Cold towels and ice packs tend to be more effective for migraines, while warm towels often work better for tension-type headaches caused by tight muscles in the neck and shoulders. The distinction matters because the two most common headache types involve different mechanisms, and temperature therapy targets each one differently. A systematic review and meta-analysis of cold therapy for migraines found a meaningful short-term pain reduction within 30 minutes, and a randomized trial comparing heat and cold head-to-head for headache pain found that both outperformed doing nothing. The real answer, then, is less about which temperature is universally “better” and more about matching the towel to the headache.
Why Cold Works So Well for Migraines
If you get migraines, cold is usually your best starting point. The strongest evidence for temperature-based headache relief comes from studies of cold therapy applied during migraine attacks. A systematic review and meta-analysis of cold interventions for migraine found that cold treatments produced a large short-term reduction in pain scores at 30 minutes compared to non-cold approaches.1PubMed. Cold intervention for relieving migraine symptoms: A systematic review and meta-analysis The effect was substantial enough to be clinically meaningful, not just statistically detectable. However, the same analysis found that the longer-term benefit at 24 hours was only marginal, and the effect on nausea did not reach statistical significance. Cold therapy, in other words, tends to hit fast and fade.
A randomized controlled trial using a frozen neck wrap applied at the onset of migraine found roughly a 32% decrease in pain at the 30-minute mark in the treatment group, while the control group actually experienced about a 32% increase in pain over the same period.2PubMed Central. Randomized Controlled Trial: Targeted Neck Cooling in the Treatment of the Migraine Patient That is a striking divergence. The study also noted that once the frozen wrap was removed, the improvement started to slip, dropping to about a 27% pain reduction at the one-hour mark. The implication is clear: cold works, but you want to catch the migraine early and keep the cold in place for at least 20 to 30 minutes.
The mechanisms behind this are partly vascular and partly neurological. Blood flowing through the carotid arteries in the neck can be cooled enough to reduce the release of inflammatory substances from intracranial blood vessel walls, decrease vascular permeability, and dampen local pain signaling. There may also be a degree of cold-induced vasoconstriction in the area, which works through a different pathway than migraine medications but achieves a somewhat similar narrowing effect on dilated vessels.3PubMed Central. Randomized Controlled Trial: Targeted Neck Cooling in the Treatment of the Migraine Patient – Section: Discussion On top of that, the sensation of cold activates nerve fibers around the cranial vessels that contribute a small analgesic effect. So cold is not just numbing the area; it is actively working on inflammation, blood vessel diameter, and pain signaling at the same time.
When Heat Is the Better Choice
Tension-type headaches feel like a band squeezing around your head, and they are often driven by muscle tightness in the neck, shoulders, and scalp. For this kind of headache, heat tends to be more helpful than cold. A warm towel draped across the back of the neck and upper shoulders relaxes contracted muscles, improves blood flow to the area, and can ease the stiffness that is feeding the pain cycle. Heat therapy improves muscle flexibility and increases local blood flow and metabolism, which makes it well suited for conditions involving chronic muscle pain, stiffness, and strain.4PubMed Central. Heat Therapy for Musculoskeletal Pain Conditions: Actionable Suggestions for Pharmacists from a Panel of Experts – Section: 2.2. HT vs. Cold Therapy in MSK Disorders
Cold therapy, by contrast, reduces blood flow and muscle metabolism. While that is exactly what you want when inflammation is driving a migraine, it can actually tighten muscles further when the problem is already muscular tension. Applying an ice pack to already-knotted neck muscles sometimes makes things worse. If your headache comes on after hours at a desk, after sleeping at a bad angle, or when you feel your shoulders creeping up toward your ears, reach for the warm towel first.
Warm water exposure also appears to shift the body’s autonomic nervous system toward a more relaxed state, increasing vagal tone and decreasing sympathetic activity.5PubMed Central. Influence of hydrotherapy on clinical and cardiac autonomic function in migraine patients – Section: Discussion That parasympathetic shift is the biological version of your body switching from “fight or flight” into “rest and digest” mode. For headaches rooted in stress and muscular bracing, that systemic relaxation response can be as important as the local muscle-loosening effect.
The Head-to-Head Comparison
Surprisingly few studies have directly compared heat and cold therapy for the same type of headache. One randomized controlled trial did exactly that, enrolling 75 cardiac patients who developed headaches from nitrate medication (a common side effect). The patients were split into three groups: heat therapy, cold therapy, and a control group receiving neither. Both the heat and cold groups received their therapy for 25 minutes, applied twice with a one-hour interval between applications. Before treatment began, all three groups had similar pain levels. After the interventions, both the heat and cold groups showed significantly less headache pain than the control group.6AÄŸrı – The Journal of The Turkish Society of Algology. Comparing the Effect of Heat and Cold Therapy on the Intensity of Nitrate Induced Migraine Type Headache in Cardiac Inpatients: A Randomized Controlled Trial
The key takeaway from that trial is that both temperatures work better than doing nothing. The difference between heat and cold was less dramatic than the difference between either therapy and no therapy at all. For someone who finds cold uncomfortable or heat irritating, this is reassuring: the “wrong” temperature is still likely to help more than toughing it out with no treatment. That said, the headaches in this study were medication-induced and not typical spontaneous migraines or tension headaches, so the results do not map perfectly onto every situation.
