The likes of Manchester United stars Rio Ferdinand and Wayne Rooney are set to be ordered to sleep in tents at their plush homes.
The Daily Mail says England stars will soon begin their build-up to this summer's World Cup by sleeping in special altitude tents.
Fabio Capello's squad have been subjected to extensive tests over much of this season.
The results have shown that some of the players would benefit from starting to sleep in the tents at their homes in a bid to acclimatise to the high altitude conditions of South Africa.
Those who have proven to be more susceptible to the adverse effects of high altitude will have the tents delivered to their homes as soon as possible.
Sleeping at altitude can prove just as effective as training at altitude and the state-of-the-art equipment can replicate the exact heights of the World Cup venues.
