Love is confusing. People in the U.S. Google the word “love” about 1.2 million times a month. Roughly a quarter of those searches ask “what is love” or request a “definition of love.”
What is all this confusion about?
Neuroscience tells us that love is caused by certain chemicals in the brain. For example, when you meet someone special, the hormones dopamine and norepinephrine can trigger a reward response that makes you want to see this person again. Like tasting chocolate, you want more.
Your feelings are the result of these chemical reactions. Around a crush or best friend, you probably feel something like excitement, attraction, joy and affection. You light up when they walk into the room. Over time, you might feel comfort and trust. Love between a parent and child feels different, often some combination of affection and care.
