 Closing your eyes or popping on a pair of sunglasses can help reduce the overwhelm of visual input. Ear protectors or headphones can help dampen out background noise. We're a really big fan of loops which are a bit more discreet. Gentle music or white noise can help to calm things down quite quickly. Sometimes we need to find a small space. This is called containment. Putting our hood up or finding a little nook where we can go and hide often does the trick. Engaging with our stims or special interest tends to feel good and can help to calm us down. Focus in on the feel and the sound of your breath for a few moments. Take control.
