A tension headache is the most common type of headache, producing a steady, pressing pain on both sides of the head that many people describe as a tight band squeezing their forehead and temples. More than 70% of some populations experience episodic tension headaches, and they affect women about 50% more often than men. Unlike migraines, tension headaches are usually mild to moderate and don’t stop you from going about your day.
What a Tension Headache Feels Like
The hallmark sensation is constant pressure, like someone is squeezing the sides of your head together. The pain is dull and steady rather than throbbing or pulsing, and it typically shows up on both sides of the head at once. It often starts in the neck and shoulders before creeping up to the forehead. Intensity ranges from mild to moderate, meaning it’s uncomfortable but rarely debilitating.
A single episode can last anywhere from 30 minutes to seven days. You won’t usually experience nausea, vomiting, or changes in vision. You might notice mild sensitivity to light or sound, but not both at the same time, and it won’t be as intense as what migraine sufferers describe. Crucially, routine physical activity like walking or climbing stairs doesn’t make the pain worse.
Episodic vs. Chronic Tension Headaches
Tension headaches fall into three categories based on how often they occur. Infrequent episodic tension headaches happen fewer than 12 days per year. Frequent episodic tension headaches strike between 1 and 14 days per month for at least three months. Chronic tension headaches occur 15 or more days per month for three months or longer, sometimes lasting hours to days or feeling nearly constant.
The distinction matters because frequent and chronic forms can significantly affect quality of life and often require a different treatment approach than the occasional headache you can shrug off with a pain reliever.
Common Triggers
Stress is the most recognized trigger. When you’re stressed, muscles in your shoulders and neck tighten, and that tension radiates upward. When these headaches become frequent, the brain begins interpreting ongoing muscle tension in the neck and shoulders as head pain, even when the original source of tightness is below the skull.
Poor sleep is another reliable trigger. The exact mechanism isn’t fully understood, but the correlation is strong enough that a nap can sometimes relieve a tension headache on its own. Other common triggers include:
- Poor posture, especially from long hours at a desk or looking down at a phone
- Eye strain from extended screen time or uncorrected vision problems
- Dehydration and skipped meals
- Jaw clenching or teeth grinding, which tightens the muscles on the sides of the head
Why Chronic Cases Feel Different
People with chronic tension headaches often notice that the pain spreads beyond its original location or feels more intense over time, even without an obvious injury. This happens through a process called central sensitization, where repeated pain signals cause real changes in how the brain and spinal cord process incoming information. The nervous system essentially turns up its own volume knob: excitatory pain signals get amplified while the body’s natural pain-dampening signals weaken.
Over time, a larger area of the nervous system gets recruited into the pain response, which is why chronic tension headaches can feel more widespread and persistent than the occasional episode. This isn’t imagined pain. It reflects measurable changes in nervous system function, and it’s one reason chronic tension headaches require a more comprehensive management strategy than just reaching for a pill.
How Tension Headaches Differ From Migraines
The biggest practical difference is that tension headaches let you function. You can still work, exercise, and get through your day, even if you’d rather not. Migraines typically force people to stop what they’re doing.
The strongest predictors that a headache is a migraine rather than a tension headache are nausea, severe or disabling pain, and sensitivity to light. About 60% of migraine sufferers also experience sensitivity to sound or smell. Migraine pain tends to be throbbing and often hits one side of the head, while tension headache pain is pressing, steady, and bilateral. Physical activity worsens migraines but has no effect on tension headaches. If you experience vision changes, tingling, or muscle weakness alongside your headache, that points toward migraine with aura rather than a tension headache.
Over-the-Counter Pain Relief
For the occasional tension headache, standard pain relievers work well. Ibuprofen tends to perform best in head-to-head comparisons. In clinical trials, 400 mg of ibuprofen provided better and faster pain relief than 1,000 mg of acetaminophen. A separate study found that 200 mg of ibuprofen was significantly better than 500 mg of aspirin at cutting headache intensity in half within one hour.
Acetaminophen and aspirin are also effective. Both outperform placebo, and at comparable doses they perform similarly to each other. Aspirin shows a clear dose-response pattern: 1,000 mg works better than 500 mg, which works better than 250 mg. The key is taking your chosen pain reliever early, when the headache is still building, rather than waiting until it’s fully established.
The Medication Overuse Trap
Here’s the counterintuitive problem: taking pain relievers too often can actually cause more headaches. Using simple over-the-counter painkillers more than 15 days a month, or combination pain relievers more than 10 days a month, puts you at risk for medication overuse headaches. This creates a cycle where the headache returns as the medication wears off, prompting you to take more, which makes the next headache come sooner. If you find yourself reaching for pain relievers more than twice a week, that’s a signal to explore other approaches.
Preventive Treatment for Chronic Cases
When tension headaches are frequent or chronic, the goal shifts from treating individual episodes to reducing how often they happen. A low-dose tricyclic antidepressant is the standard preventive medication for chronic tension headaches. It works by altering how the nervous system processes pain signals rather than by treating depression, and benefits typically become apparent after about three months of consistent use. The medication reduces both the frequency of headaches and the need for pain relievers.
Non-Drug Approaches That Work
Biofeedback and relaxation training are among the best-studied non-drug treatments. According to the American Migraine Foundation, these techniques can reduce headache frequency and severity by 45% to 60%. A 2025 systematic review confirmed that biofeedback significantly reduces both measures.
Biofeedback works by teaching you to control automatic body functions you’re normally unaware of. In one common approach, sensors placed on your forehead, jaw, and upper back muscles display real-time changes in muscle tension on a screen. You learn to consciously relax those muscles, which over time becomes a skill you can use at the first sign of a headache. Sessions typically run 30 to 60 minutes, and practicing at home about three times a week helps maintain the effect.
Mindfulness-based approaches are also gaining traction. Mindfulness-based cognitive therapy combines meditation and breathing exercises to promote relaxation, while acceptance and commitment therapy helps you respond differently to pain-related thoughts and feelings rather than bracing against them. For many people with chronic tension headaches, combining one of these techniques with occasional medication produces better results than either strategy alone.
Simple lifestyle adjustments can also reduce headache frequency: consistent sleep schedules, regular physical activity, staying hydrated, and taking breaks from screens every 30 to 60 minutes to release neck and shoulder tension. These changes won’t eliminate tension headaches entirely, but they lower the baseline of muscle tension and stress that makes headaches more likely to start.