Not Everyone Responds the Same Way
An open-label pilot study of cold therapy in migraine patients gives a useful reality check on individual variability. In the first application, half the patients reported a clinical benefit within 25 minutes. About 38% had an objectively measurable response, including roughly 12% who had a complete response with their pain essentially disappearing. But the other half did not respond meaningfully and needed to use pain medication.7PubMed Central. Cold Therapy in Migraine Patients: Open-label, Non-controlled, Pilot Study In the second application during a subsequent attack, the numbers shifted slightly: about 58% reported benefit, but 42% again did not respond. Average pain scores dropped from about 8 out of 10 before treatment to roughly 5.5 at 25 minutes, continuing to fall to about 3.4 by three hours.
What this means practically is that cold therapy is not a guaranteed fix even for the headache type it is best suited for. You might be in the half that gets solid relief, or you might be in the group that barely notices. The only way to know is to try it during an attack and pay attention to what happens. If cold does not help your migraines after a few honest attempts, that does not mean temperature therapy is useless for you; it might mean heat is worth trying, or that you need medication alongside the towel rather than instead of it.
Where You Put the Towel Matters
The placement of the hot or cold towel is at least as important as the temperature. For migraines, the strongest evidence involves applying cold to the neck, specifically targeting the carotid arteries on the sides of the neck. That is where the frozen neck wrap was positioned in the randomized trial that found the roughly 32% pain reduction.2PubMed Central. Randomized Controlled Trial: Targeted Neck Cooling in the Treatment of the Migraine Patient The reasoning is that cooling the blood flowing through those large arteries has downstream effects on the intracranial vessels where migraine pain originates. Putting the cold pack on your forehead feels soothing and is not wrong, but the evidence specifically supports the neck as the most effective location for migraines.
For tension-type headaches, placement follows the muscle tension. If the tightness is concentrated in the back of the neck and base of the skull, that is where the warm towel should go. If the pain wraps around the temples and forehead, a warm compress across the forehead and temples can help. Some people find relief from placing warmth on the upper trapezius muscles (the large muscles running from your neck to your shoulders), especially when they can feel those muscles are knotted. The goal is to get the heat to the muscles that are contributing to the pain, not just to wherever the headache hurts most.
Sinus headaches are a different case entirely. The pain is usually concentrated behind the cheeks, forehead, and around the eyes, and it is driven by congestion and inflammation in the sinus cavities. A warm, moist towel across the face can help by loosening mucus and promoting drainage. Cold is generally less helpful for sinus headaches because it can increase congestion. If your headache comes with a stuffy nose and pressure that worsens when you bend forward, warm is almost always the better call.
Timing and Duration
The migraine neck-cooling trial applied the frozen wrap at the onset of the migraine, and the peak benefit appeared at 30 minutes.2PubMed Central. Randomized Controlled Trial: Targeted Neck Cooling in the Treatment of the Migraine Patient That detail about timing at onset is worth emphasizing. Like triptan medications, cold therapy for migraines appears to work best when you catch the attack early. Waiting until the pain is fully established and then reaching for an ice pack is likely to be less effective than applying cold at the first sign of an aura or prodrome.
For both hot and cold applications, 15 to 25 minutes is a reasonable window. The comparative trial used 25-minute applications, and the pilot study measured outcomes at 25 minutes. Going much longer than 30 minutes with cold risks numbing the skin excessively or causing mild tissue irritation, and most gel packs and frozen towels lose their therapeutic temperature within that timeframe anyway. For heat, the same general window applies, though warm towels lose heat faster than cold packs lose cold, so you may need to rewet and reheat partway through.
The comparative trial also used a repeated-dose approach: two 25-minute applications separated by an hour.6AÄŸrı – The Journal of The Turkish Society of Algology. Comparing the Effect of Heat and Cold Therapy on the Intensity of Nitrate Induced Migraine Type Headache in Cardiac Inpatients: A Randomized Controlled Trial That suggests reapplying after a break can continue to reduce pain beyond what a single application achieves. If your headache is persistent, a cycle of apply, rest, reapply is a reasonable strategy for either temperature.
