Altitude Sleeping Tent
Simulate High Altitude From Your Own Bedroom
Altitude sleeping tents allow athletes and mountaineers to simulate high-altitude environments while they sleep, helping the body adapt to lower oxygen levels over time.
By reducing the oxygen concentration inside the tent, athletes can follow the well-known “sleep high, train low” protocol, which is widely used in endurance sport and expedition preparation.
Instead of travelling to altitude, an altitude sleeping system allows you to integrate hypoxic exposure directly into your training routine.
What Is an Altitude Sleeping Tent?
An altitude sleeping tent is a sealed enclosure that fits over a bed and connects to a hypoxic generator that lowers the oxygen concentration inside the tent.
This creates a simulated altitude environment typically ranging from:
-
2,000m (6,500 ft) – moderate altitude exposure
-
2,500m (8,200 ft) – common endurance training level
-
3,000m+ (9,800 ft+) – advanced altitude adaptation
Athletes sleep inside the tent while the generator delivers hypoxic air, gradually allowing the body to adapt to reduced oxygen availability.
Over time this exposure can trigger physiological responses associated with altitude acclimatisation.
Benefits of Sleeping at Altitude
Altitude sleeping systems are widely used by endurance athletes because many key adaptations occur during prolonged exposure.
Improved oxygen transport
Altitude exposure stimulates the body to adapt to lower oxygen availability.
Increased endurance efficiency
Many athletes report improved aerobic performance following altitude training blocks.
Expedition preparation
Mountaineers preparing for high-altitude expeditions often use altitude sleeping tents to begin acclimatisation before travel.
Convenient altitude exposure
Athletes can train at normal intensity during the day while gaining altitude exposure overnight.
Sleep High, Train Low
One of the most widely used altitude strategies is the sleep high, train low method.
This approach involves:
-
Sleeping at simulated altitude to stimulate physiological adaptation
-
Training at normal oxygen levels to maintain training intensity.
Altitude sleeping tents allow athletes to apply this strategy without relocating to high altitude environments.
This approach is commonly used by:
-
endurance cyclists
-
triathletes
-
marathon runners
-
mountaineers
-
professional sports teams.
How Altitude Sleeping Tents Work
Altitude sleeping systems use a hypoxic generator that reduces oxygen concentration in the air delivered into the tent.
Normal air contains approximately 21% oxygen.
Inside an altitude sleeping environment this may be reduced to simulate high elevation conditions.
The generator pulls air through a filtration system that separates oxygen and nitrogen, delivering air with a lower oxygen concentration into the tent.
The result is a stable hypoxic environment that can simulate elevations of several thousand metres while you sleep.

Frequently Asked Questions
Do altitude sleeping tents really work?
When used consistently, altitude exposure can trigger physiological adaptations associated with endurance performance and altitude acclimatisation.
How many hours should you sleep in an altitude tent?
Many athletes aim for 6–10 hours per night during altitude training blocks lasting several weeks.
What altitude should I start with?
Most athletes begin with simulated altitudes around 2,000–2,500m, gradually increasing exposure as the body adapts.
Are altitude sleeping tents safe?
Altitude systems are widely used by athletes and sports science laboratories when used correctly and with appropriate monitoring.
