If that’s how your home was designed to be that tight, it was poorly designed.

Back in the 1980s or 90s, architects and engineers tried to design and build buildings as tight and efficient as possible. They quickly discovered that such buildings made people sick. They now design buildings to exchange a proscribed amount of air every hour to prevent what you are describing from happening.

So, if your home is properly designed and built, then it’s going to “leak” enough air per hour to keep the air heathy for habitation.
