Blood pressure is subject to fluctuations during the day even
in healthy people. The fluctuations are influenced by a number of
factors – time of day, person’s condition, physical or mental activ-
ity, environment, etc.
Day-Night Fluctuations of the Blood Pressure
An increase of blood pressure increases the burden onto the
heart, affects blood vessels making their walls thick and less elas-
tic. One of the features of the hypertension is its ability to remain
unnoticed for the patient at its early stages. That’s why the self-
control of the blood pressure is so important. With the illness
progressing, headaches and regular dizziness appear, the sight
declines, the functioning of vitalses (encephalon, heart, kidneys,
blood vessels) breaks down. Without special treatment the com-
plications of hypertension might be kidney damages, breast-pang,
paralytic stroke, aphasia, dementia, heart attack and stroke.
