The mountains of Colorado are among the most beautiful parts of the United States and we hope you enjoy every minute of your visit. However, some of the very features that make this area so attractive may also cause you problems, unless you are able to recognize the symptoms and know how to prevent them

 ALTITUDE ILLNESS

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 to 30% of visitors from low altitude to some degree. The extent to which you are affected depends 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 and high blood pressure). When planning a trip to an area above 8000 ft. consult with your doctor if you have any questions.

After arriving at high altitude, you will probably notice that your breathing 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 elevation. In addition your heart is likely to beat faster and you may develop nausea, 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 a small dose can be effective: 125 mg twice a day beginning 24 hours before arrival to high altitude. Diamox should not be taken by people who are allergic to sulfa drugs. Discuss use and possible minor side effects (tingling sensations, 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 consumption 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, seek medical attention! Minor altitude illness symptoms can occasionally become life threatening.

SUN INJURY

At high altitude the ultraviolet rays from the sun are more intense and therefore more damaging. Even when it is cloudy the risk of sunburn is extreme. Before going out protect yourself and your family from the suns ultraviolet rays. Apply a sunscreen SPF 15-30 to your skin before beginning outdoor activities and every two hours while outside.

To prevent sun injury to the eyes, wear sunglasses or goggles with (UV) protection.

COLD INJURY

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, take fluids 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. If you have any concerns regarding cold injury related problems please contact a High Country Health Care, P.C. facility.

Welcome to Colorado, where the mountains rise and cakes fall, where the wheat spreads across the plains and the cookies across the pans. Cooking in Colorado can be a challenge but with a few tips it can be mastered. Our higher altitude means lower atmospheric pressure due to the thinner blanket of air above. There is about 1/2 pound less pressure for each 1,000 feet increase above sea level. This decreased pressure affects food preparation in two ways: 1. Water and other liquids evaporate faster and boil at lower temperatures. (It's not your imagination - the coffee really isn't as hot as it was in Atlanta.)
2. Leavening gasses in breads and cakes expand more. At sea level water boils at approximately 212 degrees F. In the Denver area, water boils at around 203 degrees F. Therefore, cooking food in boiling water takes longer.

Canning
This is usually not a problem unless you're canning food. Time or temperature must be increased in order to kill heat-resistant bacteria. A steam pressure canner must be used for canning meats and vegetables. Follow high altitude directions available from all County Extension Offices.
 

Deep-Fat-Frying
When deep-fat-frying, lower the temperature of the oil about 15 degrees here to prevent food from over-browning on the outside while being under-cooked on the inside. Baking casseroles and meats require no changes.

Cake From Scratch

Are you ready for the real challenge? A cake made from scratch! If not, continue to use box mixes and follow the high altitude suggestions. For those with sense of adventure, read on.

Above 3,000 feet in altitude the lower atmospheric pressure will affect cakes. There may be excessive rising which stretches the cell structure of the cake, making the texture coarse, or the cells can break before they set causing the cake to fall. This can usually be corrected by decreasing the amount of leavening agent and by increasing the baking temperature 15 degrees to 25 degrees. Because water in the batter evaporates quicker here, there is more of a concentration of sugar in the recipe which weakens the cell structure. Therefore we usually recommend decreasing sugar and increasing liquid. The cakes most likely to fall are those wonderful sweet, sticky, gooey rich ones. These super rich cakes may require reducing shortening by 1 or 2 tablespoons or by adding an extra egg. Some recipes will work fine without changes, others will take some experimenting. Here's a table* to give you a starting point.

Adjustment

3,000 ft.
5,000 ft.
7,000 ft.
Reduce baking powder, for each tsp., decrease 1/8 tsp. 1/8-1/4 tsp. 1/4 tsp.
Reduce sugar, for each cup, decrease 0-1 Tbsp. 0-2 Tbsp. 1-3 Tbsp.
Increase liquid, for each cup, add 1-2 Tbsp. 2-4 Tbsp. 3-4 Tbsp.
* Table fromHigh Altitude Food Preparation- pamphlet 41

Angel food and sponge cakes use air for leavening. It comes from beating air into the eggs. Beat only until they form peaks that fall over - not stiff and dry, which cause the cells to collapse. Again, use less sugar and more flour and a higher baking temperature. We're often asked why we don't just add more flour and water to cake recipes like they do with box mixes. Isn't this more complicated. Have you ever tried to take some of the leavening or sugar out of a box mix? The only option on a box mix is to strengthen the cell walls by adding flour and water.

For more information on baking at high altitudes, ask for "High Altitude Food Preparation" Pamphlet 41 from your Colorado State County Extension Office. There is no charge. It will also list other high altitude recipe books available from Colorado State Cooperative Extension.
