【文章內(nèi)容簡介】 zero gravity environment causes more liquid to shift to the head. Faces get swollen, legs lose volume and appear to be smaller. Many astronauts have plained of eye and back problems after ing back down to Earth and its gravity.And now scientists say they have discovered some new risks with longterm space flight. A study published recently in JAMA Network Open , a medical journal, examined 11 healthy astronauts who had been on the International Space Station for six months. Eight of them had unusual characteristics observed in their blood. For instance, six of the astronauts had reverse （反向的）blood flow from their heads.The lead author of the study says he doesn39。t know if that39。s actually harmful. The blood is still leaving the head from other pathways, so flowing backwards through a jugular vein.（頸靜脈）may not be dangerous. But he says it does show a change in how blood moves through the body while in space.Another issue the study found was blood clots （凝塊）. One astronaut had one. Another showed signs of a partial blood clot. That is potentially harmful as the clots can block the flow of blood to the lungs. The astronaut who had one was treated for the rest of the spaceflight and made it home safely.What does all this mean? Well, one researcher says these issues have probably been occurring since humans first went into space and that they would likely resolve themselves when astronauts came back down to Earth. Knowing about them now gives doctors something else to monitor when people leave our atmosphere.32. What causes the physical problems for astronauts?A. Sleeping for a long time. B.

Here are some basic steps that you39。ll want to follow.Share positive things, but not excessive （過度的）. Everyone has problems, but no one wants to read a bunch of negative soulsearching. Don5t plain, or endlessly describe your health problems, relationship dramas, kid problems, etc. 36 Take pride in who you are and what you are all about. It isn39。t helpful to criticize yourself.
