A recent study conducted by psychologists at the University of Sussex has revealed an interesting correlation between stress levels and the temperature of the nose. Thermal imaging was used to monitor changes in blood flow in the face, specifically focusing on the nose, as an indication of stress levels. The researchers believe that this discovery could revolutionize stress research and provide a new way to monitor and manage stress.
During the experiment, participants were subjected to stressful tasks such as giving impromptu speeches and performing mental arithmetic in front of a panel of strangers. The researchers observed a drop in temperature in the participants’ noses as they experienced stress. This drop in temperature, also known as the “nasal dip,” is a physiological response to stress that redirects blood flow to the eyes and ears to help individuals detect potential dangers.
Lead researcher Prof Gillian Forrester explained that even individuals accustomed to stressful situations, like reporters and broadcasters, exhibit the nasal dip response when under stress. This suggests that the nasal dip could serve as a reliable indicator of changes in stress levels. The researchers believe that monitoring the recovery time from the nasal dip could provide insights into how well individuals regulate stress and potentially identify risk markers for anxiety or depression.
The use of thermal imaging to measure stress responses is not limited to humans. The researchers are exploring its application in ape sanctuaries to help improve the wellbeing of rescued primates. By analyzing the stress levels of apes through thermal imaging, researchers can better understand their emotional states and develop strategies to reduce stress and enhance their quality of life. This innovative approach highlights the interconnectedness between human mental health and the wellbeing of other primate species.
The potential of thermal imaging in stress research extends beyond human subjects, offering a new perspective on how to support the emotional needs of non-human primates. By leveraging this technology, researchers aim to provide valuable insights into the behavioral and emotional responses of primates, ultimately contributing to the welfare and happiness of these animals
