It had been reported that, on Shenzhou 5, astronaut Yang Liwei suffered from a "minor heartache" after his launch. It is thought that this refers to space adaptation syndrome experienced by about one third of astronauts during the first few days of a spaceflight. The "People's Daily" said that the interior design of the spacecraft has been changed to hopefully lessen the likelihood of nausea and other symptoms.
