Here's a partial list of chemicals that our bodies produce when we're falling in love.

PEA is a natural form of amphetamine. It puts us on high alert.

 Pheromones produced from DHEA create an inexplicable sense of wellbeing and comfort.

 Oxytocin has been called the cuddle hormone and it stimulates the secretion of dopamine, oestrogen and LHRH. 

This cascade of feel-good hormones and neurotransmitters is also generally accompanied by poor judgment. 

No wonder they call it crazy in love. 

When we're in love, the prefrontal cortex, where we make most of our good, rational decisions, goes into sleep mode. And the amygdala, which activates our threat response defenses, calls in sick. 

Which leaves us pretty vulnerable to take more risks.

And left alone without our normal neurological protections, we might find ourselves in dangerous and unexpected places we normally wouldn't dream of going.
