Breathing and relaxation exercises for stress
"There are a lot of breathing and relaxation exercises you can do to relieve stress and relax your body and mind. The ones in this guide (from NHS Inform) are simple and can be done at home, at work or out and about. For some of them it helps to lie down, or sit, but they will still work if you aren't able to do those things Over time, these exercises can become something you do automatically, whenever you feel tense or stressed. This can help you become more relaxed in general."
