The book goes into more detail on the impact to sleep and it wasn’t so much impacting the quantity of sleep but the quality.

Without giving too much of the book away, it was more about the type of sleep you get and the impact over time.

I think the impact over time is the key with a lot of things. You can do a lot of things once in a while and it won’t do any real harm but they can be harmful if you keep it up over an extended period of time.
