Astronauts require less sleep than normal; Theoretically because the astronauts always have to be alert in a dangerous setting like space.
their suits are very heavy.
Most astronauts have to go to the hospital anyways for a check up before they leave for space. Some astronauts get hurt or injured n space and may need to get tothe hospital when they return. When astronauts get back they have an examination too. Astronauts are highly trained, but they are still human and can get sick or injured like anyone else.
You need a passport to cross from America to Canada. While inside Canada, you don't need your passport, except for ID purposes.
Astronauts wear special costumes, commonly referred to as "space suits" that protect them from the rays of the sun and gasses depending on which planet they are on. Space suits are airtight and also keep them warm while in the freezing vacuums of space, and cool inthe scorching sun. They wear a tinted glass for their face, not to be blinded by the glare.
Yes, astronauts wear specialized clothing while living and working inside the space station. They wear comfortable clothes for daily activities and special space suits for spacewalks or emergencies. These suits provide protection from extreme temperatures, radiation, and microgravity conditions.
They need to take it with them. There is no oxygen in space
Space suits: to protect astronauts from extreme temperatures, micrometeoroids, and provide oxygen. Extravehicular Mobility Units (EMUs): for spacewalks to enable astronauts to move and work outside the spacecraft. Tether systems: to keep astronauts connected to the spacecraft while working in space.
food, water, shelter
I am not sure, ask NASA
Spacecraft need an internal oxygen supply to provide a breathable atmosphere for astronauts during space travel. Since there is no oxygen in space, spacecraft must carry their own supply to support human life. This ensures that astronauts have the necessary oxygen to breathe and carry out their activities while in space.
You need space food to give nutrition to astronauts. They need energy to perform tasks thus need food.

Astronauts need to know chemistry to understand how different materials and substances behave in the unique environment of space, such as changes in temperature, pressure, and radiation exposure. This knowledge is essential for the maintenance and operation of spacecraft systems, as well as for performing experiments and research in space. Understanding chemistry also helps astronauts stay safe and healthy while living and working in space for long durations.

No, you cannot add pages to your passport once it is issued. If you run out of space for stamps and visas, you will need to apply for a new passport.
They need to wear something that is thick and something that is a space suit... they for sure need to put their pee on their face.
