Alcohol doesn’t actually kill brain cells
279photo 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 performance
Rawpixel.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.
The brain can get distracted
Photographee.eu/Shutterstock The brain isn’t always inefficient when doing two things at once—but when it comes to higher-order thinking, distraction can severely impact the brain’s ability to stay on task. “The main limit arises when both of the tasks require attention—for example, we can carry out a conversation while walking, but if you were walking over a complicated, uneven, and dangerous path, it would be difficult to carry out an involved conversation at the same time,” says psychology professor Steven J. Luck, PhD, director of the Center for Mind & Brain at the University of California, Davis. This is the main reason distracted driving, such as while chatting on a cell phone, is so dangerous. We can’t see the other person on the phone, we might have trouble hearing them, and our brain has to imagine their environment. Driving is often automatic, so “we can do a pretty good job of talking on a cell phone and driving much of the time, but we have problems when the driving suddenly requires attention, for example, when something unusual happens, such as another driver coming to a sudden stop,” Dr. Luck says.
