Sex headaches are a real medical condition that affects about one in every 100 people at some point in their lives. They can range from a dull ache that builds slowly to a sudden, intense pain that strikes at or just before orgasm. While they are usually harmless, sex headaches can sometimes signal a more serious problem with the blood vessels in the brain. This article explains what causes them, what symptoms to watch for, and how your doctor can help.
What Are Sex Headaches?
A sex headache is a type of headache that is triggered by sexual activity, most often by orgasm. Doctors also call them coital headaches or orgasmic headaches. They are more common than most people think, but many people feel too embarrassed to bring them up with their family doctor or at a walk-in clinic.
Men are about three times more likely than women to experience sex headaches. They also tend to occur more often in people who are prone to migraines. In most cases, these headaches are not dangerous. However, in some cases they can be a warning sign of something that needs immediate medical attention.
Types and Symptoms of Sex Headaches
There are two main types of sex headaches, and they feel quite different from each other. Understanding which type you are experiencing can help your doctor find the right cause and treatment.
The Gradual-Onset Type
This type starts as a dull, aching pain on both sides of the head. It builds slowly over several minutes as sexual excitement increases. Many people describe it as a feeling of pressure or tightening around the head and neck. This type is thought to be caused by muscle tension in the head and neck during sexual activity.
The Sudden-Onset Type
This type is far more abrupt. It strikes suddenly, often described as a thunderclap — an explosive or stabbing pain that hits just before or at the moment of orgasm. This is the type that requires the most attention. A sudden, severe headache during sex can occasionally point to a serious condition, such as bleeding in or around the brain.
In addition to these two main types, some people experience a low-grade headache that lingers for hours or even days after sexual activity. This is less common but worth mentioning to your doctor if it happens to you.
What Causes Sex Headaches?
Sex headaches have more than one possible cause, and the cause often depends on which type of headache you experience. Understanding the cause helps guide the right treatment.
Muscle Tension
The gradual-onset type is most often linked to the tensing of muscles in the head, neck, and scalp during sexual activity. As physical excitement builds, these muscles contract more and more. This increasing tension can produce a dull, squeezing headache.
Changes in Blood Pressure
The sudden-onset type is often connected to a sharp rise in blood pressure during orgasm. This rise can cause blood vessels in the brain to dilate rapidly. As a result, the sudden pressure change triggers an intense burst of pain.
Serious Underlying Conditions
In a small number of cases, a sudden sex headache can be caused by a more serious problem. These include a ruptured aneurysm, which is a bulge in a blood vessel that has burst, or bleeding between the brain and the surrounding tissue. This is called a subarachnoid haemorrhage. These conditions are medical emergencies.
For more information on how blood vessel problems affect headaches, see this overview from Mayo Clinic on sex headaches.
Other Associated Factors
Researchers have linked several other factors to sex headaches. These include:
Use of oral contraceptives
Cannabis use
Glaucoma (increased pressure in the eye)
Anaemia (low red blood cell count)
Sinus infections
Low blood sugar (hypoglycaemia)
A personal or family history of migraines
If any of these factors apply to you, let your doctor know when you describe your symptoms. This information helps them find the right diagnosis faster.
When to See a Doctor
Most sex headaches are not dangerous and do not need urgent care. However, there are certain situations where you should seek medical attention right away. Do not wait for a scheduled appointment if your symptoms are severe.
Go to your nearest emergency room or call 911 if your headache:
Comes on suddenly and feels like the worst headache of your life
Is accompanied by a stiff neck, fever, or confusion
Causes vision changes, weakness, or difficulty speaking
Is your very first sex headache and it is extremely severe
For less urgent cases, book an appointment with your family doctor or visit a walk-in clinic. This is especially important if sex headaches happen more than once, or if they are interfering with your quality of life. Your provincial health plan covers a visit to your family doctor or walk-in clinic for this concern, so there is no reason to put it off.
Furthermore, you should always see a doctor the first time you experience a headache during sex, even if the pain is mild. A first-time sex headache needs to be evaluated to rule out anything serious.
How Doctors Diagnose Sex Headaches
Your doctor will start by asking about your symptoms and medical history. From there, they may order one or more tests to look for any underlying cause. The tests used depend on how your headache presented and whether you have other symptoms.
MRI or CT Scan
An MRI (magnetic resonance imaging) scan uses magnetic fields and radio waves to create detailed images of the brain. A CT (computed tomography) scan uses rotating X-rays to produce cross-section images of the brain and head. Both tests can detect bleeding, tumours, or structural problems in the brain. Your doctor will recommend the most appropriate one based on your situation.
