DO IT IN YOUR SLEEP

A hy­poxic tent means you can sleep at alti­tude with­out hav­ing to leave the house

First de­vel­oped by Hy­pox­ico in the 1990s, alti­tude tents can be a far eas­ier and cheaper al­ter­na­tive to spend­ing long pe­ri­ods of time liv­ing or stay­ing at high alti­tude for ac­cli­ma­ti­sa­tion. Un­like ‘real’ alti­tude, an alti­tude tent does not re­duce the baro­met­ric pres­sure of the air within. In­stead hy­poxic (oxy­gen-de­pleted) air from an alti­tude gen­er­a­tor is pumped con­tin­u­ously into the tent, dis­plac­ing the reg­u­lar air in­side along with any ex­haled car­bon diox­ide.

The hy­poxic air has about 12% oxy­gen con­tent com­pared to the 21% that sea level air con­tains. Us­ing this sys­tem, al­ti­tudes of up to 5,000m can be sim­u­lated in the com­fort of your own bed­room, al­low­ing ath­letes to sleep or rest in a hy­poxic at­mos­phere but train in their usual oxy­gen-rich en­vi­ron­ment. Pro­longed and reg­u­lar use has been shown to have sig­nif­i­cant ben­e­fits to ath­letic per­for­mance, so much so that WADA (World Anti-dop­ing Agency) con­sid­ered whether or not it should ban the use of alti­tude tents re­cently, although it was deemed too dif­fi­cult to en­force.
