Hi Angie and Lynn, mindfulness was suggested in the 2 day long covid educational class that I attended in Jacksonville FL. They encouraged 20 minutes twice a day (brefore breakfast and supper). There were no instructions given, but there are many helpful online guides. I personally use relaxing sounds on my fitbit app and lie down in a quiet room for 20 minutes with no interruptions. Over time I have found that just listening to the sound track is enough to drop my heart rate within 5 minutes.
