“Mozart effect”, or can music make you smarter?

Музыка ноты
Much has been written on the “Mozart effect” - the theory that classical music can stimulate the listener's brain and make them cleverer. Further studies however have refuted the finding and have allegedly proved that the only real benefit to be gained from listening to music is pleasure. It now seems that this enjoyment could be of particular importance where health is concerned.
The “Mozart effect” has long been used as a marketing ploy to sell educational toys or child development materials such as CDs and DVDs. The basic idea was that children who listened to Mozart's music received a "brain boost" to improve their IQ. However, this theory is little more than a medical fairytale. According to Dr. Jessica Grahn, a cognitive scientist at Western University in London, Ontario: “The Mozart effect is a media-driven myth. One study in 1992 showed that undergraduate students who listened to Mozart before a test did better than students who sat in silence or listened to a relaxation tape.” Despite its appeal, the effect has never been confirmed by further studies. As Jessica Grahn said in an interview with the ‘Voice of Russia’: “Later studies showed that this improvement probably had nothing to do with Mozart at all, but instead happens anytime we do something that boosts mood and arousal.” In fact a beneficial effect might indeed be obtained from listening to Mozart; but other kinds of music have been shown to work just as well. What matters is the listener's taste. Dr. Glenn Schellenberg, a psychologist from the University of Toronto, said in an interview with the ‘Voice of Russia’ that: “It doesn’t matter if it's Mozart or Schubert. It is just that music makes you feel good. You can get lots of different effects like that with different kinds of stimulus, which make the listeners feel better.” A study on young children has shown, for example, the "Blur effect" similar to what Mozart was thought to achieve. The effect of music is not related to a specific musical genre. Dr. Glenn continued: “We’ve observed that with 9-11 year old children, pop music works better and on 5 year old kids, children's music works better. It actually depends on the listeners; on which music is going to make somebody feel good. The effects can be noticed with every kind of music, but not if the listener hates it!” Enjoyment is the key; examining the brains of people who were listening to music, scientists have discovered that, while the main effect is pleasure, movement is also involved. Dr. Grahn underlined that: “Several studies have shown that 'reward' areas of the brain, areas that respond to pleasurable things like food or sex, also respond when listening to pleasurable music, particularly if it is music that can give you chills”. Music makes you feel good, but it also makes you move, as Grahn added: “I have also found that when people listen to music, areas of the brain that are responsible for controlling movement are active. This suggests music engages our movement systems, even if we're staying perfectly still.”  Even so, music impacts ordinary listeners and musicians differently. As Jessica Grahn observed: “Many responses are similar across listeners and players. However, players sometimes show more responses in movement areas, perhaps because they are imagining playing along.” Moreover, several studies have proved that playing music regularly can improve IQ by a few points. Although listening to music doesn’t actually boost intelligence, it does make you feel good and in that way influences every aspect of life. Dr. Glenn Schellenberg observed that the effect of music on feelings should not be underestimated: “If you talk about a ‘mood effect’, you’re discounting the power that music has on well-being and health in general.” Music can have a crucial impact on health. “If people undergo an operation, if they’re listening to their favourite CD, then they need less medication. There are lots of examples of effects of music on health, and on well-being more generally. Music makes people feel good and how you feel really has a huge impact on every aspect of life,” Schellenberg stressed. The use of music as a complementary therapy is developing. Music is being utilised in hospitals and clinics around the world. More and more charities organise concerts in hospitals. Members of the British NGO“Music in Hospitals” play for patients all over the UK. Music can often minimise pain and increase a patient's well-being. For example, when people undergo surgery, the use of music as a part of their treatment eases anaesthesia, and helps to speed up the healing process.  Although music has no real impact on intelligence, it does seem to have an important role to play as a therapeutic tool which will probably boost your health, but probably not your IQ! Eva BertrandSource: Article

Energy drinks start to destroy teenagers' teeth after 5 days: Study


Energy drinksTeenagers, the next time you down an energy drink, do give a second thought, for an Indian-origin researcher-led study claims these beverages start to destroy teeth after only five days of continuous consumption. In their study, Dr Poonam Jain at Southern Illinois University and colleagues charted an alarming increase in the consumption of both energy and sports drinks among young adults in the US. They said the habit is causing irreversible damage to teeth as the high acidity levels in the drinks erode tooth enamel, the glossy outer layer of the tooth, the 'Daily Mail' online reported. "Young adults consume these drinks assuming that they will improve their sports performance and energy levels and that they are 'better' for them than soda. Most of these patients are shocked to learn that these drinks are essentially bathing their teeth with acid," said Dr Jain. In fact, researchers examined the acidity levels in 13 sports drinks and nine energy drinks. They found that the acidity levels can vary between brands of beverages and flavors of the same brand. To test the effect of the acidity levels, the researchers immersed samples of human tooth enamel in each beverage for 15 minutes, followed by immersion in artificial saliva for two hours. This cycle was repeated four times a day for five days, and samples were kept in fresh artificial saliva other times. "This type of testing simulates the same exposure that a large proportion of American teens and young adults are subjecting their teeth to on a regular basis when they drink one of these beverages every few hours," Dr Jain said. The researchers found that damage to enamel was evident after only five days of exposure to sports or energy drinks, though energy drinks showed a significantly greater potential to damage teeth than sports drinks. In fact, they found that energy drinks caused twice as much damage to teeth as sports drinks. Damage caused to tooth enamel is irreversible, and without the protection of enamel, teeth become overly sensitive, prone to cavities, and more likely to decay. The findings have been published in the 'Academy of General Dentistry' journal. Source: Indian Express
