Sleep is vital for older adults, as it allows their body to repair itself and prepare for the coming day. However, those that live in urban areas may not be getting as much rest as they should. According to a recent US study, those exposed to high noise levels are at risk of sleep disturbances or experiencing feelings of annoyance. This has serious health implications, especially in terms of mental stability. Dr James B Holt, co-investigator on the study, explained: "Our research estimated that the percentage of the overall populations at risk of high annoyance is 9.5 per cent, and highly disturbed sleep at 2.3 per cent." He added that noise exposure over a long period of time could increase the risk of a heart attack, high blood pressure and insomnia. While more research is needed into the implications of city noise on sleep and overall health, the findings initially indicate the importance of sound proofing for getting a restful night's sleep.
