What's Happening?
A study published in Laryngoscope Investigative Otolaryngology reveals that 85% of astronauts aboard the International Space Station (ISS) have experienced nasal and sinus issues during their missions. The research, conducted by Houston Methodist, analyzed 754 medical events from 71 astronauts between 2000 and 2019. The study found that 75% of astronauts reported nasal congestion due to fluid shifts in microgravity. Spacewalks exacerbate these issues, causing pressure changes that lead to congestion, barotrauma, and Eustachian tube dysfunction, which can impair hearing and comfort. Researchers emphasize the need for pre-flight evaluations and treatments effective in microgravity to protect astronauts' breathing, sleep quality, and cognitive performance.

Why It's Important?
The findings highlight the significant impact of nasal and sinus issues on astronauts' health and mission performance. As human spaceflight and space tourism become more prevalent, understanding and addressing these health challenges is crucial. The study suggests that even the fittest individuals, like astronauts, face substantial sinonasal complaints in space, raising concerns about civilians with preexisting conditions traveling to space. Preventative measures and effective treatments are essential to ensure astronauts maintain peak performance, as breathing difficulties can affect cognitive function, reaction time, and overall mission success.
What's Next?
Researchers recommend pre-flight sinonasal evaluations and minor procedures to improve breathing for future astronauts. They also stress the importance of developing treatments that work well in space. As space tourism grows, addressing these health challenges will be vital to ensure safe and successful missions for both professional astronauts and civilian travelers.
