Oxygen bars are a novelty in Colorado and are not intended to treat any medical condition. Renting an oxygen concentrator from a non-medical company—without a prescription or a medical assessment from a licensed provider—is a dangerous practice. These services are unregulated, and improper use can lead to worsening AMS or other life-threatening conditions that can mimic AMS.

These products are sold in many Colorado stores as a novelty, but they will not help with AMS.

If your urine is clear to pale yellow, you are well hydrated. Drinking excessive water or receiving IV hydration when already well hydrated can cause dangerous electrolyte imbalances and may worsen certain chronic medical conditions.

Being athletic does not protect you from AMS; in fact, high levels of exertion at altitude can increase your risk for HAPE.

Previous successful trips to altitude do not guarantee protection from altitude illness on future visits. Even people who were born and raised at high altitude, or who have previously acclimatized without issues, can develop altitude illness if they return to high elevations after spending time at lower altitudes or sea level.

In reality, healthy individuals over age 50 are at lower risk for AMS. Anyone—from babies to the elderly—can develop AMS.

Diamox does not simply hide symptoms—it actively speeds up your body’s natural acclimatization by stimulating breathing and helping you adapt to lower oxygen levels. It is one of the main medications used to prevent and treat acute mountain sickness (AMS) and does not cause rebound symptoms if stopped.

Caffeine, in moderation, is safe to use at altitude. It can help with acclimatization by stimulating breathing and alertness. Avoiding caffeine abruptly may even cause headaches, especially for regular users.

Alcohol does not help with acclimatization and can actually worsen dehydration and impair your body’s ability to adapt to altitude. It should be avoided, especially in the first 24–48 hours at high elevation.

Altitude illness is a physiological response to low oxygen, not a test of mental strength. Ignoring symptoms or pushing through severe illness can lead to life-threatening complications. The safest response to worsening symptoms is to stop ascending or descend.

Symptoms of AMS can develop at elevations as low as 4,000 feet (1,200 meters), though they are more common above 8,000 feet. Anyone ascending rapidly to moderate elevations should be aware of the risks.
