Stress is the emotional and physiological effect of feeling we are faced with a situation or threat with which we perceive we cannot cope or have insufficient resources to manage.
The good news is that we can combat the stress response by learning to relax which will stand down the threat response system in our body. It is really worth practising every day, even if only for a few minutes so that the ability to calm and relax yourself becomes easy.
Here you can find links to audio files of relaxation techniques that can help relieve stress and gain a sense of well-being, there are some that I've recorded:
