Dopamine, oxytocin, neural synchrony — discover what your brain is really doing when you fall in love and how neuroscience explains why some bonds last a lifetime.

Have you ever drifted into a dreamy thought of someone you recently met? You can’t explain why, but they just pop into your head. You feel a surge of joy, a slight queasiness in your stomach, and your face lights up with each playful thought of your new mate. A rush of neurochemicals stimulates this euphoric behavior.

Is this stage of love fleeting or can long-term committed relationships uphold blissful adoration?

The Stages of Modern Relationships

Whether you identify yourself as heterosexual, gay, lesbian, or bi-sexual, there are various stages to each relationship. According to research, during the initial meeting, it takes between 90 seconds and 4 minutes to decide if you want to move to dating and/or sex and not always in that particular order. During this lustful stage, testosterone and estrogen drive your behavior.

As your attraction deepens and you decide to become sexually exclusive or not, your stress response stimulates the release of the neurotransmitters; adrenaline, cortisol, dopamine, and serotonin.

Throughout this stage, your stress response is activated. Blood levels increase with adrenaline and cortisol, hormones secreted by the adrenal glands. The secretion of adrenaline and cortisol provide that rush of energy, increase in heart rate, sweaty palms, and dry mouth when you suddenly think of or startlingly bump into your new attraction.

What Neuroscience Has Added 

Recent advances in Interpersonal Neurobiology (IPNB), pioneered by Dr. Dan Siegel, reveal that our brains are literally shaped by our closest relationships. The attachment patterns formed in early childhood — secure, anxious, avoidant — are encoded in neural circuitry and predict how we show up in adult love.

Even more striking: cutting-edge hyperscanning research shows that the brains of romantic partners actually synchronize with each other. When you feel truly seen and held by your partner, your nervous systems are resonating together. This is co-regulation — and it’s as biological as a heartbeat.

“Our relationships really shape how we feel, how we think, how we remember things, how we tell the story of who we are.”  — Dr. Dan Siegel

The Good News

Attachment styles can change. Bonds can be repaired. The brain’s plasticity means that with the right support — and the courage to stay present — long-term love is not just possible. It’s neurologically wired for it.

Dopamine

The neurotransmitter, dopamine is increased with ‘love struck’ mates. Dopamine stimulates an intense rush of pleasure, triggering desire and reward. A brain on cocaine has the same effect.

“couples often show the signs of surging dopamine: increased energy, less need for sleep or food, focused attention and exquisite delight in smallest details of this novel relationship” ~ Helen Fisher

Serotonin

Serotonin plays a key role in this early stage of love. Low levels of serotonin explain those constant thoughts of your lover. According to Dr. Marazziti from the University of Pisa, blood samples of couples that claimed to be madly in love for less than six months were comparable to the blood samples of patients who have Obsessive-Compulsive Disorder.

Furthermore, newly love-struck couples often idealize their partner, magnify their assets and overlook flaws.

“It’s very common to think they have a relationship that is closer and more special than anyone else’s.” ~ Ellen Berscheid

Oxytocin

Next, a couple decides upon exclusivity, engagement, living together or marrying. The attachment of the twosome instigates the powerful hormone, oxytocin.

Oxytocin is released during childbirth and creates the bond between a mother and her child. The chemical is also secreted by both of the sexes during cuddling, hugging, and sex.

Oxytocin is important because couples that exhibit high doses of oxytocin have a strong bond and attachment that can withstand the ups and downs of life. For the release of oxytocin, it takes between 19 and 23 seconds. Thus to ensure your couplehood survives the test of time; hug, cuddle and have sex regularly.

Vasopressin

Finally, vasopressin sets the stage for long-term committed couples. The hormone is released after sex and like oxytocin creates stable bonding with your partner. Vasopressin also creates the actions of devotion and protection.

The stages of a relationship change as do the release of chemicals in the brain. The surge of dopamine in the initial lustful state creates a rush of pleasure that stimulates, even more, desire and reward. Adrenaline causes the physical reaction of sweaty palms, racing heart, and dry-mouth.

Serotonin creates those compulsive, idealizing thoughts of your partner and oxytocin makes for strong bonds. Finally, vasopressin deepens the connection and generates long-lasting love.

Therefore it is possible to love and to be in love with your partner ‘til death to us part.’ Give your loved one a 30-second hug every day to ensure your love lasts.

If your bond is broken, your trust shattered, or your connection lost, couples counseling can help to mend bonds, build trust and connection again. Email april@thecourageousself.com and let’s get started.
