I’ve got a simple question for you this week – do you get nervous when you visit your dentist? If you do, he/she may be able to tell and the results may be quite painful.

This week’s insight relates to research undertaken by the International School for Advanced Studies in Trieste, Italy and is linked to how we humans can smell others’ emotions – yes, you read that correctly! Research has suggested that humans can actually pick up the smells of other people when they relate to negative emotions, so, if you’re feeling anxious, it’s possible that another human can pick this up via their nose.

That isn’t to say it is easy – or even done consciously – but it’s certainly been proven and this week I’m turning to a great article in New Scientist Magazine who quote some really interesting research from the aforementioned International School for Advanced Studies who did some research into how dentists’ performance was affected by the smell of the patient they were working on.

In the study they got 24 students to wear t-shirts, firstly in a very relaxed informal setting listening to a lecture and then separately in a very difficult and very important exam, and then put them onto mannequins. They then asked the dentists to complete a dental procedure on the mannequins and found that the dentists made more mistakes when working on the mannequins wearing the t-shirts worn in the stressful exam than when working on those wearing t-shirts worn in the lecture.

The upshot of this is that if you go to the dentist feeling anxious and worried they may pick that up and they may, unfortunately, not work as well on your teeth as they would have done if you’d been feeling calm.

You’ve been warned!
