The text claims that fear sharpens vision and sense of smell.

The claim that fear sharpens vision and sense of smell is partially supported by evidence. Fear triggers the fight-or-flight response, heightening senses as the body prepares to assess threats. Reliable sources indicate that fear can lead to hyper-awareness and heightened senses, such as dilated pupils for improved vision, but specific evidence regarding the enhancement of the sense of smell is lacking. No direct fact-check from expert organizations was found to completely verify or refute this claim.
