Why is there less oxygen at altitude?

Because atmospheric pressure decreases as you gain elevation, the air is less concentrated. Because the air is thinner, each breath brings in fewer air molecules. As a result, there is about 30% less oxygen in most Western ski resorts than at sea level.

What is altitude simulation?

Altitude simulation is controlling oxygen levels. ACT’s system duplicates the oxygen level of sea level. So your body responds and functions just as it does at low altitude.

Do you still acclimatize to altitude if you sleep in an oxygenated room?

Yes. When you sleep 6-9 hours in an ACT room, you still spend 15-18 hours at altitude. This is enough exposure to trigger acclimatization. But with this approach, you acclimate asymptomatically – without headaches or insomnia. The symptoms of mountain sickness do not help you to acclimatize. Even after acclimatization, sleep can still be disrupted at altitude. That is why it makes sense to oxygenate your bedroom.

Can adding oxygen to my house increase fire risk?

Not with an ACT system. Ordinary oxygenation can increase fire risk, but ACT’s system meets NFPA standards for safe oxygen levels, so there is no increased fire risk. ACT’s system has been tested by NFPA certified engineers and meets NFPA’s standard. ACT is the only company that meets this standard for fire-safe oxygen use. Read report here.

Are there any side effects from sleeping in an oxygenated room?

No. ACT’s oxygenation system only restores oxygen levels to sea level. There are no side effects, only better sleep, and prevention of altitude sickness.

“Providing oxygen during sleep is a side-effect-free way to treat altitude related insomnia.”Peter Hackett, M.D., Institute of Altitude Medicine
