Space travel is an unprecedented adventure that requires special preparation and adaptation.

Although most people will not become professional astronauts immediately, understanding how to cope with the space environment is crucial for those who have the opportunity to participate in space tourism. Here are some key tips for preparation and adaptation.

Adapting to the Weightless Environment

In the first few days after entering space, you may experience what is called "space adaptation syndrome." This syndrome is similar to motion sickness or seasickness on Earth, but the symptoms can be more pronounced due to the weightless environment.

You may feel dizzy, nauseous, vomit, and even experience headaches. These symptoms are caused by the upward movement of fluid in the body, leading to facial swelling and increased head pressure.

Typically, the body gradually adapts to the weightless state after about four days. If the symptoms are severe, anti-emetic medicines can be taken, and maintaining a positive mood can also help alleviate discomfort.

Sleeping in Space

On Earth, we lie on a bed to sleep, but in space, due to the weightless environment, a bed is unnecessary. Astronauts usually secure themselves in sleeping bags attached to the wall of the spacecraft or space station.

Although this prevents the body from floating in the weightless environment, you may often feel the illusion of "falling" and be awakened. This is a common phenomenon in a weightless environment. Don't panic, as it will improve as you gradually adapt.

Solving the "Convenience" Problem

Using the restroom in space is quite challenging. During launch and return, you need to sit in a fixed seat for long periods, and the heavy spacesuit is not conducive to frequent removal.

To address this problem, astronauts use special diapers. These diapers were originally designed for astronauts and can absorb a significant amount of liquid. Although it may make you feel a bit embarrassed, it is the most effective method currently available.

Dietary Adjustments

The diet in space is also different from that on Earth. The weightless environment can cause your sense of smell and taste to weaken, making food seem bland and tasteless.

Therefore, astronauts' diets usually include strong-tasting seasonings such as chili sauce to stimulate the taste buds and enhance appetite. In addition to regular food, a special logistics team delivers food suitable for the space environment.

Sneezing Tips

Sneezing might be a small action on Earth, but it requires special attention in space. Due to the weightless environment, bacteria expelled during sneezing will float in the air, increasing the risk of infectious diseases.

To avoid this, cover your mouth and nose with a towel when you sneeze. This act not only prevents the spread of bacteria but also protects the health of other astronauts.

The Correct Way to Burp

In a weightless environment, the contents of the stomach do not sink to the bottom as they do on Earth but are evenly distributed. Therefore, if you don't pay attention when burping, it is easy to cause vomiting.

To prevent this, you can push against a wall with your hand before burping, using the reaction force to stabilize the contents of your stomach. This way, only the gas will be expelled, and you can burp normally.

Precautions for Showering

Taking a shower in space is also challenging. Water will float around in a weightless environment. To address this, the U.S. space stations have designed special shower devices.

You need to enter a closed cylinder with a pressurized water spray device inside to ensure that the water does not float around. To prevent water from entering your mouth and nose, you also need to wear a breathing mask, allowing you to breathe normally through a tube connected to the outside air.

Keeping Fit

In space, the lack of gravity can lead to bone and muscle loss, so at least two hours of exercise are required daily. Common exercises include cycling, but bicycles in space do not have handlebars and seats, allowing you to engage in other activities while riding, such as reading or operating a music player. It not only keeps you healthy but also enriches your life in space.

By understanding and practicing these essential tips, you can ensure a safer and more enjoyable experience in space. From adapting to a weightless environment to maintaining communication with Earth, each step brings you closer to becoming a well-prepared space traveler. Embrace the journey, and let your dreams of space exploration become a reality.
