In order to relax, relieve tension, relax for 15-20 minutes, it is very good to practice Shavasana or Nidra Yoga. You can turn on a ready-made recording of Shavasana or Nidra, close your eyes and try to relax while listening to the voice of the presenter.The tension in the body goes away, the mind calms down, after the session there is cheerfulness in the body, the mind becomes clear as after a dream. I recommend it!
