Mother's Fears Are Passed to Children Through Smell, Study Suggests

Click title for full story
 

Story at-a-glance:

  • Hereditary trauma can be passed down from generation to generation, such that children may suffer from the same behavioral issues, fears, and phobias as their parents
  • In an animal study, newborn pups learned to fear the smell of peppermint their mothers had been conditioned to fear prior to pregnancy
  • Traumatic stress alters “microRNAs” in mice blood, brains, and sperm, leading to significant alterations in offspring that impact behavior
  • An imbalance in microRNAs in sperm, brought on by trauma, is one way in which emotional trauma is passed down through generations, a factor that is likely triggered when the body produces too much stress hormone
