4 Tips How to Avoid Flagstaff Altitude Sickness

If you're planning on traveling to Flagstaff or anywhere else in the mountainous regions of Arizona, it's important that you know what to do to prepare.

As an altitude-based company, we have in depth experience and research on high altitudes. From hydration to altitude supplements, we'll cover all the top tips so you can enjoy your Flagstaff trip.

Here Are 4 tips How To Avoid Flagstaff Altitude Sickness:

1. Acclimate Slowly

The best way to avoid altitude sickness is to spend time in Flagstaff before doing anything strenuous.

If you're flying into Phoenix or another low-elevation area, don't go straight from the airport to hiking or skiing in the mountains. Spend a day exploring downtown or other areas of Phoenix. At 1,086 feet (331 m), this gives your body a small gradual change in altitude.

Once in Flagstaff, you'll want a least 1-2 days to acclimate before going any higher in altitude at the ski resorts or surrounding hiking trails. Acclimating slowly gives you time to physically adjust to the higher altitudes.

2. Maximize Hydration

It’s important that you stay hydrated while visiting Flagstaff because dehydration can lead to fatigue and headaches.

Another way that altitude affects your body is by dehydrating it faster than normal due to increased respiration rates at higher elevations.

Dehydration also makes it harder for your body to adjust to low oxygen levels at higher elevations so staying properly hydrated will help keep any symptoms from getting worse.

Experts typically recommend drinking at least half your body weight in ounces of water. We'd recommend more if you're doing more physical activities at Flagstaff altitudes.
TIP: To maximize hydration, add sea salt to your water/foods or take Zaca's chewable electrolyte tablets.

3. Get Proper Rest

Often overlooked, but rest is often your best weapon against Flagstaff altitude sickness.

Take it slow when you first arrive. Get proper rest and sleep your first few days.

Altitude sickness can also cause insomnia and this may affect your performance. Sleep is utmost important to allow your body to adjust and recover to the Flagstaff elevations. At least 7 hours of sleep is essential.

You'll know you've had proper rest when you're very energized during the day. With the lack of altitude sickness symptoms, that's a good sign your body is adjusting well.

4. Take Altitude Supplements

Most Flagstaff visitors don't know that altitude supplements are available to help enhancement your body's altitude adjustment.

There's proven amino acids and herbs for altitude adjustment. Glutathione is one amino acid that has been shown to be affected by high altitudes.

  • Glutathione - A 2001 study showed Glutathione to be depleted by nearly 45% from high altitude conditions.³ Supplementing glutathione can help replenish this lost amino acid and master antioxidant to fight oxidative stress.
Take altitude supplements to help fuel your body for the high Flagstaff altitudes.
