Acupressure: the most important points and their effects

Summary (TL;DR)

Acupressure uses sustained finger pressure on defined points along the meridians. These are the same points as in acupuncture, just without needles. The technique is the same everywhere: perpendicular pressure with the thumb or index finger, 30 seconds to 2 minutes, in small circles or held, until a dull feeling of pressure develops. No sharp pain. The best-known points are LI4 (Large Intestine 4, between thumb and index finger), PC6 (Pericardium 6, three finger widths above the wrist), Yintang (between the eyebrows) and KD1 (Kidney 1, on the sole of the foot). PC6 for nausea is the most robustly studied. For most other uses, the evidence is thin. Do not press on injured or inflamed skin, over varicose veins or when you have a fever, and certain points are considered best avoided during pregnancy.

What acupressure is

Traditional Chinese medicine is based on channels, the meridians, along which the life energy Qi flows. Several hundred defined points lie along these channels. Acupuncture stimulates them with needles, acupressure with finger pressure.

For context, which this article does not leave out: meridians and Qi are a traditional explanatory model, not an anatomical finding. They cannot be imaged or measured. What can be observed is the effect of the pressure itself: increased local blood flow, lower muscle tone, stimulation of skin receptors and a clear relaxation response. These effects occur regardless of which model you follow.

One point that makes acupressure easier to understand: many of the classic points lie where there is also something anatomically, at muscle attachments, in gaps between tendons, at points where nerves emerge. The point between thumb and index finger, for example, sits in the middle of the first interosseous muscle, an area that is regularly tense in people who use a mouse or phone a lot.

Acupressure, trigger points and reflex zones

Three terms that are often confused:

• Acupressure points: traditionally defined points on meridians, in the same location in every person.
• Trigger points: palpable knots in tense muscles that cause radiating pain when pressed. Individual, with no fixed location, from Western manual therapy.
• Reflex zones: areas on the foot or hand that are traditionally assigned to organs. Areas, not points.

In practice, they often overlap: what someone presses as an "acupressure point on the neck" is often a trigger point in the trapezius muscle.

The technique: the same everywhere

1. Find the point. Feel around the described spot. The right point usually feels slightly more sensitive or firmer than the tissue next to it. That is the most reliable guide, more reliable than any drawing.
2. Press perpendicularly. With the pad of your thumb or index finger, not with the nail. The pressure goes inwards, not at an angle.
3. Increase slowly until a clear, dull feeling of pressure develops. That is the aim, not sharp or stabbing pain.
4. Hold or circle. Either hold steadily for 30 seconds to 2 minutes or move in small circles. Both work.
5. Breathe calmly. Deeply and slowly. A good part of the effect comes from this.
6. Release slowly, do not let go abruptly.
7. Both sides. Points on the arms and legs exist twice. Treat both.

Two to three times a day per point is fine. If a spot stays tender afterwards, it was too much.

The best-known points

Short routines for everyday life

• Tension headache: LI4 on both sides for 1 minute each, then GB20 on both sides for 1 minute, finally Yintang for 1 minute.
• Tense neck at the desk: GB20 on both sides, then SI3, turning your head slowly to both sides in between.
• Unable to switch off in the evening: Yintang, then KD1 on both feet, 2 minutes each, breathing calmly.
• Nausea when travelling: PC6 on both sides, 2 to 3 minutes, repeat if needed.

What the evidence shows, and what it does not

Precision pays off here, because a lot is claimed about acupressure.

Comparatively well studied: stimulating PC6 for nausea and vomiting, for example with travel sickness or after operations. For this use there are a number of controlled studies with positive results, which is why acupressure bands are also sold in pharmacies.

Mixed: tension headache, period pain, sleep quality, anxiety before procedures. There are studies with positive effects, but many are small, methodologically weak or hard to blind. With a technique in which both sides know what is happening, the placebo share can hardly be calculated out.

