What Does 生理的に無理 Mean?

生理的 (seiri-teki) means “physiological” or “biological.” 無理 (muri) means “impossible” or “can’t do it.” Together, the phrase expresses a deep, instinctive, gut-level rejection — stronger than just disliking something.

  • あの人、生理的に無理。— I can’t stand that person (on a gut level).
  • あの匂い、生理的に無理。— That smell is unbearable to me.
  • タコス生理的に無理なんだよね。— I just can’t handle tacos (instinctively).

How Strong Is This Expression?

This phrase is quite strong. It implies that no matter how hard you try, you physically/instinctively cannot accept the thing. It is not just a mild dislike — it is visceral rejection.

生理的に無理Very strongCan’t stand it — gut-level rejection

Using 無理 in Other Contexts

無理 alone is very flexible in Japanese. Here are related uses:

  • 無理しないで。— Don’t push yourself.
  • それは無理です。— That’s impossible.
  • もう無理!— I can’t take it anymore!

Common Mistakes for English Speakers

English speakers sometimes confuse 無理 with 難しい (muzukashii — difficult). But 無理 means truly impossible or beyond your limit, while 難しい just means hard. 生理的に無理 is specifically about instinctive, physical-level intolerance.
