Memo for future astronauts 👽
Going into space and conquering neighboring planets is perhaps the dream of all children since Gagarin flew to the stars. But what happens to the body if you go into space right now? Telling 🚀🪐A sourcegiphy.com
🪐 Disturbed sleep
In space, there is no clear division into day and night, as on Earth. The circadian rhythms, which are responsible for alternating sleep and wakefulness, are in a panic: the body does not know when to sleep and when to get up. Of course, you can put on a sleep mask and turn on ASMR video, but the problem is in the schedule. Astronauts themselves have to set the hours of getting up and going to bed, as they see several sunrises and sunsets a day.
🪐 Clumsiness appears
The vestibular apparatus, which helps us walk straight on the ground and catch falling things, is guided by the fact that the body is almost always vertical. In the absence of gravity, the brain does not understand what to count as a starting point, and begins to “freeze”. For example, astronauts miss the right object, or the wrong muscle is responding.A sourcegiphy.com
🪐 Immunity adjusts
Living conditions on the space station are different from those on Earth. Due to gravity, sleep disturbances and cosmic radiation, the immune system changes and adapts to the environment. True, in the process, sores may appear that sat quietly in the body. Also, astronauts often suffer from rashes and allergies, which are also the immune system’s response to an irritant.
🪐 Blood circulation changes
The heart is located at the top of the body to better supply blood to the senses and brain. In fact, it turns out the opposite: more blood to the legs, less blood to the head. In space, blood enters all parts of the body in equal amounts, and therefore the legs lose weight and the head grows. Not to the point of bursting, of course, but still unpleasant.A sourcegiphy.com
🪐 Without a spacesuit
In short – you will die. Revealed – you will die in terrible agony. In outer space, a person is affected by vacuum, thermal radiation from the sun and radiation. The vacuum does not contain oxygen, and a person will die from a lack of oxygen within 1-2 minutes. Moreover, in a vacuum, liquids boil and evaporate. A person is at least 60% water, so the tissues of the skin and mucous membranes will stretch, leading to decompression sickness. But before that, you just burn in the sun and go blind, looking at a bright star. In general, do not fly, children, into space without a spacesuit 👨🚀