Migraine Without Aura Versus With Aura
An interesting detail from the neck-cooling trial is that patients without aura reported a much larger pain reduction at 30 minutes (about 39%) compared to those with aura (about 11%).2PubMed Central. Randomized Controlled Trial: Targeted Neck Cooling in the Treatment of the Migraine Patient The aura group also had a much wider spread in their results, meaning some individuals with aura did very well and others barely responded. This is only one study, and the sample sizes within each subgroup were small, so this should not be taken as definitive. But if you get migraines with aura and cold therapy has never seemed to work well for you, this finding at least suggests a possible explanation. The underlying mechanisms driving aura-associated migraines may be less responsive to the vascular effects of cooling.
Alternating Between Hot and Cold
Some headache sufferers swear by alternating hot and cold applications, and there is a long tradition of contrast hydrotherapy in various therapeutic traditions. The concept behind Scottish showers, for example, involves alternating between warm and cool water exposure, which is thought to tone the capillaries and improve vascular responsiveness. One approach that has been explored combines warm water immersion at around 37°C for 15 minutes to promote vasodilation and muscle relaxation, followed by techniques that address venous drainage.8Balneo Research Journal. The use of combined techniques: Scottish showers, hot bath and manual techniques in the treatment of migraine headache
The evidence for contrast therapy specifically for headaches is thin compared to the evidence for cold alone. But the logic is not unreasonable: warm to relax tense muscles and open blood vessels, then cold to reduce inflammation and narrow vessels that have dilated too much. If you have a headache that seems to involve both muscle tension in the neck and migraine-like throbbing, alternating a warm towel for a few minutes followed by a cold one might address both components. Just be aware that this is more in the realm of plausible self-care than rigorously tested protocol.
Practical Tips for Getting the Most Out of Temperature Therapy
A few practical details can make the difference between temperature therapy that helps and temperature therapy that feels like a hassle for no payoff:
- Barrier layer: Never put ice or a frozen pack directly on skin. A thin towel or cloth between the cold source and your skin prevents frostbite-like irritation. This is especially important on the neck, where the skin is thinner.
- Moist heat: For warm applications, a damp towel heated in the microwave for 30 to 60 seconds often works better than a dry heating pad. Moist heat penetrates tissue more effectively and is particularly good for sinus headaches.
- Body position: Lying down in a quiet, dim room while applying the towel lets the temperature therapy work alongside sensory reduction. Bright light and loud noise can worsen migraines regardless of what you put on your head.
- Early application: Based on the migraine evidence, apply cold as soon as you feel the attack starting. Waiting until the headache is at its worst means the inflammatory cascade is further along and harder to interrupt.
When to Skip the Towel and See a Doctor
Temperature therapy is a reasonable first-line self-care strategy for the kinds of headaches most people get occasionally. But certain headache patterns warrant medical attention rather than a towel. A sudden, severe headache that reaches maximum intensity within seconds (sometimes called a thunderclap headache) can signal a medical emergency. Headaches that are progressively worsening over days or weeks, headaches accompanied by fever and a stiff neck, or headaches that follow a head injury all need professional evaluation. A new headache pattern after age 50 is also worth discussing with a doctor, since the causes of headaches shift as people age.
For people with chronic migraines (15 or more headache days per month), temperature therapy can be a useful add-on to a broader treatment plan, but it is unlikely to be sufficient on its own. Preventive medications, lifestyle modifications, and in some cases newer treatments like CGRP inhibitors may be needed to reduce the overall headache burden. The towel is a tool, not a complete solution, and the evidence supports using it alongside other approaches rather than instead of them.
Cluster Headaches and Other Less Common Types
Cluster headaches are a distinct category that affects a much smaller group of people but causes some of the most severe pain in medicine. They typically involve intense, stabbing pain on one side of the head, often around or behind one eye, and come in “clusters” of frequent attacks over weeks or months. The temperature therapy research has focused overwhelmingly on migraines and tension-type headaches, and there is very little evidence to guide cold or heat therapy specifically for cluster headaches. Some cluster headache sufferers report that cold applied to the temple on the affected side provides modest relief during an attack, but oxygen therapy and specific medications (like sumatriptan injections) are the primary evidence-based treatments. If you experience cluster headaches, temperature therapy is unlikely to be adequate, and a neurologist should be involved in your care.
Cervicogenic headaches, which originate from problems in the cervical spine and radiate into the head, often respond well to heat applied to the neck because the root cause is typically musculoskeletal. These headaches can mimic migraines, which makes them tricky to self-diagnose. One clue is that cervicogenic headaches tend to be triggered or worsened by specific neck movements or sustained postures. If you notice that your headache consistently starts in the back of the neck and spreads forward, or that turning your head in a certain direction makes it worse, a warm towel on the neck muscles is a reasonable starting point while you pursue a proper evaluation.
