Summary

Story summary

The University of Houston and Virginia Tech found that unconscious face-touching, especially on the chin, cheeks, and nose, signals mental stress during demanding cognitive tasks.
Ten academic participants were observed over four days using thermal and visual cameras to track stress responses.
Touching multiple lower-face areas correlated strongly with stress, while facial expressions were less predictive.
The findings suggest face-touching could monitor stress in solitary work environments.
