      Has anyone here used an altitude tent to increase their performance? It's getting more popular for athletes to make their bedrooms into a high altitude chamber of sorts. They seal it up and use a special pump that controls the CO2 levels. source of picture

      I've always wondered about them! We always hear that athletes do best living at 8,000' and I've wondered if a hypoxic tent is equivalent. I tried to rent one before climbing with @Kevin in the Sierras, but too many 💰💰💰 were involved.

      I’m also curious as to how many hours per day you have to spend in it besides sleeping to actually trigger your body to start producing more red blood cells?

      I think that altitude acclimation kicks in after 3-5 days and you’ll need about 1-2 weeks to start seeing results while spending 24 hours per day at altitude.

      Sleeping hours is enough to acclimatize though I don't know how long it takes or if it can be sped up by spending more hours in it. When climbing it takes a day for every 1000' or so I've read. I guess it varies a bit depending on the person.

      Yeah it'd definitely help but then as long as you aren't sleeping at altitude I wouldn't be worried about it unless you wanted to make sure you weren't slowing up the other person. I never considered renting this equipment but it definitely makes sense for trips like you are talking about.
