ALTIMATE™ HIGH ALTITUDE
SLEEP MASK

THE ALTIMATE™ SLEEP MASK IS A DRUG-FREE INNOVATION CRAFTED BY SCIENCE AND PERFECTED BY THE HIGH ALTITUDE ADVENTURE COMMUNITY.

A lightweight, portable, and easy to use expedition essential, the Altimate™ Sleep Mask gives adventurers a natural edge, regulating breathing and minimizing periodic breathing during sleep at altitude.

WHAT IS ALTITUDE-INDUCED PERIODIC BREATHING?

Periodic breathing involves alternating between phases of hyperventilation followed by phases of intermittent, shallow breathing.

The shallow phases of breathing can include periods where breathing pauses entirely and you wake up gasping for air or signal your brain to increase ventilation and repeat the cycle with hyperventilation to improve oxygenation.

All of this atypical breathing can lead to disruptions in sleep, which in turn increases fatigue and may diminish enjoyment of your activity over time.

WHY DOES PERIODIC BREATHING HAPPEN AT HIGH ALTITUDES?

4. Ainslie P. N., Lucas S. J., Burgess K. R. (2013). Breathing and sleep at high altitude. Respir. Physiol. Neurobiol. 188 233-256.

At high altitude, however, your body senses lower oxygen (O2) levels in the blood and causes you to hyperventilate in an attempt to increase oxygen saturation levels. Though hyperventilation is an important aspect of acclimatizing, this drastically reduces CO2 levels.

During sleep, this drop in CO2 levels can reach a threshold and turn off your body's drive to breathe until it further senses a drop in oxygen levels, signaling your body to breathe again.

Contrary to popular belief, the drive to breathe is mainly influenced by levels of carbon dioxide (CO2) in the blood and not the need for oxygen.

"I tried using the Altimate mask 2 weeks prior to climbing Kilimanjaro to get used to the mask. Initially I hated it, I found it fairly comfortable but had a lot of difficulty exhaling with it on and could not fall asleep wearing it.


On the third day of the climb I had a fairly strong headache and could not get rid of it. I decided to try using the mask and it helped me not only get rid of the headache and control my breathing, but it also helped me fall asleep. For the rest of the climb I slept with the mask on and did not suffer from anymore symptoms of AMS."
