7 Tips To Avoid Patagonia Altitude Sickness

If you're planning a trip to this stunning region at the southern end of South America, altitude sickness can put a damper on your Patagonian adventure.
But don't worry! We have years of high-altitude experience to share our top tips with you. With a little preparation and know-how, you can help avoid altitude sickness and enjoy all that Patagonia has to offer.
Here's 7 Tips To Avoid Patagonia Altitude Sickness:

1. Stay well hydrated

It's important to stay well hydrated at all times during your trip. It's estimated by the Wilderness Medical Society that you lose water twice as fast at high altitudes, and increase respiration is a result too.¹¹ 
Common recommendations is to drink half your weight in ounces of water a day. If hiking or climbing, you likely want to drink even more.
TIP: To boost hydration, add sea salt (electrolytes) to your food, and take Zaca hydration chewables to help enhance water absorption.

2. Avoid Overexertion

Don't try to do too much too soon — even simple activities can be exhausting until your body adapts. Strenuous activity such as hiking or climbing can make altitude adjustment harder.
Avoid overexerting your body and take it easy the first few days you go higher in altitude. Rest as needed and take many breaks. 

3. Acclimate Slowly 

Don't try to ascend in altitude too high too fast. Your body needs time to adjust to the change in oxygen levels, this process can take a few day to even a few weeks in severe cases.
For example, El Chaltén is a popular starting point for many hikes but only sits at 1345 feet. If you're going to climb nearly mountains, this is a great place to stay and will ease your increase in elevation before heading to higher points.

4. Get A Good Nights Rest

Research shows that sleep is the secret ingredient to recovery.¹² And it can help increase blood flow and oxygen.¹² This can be vital for high altitudes, while at the same time altitude sickness can counteract and cause sleep issues or insomnia.
Get a good nights rest, 7-9 hours of sleep is optimal. To enhance your circadian rhythms for sleep, get plenty of natural sunlight during the day and sleep in complete darkness.

5. Limit Alcohol 

Before you travel to Patagonia, it's important to know that alcohol consumption can worsen altitude sickness. The results from alcohol include dehydration, lower sleep quality, decreased blood oxygen saturation.¹³
Symptoms of a hangover can be similar as well, including fatigue and headache. Limit alcohol your first day or two a higher altitudes, or until you feel no symptoms of altitude sickness.

6. Take Antioxidants 

Oxidative stress, that causes free radical damage, has been found to be a contributor to the issues a high altitudes.¹⁴ Antioxidants can be a promising solution to help fight it off.¹⁵
One study out of India discovered high altitudes to deplete glutathione by 45%. Supplementing antioxidants can help increase your levels naturally and combat oxidative stress.¹⁶
In conclusion, these top researched tips can help you avoid Patagonia altitude sickness — which includes staying well hydrated, avoiding overexertion, acclimating slowly, getting a good nights rest, limiting alcohol, and taking antioxidants.
