The Effects of Excessive Crying

Is Excessive Crying Harmful?

Science tells us that when babies cry lonely and unattended, they feel panic and feet. When trying to empathise if excessive crying is harmful for babies, recall virtually the fact that their bodies and brains are flooded with adrenaline and cortisol stress hormones and when developing brain tissue is exposed to these hormones for prolonged periods, these fretfulness won't form connections to other nerves and will degenerate.

Is it therefore possible that infants who endure many nights or weeks of crying-it-out alone are actually suffering harmful neurological effects that may take permanent implications on the development of sections of their encephalon?

Here is how science answers the question of whether excessive crying is harmful:

Chemical and Hormonal Imbalances in the Brain

  • Research has shown that infants who are routinely separated from parents in a stressful way accept abnormally high levels of the stress hormone cortisol, as well equally lower growth hormone levels. These imbalances inhibit the development of nerve tissue in the brain, suppress growth, and depress the allowed system. (v, 9, 11, 16)
  • Researchers at Yale University and Harvard Medical School found that intense stress early in life can alter the brain's neurotransmitter systems and crusade structural and functional changes in regions of the encephalon like to those seen in adults with low. (17)
  • Ane report showed infants who experienced excessive crying episodes were x times more probable to take ADHD as a child, along with poor school performance and antisocial behavior. The researchers concluded these findings may be due to the lack of responsive attitude of the parents toward their babies. (14)
  • Dr. Bruce Perry's research at Baylor University may explain this finding. He constitute when chronic stress over-stimulates an infant's brain stem (the part of the brain that controls adrenaline release), and the portions of the brain that thrive on physical and emotional input are neglected (such as when a babe is repeatedly left to cry alone), the child volition grow upwardly with an over-active adrenaline system. Such a child may display increased aggression, impulsivity, and violence afterward in life because the brain stalk floods the body with adrenaline and other stress hormones at inappropriate and frequent times. (6)
  • Dr. Allan Schore of the UCLA School of Medicine has demonstrated that the stress hormone cortisol (which floods the brain during intense crying and other stressful events) actually destroys nerve connections in disquisitional portions of an infant's developing brain. In addition, when the portions of the brain responsible for attachment and emotional command are not stimulated during infancy (as may occur when a baby is repeatedly neglected) these sections of the brain will not develop. The result – a violent, impulsive, emotionally unattached child. He concludes that the sensitivity and responsiveness of a parent stimulates and shapes the nerve connections in key sections of the brain responsible for zipper and emotional well-being. (7, 8)

Decreased Intellectual, Emotional, and Social Development

  • Baby developmental specialist, Dr. Michael Lewis, presented research findings at an American Academy of Pediatrics meeting, concluding that, "The single most important influence of a child's intellectual evolution is the responsiveness of the mother to the cues of her baby."
  • Researchers take establish babies whose cries are normally ignored will not develop healthy intellectual and social skills. (19)
  • Dr. Rao and colleagues at the National Institutes of Wellness showed that infants with prolonged crying (but non due to colic) in the first 3 months of life had an average IQ 9 points lower at 5 years of age. They also showed poor fine motor development. (ii)
  • Researchers at Pennsylvania State and Arizona State Universities found that infants with excessive crying during the early months showed more than difficulty controlling their emotions and became even fussier when parents tried to console them at 10 months. (15)
  • Other research has shown that these babies have a more annoying quality to their weep, are more clingy during the day, and take longer to get independent as children. (1)

Harmful Physiologic Changes

  • Fauna and homo research has shown when separated from parents, infants and children bear witness unstable temperatures, center arrhythmias, and decreased REM sleep (the stage of sleep that promotes brain evolution). (x, 12, 13)
  • Dr. Brazy at Duke University and Ludington-Hoe and colleagues at Case Western Academy showed in 2 separate studies how prolonged crying in infants causes increased claret pressure in the brain, elevates stress hormones, obstructs claret from draining out of the brain, and decreases oxygenation to the brain. They ended that caregivers should answer cries swiftly, consistently, and comprehensively. (three, 4)
