Hikers Oxygen: 3 Best Canned Oxygen For Hiking

Hikers Oxygen: 3 Best Canned Oxygen For Hiking

Hikers often venture to higher altitudes and face a significant challenge: reduced oxygen levels. As a company based in the high elevations of Colorado, we'll share everything you need to know about hikers oxygen as an altitude remedy and three of the best oxygen options for hiking.

Hikers Oxygen

Oxygen is a vital element present in our atmosphere, constituting approximately 21% of the air we breathe. But when we ascend in altitude while hiking, the oxygen levels go lower.

Hikers oxygen, or portable oxygen, can be a lifesaver for hikers to potentially providing relief or improvement during high-altitude expeditions.

Altitude Sickness: The Importance of Oxygen for the Human Body

Oxygen is essential for the human body as it fuels the process of cellular respiration, providing the energy needed for bodily functions. From powering physical activity to maintaining brain function, oxygen plays a fundamental role in our overall well-being.

The lack of oxygen, also called hypoxia, while hiking can lead to altitude sickness which includes symptoms such as fatigue, headaches, and nausea.

Symptoms of altitude sickness may include: 

  • headache
  • insomnia or sleeping issues
  • nausea or vomiting
  • fatigue, tiredness, or weakness
  • dizziness or confusion
  • loss of appetite
  • difficulty breathing
  • feeling sick

These symptoms can develop within 4-24 hours of lower oxygen levels when hiking at high altitudes.

Does Canned Oxygen Work For Hiking?

Canned oxygen might work for hiking.

There's conflicting evidence for effectiveness, as supplement oxygen or oxygen tanks are proven to be affective for altitude sickness.¹ However, canned oxygen which are much smaller are shown to help aerobic exercise but no direct research proving it helps with altitude sickness.²

A study done on the physiological effects of boost oxygen canisters found it can be beneficial to active individuals, trainers, and athletes for exercise and to improve VO2.²

In conclusion, canned oxygen (hikers oxygen) is effective for hiking in regards to body for exercise purposes and athletic performance, but likely not to help with altitude sickness.

How Do You Use Oxygen While Hiking?

To use oxygen while hiking, you'll simply inhale deeply for 1-3 seconds, then exhale. Boost Oxygen instructs to do this 3-5 times as needed.

For the aerobic aspect of hiking, this should be sufficient to use the oxygen in intervals as you feel needed. For altitude sickness, it appears that canned oxygen would not be enough quantity of oxygen to make a difference.

The Next Summit mountain blog did some research estimating that you'd need a canister (10-liter) of oxygen every five minutes to help altitude sickness.³ Based on their findings, you would need a lot of hikers oxygen cans to get adequate results.

At What Altitude Do You Need Oxygen When Hiking?

For aerobic improvement, canned oxygen can be beneficial for hiking at any altitude.

Hiking difficulty from high altitude can start at around 4,000 feet and increase with ascending elevation.⁴ This is based on the fact that at 4,000 feet, altitude sickness could start according to Travel Medicine Consultants. At these heights oxygen levels start decreasing, making supplemental oxygen potentially beneficial.

Oxygen Levels Based On Altitude:¹⁰

  • 2,000 Feet - 7% less oxygen than sea level
  • 4,000 Feet - 14% less oxygen than sea level
  • 6,000 Feet - 20% less oxygen than sea level
  • 8,000 Feet - 26% less oxygen than sea level
  • 10,000 Feet - 31% less oxygen than sea level
  • 14,000 Feet - 41% less oxygen than sea level
  • 18,000 Feet - 41% less oxygen than sea level
  • 18,000 Feet - 50% less oxygen than sea level
  • 24,000 Feet - 60% less oxygen than sea level
  • 24,000 Feet (Mt. Everest) - 77% less oxygen than sea level

Based on the list above, you can see the risk of lower oxygen levels goes up dramatically as you ascend in height. More oxygen is necessary for each altitude level, until you're acclimated.

Can You Take Canned Oxygen On A Plane?

No, due to FAA rules, you cannot bring any kind of oxygen on the plane or in checked baggage.

No matter whether checked baggage or carry-on baggage — canned oxygen, recreational oxygen, and flavored oxygen are all prohibited.

With such restrictions, we'd recommend taking a high-altitude or hiker supplement (as below), which usually can be taken on the plane when in pill, tablet, or chewable form.

How Long Does A Can Of Oxygen Last?

According to Boost Oxygen, you can get a a range between 60 to 200 seconds of oxygen based on the canister size.

How Long Can Of Oxygen Will Last:⁹

  • 3 Liter Oxygen Canister - 60 one-second inhalations
  • 5 Liter Oxygen Canister - 100 one-second inhalations
  • 10 Liter Oxygen Canister - 200 one-second inhalations

This is how long you can expect your can of oxygen, or hikers oxygen, to last based on the canister size.

Powerful Nutrient For High Altitude Hiking

High-altitude hiking is an exhilarating adventure, often pushing hikers to their limits, however, the decreased oxygen levels has been shown to cause oxidative stress on the body.¹⁷ ¹⁸ ¹⁹

  • Glutathione, the body's master antioxidant, was shown to deplete at rates up to 45% from high altitude exposure.¹⁹

Supplementing antioxidants is shown to be a promising solution.¹⁸ Glutathione particularly is a powerful nutrient and antioxidant to fight free radical damage from oxidative stress.
