Nugget of Knowledge: Biology of love


What happens when someone falls in love?

Love is a biological process that evolution has come up with to have people reproduce.

You can thank extra proteins in your bloodstream for those memories of your fantastic first date. These proteins encourage new neuron connections in your brain when you are in love. 

People in love are also happier because the brain releases more of the hormones dopamine and oxytocin, which are feel-good chemicals. 

Another hormone that a love-struck brain produces is vasopressin, which leads to possessiveness and territorial feelings. 

Higher levels of adrenaline and less seratonin make you anxious and give you the one-track mind approach.

Adrenaline and norepinephrine bring you sweaty palms, a fluttering heart and a dry mouth. 

Your autonomic nerous system, which looks after your body’s unconscious actions, is connected to what arouses you. When you see your lover, your pupils dilate. 

A 2010 study at Stanford University found that staring at photo of someone you are in love with reduces moderate pain by 40 percent.
