Summary: Some people walk into an event energized, while others need space to recharge. The difference is just biology. Understanding how your body reacts to dopamine can make networking feel less mysterious and more manageable. The key is to recognize how you work best, so you can show up with more clarity, confidence, and purpose.

Ever wonder why some people light up at a crowded event while others need a deep breath before walking in? The answer may be less about personality alone and more about how the brain responds to stimulation.[1]

Before the Event

Extroverts tend to approach social settings with anticipation because interaction activates the brain’s reward system, especially dopamine. That creates energy, motivation, and a sense of pleasure around engagement. Introverts, by contrast, are often more sensitive to stimulation so that the same environment can feel intense more quickly.

“Networking is more quality, and less quantity.

It’s better to form a solid connection with one

new person, than a liquid connection with ten.”

– Jarod Kintz

One useful reminder is that networking is not a numbers game. A few thoughtful conversations often matter far more than a stack of shallow introductions. For introverts especially, it can help to identify a few people in advance, learn something about them, and focus on real dialogue rather than general mingling.

During the Event

As the event begins, extroverts often grow more energized with each conversation, while introverts may start to feel overstimulated or mentally fatigued. That doesn’t mean introverts dislike people. It often means they need more space, fewer inputs, or shorter bursts of interaction to stay at their best.

Both styles bring value to an event. Extroverts contribute momentum, openness, and social energy. Introverts contribute depth, observation, and more deliberate connection.

After the Event

Once the event ends, extroverts may still be riding a social high. Introverts, however, often need quiet time to recover from too much stimulation. Reading, journaling, or simply spending time alone can help them reset.

It also helps to remember that the body reacts similarly to excitement and anxiety. A racing heart or quick breath does not always mean something is wrong. Sometimes it simply means you are stepping toward something meaningful.

The Chemistry

That difference in experience is reflected in the chemistry as well. After events, extroverts often ride a lingering dopamine high, leaving them satisfied and energized. Introverts may experience what psychologists sometimes call an “introvert hangover,” a mental and physical fatigue caused by overstimulation. To recover, they often rely on acetylcholine, a neurotransmitter associated with the body’s rest-and-digest mode.

Acetylcholine slows heart rate, lowers blood pressure, and helps restore balance and contentment. It’s released during calming activities like reading, journaling, or reflection.

Dopamine and acetylcholine reveal two different ways of moving through the same world: one fueled by outward engagement, the other by inward recovery.

The body also reacts similarly to eustress and distress, producing many of the same physical signals: rapid breathing, a racing heart, a dry mouth. The difference lies in interpretation. The mind decides whether those sensations mean fear or excitement. If your heart starts pounding before meeting someone new, it may simply be your body preparing you for a valuable moment.

Understanding these biological differences can help people navigate events more comfortably and appreciate the strengths each style brings.
