Noise may be a common cause of sleep loss. A recent study by European researchers, in which the Blood Pressure (BP) and bedroom noise level of 140 people who lived near major Air-ports were monitored, finds that in addition to being a nuisance loud noise can be bad for your health. It was revealed that when subjects were exposed to noise at 35 DB or higher (eg: plane flying over head) it lead to a significant rise in Blood Pressure, and that the increase in BP correlated with the intensity of the noise. The above incidents occurred whether or not the subjects were awakened by it.
