A colleague once reached across a meeting table, took my hand without asking, and squeezed the fleshy bit between my thumb and index finger hard enough that I made a noise. I had been sitting there with my fingers pressed into my eye socket, which is apparently my tell for a 3pm desk headache.

"Two minutes," she said. "Press it yourself, that side and the other one."

I was entirely ready for this to be nonsense. It took the edge off in about three minutes: not gone, but down from "I need to leave" to "I can finish this meeting." It doesn't work every time; I'd say it helps me maybe half the time, which is a sentence you won't often read in an article about a wellness trick, and it's why I trust it more than the ones promising to cure everything.

What the point is and what's actually known

The spot is called LI4, or Hegu, and it's probably the most-used point in acupressure. It sits in the web of muscle between the thumb and index finger, and it's been used for headache and facial pain for a very long time.

On the evidence, I'd rather be straight with you than sell it: research on acupressure and acupuncture for tension headache and migraine exists and some of it is encouraging, but the studies tend to be small, hard to blind properly, and mixed in quality. It isn't nonsense, and it also isn't settled.

There are plausible mechanisms for why a firm press somewhere else might dull pain. Strong pressure sends competing signals up the same pathways, which is the same reason you instinctively rub a banged elbow. Firm pressure can prompt the body's own pain-damping chemistry. And two minutes of slow breathing while you focus on your hand is two minutes you aren't clenching your jaw at a screen.

It's free, it takes two minutes, and the main risk is a sore hand. That's a good deal even at uncertain odds: with one exception, which is in the next step.

Step 1: Find the point properly

Press your thumb and index finger together and look for the mound of muscle that bulges up between them: the highest point of that mound is where you're aiming. Then relax your hand before you press. Most people go too close to the finger web and miss the muscle entirely. One important caution: this point is traditionally avoided during pregnancy, so if you're pregnant, skip it and ask your midwife or doctor about safe options instead.

Step 2: Press firmly, angled toward the index finger bone

Use the thumb of your other hand to press into the mound, angling slightly toward the bone of the index finger, with your finger underneath as a backstop. The pressure should be firm enough to feel distinctly achy, a "good sore", but never sharp or burning. That dull ache is how you know you've found it rather than pressing on soft tissue nearby. Small circles or steady pressure both work.

Step 3: Hold for 30 to 60 seconds, then swap hands

Hold for up to a minute while breathing out slowly, then do the other hand, and repeat both after a few minutes if it's helping. Long exhales while you press are doing some of the work here. Don't go beyond a couple of rounds: the point of this is relief, and grinding your thumb into your hand for ten minutes just gives you a bruise and something new to be annoyed about.

My Expert Tip: If you're taking painkillers for headaches more than about ten days a month, the painkillers may be part of the problem. Medication-overuse headache is a recognized condition where frequent use of pain relief, including ordinary over-the-counter tablets, and especially combination or codeine-containing ones, sets up a cycle of rebound headaches that feel exactly like the headaches you were treating. It's easy to walk into, because every individual tablet works, and nobody counts. So count: mark the days on a calendar for a month. If you're over ten, that's a conversation with a doctor rather than a reason to try harder, and it's one of the most fixable things in this whole area. Never stop prescribed medicine on your own, though: the coming-off part needs proper guidance.

Step 4: Deal with the boring causes at the same time

Drink a glass of water, eat something if you've skipped a meal, get away from the screen for ten minutes, and roll your shoulders and neck. An enormous share of ordinary afternoon headaches come down to dehydration, a missed lunch, a delayed coffee, or two hours of holding your head forward at a monitor. None of that is exciting, and it resolves more headaches than any technique on this page. Do it alongside the pressure rather than instead of it.

Step 5: Keep a two-week trigger log

Note the time each headache starts, what you'd eaten and drunk, how you slept, and what you'd been doing for the previous two hours. Patterns show up quickly and they're almost never what you expected: mine were clustered on days I'd had my first coffee after eleven, which turned out to be plain caffeine withdrawal. A log is also the single most useful thing you can hand a doctor if you end up needing one.

Step 6: Know the headaches that need a doctor, not a thumb

Some headaches are not for self-treatment, and it's worth knowing which. Get urgent medical help for a headache that comes on suddenly and severely, like a thunderclap, or one that comes with fever and a stiff neck, confusion, weakness, numbness, slurred speech, or vision loss, or one that follows a head injury. Also see a doctor, not urgently, but properly, for a headache pattern that's new over the age of 50, one that keeps getting worse, one that wakes you from sleep, or any headache that's changed character from what's normal for you. Acupressure is for the ordinary ones.

Where this sits for me

Two minutes, no cost, works about half the time. On a good day it takes a 6/10 headache down to a 3 and I get on with the afternoon; on a bad day it does nothing at all and I go for a walk and drink some water instead.

The bigger change was the counting. I'd been taking something for a headache maybe three times a week without ever adding it up, and once I put dots on a calendar the number was uncomfortable. Having something free to reach for first, even something that works half the time, broke the reflex of going straight to the packet.

That's the honest pitch: not a cure, a first move. And a good reason to find out what your actual pattern is, which nobody discovers without writing it down.
