Over the course of history it has been artists, poets and playwrights who have made the greatest progress in humanity's understanding of love.
But these days scientists are challenging that notion, and they have rather a lot to say about how and why people love each other.
In lust, it’s all about hormones, especially testosterone. But the attraction, love-struck “I can’t eat or sleep” phase, is controlled by chemicals. They are called monoamines.
Serotonin gives you the feeling that you are walking on a cloud. Dopamine gives you that feeling of pursuit and reward. By the way, chocolate can give you the same dopamine-rush. And norepinephrine, or adrenalin, is the cause of your “pounding-skipping a beat” heart and your racing pulse.
The long-term relationship isn’t without its own chemical connection either. Oxytocin is at play in both orgasms and childbirth.
Vasopressin is another important chemical in the long-term commitment stage. It is an important controller of the kidney and its role in long-term relationships was discovered when scientists looked at the prairie vole.
However, we have always known that love is a special sort of chemistry. Scientists are now beginning to show how true this is.
