Tim Peake says readjusting to earth conditions is like world's worst hangover

British astronaut Tim Peake who landed on earth this Saturday morning from a six month journey on International Space Station (ISS). A Soyuz capsule carrying Major Peake and Russia's Yury Malenchenko and NASA's Tim Kopra touched down in Kazakhstan after spending 186 days in orbit.

Peake believes he is having world’s worst hangover as the human body takes time to adjust to earth conditions. Dizziness and a sense of vertigo is what surrounds Peake. Though the symptoms are expected to persist for anybody who has spent a sustained period of time in zero gravity.

During his 186 days stint aboard ISS Peake participated in more than 250 scientific experiments. Major Peake becomes the first British astronaut to be sent to ISS by European Space Agency.

For astronauts who spend longer periods of time in space take time in adjusting to the earthy conditions after their arrival. Being in space for longer duration may result in bone mass loss, muscle loss, weight loss and dizziness.
