There's a moment in crisis when words fail. When breathing techniques feel impossible because your chest is locked tight. When you can't remember a single coping skill because your mind is consumed by panic, rage, or overwhelming emotion. When your nervous system is so activated that rational thought has left the building entirely.

‍

‍

This is when you need something immediate, something physiological, something that works faster than thought.

This is when you need cold.

Temperature—specifically, cold temperature—is the "T" in TIPP, one of DBT's crisis survival skills. It's based on solid neuroscience: cold water on your face triggers an automatic physiological response that slows your heart rate, lowers blood pressure, and interrupts the body's stress response. It's called the "dive reflex," and it's hardwired into your nervous system.

You don't have to believe it will work. You don't have to feel motivated. You don't even have to want it to work. Put cold on your face, and your body responds automatically—like flipping a biological reset switch.

‍

‍

The Science: Why Cold Works

‍

The Mammalian Dive Reflex

Humans, like all mammals, have an evolutionary adaptation called the dive reflex. When your face comes into contact with cold water—especially the areas around your eyes, nose, and cheeks—your body automatically prepares for diving underwater by:

Slowing heart rate: Your heart rate can drop by 10-25% within seconds. This is called bradycardia, and it happens automatically, without conscious effort.

Redirecting blood flow: Blood vessels in your extremities constrict, redirecting blood to your vital organs—heart, lungs, and brain. This prioritizes the most critical systems for survival.

Lowering blood pressure: As your heart rate slows and blood flow is redirected, blood pressure decreases.

Activating the parasympathetic nervous system: This is your body's "rest and digest" system—the opposite of the "fight or flight" response. Cold water literally switches your nervous system from high alert to calming mode.

This isn't something you have to learn or practice to make it work. It's an involuntary physiological response, like your pupils dilating in dim light or your knee jerking when tapped with a reflex hammer.

‍

Why This Matters for Emotional Crisis

When you're in intense emotional distress—panic attacks, rage, overwhelming anxiety, despair—your sympathetic nervous system is in overdrive. Your heart is racing, you're breathing rapidly and shallowly, stress hormones are flooding your system, and the emotional centers of your brain are running the show while your rational prefrontal cortex is offline.

In this state, talking yourself down is difficult or impossible. Your thinking brain isn't available. You need something that bypasses cognition entirely and works directly on your physiology.

Cold does exactly that. It interrupts the cascade of physical symptoms that accompany and intensify emotional distress. When your heart rate slows and your nervous system shifts toward calm, the subjective experience of overwhelming emotion becomes more manageable.

You're essentially hacking your own biology—using an evolutionary survival mechanism to interrupt a crisis.

How to Use Temperature in Crisis

‍

The Basic Technique: Cold Water on Face

Fill a bowl with ice water. The colder, the better. Add ice cubes to make it genuinely cold—not just cool, but uncomfortably cold.

Hold your breath. This is important. The dive reflex is most effective when you're holding your breath, as it mimics the conditions of diving underwater.

Submerge your face. Bend over the bowl and put your face in the water, making sure the area around your eyes and nose is covered—these are the most sensitive areas for triggering the dive reflex.

Stay under for 30 seconds. If you can manage it, stay submerged for 30 seconds while holding your breath. If not, start with 15 seconds and build up.

Come up for air, then repeat if needed. Take a breath, then submerge again if the first round wasn't sufficient.

You should feel your heart rate slowing almost immediately. Some people notice the effect within 10-15 seconds.

‍

Alternative Methods When You Don't Have a Bowl

Ice pack or frozen gel pack on face: Hold a cold pack against your face, focusing on your forehead, eyes, cheeks, and the back of your neck. Hold your breath while doing this if possible. Keep it there for at least 30 seconds.

Bag of frozen vegetables: In a pinch, a bag of frozen peas wrapped in a thin towel works. Press it against your face, especially around your eyes and forehead.

Very cold, wet cloth: Soak a washcloth in the coldest water you can get, wring it out slightly, and drape it over your face. Not as effective as ice water, but still helpful.

Cold shower: Stand under cold or cool water, letting it run over your face and head. If you can't manage a full cold shower, at least splash very cold water on your face repeatedly.

Ice cubes held against face: Hold ice cubes wrapped in a thin cloth against your cheeks, forehead, or the back of your neck.

Stick your head in the freezer: Seriously. If you're home and in crisis and don't have ice water prepared, open your freezer and put your face in the cold air. It's not as effective as water, but the cold air can still help.

‍

Important Safety Considerations

Don't use cold if you have certain medical conditions. If you have heart problems, very low blood pressure, or conditions affected by sudden changes in heart rate or blood pressure, consult your doctor before using this technique. The dive reflex is powerful and can be too powerful for some medical conditions.

