Changes

Overall, I think the AltoLab is a cost effective and useful way of training for high altitude conditions, and possibly for improvements at sea level. I suspect that the downsides of using other intermittent systems will be similar to AltoLab. From what I understand from other people who've slept in altitude tents, there are different, but equally significant downsides to that approach, including poor [[Zeo Sleep Monitor|sleep ]] quality.
