Apart form the psychic and emotional factors, blood pressure goes up because of the vitiation of vayu. Both the psychic and physical factors including climate are responsible for this morbidity.

Blood is pumped by the heart to all parts of the body through the arteries its branches and numerous capillaries. When the heart contracts, blood is forced into the arteries and thus, exerts a positive pressure on the walls of these channels. When the heart dilated, the pressure in the arteries is reduced and a negative pressure is created. The walls of the arteries are elastic to accommodate both positive and negative pressures. During contraction of the heart, the pressure exerted on the walls of the arteries is called systole pressure, and during dilatation of the heart, the pressure exerted is called diastolic pressure.

Blood pressure varies from person to person depending upon age, sex, physical and mental work. Males, those who are aged and those who are exposed to more mental and physical work normally maintain higher blood pressure than others. In physiological conditions, blood pressure increase during fear, anger and excitement. A person during sleep and period of rest maintains a lower blood pressure.
