Yeah, Digestive system is second brain.Some experts have dubbed the digestive tract your "second brain" because it's so sensitive to your emotions.
Butterflies in your belly before giving a presentation. The burning in your chest when your boss lays a stack of work on your desk. Your stomach tied up in knots when you're stuck in traffic. Each of these physical reactions is evidence of the powerful connection between the mind and the gastrointestinal (GI) tract.he key to the complex interaction is the enteric nervous system, which experts sometimes refer to as the "brain in your gut." "Thousands of nerves line the intestines and signal muscles to contract to propel food along the digestive tract,"Like the one in your head, your gut's brain depends on neurotransmitters such as serotonin, the famous feel-good chemical.
"Around 95 percent of the body's serotonin is produced in the intestinal tract,".While the serotonin in your brain regulates mood, in the gut, it promotes the growth of nerve cells and alerts the immune system to foreign invaders like viruses and bacteria. Serotonin also keeps the two systems in constant communication, so when stress hits, it's no wonder your stomach starts to churn—or that GI problems make you depressed and anxious.
