Science Explains: Five Key Chemical Changes in the Body When Falling in Love
Summary
Falling in love triggers key chemical changes in the brain and body, including the release of dopamine, adrenaline, oxytocin, and changes in serotonin and cortisol levels that affect behavior and emotions.
Key Points
- Falling in love activates the brain's reward system, releasing dopamine, the 'feel good' hormone.
- Adrenaline increases heart rate and natural painkiller systems reduce the sensation of physical pain.
- Increased cortisol and decreased serotonin levels cause loss of appetite and sleep in early love stages.
- Oxytocin, the 'cuddle hormone,' builds trust and attachment in progressing relationships.
