@rosemarya I can only speak for myself. Crochet relaxes me a lot. I do charity work, making baby blankets, lap robes, shawls, and hats. As a beginner, all of my patterns are fairly simple and quick, which is good because I get easily distracted or bored. Each week I join with a group of ladies for a couple of hours to crochet for Prayer Shawl Ministry; I admit that a couple of times I have nodded off! As long as I don't snore I guess it's okay. I also try to crochet for about an hour each night before bed time to relax me. Besides, if I have yarn and hook in hand I can't reach for food! But yes, my blood pressure goes down a great deal when crocheting, or doing creative work.
