with door shut
How could I see pressure fluctuation in a cabin?
Or measure pressure fluctuation in a single space?
wilderness / rustic or modern build ? fireplace or mechanical hvac system ?
Check my hallways of ebbets field I do not want any decompress sickness
Was that last measurement a neg pressure???? She showed every measurement except that one and appeared surprised🤔
Nice
Very COoL. I know I feel a lot of pressure when I'm in a public bathroom. Just saying
