The three taikonauts aboard China's space station core module Tianhe have taken blood samples from each other to test their physical conditions. Taikonauts conduct regular blood tests to monitor their health while in space.

Meanwhile, they have been exercising, maintaining healthy diets and undergoing regular checkups to reduce the effects of living in a microgravity environment. Scientists have found that microgravity weakens muscles, which can accelerate the weakening of bones.
