24*7 BP tracking provides extra details on how your modifications in BP may correspond with your everyday routines and sleeping habits. For most people, systolic BP declines by about 10%-20 percent during sleep. However, for some people, BP may not fall during sleep and may even rise. BP monitoring can identify abnormal BP fluctuations that may go unnoticed when BP is only evaluated in the hospital. It is a very beneficial way of detecting white coat hypertension, hooded hypertension, and consistent hypertension.