The water needs to be genuinely cold. For maximum effect, aim for 50°F (10°C) or colder. Room temperature or lukewarm water won't trigger the dive reflex effectively.

Don't stay under too long. While holding your breath and submerging your face, don't push past your comfortable breath-hold limit. Thirty seconds is usually sufficient; more isn't necessarily better.

Be careful if you wear contact lenses. Cold water can be uncomfortable for contact lens wearers. Consider removing them first if possible.

Have a towel ready. You'll be dripping wet. Having a towel nearby makes the experience less chaotic.

When to Use Temperature

‍

During Panic Attacks

Panic attacks involve intense physical symptoms—racing heart, rapid breathing, chest tightness, dizziness. These physical sensations then fuel more panic, creating a frightening feedback loop.

Cold water interrupts this loop by directly slowing your heart rate and shifting your nervous system. Many people report that using cold during a panic attack reduces the intensity significantly within a minute or two.

The physical change—feeling your heart rate actually slow—also provides cognitive reassurance: "This is working. I'm getting calmer. I'm going to be okay."

‍

When Rage Feels Uncontrollable

Intense anger involves high physiological arousal—your heart pounds, your face gets hot, your muscles tense, stress hormones surge. In this state, you're primed to act impulsively in ways you'll regret.

Cold gives you a circuit breaker. It's hard to stay in full rage mode when your face is submerged in ice water. The physiological calming creates space for your rational mind to come back online.

Use cold before sending that text, before saying something you can't take back, before slamming the door or throwing something. Give yourself 30 seconds of cold water, then reassess whether you still want to act on the impulse.

‍

During Overwhelming Anxiety or Dread

Sometimes anxiety isn't a discrete panic attack—it's a sustained state of dread, worry, and physical tension that won't let up. Your thoughts spiral, your body stays tight, nothing helps.

Cold can provide a reset. It won't solve whatever you're anxious about, but it can bring your arousal level down enough that you can think more clearly, use other coping skills, or at least get through the next hour.

‍

Before Deliberate Self-Harm

For people who struggle with urges to self-harm, temperature can serve as a safer alternative that still provides strong physical sensation and a sense of release.

Holding ice cubes, submerging hands in ice water, or putting an ice pack on the area where you'd typically harm creates intense sensation without causing damage. The cold is genuinely uncomfortable—it's not a pleasant distraction—which can satisfy the need for physical intensity that often accompanies self-harm urges.

Combined with riding out the urge (which typically peaks and subsides within 15-20 minutes), cold can help you get through the crisis without injury.

‍

When Other Skills Feel Impossible

Sometimes you're too activated to use skills that require thinking—you can't do a pros and cons list, you can't practice mindfulness, you can't implement DEAR MAN. Your brain is offline.

This is when you need something that doesn't require thinking. Cold is that something. Use it first to bring your arousal down, then reassess whether other skills are now accessible.

‍

Preparing Your Temperature Kit

Don't wait until you're in crisis to figure out how to use cold. Prepare ahead:

Keep gel ice packs in your freezer. Buy several—the flexible gel packs that conform to your face work well. Keep them frozen and ready.

Have a dedicated bowl. Keep a specific bowl designated for this purpose, so you don't have to search for one during a crisis.

Stock ice cube trays. Make sure you always have ice available. Consider making extra-large ice cubes or freezing water in small containers for longer-lasting cold.

Create a temperature station. In one accessible place, keep: ice packs, a bowl, a towel, and any other items you might use. When crisis hits, you don't want to be searching through drawers.

Keep cold packs in multiple locations. One in your freezer at home, one at work if possible, one in a cooler in your car during hot months. The more accessible cold is, the more likely you'll use it when needed.

Practice when not in crisis. Try the technique when you're calm so you know what to expect and how to do it effectively. This reduces barriers to using it when you actually need it.

‍

Combining Temperature With Other Skills

Temperature works well in combination with other crisis survival skills:

‍

Temperature + Paced Breathing

After using cold to slow your heart rate, practice paced breathing—long exhales, steady rhythm. The combination of physiologically reduced arousal plus regulated breathing is powerful.

‍

Temperature + Distraction

Use cold to interrupt the crisis, then engage in intense distraction—a video game, cleaning, exercise—to maintain the momentum away from emotional overwhelm.

‍

Temperature + Opposite Action

If your emotion wants you to isolate, use cold first to reduce the intensity, then do the opposite action of reaching out to someone.

‍

Temperature + Self-Soothing

After the acute crisis passes, transition from the intensity of cold to gentler self-soothing—a warm bath, soft blanket, comforting scents. The contrast can be soothing.

