Astronauts on the ISS use a device called the Hygiene Maintenance System (HMS) to bathe. The HMS consists of a showerhead and a wastewater recovery system. The wastewater is collected and treated on board the ISS before being released back into the environment.
3. How do astronauts brush their teeth in space?
Astronauts use a toothbrush and toothpaste in space, just like they do on Earth. They spit out the toothpaste into a waste bag, as there is no sink to dispose of it in. They also use wet wipes to clean their faces and hands.
4. How do astronauts manage their hair and nails in space?
Astronauts are not allowed to cut their hair or nails in space, as it could potentially cause a hygiene problem. They also cannot use hair products or nail polish, as they could cause fumes that could affect the air quality on the ISS.
5. How do astronauts deal with body odor in space?
Astronauts use antiperspirant and deodorant to control body odor in space. They also wear spacesuits, which help to keep them clean and fresh. The air on the ISS is also constantly circulated and filtered, which helps to maintain a clean and odor-free environment.
