People in the UK are taking an average of 37 minutes to get to sleep each night, while many of them are turning to soothing noises in a bid to help them doze off. The survey, carried out by Chessington World of Adventures in Surrey, discovered that one in five people (20 per cent) say that noises from nature are the best things to listen to, particularly effects from the rainforest or simple birdsong. Meanwhile, waves are considered the most soothing individual sound effect, preferred by 11 per cent of Britons. Soft music, such as classical, came in second with nine per cent. Wind was third with eight per cent, while a ticking clock and late night radio were also enjoyed. Sleep expert Dr Neil Stanley said of the survey: "Listening to sounds you like helps the brain 'tune out' other more disruptive sounds, so you get a better night's sleep. Noises from nature, which tend to provide a continuous, familiar sound which you don't have to actively listen to, can be particularly helpful."
