Too Clean, Space Station Makes Astronauts Sick
- Astronauts aboard the International Space Station (ISS) frequently experience skin rashes, unusual allergies, and various infections, including fungal infections, cold sores, and shingles.
- Researchers suggest a possible cause: the orbiting laboratory's excessive hygiene may lead to a lack of necessary microbes.
- While bacteria commonly found in or on the human body travel to space with the astronauts, many free-living microbes present on Earth are absent in the ISS environment.

Astronauts aboard the International Space Station (ISS) frequently experience skin rashes, unusual allergies, and various infections, including fungal infections, cold sores, and shingles.
Researchers suggest a possible cause: the orbiting laboratory’s excessive hygiene may lead to a lack of necessary microbes.
While bacteria commonly found in or on the human body travel to space with the astronauts, many free-living microbes present on Earth are absent in the ISS environment.
Scientists hypothesize that this microbial imbalance could contribute to chronic inflammatory diseases. They believe that cultivating a diverse range of microbes within the ISS, and potentially future space stations, could improve astronaut health.
Over 280 astronauts have visited the ISS in its 25-year history. To better understand the conditions within the station,researchers from the University of California San Diego (UCSD) and NASA collaborated to map the microbes present.
Their findings indicate that the ISS is more sterile than typical terrestrial living environments. The bacteria identified are often associated with immune-related symptoms.
A study published in February in the journal *Cell* detailed how astronauts and microbiologists, including Kathleen Rubins, collected over 700 surface samples and 60 control device samples within the ISS to map the microbial environment.
The majority of bacteria found were those associated with humans, with a notable absence of bacteria commonly found in soil and water on Earth.
One researcher, Knight, stated, Your immune system requires exposure to various useful microbes from places such as soil, healthy animals, and healthy plants.
the quote was reported by The New York Post.
Knight added, Understanding whether there is a way to package the healthy microbial or supply it to ecosystems in space that can be maintained by Astronaut is a very interesting research topic today.
Rubins also suggested that living conditions on the ISS might contribute to skin problems.
We do not have a shower on ISS and can only use a little water to wash. We wear our clothes for two weeks in a row because we don’t have a way to wash clothes in space.Kathleen Rubins, Astronaut and Microbiologist
Rubins emphasized the importance of understanding how to promote a diversity of healthy microbes as humans explore beyond earth.
We may need to bring more outside air (on earth) into this house (ISS).However, we must do it safely so that there is no fungal growth or pathogenic things.Kathleen Rubins,Astronaut and Microbiologist
ISS Hygiene: A Balancing Act for Astronaut Health
Learn about the challenges of maintaining astronaut health in space and the role of the International Space Station’s (ISS) environment.
Why Do Astronauts Experience Health issues on the ISS?
Astronauts aboard the International Space Station (ISS) sometimes face health challenges such as skin rashes, unusual allergies, and various infections, including fungal infections, cold sores, and shingles. A crucial factor contributing to these issues might be the sterile, and highly controlled environment aboard the orbiting laboratory.
What is the primary concern regarding hygiene on the ISS?
The excessive hygiene practices on the ISS, while intended to protect astronauts, may lead to a lack of necessary microbes. This microbial imbalance could be a significant factor in the health issues astronauts experience.
Are there any other factors which contribute to this situation?
Living conditions aboard the ISS contribute to skin problems, for example, there are no showers, and astronauts can only use a little water to wash.they wear their clothes for two weeks in a row as there is no way to wash clothes in space.
What is the Role of Microbes in Astronaut Health?
The absence of many free-living microbes that are present on Earth is a significant consideration. the human body is accustomed to a diverse microbial environment, and without it, the immune system may not function optimally.
Why is a diverse microbial environment important for health?
According to one researcher, “Your immune system requires exposure to various useful microbes from places such as soil, healthy animals, and healthy plants.”
What types of bacteria are found on the ISS?
Most of the bacteria discovered on the ISS are those commonly associated with humans, with a notable absence of bacteria frequently found in soil and water on Earth.
How are Researchers Studying the ISS Environment?
Understanding the conditions inside the ISS is essential for addressing these challenges. Researchers have been actively working to map and analyze the microbial environment, as well as understand its impact on astronaut health.
What methods are used to study the ISS environment?
Researchers have collected hundreds of surface samples to map the microbial environment. Scientists from the University of California San Diego (UCSD) and NASA collaborated to study the microbes present to achieve this. Analyzing these samples helps identify the types and distribution of microbes within the station.
What are the future research goals?
The goal is to understand how to bring more diverse microbial into the ISS. However, doing so must be done safely so that there is no fungal growth or pathogenic things.
What are the Key Differences Between Earth and ISS Microbial Environments?
A study published in the journal *Cell* has identified the key differences between the environments.
| Environment | Microbial Characteristics | Impact on Astronauts |
|---|---|---|
| Earth | Diverse, including soil and water microbes | Supports immune function and overall health |
| ISS | less Diverse, primarily human-associated microbes | Potential for increased susceptibility to infections, skin problems, and allergies |
What are the Long-Term Benefits of this Research?
the insights gained from studying the ISS environment will be extremely valuable for future space exploration efforts. This research is important for establishing safe and healthy living conditions for astronauts as humans venture beyond Earth.
