LONG TERM EX­PO­SURE TO HONK­ING TRAF­FIC CAN MAKE YOU OBESE

A showed that a 10 deci­bel in­crease in mean noise level was as­so­ci­ated with a 17 per cent in­crease in obe­sity. “Our anal­y­sis shows that peo­ple ex­posed to the high­est lev­els of traf­fic noise are at greater risk of be­ing obese” said Maria Fo­raster, lead re­searcher from the Barcelona In­sti­tute for Global Health in Spain.

It could be be­cause noise gen­er­ates stress and af­fects our sleep. It al­ters hor­mone lev­els and in­creases blood pres­sure. More­over, among other ef­fects, sleep dis­tur­bance dereg­u­lates glu­cose me­tab­o­lism and al­ters the ap­petite, the researchers ex­plained.

“In the long term, th­ese ef­fects could give rise to chronic phys­i­o­log­i­cal al­ter­ations, which would ex­plain the proven as­so­ci­a­tion be­tween per­sis­tent ex­po­sure to traf­fic-re­lated noise and car­dio­vas­cu­lar dis­ease or the more re­cently dis­cov­ered as­so­ci­a­tions with di­a­betes and obe­sity,” Fo­raster said. “Our find­ings sug­gest that re­duc­ing traf­fic-re­lated noise could also be a way of com­bat­ing the obe­sity epi­demic,” he noted. For the study, the researchers in­volved 3,796 adults and ex­am­ined body mass in­dex, waist cir­cum­fer­ence, body fat, cen­tral obe­sity and over­weight.
