Other causes include pressure from wearing goggles, irritation to chemicals, changes in pressure from diving, dehydration, or simply exercise itself.
Here’s a closer look at different types of headaches related to swimming, how they differ from each other, and what can take away the pain.
Sinusitis
A common after-swim headache, sinus headaches are due to clogged sinus cavities, which can lead to infection and pain.
Sinus cavities can be irritated by swimming in chlorinated water. Changes in pressure from swimming underwater and diving can also lead to inflammation of the sinus cavity, or sinusitis.
Over the counter pain relievers, such as Tylenol (acetaminophen), Advil (ibuprofen), or Excedrin, or nasal sprays such as Afrin, can help relieve the pain. In the case of an infection, your healthcare provider will likely prescribe antibiotics.
Swimmer’s Ear
Otitis externa, also known as swimmer’s ear, is a bacterial ear infection of the outer ear canal. It occurs when water gets trapped in the ear. Symptoms include:
ItchingA feeling of fullness or fluid in the earPain in the head or jaw
Over the counter pain medications, like Tylenol or Advil, can help to relieve the pain, but in the case of an infection, your healthcare provider will likely prescribe antibiotic ear drops.
Using earplugs made for swimming can help you to prevent swimmer’s ear.
Tension Headache
Some headaches that occur after swimming are just run-of-the-mill tension headaches and not due to swimming at all. These are the most common type of primary headaches. They can be caused by heat, dehydration, bright sunlight, or skipping meals.
This type of headache typically responds well to over the counter pain medication, such as Tylenol or Excedrin.
Be sure to hydrate, eat nutritiously, take breaks from the sun, and consider wearing sunglasses when floating in the pool.
Migraine
Swimming can sometimes trigger a migraine. Swim-related migraines may begin as tension headaches, but take the pain to a greater level, with throbbing or pulsing.
Migraines are often accompanied by other symptoms that may include:
Nausea and vomitingBlurred visionLightheadedness that may lead to fainting
Migraines can resolve with Excedrin, though sometimes prescription medication is needed.
Compression Headache
A headache caused by applied pressure over the scalp or forehead, like from goggles or a tight swim cap, can cause a relatively unusual external compression headache.
According to the International Headache Society, this type of headache is constant, does not throb, and typically resolves after the pressure is alleviated.
Medication is not typically needed for this type of headache. However, if the pressure continues for a prolonged period, it may turn into a migraine.
Supraorbital Neuralgia
Another unusual type of headache, supraorbital neuralgia is a constant or spasmic pain in the supraorbital nerve in the forehead. Some people also experience numbness or tingling in the forehead as well with this type of headache.
Supraorbital neuralgia pain is treated with an anesthetic nerve blockade or nerve ablation.
If you suspect this type of headache, put goggles on gently, rotate different placement to avoid repeated pressure on the same spots, and try different goggles—ones with soft rubber and a smaller area of the seal around the eyes can reduce pressure.
Primary Exercise Headache
Strenuous swimming can cause primary exercise headaches, an exertional headache that throbs, lasts for less than 48 hours, and occurs during or after vigorous physical activity.
Studies suggest that these headaches are more common in females and typically aren’t accompanied by nausea or vomiting, though some researchers have found a prevalence in males. Hot weather and high altitudes can contribute to the pain.
In some cases, these episodes signal a previously undiagnosed underlying medical condition.
These headaches are typically treated with Tivorbex (indomethacin), a type of nonsteroidal anti-inflammatory medication, or NSAID.
Summary
Swim-related headaches are not uncommon and can occur for a variety of reasons. Sinusitis is sometimes associated with the water exposure from swimming. So is swimmer’s ear, which also may lead to headaches.
Less often, swimming can lead to a primary exertional headache, or a headache that’s been caused by compression from goggles or a tight swim cap.
If you experience a headache after swimming, speak to your healthcare provider. It’s important to ensure you have a proper diagnosis and begin any necessary treatment.