Not supported by evidence: influencing internal organs via meridians, treating diseases, detoxification, strengthening the immune system. Anyone who promises this goes beyond what the data shows.

That does not make acupressure worthless. It makes it what it is: a free, low-risk self-help technique with a noticeable relaxing effect and good evidence for one specific area of use. Not a substitute for therapy.

When you should not press

• Injured, inflamed or irritated skin, open wounds, fresh scars, sunburn
• Over varicose veins and visible dilated veins
• With a fever or acute infections
• Directly on bones, joints or the spine
• On the front and sides of the neck. The carotid artery and sensitive nerve structures run there
• With thrombosis or suspected thrombosis
• When taking blood-thinning medication: much more gently, because bruises form more easily
• With cancer: consult your doctor

Pregnancy

A separate point that should be taken seriously: according to traditional teaching, several points are avoided during pregnancy, including LI4 (the most widely used point of all), SP6 on the inner ankle and points in the area of the sacrum and abdomen. Whether there is an actual effect behind this is unclear. Caution is still the right approach. Discuss acupressure during pregnancy with your midwife or doctor first.

Where acupressure fits

As quick self-help, it is hard to beat: instantly available, free, no risk when used properly. Two minutes at the desk when your neck tightens up is more realistic than a massage appointment.

For stubborn tension it is too localised. That needs work over a wider area. Which form of massage suits what is covered in Types of massage at a glance. The related but much more intensive form of treatment is Tuina, which works with the same points but also kneads, rolls and stretches.

For daily use without using your own thumbs, devices are an option. What they can do is covered in Which massager for neck tension and How useful is a massager?. And if headaches occur frequently or are new, the cause should be investigated, not pressed away. See Can massages trigger migraines?.

Conclusion

Acupressure is the lowest-risk technique in this field and the only one you can use straight away with nothing at all. The technique can be learned in one sentence: press perpendicularly until you feel a dull pressure, hold for one to two minutes, breathe calmly.

Expect relaxation and relief from tension-related complaints. It reliably delivers that. Do not expect any effect on organs or a substitute for therapy. And if you are pregnant, clarify beforehand which points to leave out.

Frequently asked questions (FAQs)

How do you press acupressure points correctly?

Press perpendicularly inwards with the pad of your thumb or index finger, never with the nail. Increase the pressure slowly until a clear, dull feeling develops, not sharp pain. Then hold for 30 seconds to 2 minutes or move in small circles, breathing calmly, and then release slowly. Treat points on the arms and legs on both sides.

Which acupressure point helps with headaches?

Traditionally, LI4 between thumb and index finger is used, supplemented by GB20 in the hollows at the lower edge of the back of the head and Yintang between the eyebrows. About one minute per point. LI4 is avoided during pregnancy. With new, very severe headaches or headaches accompanied by visual or speech disturbances, see a doctor rather than using acupressure.

How often can you use acupressure?

Two to three times a day per point is fine, for one to two minutes each time. If a spot stays tender afterwards or a bruise forms, the pressure was too strong. Take a break for a few days.

Does acupressure really work?

There is a robust body of studies on stimulating PC6 for nausea. For tension headache, sleep problems and period pain, the results are mixed. The studies are mostly small and hard to blind. There is no evidence that it influences internal organs via meridians. The noticeable relaxing effect of pressure and breathing occurs regardless.

What is the difference between acupressure and acupuncture?

Both work with the same points. Acupuncture uses needles and belongs in expert hands. Acupressure uses finger pressure and you can apply it yourself. Acupressure is a weaker stimulus, but it carries no risk of injury and is available at any time.

Which acupressure points should be avoided during pregnancy?

According to traditional teaching, the points avoided include LI4 between thumb and index finger, SP6 above the inner ankle and points in the area of the sacrum and abdomen. Whether there is a real effect behind this is unclear, but restraint is still sensible. Discuss acupressure during pregnancy with your midwife or doctor first.
