Oxytocin - The cuddle hormone
Oxytocin is a powerful hormone released by men and women during orgasm.
It probably deepens the feelings of attachment and makes couples feel much closer to one another after they have had sex. The theory goes that the more sex a couple has, the deeper their bond becomes.
Oxytocin also seems to help cement the strong bond between mum and baby and is released during childbirth. It is also responsible for a mum’s breast automatically releasing milk at the mere sight or sound of her young baby.
Diane Witt, assistant professor of psychology from New York has showed that if you block the natural release of oxytocin in sheep and rats, they reject their own young.
Conversely, injecting oxytocin into female rats who’ve never had sex, caused them to fawn over another female’s young, nuzzling the pups and protecting them as if they were their own.
Vasopressin is another important hormone in the long-term commitment stage and is released after sex.
Vasopressin (also called anti-diuretic hormone) works with your kidneys to control thirst. Its potential role in long-term relationships was discovered when scientists looked at the prairie vole.
Prairie voles indulge in far more sex than is strictly necessary for the purposes of reproduction. They also – like humans - form fairly stable pair-bonds.
When male prairie voles were given a drug that suppresses the effect of vasopressin, the bond with their partner deteriorated immediately as they lost their devotion and failed to protect their partner from new suitors.
And finally … how to fall in love
- Find a complete stranger.
- Reveal to each other intimate details about your lives for half an hour.
- Then, stare deeply into each other’s eyes without talking for four minutes.
York psychologist, Professor Arthur Arun, has been studying why people fall in love. He asked his subjects to carry out the above 3 steps and found that many of his couples felt deeply attracted after the 34 minute experiment. Two of his subjects later got married.
