Hiccups
Thank your diaphragm, the muscle beneath the lungs that helps you breathe, for the loud “hic!” sound that appears at the most inopportune moments. When the diaphragm contracts involuntarily, the top of your windpipe closes immediately, causing the common hiccup noise. Eating too quickly, drinking too much alcohol, or taking certain medications have been associated with hiccups, though the exact cause is still unclear. Unlike other uncontrollable reflexes such as sneezing or coughing, there is no clear, useful purpose for hiccups. Short bouts are harmless, but persistent hiccups that last for more than 48 hours should be evaluated. This could be a sign of an underlying medical condition.(Related: How to Get Rid of Hiccups, Once and for All)
