How do astronauts test their physical condition during flight?

Astronauts are one in a million and have excellent physical fitness. However, due to flying in space for 1 19 hours, astronauts may get seasick, accompanied by symptoms such as vomiting and dizziness. To this end, before the launch of the spacecraft, the relevant medical personnel have prepared corresponding medicines on the spacecraft in case of emergency.

The reaction tray of air regenerator is an important emergency product. Once the hatch is not opened when returning, it will become the source of life for astronauts in the case of insufficient air: generating oxygen and absorbing carbon dioxide. Don't underestimate this metal bucket, which is less than 5 kilograms. It can keep the living air needed by two astronauts for nearly a day. In order to prevent accidents, China has organized many ambulance medical teams all over the world. They prepared thousands of milliliters of blood for the two astronauts in advance, which can be stored for 2 1 day.

In order to monitor the astronauts' physical condition, medical staff also prepared a special test vest for them. This kind of medical monitoring equipment can measure many physiological indexes of astronauts and send back relevant data through the ground station. Once the astronaut's body is found to be abnormal, the medical staff on the ground will take corresponding measures to inform the astronaut for treatment.

In order to prevent the spacecraft from landing in the non-designated landing zone, lifeboats, anti-immersion and cold-proof clothes, food, drinking water, tools, signal flares and other items needed by astronauts during their survival are also prepared in the cabin; For safety, we also prepared pistols, tree cutters and outdoor survival supplies.
