noise control Excessive noise may cause a brain tumor
Nothing beats blasting the stereo and grooving to Kanye West. But check your dance sessions: Repeated exposure to excessive noise may increase your risk of developing acoustic neuroma, a noncancerous nerve tumor that grows inside the skull, causing hearing loss and tinnitus (ringing in the ears), according to a study in the American Journal of Epidemiology. A survey of 710 men and women found that those regularly exposed to loud music for a year were 2.25 times more likely to develop a tumor than those with no exposure. "Intense sound damages structures inside the ear, leading to DNA errors during cellular repair that can cause tumor growth," says study coauthor Colin Edwards. Keep your iPod's volume low enough that you can carry on a conversation without shouting.
