Acclimatization takes place over several days and involves physiological changes in your body that help you adapt to lower oxygen levels increased respiration. At heights like Mexico City, visitors aren't always able to adjust fast enough and therefore experience some forms of altitude sickness.

Here Are 6 Tips To Avoid Mexico City Altitude Sickness:

1. Acclimate Slowly

One of the best ways to deal with Mexico City altitude sickness is to acclimate slowly.

If you're going directly from sea level to Mexico City, your body is going to be in shock from the drastic increase in altitude. The problem is you fly into the Mexico City International Airport that's already 7,349 ft (2,240 m) high.

You should plan on spending several days in Mexico City before traveling any higher up into the mountains or other areas where there is less oxygen available.

This will give your body time to adjust gradually to the new environment and will prevent your body from struggling with low oxygen levels suddenly, which would lead to symptoms such as headaches and nausea from altitude sickness.

2. Get Proper Hydration

Dehydration is one of the main culprits of altitude sickness, so make sure to drink plenty of water while you're traveling in Mexico City. Dehydration can also make symptoms worse if you already have Mexico City altitude sickness.

In addition, the body reacts to high altitudes by increasing respiration which can further leads to fluid loss.

Experts recommend that adults drink about half their body weight in ounces of water. At the high altitudes of Mexico City you should drink even more if possible. The key is to drink enough fluid so that your urine is pale yellow or clear in color.

TIP: To maximize hydration, by taking Zaca Chewables you can increase water absorption and electrolyte intake.

3. Avoid Strenuous Activity

It is also important not to engage in strenuous activity during this adjustment or acclimatization period.

Those who engage in heavy exercise or physical labor may experience symptoms such as rapid heartbeat, shortness of breath, or fatigue and weakness. This can possibly lead to even more serious Mexico City altitude sickness.

Avoid strenuous activity and exercise until you've acclimatized to the altitude. You should know within two days of arrival when you don't exhibit any symptoms of altitude sickness. Once acclimated, you can pick up your activity level.

4. Rest Adequately

Get plenty of rest before and during your trip. Resting adequately when you first arrive in Mexico City can help improve the chances of preventing altitude sickness from developing.

Sleep is essential to the body adjusting and recovering. OrthoCarolina reports that during deep sleep you "will see an increase in blood flow, which brings along oxygen and nutrients that that help recover and repair muscles and regenerate cells".¹⁰

They recommend an adult get 7-8 hours of sleep for adequate rest for recovery.

5. Limit Alcohol

Alcohol and high altitudes are a bad combo. The symptoms of a hangover and altitude sickness are strikingly similar ─ including headaches, nausea, and fatigue.

Limit your alcohol intake the first day or two. Alcohol can dehydrate you and also cause oxidative stress, making it harder for your body to adjust to high altitudes.

6. Supplement Glutathione
