“I hadn’t realized I’d learned to talk with a weightless tongue.”

-Commander Chris Hadfield spoke earlier today from Houston during his first press conference since returning to Earth.

Hadfield said that symptoms of adapting to Earth after four months of weightlessness on the International Space Station include dizziness, a sore body and neck and difficulty walking and exercising. He has to sit down while taking a shower so he doesn’t faint, and with no callouses on his hands and feet, walks around like “walking on hot coals.”

During the press conference, he wore a G-suit underneath his clothing to coax the blood back up to his head. Learn more about his adjustment from space to Earth here.
