1. A NEW WORLD Researched by: John Paul Alcazaren

2. Health Implications The presence of gravity helps sustain life on Earth. The lack of gravity in outer space is an obstacle to living in space. Living in space is not the same as living on Earth. Many things are different. Our bodies change in space.

3. Influence on blood circulation

4. The bones become weaker because of a loss of minerals (calcium, potassium and sodium). This bone degradation can reduce bone in the lower limbs by up to 10%. Influence on the bones

5. Influence on the muscles The musculoskeletal system continuously deteriorates. The muscles, in particular the leg muscles, which are underused, become flabby and lose tone and mass. The astronauts are then subject to muscular atrophy.

6. Influence on the body systems People living in space would be much more susceptible to illness and disease, as space weakens the body's immune system. The body also produces fewer red blood cells when in space, resulting in something called space anemia. Zero gravity affects the cardiovascular system by slowing down the heart.

7. How to keep ourselves healthy in space Exercise - People need to exercise vigorously to prevent muscle loss and bone deterioration. Monitor fluid intake - People living in space would need to constantly monitor their fluid intake to prevent fluid dehydration. They have to rest their bodies to have time to make new blood and water. If they don’t, they can feel very weak and might even faint.

8. How to keep ourselves healthy in space (continued) Keep clean and neat - In space, people need to keep clean and neat to stay healthy. Astronauts use toothpaste and toothbrushes just like yours. Astronauts take sponge baths daily, using two washcloths, one for washing and one for rinsing, and use rinseless shampoo to wash their hair. The air quality on the shuttle and the station is vital to the astronauts. Without oxygen, the crew would get fatigued, black out and die.

9. How to keep ourselves healthy in space (continued) Get enough sleep and rest - Sleeping can be a problem when you are weightless. Astronauts must strap themselves down when they sleep to avoid bumping into things. Station and shuttle crews have sleeping bags that can be attached to a seat or the wall. At one time, the astronauts can sleep anywhere in the station, as long as they attach their sleeping bags to something.

10. How to keep ourselves healthy in space (continued) Nutrition – Eat adequately and with proper nutrition will enhance people’s general well-being. Monitor vital signs - Keep track of your blood pressure, pulse rate, heart rate and respiration. Communication – Keep yourself open to communication with other people around you. Having a good relationship with others will inspire you and will not get you bored in space.
