 If your hands and feet lock into this kind of claw position when you're really anxious or have a panic attack, this is why it happens and this is why it's not dangerous. When you're anxious and afraid, your breath is gonna change. Some people automatically start panting like a dog, others automatically hold their breath. Some people intentionally try to do deep breathing to calm down and in all cases, you can accidentally wind up hyperventilating. That means that the gases in your blood get all mixed up and three results of that would be numbness in your face, your hands and your toes and this thing, which is called carpopetal spasm and it's really alarming but it's not dangerous. Now you'll think that it's anxiety and panic doing something horrible to your body, but it's not. It's the way you're breathing when you're anxious or panicking that causes this. Even if you do accidentally hyperventilate when you're anxious, it can be really scary but it can't hurt you and it's something that could be addressed. Learning and practicing basic skills that help you slow down and even out your breath can help you avoid this common mistake. It's not gonna make things instantly better but it certainly will help not make them worse and that's something.
