Since July 16, Uznański-Wiśniewski has been undergoing post-mission rehabilitation at the European Astronaut Centre at the German Aerospace Center in Cologne, Germany, following his return from the International Space Station.

During his time in space, the Polish astronaut conducted 13 experiments as part of Poland’s IGNIS mission.

According to Alessandro Alcibiade, the IGNIS flight surgeon who oversaw Uznański-Wiśniewski’s health, blood tests of returning astronauts often show patterns similar to those in people who spend extended periods in polar stations or submarines.

Astronauts often experience facial redness caused by bodily fluids shifting upward in microgravity, along with swelling, dizziness, and disorientation, which usually ease after a few days of rehabilitation.

Supplementation is also needed to address deficiencies in certain vitamins and nutrients after spaceflight. Their conditions are additionally monitored for potential chances in bone density and DNA caused by prolonged exposre to ionizing radiation in space.
