How Your Body's Space Changes When You're Stuck

We all have a personal bubble around us. It's like an invisible shield that helps us sense things near our body. But what if you can't move? Does this bubble change? Scientists wanted to find out. They did two experiments. In the first one, they put people in a big box and asked them to react to touches on their chest while watching something move closer. The second experiment was similar, but they used different box sizes. The results were interesting. When people were in the box, their personal bubble seemed to shrink. The smaller the box, the more their bubble changed. But the exact size of the bubble was hard to measure. However, people felt more stuck in the smaller box. This tells us that being unable to move can make us more aware of things near our body. It's like our senses get sharper when we're stuck. But why does this happen? Maybe our brain tries to protect us when we can't move. Or maybe it's just trying to understand our new situation. Either way, it's a cool example of how our body and brain work together.
