Spa or classic music can help. Massage works wonders especially reflexology which is a foot massage because the nerves on the bottom of your feet corresponds to different organs and areas all over your body. So when you get a foot massage it helps you to relax all over your body. So as your body relaxes your mind relaxes as well.
Long walks also helps. It also helps to be around bodies of water so if you can go to the beach or near a lake. Water is very calming.
