Love is one of the strongest of human emotions but if you think it’s coming from the heart,
think again. Neuroscientists have discovered that love is a chemical reaction which involves the same cocktail of chemicals that are produced in the brain during addictions.
Our brain controls our feelings while falling in love. According to renowned anthropologist and love scientist Helen Fisher, love has three stages:
1. Lust: This stage is driven by sex hormones (testosterone and oestrogen). These hormones are what send us looking for a partner who matches certain predefined characteristic that we set, based on our genetic and cultural backgrounds.
2. Attraction: This stage of romantic love is controlled by dopamine and norepinephrine.
Dopamine is a neurotransmitter which stimulates desire and reward-seeking centres in the brain and triggers an intense rush of pleasure, euphoria and elation, similar to taking cocaine
Norepinephrine is similar to adrenaline – it is what makes our heart start race, cheeks flush and palms sweat when close to your loved one
These two hormones are responsible for the high level of energy, sleeplessness and obsession with the smallest details of your person of interest. At this stage, many areas of the brain shut down, such as the frontal cortex which is responsible for reasonable judgments. When judgment centres are not functioning, lovers are willing to risk everything for their relationship and indulge in risky behaviours. In this stage, love is truly blind.
3. Attachment: The chemicals released previously are normalised at this stage and love becomes less dramatic and less dangerous. Love-struck couples enter a state of tranquillity and reason. Some couples may start noticing faults in their partners, not because these faults are new but because love is less blind now.
The attachment stage is controlled by two hormones – oxytocin and vasopressin:
Oxytocin, which is the milk hormone that cements the bond between mother and her baby. It is also produced in men and women during orgasm. It enhances the bond between couples and is responsible for the intense feeling of closeness between couples. It is suggested the more sex couples have, the more affectionate they will become due to the release of oxytocin
Vasopressin is another bonding hormone which scientists believe is responsible for calmness, security and faithfulness – all essential for managing and maintaining a long-term loving rela
