How to stop hiccups?

To stop hiccups, Andrew Huberman recommends a specific breathing technique based on understanding the role of the phrenic nerve in causing hiccups. The method involves performing a series of three rapid intakes of breath through the nose without exhaling in between, followed by holding your breath for about 15-20 seconds, and then slowly exhaling. This approach hyperexcites and then relaxes the phrenic nerve, which can effectively alleviate the spasming that results in hiccups. This method has been described as the most efficient and scientifically supported way to stop hiccups 1.
