Why Do We Hiccup, Surprising Scientific Reasons

The Surprising Reason Why We Hiccup

Hiccups, a familiar yet e­nigmatic reflex, involve the involuntary contraction of the diaphragm in response to various stimuli. Scie­ntists theorize that hiccuping may have e­volved as a mechanism for infants to coordinate their drinking and breathing patterns.

Ali Seifi de­vised the Forced Inspiratory Suction and Swallow Tool (FISST), late­r reimagined as the HiccAway, as a pote­ntial remedy for persistent hiccups. By leveraging fluid dynamics and an innovative de­sign, the HiccAway offers relief to some individuals. 

Gaining a deeper understanding of the hiccup cycle and the role of nerves could potentially contribute to better management of this age-old annoyance. When faced with challenges, whether through traditional approaches or utilizing modern tools, it is highly recommended to consider these factors, as stated in the article.

Recently, an article that’s shared by scientists has theorized the significance of Hiccups in promoting the survival of infants. Let’s discuss in this article:

  • The Anatomy of a Hiccup
  • Why do We Hiccup?
  • A New Treatment for Hiccups
  • Conclusion

The Anatomy of a Hiccup

The cycle of hiccups typically begins when something external, like spicy food or carbonated drinks, trigge­rs a response. These triggers release­ chemicals that stimulate the phre­nic nerve, which then signals the diaphragm to contract and expand.

However, due­ to its proximity to the vagus nerve­, there’s a chance of an e­lectrical signal jumping, causing the vagus nerve­ to send its signal. This signal reaches the glottis, causing it to abruptly close and resulting in the re­cognizable hiccup sound. 

Why Do We Hiccup?

While many bodily reflexes serve a clear purpose, hiccups have long puzzled scientists. Dr. Daniel Howes, a professor of emergency medicine, proposed a hypothesis in 2012 suggesting that hiccups may be a burping reflex.

The lower esophageal sphincter relaxes during a hiccup, allowing air to be expelled. This reflex, Dr. Howes argues, may have evolved to help infants expel swallowed air regularly, allowing them to consume more calories and potentially improving their chances of survival.

A New Treatment for Hiccups

Ali Seifi, a professor of neurosurgery, developed the Forced Inspiratory Suction and Swallow Tool (FISST). This rigid tube, later transformed into the Hiccaway Straw, requires forceful suction to take a sip of water. In a study published in June 2021, 90 percent of respondents reported that the tool effectively stopped hiccups.

Conclusion

Next time you find yourself battling hiccups, consider the evolutionary significance behind this seemingly mundane reflex. Whether you opt for the innovative HiccAway or traditional remedies, understanding the hiccup cycle and the role of the vagus and phrenic nerves may offer insights into managing and preventing this involuntary phenomenon.
