Challenges of living in zero gravity
Living in zero gravity is a unique experience that astronauts encounter in space. The human body has evolved to function within the environment of Earth’s gravity. Therefore, prolonged stays in zero gravity can have detrimental effects on an astronaut’s physical and mental health. Here are some of the challenges of living in zero gravity:
- Loss of bone density: Without gravity, bones do not experience the same stress and strain that they do on Earth. This results in the loss of bone density and make them brittle, increasing the risk of fractures. According to NASA, astronauts lose 1-2% of their bone mass per month in space.
- Loss of muscle mass: Muscle atrophy is a significant problem in space as the muscles are not used as they are on Earth. The loss of muscle tissue can affect an astronaut’s ability to carry out their tasks assigned, such as spacewalks. Astronauts have to carry out two hours of exercise daily to maintain their muscle mass.
- Fluid shift: Without gravity, fluids in the body move towards the upper body, creating congestion and headaches. The shift also reduces the amount of fluid in the legs, causing them to become thinner. This can make it challenging to stand on Earth too soon after landing.
Adapting to zero gravity
Adapting to life in space requires both physical and mental adjustments. Astronauts in space develop skills to help them adapt to the environment with time. These include:
- Learning to move: Movement in space takes some getting used to; it’s different from movement on Earth. Astronauts have to learn to push themselves off walls and move about without the use of their feet. They also have to learn different body orientation in space.
- Learning to eat in space: Food in space comes in freeze-dried packets, and astronauts have to learn how to rehydrate, and eat them. It also requires special utensils to hold the food and keep it from floating away.
- Learning to cope with isolation: Astronauts have to spend extended periods of time away from family, friends, and the familiar world. They develop coping mechanisms to deal with loneliness and anxiety and stay in touch with their loved ones on Earth through email and phone calls.
The importance of zero-gravity research
Despite the challenges of zero gravity, it presents a valuable opportunity to advance scientific research. Microgravity has been instrumental in medical research, such as the study of bone density loss, which is common in aging individuals and those with osteoporosis. It has also helped further our understanding of fluid dynamics and combustion, which has practical applications for multiple industries on earth. By overcoming the challenges of zero-gravity living, we can continue to explore and learn more about our universe.
| Challenge of Zero Gravity | Effect on astronaut’s Health |
|---|---|
| Loss of bone density | Increases risk of fractures and makes bones brittle |