‍

‍

What Temperature Won't Do

‍

It's important to have realistic expectations:

Temperature won't solve the underlying problem. If you're panicking about an upcoming exam, cold water will reduce the panic but won't help you study or make the exam go away. It buys you time and creates space, but you still need to address the actual issue.

Temperature won't eliminate emotions. It reduces the intensity of physiological arousal, but it doesn't make emotions disappear. You might still feel anxious, angry, or sad—just less overwhelmingly so.

Temperature is a short-term intervention. The effects last for minutes, not hours. It's for getting through acute crisis moments, not for managing ongoing emotional difficulties.

Temperature won't work if you're not actually in high arousal. If you're feeling sad but not physiologically activated—no racing heart, no tension—cold water won't help much because there's no activated stress response to interrupt.

‍

‍

Common Obstacles and Solutions

‍

"It's too uncomfortable"

Yes, ice water on your face is intensely uncomfortable. That's part of why it works—the strong sensation demands your attention and interrupts the emotional cascade.

If it's truly intolerable, you're probably not in high enough crisis to need it. Save temperature for moments of genuine emergency when discomfort is preferable to the alternative (panic attack, self-harm, saying something destructive).

‍

"I don't have ice water available"

This is why preparation matters. But if you're caught without it: splash the coldest water available on your face repeatedly. Go outside if it's cold. Put your face in front of an air conditioner. Use whatever cold you can access.

‍

"It feels silly"

Crisis survival skills often feel silly when you're not in crisis. When you are in crisis and your heart is pounding at 140 beats per minute and you feel like you're dying, you won't care how silly it looks to stick your face in a bowl of ice water.

Also, you're probably doing this alone in your bathroom. No one's watching. Let it be silly if that helps you actually do it.

‍

"I forget to use it"

This is common. In crisis, your thinking brain shuts down and you revert to old patterns. Solutions:

• Practice when not in crisis so it becomes more automatic
• Put reminders in places you go during crisis (on your bathroom mirror, in your phone)
• Tell trusted people about the skill so they can remind you: "Have you tried ice water?"
• Keep your temperature kit highly visible so you see it and remember

‍

"My partner/roommate thinks it's weird"

Educate them about the dive reflex and the science behind it. Most people find it fascinating once they understand it.

If they remain unsupportive, you might need to establish a boundary: "I know it seems strange, but this is a tool that helps me manage intense emotions. I need you to respect that I use it, even if you don't fully understand it."

‍

‍

Beyond Crisis: Other Uses for Cold

While temperature is primarily a crisis skill, cold exposure has broader applications:

Increasing distress tolerance: Regular brief cold exposure (cold showers, cold plunges) can build your overall capacity to tolerate discomfort. You're literally training your nervous system to stay calm during unpleasant experiences.

Boosting energy and alertness: Morning cold showers can be invigorating and help with low energy or depression. The shock of cold activates your sympathetic nervous system in a controlled way.

Improving mood: There's emerging research on cold water immersion for depression. Regular cold exposure may increase dopamine and endorphins.

Building confidence: Successfully tolerating cold—doing something genuinely uncomfortable—builds self-efficacy. "If I can do this hard thing, I can do other hard things."

Some people incorporate brief cold exposure into their daily routine as a preventive practice, not just a crisis intervention. A 30-second cold shower each morning, for instance, can set a tone of resilience for the day.

‍

The Bigger Picture: Physiology-First Approaches

Temperature is part of a broader principle in DBT: sometimes you need to change your physiology before you can change your psychology.

When you're highly activated, trying to think your way out of distress usually doesn't work. Your prefrontal cortex—the thinking, reasoning part of your brain—is offline. The emotional and survival-oriented parts are running the show.

Physiological interventions like temperature bypass the thinking brain and work directly on your body. Once your body calms, your thinking brain comes back online, and then you can use cognitive skills, problem-solving, or emotional processing.

This is why TIPP exists as a set of crisis skills—Temperature, Intense exercise, Paced breathing, Paired muscle relaxation. All of them work on physiology first, creating the conditions for everything else to become possible.

‍

A Practice of Self-Compassion

Using temperature when you're in crisis is, at its core, an act of self-compassion. You're saying: "I'm struggling right now, and I deserve relief. I'm going to do something that helps, even though it's uncomfortable, because taking care of myself matters."

There's no shame in needing this tool. Needing temperature doesn't mean you're weak or broken—it means you're human, with a human nervous system that sometimes gets overwhelmed.

Every time you use cold water instead of acting destructively, every time you interrupt a crisis with this simple physiological intervention, you're practicing radical self-care. You're choosing yourself, your wellbeing, your future self who won't have to deal with the consequences of impulsive crisis behavior.

That choice matters. That choice changes things.
