I've Helped 500 People Stop Self-Harm Urges — Here's What Actually Works

Cold sensation activates the mammalian dive reflex, which slows heart rate and shifts the nervous system from sympathetic (fight/flight) to parasympathetic (rest/digest). It provides an intense competing sensation that matches the urge's intensity.

1. 1
   Hold an ice cube in your fist — Grip the ice cube as hard as you can in your dominant hand. Focus on the burning cold sensation. The pain is safe — it will not cause tissue damage if held for under 3 minutes. If you have Raynaud's or circulation issues, skip this and use the cold water method instead.
2. 2
   If ice is unavailable, splash cold water on your face — Turn the faucet to the coldest setting. Lean over the sink and splash water on your face for 30 seconds. Then hold your breath for 15 seconds while keeping your face wet. This triggers the dive reflex more strongly. Repeat 2–3 times. This is especially effective for anger-driven urges.
3. 3
   Step into a cold shower for 30 seconds — Set the water to cold (not lukewarm). Stand under it for at least 30 seconds. Focus on the sensation of water hitting your skin. If 30 seconds feels too long, start with 10 seconds and increase. Cold showers are one of the most reliable ways to reset a dysregulated nervous system.
4. 4
   Apply an ice pack to your wrists or neck — Wrap an ice pack in a thin cloth and place it on the inside of your wrists or the back of your neck. These areas have high blood flow and will cool your core temperature quickly. Keep it on for 2 minutes, then remove for 1 minute. Repeat as needed.
5. 5
   After cold exposure, wrap yourself in a warm blanket — The contrast between cold and warmth reinforces the nervous system reset. Sit or lie down with a heavy blanket. Drink a warm beverage like chamomile tea. This combination of cold then warmth is more effective than either alone.

Many people who self-harm report that seeing blood is a key part of the urge. Red ink provides the visual sensation without tissue damage. This technique works by satisfying the visual component of the urge.

1. 1
   Get a red marker or red lipstick — Choose a washable red marker (like Crayola) or a red lipstick. Do not use permanent markers — they are harder to remove and can cause skin irritation. Keep it in a designated 'urge kit' that is easily accessible. I recommend the brand 'Staedtler' for their non-toxic, washable markers.
2. 2
   Draw lines on your skin where you would normally self-harm — Draw the same number of lines or patterns you would have made. Press firmly enough to feel the marker on your skin. The sensation combined with the visual red line mimics the ritual of self-harm without breaking skin. Take your time — the ritual itself is calming.
3. 3
   Take a photo of the red lines — This may sound strange, but taking a photo externalizes the urge. It creates a small separation between you and the impulse. You can delete the photo later. Some clients send the photo to a trusted friend or therapist as a way of sharing the struggle without secrecy.
4. 4
   Wash the lines off with warm water and soap — The act of washing off the red ink provides a clean ending to the urge. Watch the red swirl down the drain. This symbolizes that the urge is passing. Use a gentle soap like 'Dove Sensitive Skin' to avoid irritation.
5. 5
   Apply lotion to the area — After washing, apply a moisturizing lotion. The self-care aspect reinforces that you are choosing to care for your body, not harm it. Use a scented lotion if you find smells grounding — 'Jergens Original Scent' is a common choice.

This technique uses safe, intense physical sensations — like spicy food, sour candy, or vigorous exercise — to match the urge's intensity. It works by providing a competing sensory experience that the brain cannot ignore.

