3 Tips To Avoid Keystone Altitude Sickness

If you plan on visiting Keystone for a ski trip or summer vacation, you should know about altitude sickness.

The good news is that there are ways to prevent altitude sickness from occurring when you travel to high-altitude destinations like Keystone. Being based in Colorado, we do a lot of research in this department.

Here are three tips to avoid Keystone altitude sickness:

1. Stay Well Hydrated

One of the best ways to avoid altitude sickness is to stay well hydrated. Dry, high altitude climates can cause dehydration and lead to worsening altitude sickness symptoms.

When traveling to the high altitudes of Keystone, make sure you drink plenty of water every day. Drinking enough water will help keep your body from becoming dehydrated. Experts recommend at least half your body weight in ounces of water.

Avoid alcohol, at least on your first day or two, which can make dehydration worse.

TIP: Use sea salt in your foods or water to add electrolytes and enhance hydration. Or take Zaca's hydration chewables to increase water absorption and electrolyte intake.

2. Take Altitude Supplements

Certain vitamins and supplements can help replenish the body with high altitude friendly nutrients.

Altitude supplements come in various forms, such as altitude sickness tablets and high altitude pills. If you're no accustomed to high elevations, altitude supplements are a great option.

It's usually best to start take an altitude supplement between 1-2 weeks prior to your trip, and every day during.

Based on our company research, these 2 ingredients have altitude-related studies:

1. Glutathione - Know as the body's master antioxidant, Glutathione was shown in a 2001 study to be depleted by high altitudes, up to 45%. Replenishing glutathione via supplementation can help increase your levels.²

2. DHM (Dihydromyricetin) - A known herb in Traditional Chinese Medicine extracted from Japanese Raisin, a study revealed it to enhance performance at high altitude. DHM can be an effective herb to supplement for high altitude trips.³

The combination of these study-backed nutrients can aid your Keystone altitude trip.

3. Acclimate and Don't Overexert

Avoid overexertion while at high altitudes because it can make altitude sickness worse by increasing breathing rate and heart rate — both of which put additional strain on the body.

This means resting the first 1-3 days of your trip, and getting ample sleep. If you're planing to ski, snowboard or any other outdoor activities like hiking, you want to be confident that you're not developing altitude sickness symptoms before starting.

As with any kind of physical exertion at high altitudes, it's important not to overdo it when exercising at high altitudes because this can lead to exhaustion and dehydration which both contribute to altitude sickness symptoms like headache and nausea.

On average it can take a few days to acclimate or see altitude adjustment. For severe cases, it can take up to 2 weeks. Try to acclimate best as possible before attempting intense activity.

To help acclimate, many visitors coming from sea level will stay in Denver at 5280 feet in altitude for a night or two before heading to Keystone. By going up in altitude in increments such as this, it will help your body acclimate better.
