High Altitude Health Tips
One veteran MD. who has attended the SSSP has found the following information from a medical awareness pamphlet. He would like to point out that some people get altitude sickness at 7,000 feet, many at 9,000 feet (the base level for many ski resorts). Lake Titicaca is at 12,500 feet and is higher than the topmost mountains at most US ski resorts.
Steps to take to avoid Altitude Sickness:
Prevent Cold Injury
As you ascend to higher altitudes, atmospheric pressure decreases, the air is thinner and less oxygen is available. it is also colder, drier and the ultraviolet rays from the sun are stronger. Each of these changes may have unpleasant effects on your body. Above 8000 feet, altitude illness affects 20 - 30% of visitors from low altitude to some degree. The extent to which you are affected depens on how quickly you ascend, what elevation you attain, how hard you exercise, what you eat and drink and what health problems you may have (smoking, emphysema, asthma, anemia, diabetes, high blood pressure). When planning a trip to an area above 8000 feet, consult with your doctor if you have any questions.
After arriving at high altitude, you will probably notice that your breating is faster and/or deeper, and you may feel short of breath, especially when exercising. This is the body's first and most effective response to higher elevations. In addition, your heart is likely to beat faster, and you may develop mausea, unusual tiredness, headache, or have difficulty sleeping.
Visitors with one or more of these symptoms may have acute mountain sickness (AMS). This form of altitude illness usually resolves in a day or two. If the symptoms become worse, or if you are concerned, be sure to consult a doctor.
A wet cough, increasing shortness of breath or the feeling of fluid collecting in your lungs may signal a more serious condition called High Altitude Pulmonary Edema or HAPE. HAPE requires immediate medical attention.
Before you leave home, you can do a few things to decrease the effects of high altitude. Spending two nights at modest altitude, 5000 to 6000 feet, may decrease symptoms when you ascend. Eating foods which are high in carbohydrates, drinking more water than usual and using less salt may also help.
Diamox is a prescription drug which prevents unpleasant symptoms for many people who may be exceptionally prone to AMS. Our experience suggests the following dose can be effecttive; 250 mg 2 - 3 times a day with meals, beginning 36 hours before arrival to high altitude, continuing for 5-7 days. Diamox should not be taken by people who are allergic to sulfa drugs. Discuss use and possible minor side effects (tingling ssensations, altered taste, increased urination) with your doctor.
Once you arrive, take it easy for the first day or two. Adequate hydration is important in the prevention of altitude illness. Drink two or three times more water or fluid than usual. Limit alcohol comsumption for two or three days and minimize caffeine intake. Limit salty foods and increase carbohydrate consumption. Above all, listen to your body. Do not push the limits of your physical capabilities. If you feel worse, get medical attention! Minor altitude illness symptoms can occasionally become life threatening.
At high altitude the ultraviolet rays from the sun are more intense and, therefore, more damaging. Even when it is cludy, the risk of sunburn is extreme. Before going out for the day, protect yourself and your family from the sun's ultraviolet (UV) protection.
The air temperature falls about three degrees Fahrenheit for every 1000 feet of elevation gain, therefore, temperatures in the high country can drop rapidly. Hypothermia (low body temperature) can occur when you are wet, chilled, fatigued or dressed inappropriately; even during warm weather. Warning signs are confusion, difficulty speaking, irritability and loss of coordination. Bring along extra clothes, drink and eat sufficiently and watch for warning signs in each other. If in doubt, stop, warm up, and take fluid and food, and if necessary send for help.
Frostbite is caused by cold exposure, resulting in ice crystals forming in the skin. It frequently occurs in the extremities, specifically the nose, ears, fingers and toes. The skin becomes numb, firm and yellowish white in color. Rewarming causes tingling and pain with skin color changes and blisters occurring in severe cases. Prevention includes dressing appropriately in winter (layering), wearing boots and gloves that are not wet or too tight, and taking time to warm up frequently.
Consult a doctor for severe cases of any of these injuries due to exposure to cold weather, or if you have any concerns regarding cold injury related problems.
We take these health and safety issues very seriously and expect you will also.
Please take the necessary precautions. We want everyone to have a safe, healthy and happy trip to SSSP.
