How Falling in Love Affects Your Body and Brain

Sparks, butterflies, fireworks, being in love is one of the best feelings in the world. But did you know it also causes changes to your body? Here's a look at how it affects you from the inside out.

It's date night. The two of you have great chemistry. Well, that's more than just a figure of speech. The chemistry is happening in your brain.

Feel good chemicals, like dopamine, light up your brain's reward system. You may get sweaty palms, a racing heart, or a flushed face. Levels of another brain chemical called serotonin drop and that may boost your feelings of infatuation.

Your brain also powers down a series of connected nerves that transmit negative feelings like judgment. On top of all that, your adrenal glands make more of the stress hormone cortisol. Because after all, who says a new relationship is a little stressful?
