“Stress and anxiety can affect your memory and concentration. Relaxation techniques can help to reduce stress and anxiety, including listening to calming music, practising deep breathing, listening to a relaxation CD or using an app.
Some people find using mindfulness helpful. Mindfulness is about focusing on the present moment to try to reduce stress and improve your quality of life. Many people also practise mindfulness on their own – there are lots of books and websites dedicated to mindfulness, as well as apps.” – source: breastcancercare.org.uk
