Does “h” sound, specially ひ sometimes sound more like a breathy “sh” sound, then an english “h” sound?

For listening practice I am just randomly watching some short clips in Japanese. And I noticed that sometimes an “h” sound, especially ひ sound to me like more of a breathy “sh” sound.

For example here around the 30 seconds mark: https://youtu.be/YpGQ54jrmZg?si=vSqlU9YCsx1xipTL&t=30
The woman says 「・・・メイクのコツだったりとか美容の秘訣だったりとか・・・」

And when she says 秘訣（ひけつ）I can’t help but to hear like an “sh” sound. It’s not like a full blown し but more like a breathy “sh” sound like something in between an “h” and an “sh” sound. (A little bit like the german “ch” as in Bach, Yacht, etc.. but more soft) I’m probably not making sense. Am I going crazy? Am I hearing things that are not there?
