On Earth, travel is a known trigger for gastrointestinal problems. Factors such as jet lag, dehydration, stress and irregular diet can easily disrupt the body’s normal rhythm. Podle Sarah Jane Bungerov\u00e9, vedouc\u00ed glob\u00e1ln\u00edho v\u00fdzkumu a v\u00fdvoje v Dulcolaxu, vytv\u00e1\u0159ej\u00ed tyto zemsk\u00e9 stresory \u201edokonalou bou\u0159i\u201c z\u00e1cpy, kter\u00e1 se jen zhor\u0161\u00ed, jakmile astronaut opust\u00ed zemskou atmosf\u00e9ru. <\/p>\n

The difficulty is not just about psychology or lifestyle; m\u00e1 hlubokou fyziologickou povahu. <\/p>\n

Jak mikrogravitace naru\u0161uje tr\u00e1ven\u00ed<\/h3>\n

In conditions of weightlessness, the human body is forced to function in conditions to which it was not evolutionarily adapted. The digestion process relies on two main mechanisms:<\/p>\n

    \n
  1. Peristalsis:<\/strong> wave-like muscle contractions of the digestive tract that move food through the system. <\/li>\n
  2. Gravity:<\/strong> a physical force that helps move waste throughout the lower gastrointestinal tract. <\/li>\n<\/ol>\n

    Ve vesm\u00edru mus\u00ed peristaltika d\u011blat v\u0161echnu t\u011b\u017ekou pr\u00e1ci sama. Without gravity to help move matter, the body’s natural processes become less efficient.

    The carrying capacity of spaceships is a limited and precious resource. Each item sent into orbit must justify its weight and volume. This need leads to the formation of an extremely selective list of medications. <\/p>\n
