Love is more than a feeling — it’s a biological and psychological driver that shapes mental health, stress levels, and even physical wellbeing. In a National Geographic article, writer Daryl Austin explains how the brain is wired for connection and why bonding with others supports health across the lifespan.

Love and the Brain: What Happens When We Bond

When we experience attraction, affection, and attachment, the brain activates reward and bonding pathways that influence emotions, motivation, and safety. This process involves the limbic system and a network of chemical messengers often called the “love hormones.”

The 7 Love Hormones (and What They Do)

Austin highlights seven key hormones and neurotransmitters commonly linked to bonding and connection: oxytocin, vasopressin, dopamine, serotonin, noradrenaline, estrogen, and testosterone. Together, they support trust, attachment, desire, pleasure, and the “spark” people often feel early in relationships while also helping sustain long-term closeness over time.

Mental and Physical Health Benefits of Love

Strong relationships, romantic or platonic, are associated with meaningful health benefits. The article discusses research-linked outcomes like reduced stress, improved sleep, better immune functioning, lower pain, improved mood, and even longevity.

Why Heartbreak Hurts So Much

Loss and breakup can trigger a real mind-body stress response, including shifts in hormones that can affect appetite, sleep, anxiety, and depression symptoms. The good news: over time, the nervous system can re-stabilize, especially when people practice self-care and build supportive relationships.
