Colorado's highest peak rises to a lofty 14,433 feet while some highway passes are over 11,000 feet, making altitude preparation a must. Visitors are often out of breath and their breathing is faster and deeper. Some people develop uncomfortable flu-like symptoms, headache, upset stomach, poor appetite, problems sleeping, or just feeling tired.
To make your adjustment to the altitude easier, stay at 5,000 feet for a day or two before traveling higher. Get a little extra rest and less physical activity in the first few days. Drink more water and do not consume alcoholic beverages, caffeine, or salty foods. Salt causes your body to retain fluid which will increase the effects of altitude sickness. Eat low fat meals and enjoy higher carbohydrate foods. Most of all, listen to your body! Take it easy, enjoy, and don't push yourself. Should your condition be extreme, seek medical assistance.