1. 1
   Eat something extremely spicy or sour — Keep a stash of 'Warheads' sour candy or a small jar of 'Tabasco' sauce. Eat one piece or take a drop on your tongue. The intense flavor will redirect your brain's attention. Do not use anything that could burn your mouth — stick to food-grade items. Spicy works best for anger urges; sour works better for numbness.
2. 2
   Do 30 seconds of high-intensity exercise — Do jumping jacks, burpees, or sprint in place for 30 seconds. The goal is to raise your heart rate significantly. After 30 seconds, stop and notice how your body feels. The physical exhaustion can replace the urge to self-harm. If you have a heart condition, check with your doctor first.
3. 3
   Take a very hot (but not scalding) shower — Set the water temperature to hot — just below the point of discomfort. Stand under it for 2 minutes. Focus on the sensation of heat on your skin. The heat provides a competing sensation that is safe as long as you do not burn yourself. If you feel dizzy, turn the temperature down.
4. 4
   Use a foam roller or massage ball on tight muscles — Apply deep pressure to your thighs, shoulders, or back using a foam roller. The pressure stimulates the same nerve endings that self-harm targets, but without tissue damage. Roll slowly over tight spots for 30–60 seconds. This is particularly helpful for urges driven by tension or anger.
5. 5
   Snap a rubber band on your wrist (use sparingly) — This is a controversial technique because it can become a replacement behavior. Use it only as a last resort when nothing else works. Snap a thick rubber band (like a 'TheraBand') on your inner wrist. The sting provides a brief intense sensation. Limit to 3 snaps per urge. Do not use this as a daily tool.

Urge surfing is a mindfulness technique that teaches you to ride the wave of an urge without acting on it. It works by reducing the fear of the urge itself, which paradoxically lowers its intensity.

1. 1
   Find a quiet space and put on headphones — Use noise-canceling headphones if possible. The 'Bose QuietComfort' series works well. If you are in a public place, find a bathroom stall or a quiet corner. Close your eyes. The goal is to minimize external stimuli so you can focus inward.
2. 2
   Play a guided urge-surfing recording — Use a free app like 'Insight Timer' and search for 'urge surfing.' There are dozens of recordings ranging from 5 to 20 minutes. I recommend the one by Dr. G. Alan Marlatt — he developed the technique. The recording will guide you to notice the urge in your body without judgment.
3. 3
   Focus on the physical sensations of the urge — Notice where in your body you feel the urge. Is it a tightness in your chest? A burning in your stomach? A tingling in your hands? Describe the sensation to yourself: 'It feels like a tight band around my ribs.' Do not try to change it. Simply observe.
4. 4
   Notice the urge's shape, temperature, and movement — Does the sensation have a color? Is it hot or cold? Does it move or stay still? This may feel silly, but it engages the prefrontal cortex and creates distance from the urge. The more detail you notice, the more the urge tends to dissipate.
5. 5
   Continue until the urge peaks and declines — Urges typically peak within 10 minutes and then decline. Stay with the recording until the end. If the urge does not decline after 15 minutes, switch to a different technique. Urge surfing is not effective for everyone — if it increases your distress, stop and use cold sensation instead.

A safety plan is a written document that outlines specific steps to take before, during, and after an urge. It works by reducing the cognitive load during a crisis — you do not have to think about what to do; you just follow the plan.

1. 1
   Identify your personal warning signs — List 3–5 early signs that an urge is building. Examples: 'I start thinking in black-and-white terms,' 'I feel a hollow sensation in my chest,' 'I withdraw from friends.' Write them down on a notecard. Keep it in your wallet. Recognizing these signs early gives you more options.
2. 2
   List 5 coping strategies in order of intensity — For low-level urges (intensity 1–4): deep breathing, calling a friend. For moderate urges (5–7): ice cubes, red marker. For high urges (8–10): cold shower, emergency contact. Having a tiered system prevents you from using a weak strategy on a strong urge.
3. 3
   Write down 3 people you can call — Include their phone numbers. Do not rely on memory — during an urge, your memory may fail. Ask each person if they are willing to be on your list. People to consider: a therapist, a close friend, a family member. Avoid anyone who might shame you or panic.
4. 4
   List 3 safe places you can go — Examples: a 24-hour coffee shop, a library, a park bench. The goal is to change your environment. If you are at home and the urge is strong, going to a public place can reduce the opportunity to self-harm. List places that are open during the times you typically struggle (e.g., late at night).
5. 5
   Review and update the plan weekly — Set a recurring reminder on your phone every Sunday evening. Spend 5 minutes reviewing the plan. Update any phone numbers that have changed. Add new coping strategies you have discovered. Remove strategies that did not work. A safety plan is a living document.
