1. Proper Hydration

The first step to avoiding altitude sickness is proper hydration.

While this tip might seem like a no-brainer, most people visiting Colorado don't realize they're dehydrated. With the high altitude and dry climate, it's a recipe for faster loss of body fluids. The high altitude in Boulder also causes increase respiration which further leads to dehydration.

At a minimum, you should drink at least half your body weight in ounces of water. 1 ounce per every 2 pounds. That’s a good start, but if you’re planning on activities like climbing mountains and hiking in Boulder, you need even more water.

Make sure to start drinking ample water not only every day of your visit, but days leading up to your trip too.

TIP: To maximize hydration, you can either add sea salt to your drinks or take Zaca's chewable electrolyte tablets that help increase water absorption and electrolyte intake.

Getting rest and taking it easy for your body to acclimate at Boulder's high elevation is key.

This allows your body to adjust to the changing environment where there's less oxygen. It also gives you time to feel better if you start experiencing symptoms of altitude sickness.

Many visitors overdo it their first day or two, leading to an increase risk in altitude sickness. Avoid any strenuous activities your first few days upon visiting Boulder such as hiking. Get adequate sleep before and each day during your trip so your body has enough time to adjust, recover, and acclimate to the altitude.

Lastly if you're planing on visiting the mountains from Boulder, such as Breckenridge, Vail or Aspen — stay at least 1-3 nights in Boulder before moving on.
