1. Drinking Water: Astronauts take water in liquid or gel-based form. Special food packaging and hydration systems are designed to make the experience more comfortable in zero gravity.
2. Using Straws: For liquid food or drinks, astronauts use pouches equipped with straws. Specialized packaging prevents spills due to surface tension.
3. Handling Sweat and Moisture: Breathable clothing helps absorb and regulate sweat. Astronauts wipe off sweat with antibacterial towels to maintain hygiene and prevent dehydration.
4. Managing Hygiene: Astronauts follow strict hygiene protocols, often using a wet cloth instead of a shower. Toothpaste and hand sanitizers without water are also employed.
5. Handling Other Body Fluids: Astronauts train for situations like vomiting or managing bodily waste in zero gravity. They use specialized equipment and waste disposal systems.
6. Medical Considerations: Astronauts undergo thorough medical training and monitoring to detect any health issues that may arise due to changes in body fluid distribution in space.
