Several factors can influence blood viscosity, including:
Dehydration: Lack of fluids can thicken the blood. Temperature: Blood tends to become more viscous at lower temperatures. Hematocrit levels: Higher concentrations of red blood cells increase viscosity. Protein levels: Elevated levels of plasma proteins like fibrinogen can thicken the blood. Medications: Certain drugs can affect blood viscosity either by thinning or thickening the blood.
