Classical music doesn’t make babies smarterAfrica Studio/Shutterstock
Forget the Baby Einstein DVDs. Although actually learning an instrument has been shown to benefit children’s brains, the “Mozart effect“—the idea that playing classical music while your newborn sleeps will boost his IQ—has not. “The idea was that if babies listen to music composed by Mozart, they would have a brain boost, so plenty of products quickly became available to offer such experiences for parents to give their children a mental edge from the start,” Dr. Chapman says. “Nonetheless, listening to Mozart will not do your babies, children, or you any harm and may build a lifelong appreciation for music—other music will achieve that as well.” These are the other incredible ways classical music makes you healthier.
Alcohol doesn’t actually kill brain cells279photo Studio/Shutterstock
Another brain myth most of us believe is that drinking alcohol kills brain cells. Alcohol does take a toll on your body and brain, but it’s not the number of brain cells that are diminished with alcohol consumption—instead, it’s actually the production of new cells that’s impacted, according to research. A recent study from the UK found even moderate amounts of alcohol to have negative long-term damage on cognitive functioning. Here are more health benefits of quitting alcohol.
Multitasking interferes with the brain’s performanceRawpixel.com/Shutterstock
If you think doing multiple things at once shows your smarts, you might be mistaken—research has shown that multitasking only causes us to take longer to do each task. “Multitasking hijacks your frontal lobes, the brain’s higher-order thinking center,” Dr. Chapman says. “When you think you are trying to multitask by doing two or more tasks at the same time, your brain is actually switching rapidly from one task to the other.” Multitasking reduces creativity, increases errors, lowers our ability to focus on what is most important, and increases problems with memory, sleep, and stress, she says. Instead, single-tasking is the way to go to be a high-performer. Here’s how to be more productive in your first hour of work.
