Yes, it's true: There are health benefits to some of our worst habits. So why does being bad feel so good? "'Bad habits allow us to act like children, which may be a good or a bad thing depending on the circumstances," Dr. Daniel J. Carlat, associate clinical professor of psychiatry at Tufts University School of Medicine, author of Unhinged and the Mental Health Specialist for AOL Health's Medical Advisory Board, told AOL Health. Read on to find out which of your "bad" traits you shouldn't break.
Cursing: Let's face it — saying a few choices words a la Martin Scorsese can feel really, really good when you're fed up, frustrated or just plain angry. But now researchers from Keele University in the United Kingdom have discovered that swearing may have a purpose, since it can help reduce physical pain. In the journal NeuroReport, scientists explained that they asked 64 volunteers to submerge their hands in freezing cold water while repeating their favorite curse word. Afterward, they performed the task again, only this time repeating a nonswear word. The end result: The volunteers could tolerate the icy water longer while using a four-letter word by nearly double the amount of time (two minutes compared to one minute and 15 seconds). While experts could not pinpoint the exact explanation, lead researcher Dr. Richard Stephens and his team believe that throwing around the F-bomb may trigger the flight-or-fight response, which can increase heart rate and aggression and help the body cope with pain.
Blasting your favorite music: When you find yourself being forgetful, go ahead and crank up the Bon Jovi. Researchers at Glasgow Caledonian University in Scotland believe that listening to rock music at a high volume can improve concentration and boost memory. During the study, which was published in the science journal Consciousness and Cognition, psychologists had 16 volunteers of rock music lovers take a simple memory test four times — once listening to classical music, another listening to rock, a third time listening to static and lastly taking in the sound of silence. Study participants showed an improvement in concentration and memory when both types of music were played, but during the rock portion of the test, their brain scans revealed they needed less brainpower to complete the test successfully. Music therapist Kimberly Sena Moore told AOL Health that it's not surprising that rock fans performed better when they heard their favorite tunes in the background. "It could be because listening to music they like put them in a relaxed and happy mood, but we still don't know if that's true." However, Sena Moore does warn against blasting too long or too often. "The hair cells in our cochlea (located in the inner ear) are sensitive and blasting any sort of music, whether at a concert, at home or even through headphones, can damage them and even lead to hearing loss or tinnitus later in life."