Cerebral Angiogram
An angiogram looks at the arteries in the neck and brain. In a traditional angiogram, a thin tube called a catheter is threaded through the blood vessels — usually starting at the groin — up to the arteries in the neck. A contrast dye is then injected so that X-ray images can show the arteries clearly. A less invasive version of this test uses an MRI or CT machine instead, without inserting a catheter.
Lumbar Puncture
A lumbar puncture, sometimes called a spinal tap, may be recommended if your headache came on suddenly. In this procedure, your doctor removes a small amount of fluid that surrounds the spinal cord and brain. This fluid is tested for signs of bleeding or infection. According to Healthline’s guide on coital headaches, a lumbar puncture is particularly important when a thunderclap headache occurs, because it can detect bleeding that may not show up on imaging scans.
Treatment Options for Sex Headaches
The good news is that many people only experience sex headaches once or twice. In those cases, no treatment is needed at all. However, if the headaches keep coming back, your doctor has several effective options to discuss with you.
Short-Term Pain Relief
In many cases, a sex headache passes so quickly that pain relievers do not have time to work. Therefore, over-the-counter pain relief is often not very useful for this condition. Your doctor may instead focus on prevention rather than treatment after the fact.
Preventive Medications
If you have a history of recurring sex headaches without a clear underlying cause, your doctor may recommend taking a preventive medication before sexual activity. Options include:
Indomethacin — a non-steroidal anti-inflammatory drug (NSAID) that can be taken about one hour before sexual activity
Triptans — a class of migraine medications that can also be taken about one hour before sex to help prevent headache onset
Beta-blockers — such as propranolol or metoprolol, taken daily to reduce the frequency of headaches; these are usually recommended only when episodes are frequent or long-lasting
Always speak with your doctor or pharmacist before starting any of these medications. Some have side effects or interactions with other drugs you may be taking. Your doctor can help you weigh the benefits and risks based on your personal health history.
You can also find general information about headache management from Health Canada, which provides trusted guidance on a wide range of health topics for Canadians.
Temporary Abstinence
There is evidence that continuing sexual activity shortly after a sex headache can make the pain worse. As a result, your doctor may suggest taking a break from sexual activity until the most recent headache episode has fully resolved. This is a temporary measure, not a long-term solution.
How to Reduce Your Risk
While sex headaches cannot always be prevented, there are some practical steps that may help reduce their frequency or intensity.
Take a more passive role during sexual activity, which reduces physical exertion and muscle tension
Stop sexual activity before reaching orgasm if you feel a headache beginning — this can sometimes prevent the headache from fully developing
Manage known risk factors such as high blood pressure, smoking, and cannabis use
Stay well hydrated and avoid sexual activity when you are overtired or unwell
Discuss migraine management with your doctor if you are prone to migraines, since the two conditions are often linked
In addition, keeping a simple log of when your headaches occur, how severe they are, and what you were doing beforehand can be very helpful for your doctor. This information makes it easier to identify patterns and find the most effective treatment plan for you.
Frequently Asked Questions About Sex Headaches
Are sex headaches dangerous?
Most sex headaches are harmless and go away on their own without treatment. However, a sudden, severe sex headache — especially one that feels like the worst headache of your life — can sometimes signal a serious condition such as a brain aneurysm or bleeding in the brain. Always see a doctor the first time you experience a headache during sex, just to be safe.
Why do I get a headache every time I have an orgasm?
Recurring sex headaches at orgasm are often caused by a sudden spike in blood pressure that causes blood vessels in the brain to expand rapidly. In some cases, muscle tension in the head and neck during sexual activity is also a contributing factor. If this happens to you regularly, speak with your family doctor — there are effective preventive medications available.
How long do sex headaches last?
Sex headaches vary in duration. Some last only a few minutes, while others can persist for several hours or even a day or two. The sudden-onset type triggered at orgasm tends to be intense but brief, whereas the gradual-buildup type may linger longer. If your headache lasts more than 24 hours, contact your doctor.
Can sex headaches be prevented?
Yes, sex headaches can often be prevented with the right approach. Taking a more passive role during sex and stopping activity before orgasm if you feel a headache starting may help. Your doctor may also prescribe preventive medications such as indomethacin or a beta-blocker if the headaches occur frequently.
Who is most at risk for sex headaches?
Men are about three times more likely than women to experience sex headaches. People who suffer from migraines also have a higher risk of developing this type of headache. Sex headaches can affect anyone, though, regardless of age or general health.
Should I go to the emergency room for a sex headache?
You should go to the emergency room if your sex headache is sudden and extremely severe, if it is accompanied by a stiff neck, fever, vision changes, or weakness, or if it is the first time you have ever experienced this kind of headache and the pain is intense. For milder or recurring sex headaches, a visit to your family doctor or a walk-in clinic is the right first step.
