What should we pay attention to in space tourism? What should we pay attention to in space tourism?

1, how to adapt: survive the "seasickness period" of 4 days. There will be "motion sickness and seasickness" on the earth, and space will be the same, and it will "faint the spaceship". In the first few days of your flight, there may be "space adaptation syndrome": vomiting, dizziness, headache and weightlessness will also cause your blood to accumulate in your head and your face will become swollen. But don't worry too much. Keep a good mood. If it is serious, take antiemetic drugs. Generally, after 4 days, your body is used to weightlessness, and your symptoms will naturally improve.

2, how to sleep: "hanging" on the wall. On earth, we all sleep in beds, but there are no beds in spaceships and space stations, only sleeping bags are covered on the walls. If you are sleepy, just get into your sleeping bag, zip yourself up and fix yourself, and you can sleep peacefully. However, it should be noted that when you sleep, you may often feel "falling down" and then wake up. Don't panic, this is affected by weightlessness, and many astronauts have this experience.

3, how convenient: diapers are "artifacts." Speaking of diapers, you must think they are for babies, but in fact they were originally designed for astronauts. There are two difficulties in "convenience" in space: one is to sit in a fixed seat when launching and returning, and the other is that the bulky spacesuit cannot be put on and off easily. Astronauts have used a variety of methods, such as double rubber pants and improved condoms, but the results are not good. Until the 1980s, a China engineer named Tang Xinyuan of NASA invented a diaper that can absorb 1.400 ml of water by using polymer absorber, which solved the problem of astronauts. So even if you feel embarrassed, put on a diaper.

4, how to eat: need heavy taste to wake up the taste buds. Tell you a fact: the space environment will make everyone a heavy taste lover. Why? Because of weightlessness, mucus accumulation in nasal cavity and insufficient saliva secretion in tongue, it will weaken your sense of smell and taste and make everything tasteless. Therefore, in addition to the food we eat every day, the logistics department will also deliver heavy spices such as Chili sauce to help you open your appetite.

5. How to sneeze: Bring a towel. If you have read the Hitchhiker's Guide to the Galaxy, you must be impressed by this sentence: "Towels are the most useful thing for interstellar rovers." As far as sneezing is concerned, this sentence is very correct. When you sneeze on the earth, bacteria will fall to the ground and be destroyed by sunlight. However, in space, the ejected pathogenic bacteria will always float in the air, multiply rapidly, and easily get infected with diseases. In the 106 space flight recorded by NASA, there were 29 cases of infectious diseases. So don't forget to cover your nose and mouth with a towel before sneezing.

6. How to burp: Push the wall with your hand. This action may confuse you, but if you don't do it, hiccups can easily turn into vomiting. Because of weightlessness, the substances in the stomach no longer stay at the bottom of the stomach, but are evenly distributed in the stomach. So you need to push the wall before burping, and use the reaction force exerted by the wall instead of gravity to "fix" the substances in your stomach, so that you can only expel the gas from your stomach and burp normally.

7. How to take a bath: Take a bath with a respirator. Bathing in weightlessness is a hassle, and water will float around. But don't worry, scientists have found a solution. The Sky Laboratory in the United States and the salute space station in Russia have been equipped with special shower devices-the upper part is a pressurized nozzle and the lower part is a closed cylinder made of waterproof material, which can be washed by closing the joint. In order to prevent water from entering through the nose and mouth, don't forget to bring your nose and mouth respirator when you enter the gas cylinder. The tube of the respirator will communicate with the outside air so that you can breathe freely.

8. Special attention: you must exercise for two hours every day. It doesn't matter if you don't exercise on the earth, but in space, it is a bit dangerous-weightlessness will lead to bone and muscle loss, osteoporosis and other diseases, and you must rely on exercise to maintain your health. Therefore, you need to exercise for two hours every day. A common sport is riding a bicycle, but bicycles in space have no handlebars and seats, so your hands can be completely "liberated", you can turn pages and operate a music player.
