Motion sickness is a conflict between the eye and ear: The inner ears detect movement, but the eyes — focused within a car or other vehicle — do not. These mixed signals coming into the brain can cause nausea, dizziness, vomiting, paleness, and cold sweats. When you go camping, you would make sure that you have plenty of food. Astronauts do the same thing when they go to space. They prepare food depending on their type.
Some food in space can be eaten in their natural forms like fruits and brownies, other food requires adding water like freeze-dried foods spaghetti or macaroni and cheese and dehydrated drinks. There is an oven on space to keep the food warm, however, there is no refrigerator. They eat 3 meals per day plus periodic snacks. Salt and pepper are available but only in a liquid form. The salt and pepper would simply float away.
Why can astronauts only eat certain types of food in space? Q and A, astronauts challenges in space Why do astronauts wear spacesuits?
The reason why astronauts wear spacesuits and inside the space station have a special shield that protects them from harmful radiation. Why do astronauts have to exercise daily in space? Why astronauts do not cry in space? Normally, our body compensates for the pull of gravity and works very hard to provide a normal circulation for the fluids in the body the blood, the lymph and the cerebrospinal fluids causing abody fluids disturbance.
In space, due to microgravity, fluid shifts away from the legs and up toward the head. For this same reason, astronauts do not cry in space the same way they do on earth. Their eyes make tears, but they stick as a liquid ball that hangs out in the eye and makes them feel worst. Why astronauts do not take shower in space? All of the water that the astronaut gets has to be flown up by rockets.
Astronauts do not take shower the way we do and instead, they take a sponge bath. Astronauts clean themselves with a towel, soap, and a little water and use a dry shampoo to clean their hair. To prevent the spread of germs , astronauts should keep themselves clean and their environment too. Why do astronauts lose weight in space?
