Richard Stevenson, Lauren, Macquarie University discussed on BrainStuff



Instead of an odd today, I have a message from the council. Nobody likes an awkward silence, but sometimes it can be a good thing. Use an awkward silence to ask your friend about their mental health. It can really help find out how at sees the awkward dot org. Welcome to brain stuff from how stuff works. Hey, brain stuff, Lauren, vocal bomb here. If you're anything like me and you were to keep track of some of your thoughts during a given day, gosh, I'm hungry would appear on the list a few times along with perhaps, why am I keeping track of my thoughts? But why do we often feel hungry? Let's be clear. We're not talking about actual starvation or hunger as a pervasive global and social issue, which it is and is a whole other episode or seven. We're talking about hunger in typically healthy people with comfortable access to food. The hunger that arises from the physiological need for nutrients to survive hormones and be nervous system regulate hunger and eating habits. But how the heck do we recognize when we want to eat, even when we actually don't need food? We spoke by Email with Richard Stevenson, a professor of psychology at MacQuarie university in Sydney, Australia, where he studies human eating behavior. He says that hunger is by no means a universally identifiable sensation. He wrote unlike fullness, which there is no, mistaking hunger is very varied. It is not a consistent sensation across people, and it has been claimed that feeling stressed can be confused with it. Even some of the biological functions that people associate with hunger. A growling stomach, for instance, aren't entirely foolproof. Cues. Stevenson said many people do not report stomach sensations. When asked to describe what being hungry is like, indeed, reports show that people site headaches, weakness, mouth-watering, and other non stomach related sensations as signs of hunger. Stevenson has also done research that indicates feelings of hunger and fullness are influenced by myriad of factors, including genetic and psychological differences like depression, anxiety, and eating disorders. Then there's a really big factor. Our environment could easily convince us into thinking it's time to eat. Whether we're hungry or not. Stevenson said that seeing smelling or even thinking about food will trickle into believing that our stomach is crying out for nutrients. He pointed out that this is why advertisements for food products work so well, and that affects not just appetite, but how much food we actually consume a two thousand nine study showed that both children and adults eat more snacks after exposure to food advertising. Any 2016 review found that food adds significantly increased unhealthy food intake in children. In fact, researchers coined the term had Dansk hunger to describe the drive for food consumption unrelated to the need for calories. This phenomenon might also give us a clue to a other mystery of hunger. How can we claim ourselves ravenous only to find after time passes or a distraction, interrupts whatever triggered the hunger paying that hunger has passed. A spy. Stevenson says, this waning hunger could be related to the. Idea that are appetite isn't always activated by an actual need for calories. And that quote time is a potent cue to eat. If you usually eat at midday and you miss this, you will feel hungry if you notice the time. So what's the trick to deciding whether you're truly hungry? Is there a scientific method for being able to push away that bowl of chips that you don't need Stevenson said in a word? No. Most of our biological machinery is geared to make us eat. When we see food or things that remind us of food, which was terrific for our ancient ancestors when humans had to spend a lot of time searching for energy sources, but it might lead us at a disadvantage when surrounded by a huge spread of snacks right after a filling meal. Today's episode was written by Kate Kirschner and produced by Tyler clang for more on this and lots of other filling topics, visit our home planet, how stuff works dot com. This is a time of great opportunity for us from modern medicine. Advancements are being made every day. For more than seventy five years. The central state hospital at new Canaan has provided treatment for those with mental disabilities? But in recent weeks, something has changed. One of our doctors has adopted methods of treatment that are more experimental in nature methods. One might consider ethically questionable.

To be honest, I don't understand what you're doing.
