Most people know what it's like to be dumped by a lover. It hurts, right? Well scientists now think the sensation is more than just emotional. Love really is a pain, at least when it ends badly, they say.
The participants were also subjected to being touched by a hot probe, which was engineered to simulate the same level of pain as spilling a very hot cup of coffee on yourself.
Unsurprisingly, the lovelorn volunteers claimed looking at photos of their former partners hurt as much as being touched by the probe.
But the scientists, who scanned the volunteers' brains during the experiments, confirmed the pain wasn't just a figment of the ditched lovers' imaginations. That's because, while looking at the photographs, the scans showed increased activity in the same parts of the volunteers' brains that were active while they were being subjected to the hot probe.
In other words, the brain processes feelings of rejection in the same way as it processes physical pain.
Meanwhile, other research claims time really is the greatest healer where affairs of the heart are concerned, as brain scans of rejected lovers show decreasing activity over time in areas linked with emotional attachment.
