9. High Hemoglobin

As important as hemoglobin is to us, it is possible that we can have too much hemoglobin in our blood. In addition to individual cells having more hemoglobin than usual, our blood can also have too many red blood cells in a condition known as polycythemia.

There are various reasons why these conditions might happen, including but not limited to: poor cardiovascular functioning, being at a high altitude, the use of certain medications, heavy exercise, and malfunctioning bone marrow. Symptoms include being short of breath, exhaustion, headaches, pain in the chest, pale skin, abnormal heartbeat, and cold hands and/or feet.
