Why Does Crying Give You Headaches? Explained

If you have ever cried hard and then felt a pounding headache settle in behind your eyes or across your forehead, you are not imagining it. Crying can genuinely cause headaches through a mix of muscle tension, sinus pressure, and changes in blood flow around the head and face. The headache is usually a tension-type headache or a sinus-related pressure feeling, and it typically eases within an hour or so after you stop crying and calm down.

The short answer comes down to what happens in your body during a good cry — and it is more mechanical than emotional. Your facial muscles tighten, your sinuses fill with fluid, and your breathing changes. Each of those can contribute to head pain.

Why Does Crying Give You Headaches?

Crying triggers several physical changes at once, and together they can produce head pain.

The first is muscle tension. When you cry, you scrunch your forehead, squeeze your eyes shut, and tighten your jaw and neck. Holding those muscles tense for several minutes is enough to cause a tension-type headache. This is the same kind of headache many people get from staring at a screen or clenching their jaw during a stressful day.

The second is sinus pressure. Tears drain through small channels that connect your eyes to your nasal cavity. When you cry heavily, those passages can become congested, and the sinuses around your nose and eyes fill with fluid. That pressure is often felt as pain across the cheeks, forehead, and behind the eyes.

The third is blood flow. Emotional crying activates the sympathetic nervous system — the “fight or flight” branch — which can narrow and then widen blood vessels. Some researchers think this shifting blood flow plays a role in the throbbing quality many people notice after intense crying.

None of these mechanisms is dangerous on its own. They are normal responses to a normal behavior.

What Kind of Headache Does Crying Cause?

Most crying-related headaches look like tension-type headaches. The pain is usually dull, pressing, or tight, and it affects both sides of the head rather than just one. It often sits across the forehead, the temples, or the back of the neck.

Some people describe a sinus headache instead — a feeling of pressure and fullness around the eyes, cheeks, and bridge of the nose. This is not always a true sinus infection. It can simply be congestion from crying.

A smaller number of people get a throbbing headache after crying, especially if they are prone to migraines. Emotional stress is a well-recognized migraine trigger, and crying is one form of emotional stress. For those people, crying may set off a migraine rather than a simple tension headache.

It helps to know which pattern you tend to get. A dull, band-like pressure points to tension. Throbbing on one side with nausea or light sensitivity points more toward migraine.

Why Do Your Eyes and Sinuses Hurt After Crying?

The eye and sinus pain that comes with crying has a straightforward physical explanation. Tears are produced by glands above the outer corner of each eye and drain through tiny openings at the inner corner. From there, they flow into the nasal cavity.

When you cry a lot, that drainage system gets overwhelmed. The tissue lining your nose swells, and your sinuses — the air-filled spaces in your cheekbones, forehead, and around your eyes — can become congested. Congestion creates pressure, and pressure in the sinuses is felt as pain or aching in the face and head.

Your eyelids also get puffy and heavy after prolonged crying. Swelling around the eyes can make the whole area feel sore and tender.

This is why some people reach for a cold compress or a warm shower after a hard cry. Cooling the area can reduce swelling, and steam can help loosen nasal congestion.

Does Crying Always Cause Headaches?

No. Many people cry without getting a headache at all. Whether you get one depends on several factors.

• How long and how hard you cried
• How tense your face, jaw, and neck muscles get during crying
• Whether you already get tension headaches or migraines
• How congested your sinuses tend to be
• Whether you are dehydrated or have not slept well

Someone who cries briefly and then relaxes may feel nothing. Someone who sobs for twenty minutes with a clenched jaw and blocked sinuses is more likely to end up with a headache.

People who get frequent headaches in general — including those with a migraine diagnosis — tend to be more sensitive to crying as a trigger. That does not mean crying is harmful. It means their nervous system is already primed to react to stress and physical strain.

How to Relieve a Headache After Crying

Most crying headaches ease on their own within an hour or so. A few simple steps can help speed that up.

Relax your face and jaw. Unclench your teeth, drop your shoulders, and gently massage your temples, forehead, and the base of your neck. This directly targets the muscle tension that builds during crying.

Address sinus congestion. A warm shower, a saline nasal rinse, or a warm compress over the cheeks and forehead can help reduce pressure. Staying hydrated also helps thin mucus.

Rest in a calm, dim room. If you are prone to migraines, lying down in a dark, quiet space with your eyes closed can ease both the pain and any light sensitivity.

Consider over-the-counter pain relief if you need it. Common pain relievers such as acetaminophen or ibuprofen are used for tension-type headaches. Follow the label directions, and check with a doctor or pharmacist if you take other medications or have health conditions. These medicines are not appropriate for everyone, and they are not meant for frequent, long-term use without medical guidance.

If crying headaches happen often, or if the pain is severe or comes with symptoms like vomiting, vision changes, confusion, or a stiff neck, that is a reason to see a doctor. Those symptoms are not typical of a simple crying headache.

Is a Headache After Crying a Sign of Something Serious?

In most cases, no. A headache after crying is a normal response to muscle strain and sinus pressure. It is not a sign of brain damage, a tumor, or any hidden disease.

That said, headaches in general can sometimes signal a medical problem, and crying is not always the cause. Seek medical attention if a headache:

• Comes on suddenly and severely, like a thunderclap
• Is the worst headache of your life
• Comes with fever, stiff neck, or rash
• Comes with weakness, numbness, slurred speech, or vision loss
• Follows a head injury

These warning signs apply to headaches from any cause, not just crying. They are worth knowing because they are the situations where waiting is not a good idea.

Can Crying Actually Help a Headache?

Sometimes, yes — and this is a point many people find surprising. Crying releases emotional tension, and for some people that relief can ease a stress-related headache rather than cause one.

Emotional crying also triggers the release of endorphins, the body’s natural pain-relieving chemicals, along with oxytocin. Some research suggests these chemicals may help calm the nervous system after crying. The evidence on crying as a mood or pain regulator is mixed, though. Studies have found that crying does not reliably improve mood for everyone, and the after-effects vary a lot from person to person.

So crying can go either way. For some people it releases tension and leaves them feeling lighter. For others it leaves behind a tight, achy head. Both responses are normal.

The Bottom Line

Crying gives you a headache because of what your body physically does while you cry: your face and jaw muscles tighten, your sinuses fill with fluid, and your blood flow shifts. The result is usually a tension-type or sinus-pressure headache that fades within about an hour.

It is not a warning sign of anything serious in most cases. Simple steps — relaxing your face, easing sinus congestion, resting, and staying hydrated — usually help. If crying headaches are frequent or severe, or come with other symptoms, talk to a doctor.
