How Does Hunger Affect What You Buy?
I think everybody knows that it's a bad idea to go grocery shopping when you're hungry because you're going to spend more money and buy more junk. But there's more to the story. Hi and welcome to this episode of Something You Should Know. Not only does research support the fact that grocery shopping when you're hungry will cause you to spend more money, you probably have personal experience in that regard. But it turns out that shopping for anything on an empty stomach is a bad idea. Researchers at the University of Minnesota found that hungry people spent 64% more money at the mall on anything than shoppers who were not hungry. Apparently, hunger kicks in that human desire to hunt and gather. And since few of us are hunting and gathering in the traditional sense, we go shopping instead. Also, be aware of the scent of cinnamon. It seems that that makes you want to spend more money. And if you're a woman, a University of Texas study found that women want to buy more stuff when they're ovulating.
So that's another time to avoid going shopping. And that is something you should know. A very big concern today is screen time. How much time you or your kids have a computer or a tablet or a phone screen in front of your face. And the assumption is that you're probably spending too much time looking at screens. And what you really need to do is cut back and spend less time with screens. But what is too much time? What's the actual harm? Does screen time affect everyone the same way? What does the research say about how screen time impacts people? The answers to those questions just may surprise you. And here to reveal all this is Jacqueline Nisi. She is a psychologist and assistant professor at Brown University, and she writes a popular weekly newsletter called TechnoSapiens, which provides tips to manage your screen time. Jackie has published over 50 peer-reviewed publications related to technology use. She's testified before U.S. congressional and state legislative committees on issues surrounding technology and mental health.
