Need Grounding Techniques for Teens | Forum

I'm looking for grounding techniques for teens. What do you guys suggest? My teenager has been feeling anxious and overwhelmed lately, and I want to help them find some effective ways to stay calm and focused. I've heard about methods like deep breathing, mindfulness, and physical activities on Choose Grounding website, but I'm curious if there are any other approaches that have worked well for your teens. Any specific apps, exercises, or routines that you recommend?
