Some research has indicated that there are only a few slots for short term working memory, like people can only hold 6 to 7 items in their working memory. Being in the flow is like using all the slots in the working memory. Interruptions flush your short term working memory to use them to handle the interruption. It takes time to re-construct the working memory again. It is very annoying.
