Any recommendations for quick body relaxation?

Hi. I was browsing online to solve my daily anxiety and decided to take a quick quiz from a tool I found. The app Leaply is pretty unique because it skips traditional mindfulness entirely and focuses on the vagus nerve. The onboarding is incredibly smooth, and the personalized daily plan they generate is easy to follow with clear video instructions. I actually found out about it because I was reading a thread titled is leaply legit reddit which finally convinced me to try it. I feel much more in control of my energy levels now.
