10 bad things are good to you by Marie Cleland

1. Listening to Loud Music..

If you despair over the thumping soundtrack blasting from your teen's room, you may be surprised to hear it could be doing him some good.
There's scientific proof that the greater the music's intensity the more pleasure it brings, according to research from the University of Manchester.
It's all down to the vestibular system, which is responsible for balance but also carries vibration; when sound waves set it off, it sends a positive massage to the brain. Study author Neil Todd believes it's a hangover from a primitive acoustic sense connected to basic drives such a hunger and sex. Todd found that while sounds carried across a room had to be louder than 90 decibels ( equivalent to a motorbike or lawnmower ) to produce the vestibular response, sounds carried through mass - such as a floor or learning against a speaker - need only be 30 decibels to achieve the same sensation.

In reality, clubs and rock gigs can reach over 100 decibels. Bradford Backus, an expert on music and hearing loss at the University College London Hearing Institute, says the longer you listen to to the loud music, the more damage you do. It's considered safe to listen to 85 decibels for 8 hours, but it if increases to 88 decibels, you should have to length of time.
