What happens in the body when stress settles in, the TCM perspective (the Liver and Qi stagnation), and what acupuncture can offer.

Stress is a normal and useful reaction: it prepares us to cope. The problem arises when it lasts and the body can no longer “let go”. A tight neck and jaw, a knotted stomach, palpitations, irritability, racing thoughts, disturbed sleep: these are all signs the body expresses.
Faced with a threat or pressure, the sympathetic nervous system activates and releases adrenaline and cortisol: the heart speeds up, muscles tense, digestion slows. This is effective in the short term. When this activation continues for too long, it becomes exhausting and contributes to fatigue, pain, digestive problems and sleep disturbances.
For TCM, the Liver ensures the free flow of Qi throughout the body. Under the effect of stress, this flow becomes blocked: this is Liver Qi stagnation. It is recognised by frequent sighing, a tight feeling in the chest, a “lump” in the throat, irritability, tension in the shoulders, unpredictable digestion, and, in women, painful periods.
Other organs are also affected: the Heart, seat of the Shen (the spirit), in cases of palpitations, restlessness and insomnia; the Spleen, with worry and rumination that exhaust and disturb digestion; the Kidney, when fear and exhaustion set in.
Many people describe a state of deep relaxation, during and after the session. Studies on anxiety and stress are encouraging but of variable quality: they suggest a benefit, without allowing its exact size to be determined.
Acupuncture is therefore a form of support. It does not replace psychotherapy, nor medication, when these are needed.
I use very small, single-use needles, much finer than a needle used for a blood test. Most of the time, you feel a light pinprick, then nothing more. Sometimes you feel nothing at all; some areas are more sensitive than others. This slight discomfort lasts a few seconds, then settles.
You may also feel, around the needle, a dull sensation of heaviness, warmth or tingling: this is expected and not a cause for concern. If anything bothers you, tell me: I can adjust or remove the needle straight away. Many people find the session very relaxing. If you are apprehensive about needles, tell me: we go at your pace, for example by starting with very few needles.
When should you see a doctor?
