Summary
Researchers at the University of Sussex are studying stress by measuring changes in nose temperature using thermal cameras. The study found that stress causes a drop in nose temperature due to changes in blood flow, and this could help understand and manage stress better.
Key Facts
- Scientists are using thermal cameras to study stress by filming changes in nose temperature.
- Stress causes blood flow changes, reducing nose temperature by 3-6 degrees.
- The study involved 29 volunteers who participated in stress tests.
- Participants gave speeches and performed mental arithmetic to induce stress.
- Most people recover quickly as their nose temperature returns to normal within minutes.
- The research suggests that changes in nose temperature can indicate stress levels.
- This method could help monitor stress in people unable to communicate, such as babies.
