Effective grounding techniques include the 5-4-3-2-1 method, which involves naming five things you can see, four things you can touch, three things you can hear, two things you can smell, and one thing you can taste. Another technique is to focus on physical sensations, such as pressing your feet firmly into the ground or holding a piece of ice in your hand. These techniques help shift your focus away from the panic attack and bring your attention to the present moment.
