Falling in Love: The Chemistry Behind the Attraction1

Here’s what happens to the body when love strikes.

1. The euphoria that envelops us when we feel attracted to someone sends a message to the limbic system, which begins a chain of events:

2. The brain releases endorphins, the feel-good chemicals that induce the “high” that draws lovers together, making them feel “destined.”

3. The glands respond, pumping out hormones like dopamine and phenylethylamine (PEA), known to induce palpitations and sweaty palms.

4. Touch receptors, activated by physical contact, tell the brain to produce oxytocin, the “cuddle chemical,” which helps lovers feel connected.
