Eat properly to prepare your body for a change in elevation.
Changes in elevation affect the body when going from a low altitude to a higher one. This can cause a number of problems because of differences in air pressure, temperature and oxygen levels. Preparing your body for a change in altitude helps it acclimate and keeps you safe, while out in the elements. You can protect your body by getting physically fit, dressing appropriately and keeping yourself properly nourished.
Instructions
1. Have a physical to make sure your body is in healthy condition. Changing to a higher altitude can cause altitude sickness, resulting in symptoms like shortness of breath, headache and fatigue. These can be dangerous to those with asthma or pulmonary problems. Bring extra supplies of your prescription medications, such as inhalers or insulin, if necessary.
2. Limit activities such as running, skiing or hiking, until your body acclimates to the change in elevation, as this can cause dizziness and fatigue which can become disorienting. Increase your activity over two to three days, allowing your body to gradually adjust.
3. Dress in layers or pack lightweight and heavyweight gear, expecting weather changes throughout the day, based on the season and elevation. Wear less layers during the daytime hours when temperatures peak. Add layers and protective gear such as coats, snow pants, gloves, hats, face masks, scarfs, thermal clothing and warmers after sundown, when temperatures drop.
4. Apply sunscreen and lip balm, and wear sunglasses to protect yourself from the ultraviolet rays of the sun and to prevent chapping or burning. There is less water vapor in the air at higher elevations, meaning the sun's rays are more intense.
5. Drink water to stay hydrated. Changes in elevation cause your body to lose fluids because the air is drier at high elevations. Double your typical water intake.
6. Avoid drinking alcoholic beverages and using tobacco products. These increase the rate of dehydration and can effect balance and breathing. The blood is thinner at high altitudes, meaning the effects of alcohol and tobacco substances are more extreme.
7. Eat foods that contain carbohydrates such as granola, crackers and bagels. Avoid high-fat foods because they require the body to expend more oxygen to digest them and oxygen is already limited at high altitudes.
