Your Gut: The Second Brain

Did you know your gut contains over 100 million neurons, forming what scientists call the enteric

nervous system. This network operates independently from your brain, controlling digestion

without any input from your head. It produces 95 percent of your body's serotonin, the chemical that

regulates your mood. This explains why anxiety gives you butterflies and stress causes stomach

problems. Your gut literally communicates with your brain through the vagus nerve,

sending signals that influence your emotions and decisions. Next time you trust your gut feeling,

you're actually listening to your second brain.
