Skiing, snowboarding, mountain climbing and snow-mountain biking season is at its peak during the winter holidays for athletes and tourists alike. When a person travels from sea level to 7,000 feet and immediately goes running, skiing, snowboarding, climbing or mountain biking, he/she has the potential to develop early symptoms of altitude sickness. This condition is insidious and can affect some athletes at altitudes low as 5,000 feet. Many athletes are familiar with the effects of flying, but this condition also can happen in a car or on skis. Quickly climbing to 10,000 feet, one can develop headaches and sleeping problems; the first signs of altitude sickness.
To give you a reference point, mountain peaks in the United States range from 8,000 feet to 14,000 feet. Extreme hikers/trekkers tackle the Swiss Alps or mountains in Nepal at a range of 12,000 feet to 15,000 feet. Extreme mountain climbers achieve climbs beyond 15,000 feet, such as Mt. McKinley in Alaska and Mt. Everest at 29,028 feet - the highest peak in the world.
Causes of Altitude Sickness: Western Perspective
The direct cause is thin air, or a decreased amount of available oxygen. The air at sea level is compressed by the weight of all the air above it. As an individual travels from sea level and increases in altitude, the air pressure drops, and the air's density decreases. If an individual reaches 18,000 feet, the molecules are so spread out that he or she is inhaling 50% less oxygen compared to sea level.
The physiological effects include the lungs taking in less oxygen. Thus, less oxygen is available to transfer into the blood, tissues and organs. In serious conditions the body develops a form of hypoxia, or lack of oxygen, which can prove fatal.
The body counterbalances oxygen starvation by increasing heart and respiratory rates, causing more blood to be pumped through the body. Chemical changes in the blood allow more oxygen to be released into the body tissues. One of the drawbacks is that some cells tend to accumulate fluids (especially those in the hands, feet and face). More serious fluid retention is associated in the lung spaces, where the gas exchange of carbon dioxide for oxygen takes place. This is called high-altitude pulmonary edema, which develops within the first two-to-four days of rapid climbing or ascents over 8,000 feet. Another more serious condition is brain swelling, or high-altitude cerebral edema. Both are life-threatening complications of altitude sickness.
Causes of Altitude Sickness: Eastern Perspective
The three patterns are affected as qi, blood and body fluids according to traditional Chinese medicine. First, the spleen qi becomes deficient, while the blood is also deficient. The progression of deficient qi will affect other organs as the stomach, heart and lungs become deficient. The spleen's function of transportation and transformation diminishes and creates accumulations internally, as well as externally contracted wind edema yin or yang, depending upon the pre-existing conditions individually present. If this problem is not counterbalanced, the kidney yang is unable to support the spleen yang. Ultimately, they are unable to support one another. This is severe internal cold, which progresses to yang collapse with liver and heart blood deficiency. In extreme cases, liver blood deficiency progresses to internal wind.
Symptoms
Altitude sickness develops from "mild" to "acute" stages. Mild symptoms can develop within hours by performing a rapid unacclimatized climb, or may show up within a few of days after starting.
Key symptoms:

As the oxygen levels continue to drop, the condition worsens and one experiences a rapid decline of mental/physical abilities, becoming progressively clumsy, lethargic and confused. The individual may start to hallucinate and have breathing difficulties, including coughing and gurgling sounds in the chest. The subject's vision blurs, and the skin starts to turn blue. The acute stage leads to unconsciousness, coma and even death.
Adjusting to the Altitude
There are key steps to remember whenever venturing above 5,000 feet.
a. Rest a day or two before activity
b. Climb slowly - it is the speed at which a person ascends that creates health risks
i. Two to four days after 8,000 feet
ii. Then rest one day for every two days of climbing
c. If above 10,000 feet, travel back down 1,000 or 2,000 feet to sleep (dramatic benefits the first day)
a. Especially if above 7,000 to 8,000 feet
a. After three to four days, if the person is not feeling better, descend immediately to between 2,000 to 5,000 feet.
Mild forms of altitude sickness appear as headaches and/or insomnia, and are frequently harmless and short-lived. Once you have arrived at a particular altitude, it takes about two-to-four days for the body to acclimatize to the thinner air, and the symptoms will disappear. Of course, descending below 5,000 feet will take care of the symptoms, along with tonifying the qi and blood for quick recovery.
Prevention through education means being aware and remembering there is no substitute for common sense. However, there are complementary methods that can possibly prevent or speed up the body's ability to acclimatize to the altitude recovery and prevention.
Eat healthfully
Drink plenty of fluids
Take vitamins on a regular basis and increase certain vitamins beforehand
Studies have indicated that these vitamins and enzymes taken before and during a climb improve the body's ability to remove free radicals, as exercising increases free radical activity. Vitamins C and E are strong antioxidants. CoQ10 increases the body's cellular ability to use oxygen, aids in supporting the spleen/stomach qi, and prevents potential liver qi stagnation.
Increase amounts of tyrosine
Stop every four to six minutes taking 10-12 deep breaths
Avoid alcohol
Participate in mild exercise while waiting to get acclimatized to altitude
Counterbalance qi and blood deficiencies beforehand with acupuncture and herbal formulas.
In conclusion, altitude sickness can be prevented by being aware and educated about altitude differences and how the body responds physiologically (Western) and energetically (Eastern). If an individual does get altitude sickness, steps can be taken synergistically that can provide a speedy recovery without spoiling the fun. For those of you who are snowbirds, be safe and play smart!

Chronic pain afflicts over 20% of the adult population. Sadly, most MDs have essentially no education in treating pain, beyond offering a few toxic medications. Then they tend to steer people with pain away from those health practitioners who are trained. This puts the acupuncture community on the front lines for addressing this epidemic.
When the body is going through a stressful event, the sympathetic system is activated. This activation will help the body with a life-threatening situation. If this state is activated for prolonged periods of time, it starts to consume energy. These traumatic events that generate stressors in the autonomic nervous system (ANS) will eventually become internalized.

One of the things that makes acupuncture so difficult to measure is that the medicine actually does contain some esoteric aspects. There have been numerous studies that demonstrate the neurochemical reasoning behind why acupuncture points stimulate the autonomic nervous system to enact change However, not all the benefits of TCM can easily be measured by randomized, controlled trials. But does that make them fundamentally and definitively untrue?
