Altitude Dream
How it works

Smarter at altitude: how an altitude tent works

An altitude tent brings thin mountain air to your bedroom. You sleep in air with less oxygen, your body adapts, and during the day you live and train at sea level.

What is an altitude tent?

Mountain air without the mountain

An altitude generator filters part of the oxygen out of the air and blows oxygen-reduced air into the tent over your bed. Air pressure stays normal; only the oxygen percentage drops (normobaric hypoxia). This simulates altitudes from sea level up to 6,400 metres.

Live high, train low

Sleep at altitude, train at sea level

  1. 1You sleep at a set altitude at night.
  2. 2Your body produces more EPO and red blood cells.
  3. 3During the day you train at full intensity at sea level.

Pre-acclimatising at home lowers the risk of acute mountain sickness, shown in placebo-controlled research.

The science

What altitude training does to your body

Sleeping in lower oxygen (normobaric hypoxia) triggers measurable adaptations. A selection of what peer-reviewed research shows:

Perform stronger

  • Higher aerobic capacity (VO₂max) and endurance
  • More natural production of EPO and red blood cells
  • Higher lactate threshold, longer at high intensity

Adapt smarter

  • More mitochondria for efficient energy
  • Lower risk of altitude sickness through pre-acclimatisation at home
  • May support fat metabolism

Your SpO₂ sets your altitude

Every morning you measure your oxygen saturation with the supplied meter. That value steers your progression.

≥ 94%Raise altitude
90 to 93%Hold altitude (optimal adaptation zone)
≤ 89%Lower altitude

We supply an SpO₂ meter and guide you personally through the progression schedule.

For whom

For athletes and mountaineers

Athletes use the altitude tent for more endurance and faster recovery. Mountaineers pre-acclimatise at home to prevent altitude sickness and enjoy more of their expedition.

An altitude tent is not a medical device. If you have a medical condition (heart, lungs) or are pregnant, consult your doctor first. With symptoms at altitude, always descend and seek medical help.
