How Do You Reduce Your White Blood Cell Count?

Lowering white blood cell counts is best accomplished by treating the underlying cause. Quitting smoking and reducing stress levels may lower white blood cell count, according to MedlinePlus. Controlling inflammatory diseases, such as allergies or rheumatoid arthritis, and treating infections can also decrease the number of white blood cells.

An elevated white blood cell count, called leukocytosis, is sometimes caused by medications such as albuterol, corticosteroids and lithium, notes MedlinePlus. Individuals should speak to their doctors about alternative treatments if they are concerned about medications causing an elevated white blood cell count. Leukemia, anemia and tissue damage may also cause leukocytosis. White blood cell counts typically return to normal when these conditions are treated.

Strengthening the immune system and preventing infections is important in order to maintain normal white blood cell counts. Eating a diet high in fruits, vegetables and nuts provides the immune system with the nutrients it needs to maintain optimal health, explains Mother Earth News. Avoiding juices and sugary foods is also recommended, as these can weaken the immune system. Maintaining a regular exercise schedule, getting enough sleep and enjoying a good social life boost immune function. Taking a probiotic supplement and making sure to get enough vitamin D also help keep the immune system strong.
