At this point in time, scientists are unsure why women experience an increase in the production of interferon, but they think it might be a form of preparation for pregnancy. Such findings have led researchers to believe that men’s genetic response cannot be the same as women’s.

Previous studies have also found that two regions in our brains interact as we fall in love. The ventral tegmental area (VTA) and the caudate nucleus work to distribute the ‘feel good’ neurotransmitter dopamine across our brains. This means, as we fall for someone, we begin to crave being around them. And as we fall deeper in love, so, too does this craving. Makes sense, right?

And it’s not just falling in love that can affect our bodies. Experiencing heartbreak also has a physical impact. Experiencing intense rejection activates the areas of the brain that deal with physical pain, and research shows that our bodies are more physically sensitive when we feel rejected. We asked four women about the physical impact of their past break-ups here.
