How many hours do astronauts exercice?
atleast two hours a day The human body tends to lose muscle and bone mass rapidly in space. To fight this loss, at least two hours of strenuous exercise is built into every astronaut's daily schedule on the Space Station.
Why do astronauts have reduced skeleton?
There are 2 types of cells that populate living bone: osteoblasts (cells that build new bone) and osteoclasts (cells that destroy and recycle old bone). A feedback system based on stresses in the bone keeps the operation of these cells in balance. Where there is more stress the osteoblasts become more active and strengthen the bone, where there is less stress the osteoclasts become more active and weaken the bone. Normally gravity and movement provide these stresses needed to keep the bones healthy. However in the low gravity environment of space, the stresses are insufficient and imbalance results with the osteoclasts becoming more active and the bones become unhealthily weak.

Why do Astronauts have to be very fit before going into space?
Why have scientists developed exercises for astronauts living in outer space for long periods of time? Due to lack of gravitational field all the systms of the body but especially the musculoskeletal system is affected, in terms of bone resorption. To mninimize the effects of zero gravity exercises are developed.
Is it dangerous being a astronaut?
1: Radiation - Any planet/moon/or even space that is not protected by an atmosphere like Earth experiences radiation. That is a major reason why space travel is so dangerous. Radiation is everywhere in space. its like you can't escape it!2: they also have to worry about bone and muscle degeneration caused by spending all of that time in microgravity (exercise can also slow this problem but not prevent it)3: when the shuttle is fully loaded with the oxygen they need, it is extremely dangerous, so if one of the crews on the shuttle fart, they will interfere with the oxygen4: they suffer from boredom, cabin fever and muscle atrophy5: it is very difficult to digest food because there is no gravity acting on their body. Also, it is very bad for their bodies to be in an anti gravity for such a long period of time.6: Lack of food, lack of air and warmth.

Astronauts exercise when in space because bone atrophy under conditions of weightlessness or lack of?
exercise, leading to muscle and bone loss. Regular exercise helps maintain muscle strength and bone density, reducing the negative effects of prolonged space travel on the astronaut's body.
Why do you lose bone density in space?
In space, the lack of gravity-induced pressure on your bones leads to decreased bone density because your body does not need to support its weight in the same way as it does on Earth. As a result, astronauts in space experience bone loss due to reduced mechanical stress on their bones, which can lead to weakened bones and an increased risk of fractures.
How do astronauts keep healthy in space?
Astronauts keep healthy in space by exercising regularly to prevent muscle and bone loss, following a balanced diet to maintain their nutritional needs, and staying hydrated. They also undergo regular medical check-ups and participate in scientific research to study the effects of space on the human body.
How do astronauts live in space?
Astronauts can live in outerspace because in the space station they have water that is recycled, electricity provided by solar panels, and freeze dried food to last them the duration of their trip.
What are some health issues astronaunts encounter when they return home?
As soon as six hours after takeoff NASA has found bone loss and muscle atrophy from disuse in their orbiting astronauts. When they return home this effect is reversed and they regain both muscle and bone that they lost in space.
Why do astronauts need to do special exercises?
Astronauts need to do special exercises in space to prevent muscle and bone loss due to the lack of gravity. Without the effects of gravity on their bodies, muscles and bones can weaken and deteriorate over time. Special exercises help maintain their physical health during space missions and upon return to Earth.
How does microgravity effect the human body?
Muscle deterioration and bone loss are the main problems with prolonged living in low gravity. Astronauts do special exercies to avoid this when they spend time in space.
What do astronauts do all day in space?
Astronauts in space spend their days conducting experiments, maintaining the spacecraft, exercising to combat muscle and bone loss, communicating with mission control, and documenting their experiences through photography and videography. They also have scheduled periods for relaxation and personal time.
What problems do astronauts face in zero gravity?
Astronauts face several challenges in zero gravity, including muscle atrophy, bone density loss, fluid shifts in the body, and changes in spatial orientation. These issues can affect bodily functions and create discomfort for astronauts during space missions. Adaptation to the microgravity environment is crucial for the long-term health of astronauts during their time in space.
How Do Astronauts Cope With Weightlessness in space?
Astronauts cope with weightlessness in space by exercising regularly to maintain muscle and bone strength, using special equipment for daily tasks, and by taking medications to counteract the effects of fluid shift in their bodies. They also undergo training before the mission to adapt to the sensation of weightlessness.
Why do astronauts need to exercise while they are in the space station?
In a zero gee environment (weightlessness), the Human Body almost immediately begins losing muscle and bone mass. If they did not exercise, Astronauts returning from Space after a long stay on the Space Station would be unable to walk, and would have to be in a wheelchair for weeks before they could learn to walk again.
Can you do pull ups in space?
No, pull-ups cannot be performed in the traditional sense in space because there is no gravity to pull against. Astronauts on the International Space Station use specially designed resistive exercise equipment to maintain muscle and bone strength in microgravity environments.
