Visiting Inka City and Word Heritge Site Machu Picchu ,one of the wonders of the World.
Drinking cocatea in Cusco is situated at an altitude of 3400 meters. At altitudes in excess of 3000 meters, there is half the oxygen in the air compared to sea level, and in addition the air is extremely dry. This means that with every breath they take visitors to Cusco who live at or near sea level inhale less oxygen than they are accustomed to. For this reason, travelers find themselves experiencing shortness of breath when walking, particularly when walking uphill.
Altitude sickness does not affect all visitors to Cusco, and susceptibility to altitude sickness is not dependent upon age, gender, or physical condition. However, people with heart or lung problems are at a higher risk. Symptoms may include headache, difficulty breathing, nausea, vomiting, dizziness, diarrhea or constipation.
One tip that visitors will probably only hear in Cusco is to drink coca tea, which is an infusion made from coca tea leaves. Most of the
hotels in Cusco offer their guests coca tea. Although it has not been scientifically proven that coca tea combats altitude sickness, many travelers have found that it certainly provides relief from the symptoms. In Cusco, the coca leaf is also available in candy, cookies and brownies. Local people, particularly in rural communities, chew coca tea leaves.
