One of the greatest unsolved mysteries of the universe is the mysterious force that binds two people together.
It is an ethereal idea without a scientific basis and cannot be explained by anyone’s personal definition of love.
But Dr. Helen Fisher’s team at Rutgers University claims that distinct hormones that originate in the brain characterize the various phases of falling in love.
The three fundamental stages of falling in love are lust, attraction, and attachment.
A specific group of hormones stimulates each stage. Dopamine, norepinephrine, and serotonin help with attraction, oxytocin and vasopressin help with attachment, and testosterone and oestrogen fuel lust.
It’s not surprising that for many years, people thought that most other emotions, including love, originated in the heart.
However, according to Rutgers University researchers, love is all about the brain, which whips up the rest of your body.
Stage 1: Lust
Lust is motivated by sexual enjoyment. The hypothalamus stimulates the synthesis of testosterone and oestrogen from the testes and ovaries (a part of the brain).
Oestrogen levels peak around ovulation, whereas testosterone boosts libido.
Stage 2: Attraction
Because “attraction” influences the brain pathways that regulate “reward” behavior, the first few weeks of a relationship can be tremendously thrilling and even all-consuming.
Dopamine and norepinephrine are released during attraction, resulting in decreased appetite and sleeplessness.
Dopamine (pleasure), adrenaline (fight or flight), and norepinephrine (alertness) produce euphoria, making falling in love appear to be an addictive high.
Low serotonin levels, according to researchers, may be responsible for the decline in reaction to attraction, which impacts hunger and mood.
This may explain the infatuation that characterizes the early stages of love.
Stage 3: Attachment
Attachment is essential in long-term relationships, with oxytocin and vasopressin acting as the primary hormones, whereas lust and attraction are only present in romantic partnerships.
Oxytocin is a cuddling hormone generated by the hypothalamus that is significantly released during sex. Since we are attached to our family, it is a prologue to bonding.
