How to Get Started

STEP 1
THE PHENOMENON (2 minutes)
  1. When you blush, your face turns red
  2. But same thing happens to your stomach lining!
  3. Emotions trigger blood vessel dilation throughout body
  4. Not just face - entire digestive system responds
  5. This is visible during medical procedures (endoscopy)
  6. Doctors can see stomach 'blush' during emotional moments
STEP 2
THE MECHANISM (3 minutes)
  1. Emotional response activates autonomic nervous system
  2. Releases chemicals (adrenaline, histamine)
  3. These cause vasodilation - blood vessels widen
  4. More blood flows to surface tissues
  5. Face: visible as blushing
  6. Stomach: internal, but same process
  7. Other areas affected:
  8. - Ears (turn red)
  9. - Neck (flushes)
  10. - Chest (can feel warm)
STEP 3
WHY IT HAPPENS (2 minutes)
  1. Evolutionary response to social situations
  2. Blushing signals embarrassment/shame
  3. May have evolved as social signal
  4. 'I recognize I made a mistake'
  5. Triggers empathy in others
  6. But why stomach? Possibly:
  7. - Stress response affects digestion
  8. - Preparation for 'fight or flight'
  9. - Side effect of overall vascular response
STEP 4
MIND-BODY CONNECTION (3 minutes)
  1. Shows emotions aren't just 'in your head'
  2. They create physical changes throughout body
  3. Stress affects:
  4. - Digestion (stomach lining)
  5. - Heart rate
  6. - Breathing
  7. - Muscle tension
  8. This is why:
  9. - Stress causes stomach issues
  10. - Anxiety affects appetite
  11. - Emotions influence physical health
  12. Your mind and body are deeply connected!
