High hemoglobin level is most often caused by low oxygen levels in the blood (hypoxia), present over a long period of time. Common reasons includes bone marrow disease that causes abnormal increase in red blood cells (polycythemia vera) Congenital heart disease and heavy smoking.
High hemoglobin levels can lead to dizziness, fatigue, easy bruising and other symptoms.
Sleeping at higher attitudes promote fitness as it provides enough exposure to stimulate the production of new red blood cells, whilst allowing you to maintain training quality at sea level.
