Can Steam Rooms Relieve Headache Symptoms?

A steam room may relieve some headache symptoms, mainly tension-type headaches linked to tight neck and shoulder muscles, but it can trigger or worsen others, especially migraine. Moist heat relaxes tight muscles, and warm, humid air can make a stuffy nose feel clearer for a while. But heat, humidity, and dehydration are also common migraine triggers.

The type of headache decides most of the answer. A steam session that eases one person's afternoon headache from a stiff neck can turn another person's early migraine into a full attack.

How Might a Steam Room Ease Headache Discomfort?

Mostly through warmth, which helps tight neck and shoulder muscles let go. Moist air and a few quiet minutes help too, though none of it lasts long after you step out.

The warmth matters because tight muscles in the neck, shoulders, and scalp can set off a tension-type headache.

Humid air works on the nose instead. Steam keeps the lining of the nose from drying out, and you may feel less blocked while you breathe it. The relief is real but short, and it doesn't clear whatever is causing the congestion.

Then there's the quiet. Stress is a frequent headache trigger, and a steam session is one of the few places where a phone stays outside. Sitting still with your eyes closed in a warm, quiet room gives the body a chance to downshift.

Does the Type of Headache Make a Difference?

The answer is yes. Tension-type headaches are the most likely to improve in a steam room, sinus-area pressure may ease briefly, and migraine is the type most likely to get worse.

Tension-Type Headaches

Tension-type headaches are the most likely to respond to steam. They are the most common headache disorder worldwide, according to the  World Health Organization, and usually feel like a band of pressure around the forehead, temples, or back of the head, often with sore neck and shoulder muscles. Heat helps with that tightness. A heating pad, warm compress, or hot shower is among the self-care steps for tension headaches, and a steam room works on the same muscles.

The quiet of a steam session also helps with the stress that often comes with these headaches. If your headache started after hours at a desk, a long drive, or a tense day, a short steam session is a reasonable thing to try. Gentle neck and shoulder stretches afterward, while the muscles are still warm, can add to the effect.

Migraine

Migraine is the headache type where a steam room is most likely to backfire. The American Migraine Foundation counts excessive heat among common weather triggers, and about a third of people with migraine say dehydration sets off their attacks. A steam room combines heat, high humidity, and fluid loss in one small space.

During an attack, light and sound often make the pain worse, suggesting resting in a dark, quiet room with a cold or warm pack on your head or neck. A steam room gives you the quiet but adds heat at the worst possible time. If you live with migraine, avoid the steam room when you feel one starting.

Headaches With Sinus Pressure or Nasal Congestion

Headaches with sinus pressure may ease for a short time in a steam room, because warm, moist air helps a stuffy nose feel more open.

The evidence is modest. In a 2016 randomized trial of 871 primary care patients with chronic or recurrent sinus symptoms, advice to use steam inhalation did not improve overall sinus symptoms, although it did reduce headache ( Little et al., CMAJ, 2016 ). 

Before you steam, make sure it really is a sinus headache. About 90% of self-diagnosed sinus headaches turn out to be migraine, according to the American Migraine Foundation . If your "sinus headache" comes with nausea, sensitivity to light, or throbbing on one side, treat it as a possible migraine and skip the steam.

Can a Steam Room Cause or Worsen a Headache?

This is entirely possible, usually because you've lost too much fluid or gotten too hot. Most of these headaches are mild and easy to prevent.

You sweat heavily in a steam room, and because the air is already saturated, sweat drips off instead of evaporating and cooling you. Start a session dehydrated, or after a drink or two, and a dull dehydration headache can follow.

Overheating is the more serious cause. Headache is one of the warning signs of heat exhaustion, along with dizziness, nausea, heavy sweating, weakness, and fainting, according to the Centers for Disease Control and Prevention (CDC). A headache that starts during a session, especially with any of those symptoms, is a signal to leave the steam room, cool down, and drink water.

Other triggers are easy to overlook. Strong essential oils such as eucalyptus or peppermint can set off headaches in people sensitive to smells. Skipping a meal before a session can bring one on too, and so can stepping straight from the heat into cold air if you're prone to headaches. 

What Should You Consider Before Using a Steam Room With a Headache?

Start with what kind of headache you have. Steam is worth trying for a familiar tension-type headache, and a poor choice for a migraine, a new or unusual headache, or a headache with fever. After that, check your fluids and any health condition that makes heat risky for you.

A few habits make a session safer:

• Drink water before and after, and skip alcohol around your session.

• Keep sessions to 10 to 15 minutes, and closer to 5 to 10 the first time you try steam for a headache. A moderate setting around 110°F to 114°F (43°C to 46°C) is plenty.

• Leave out essential oils if scents bother you.

• Get out at the first sign that the headache is getting worse, or if you feel dizzy, nauseated, or weak.

• Cool down gradually, and eat something if you have not eaten for a while.

Talk to your doctor before using a steam room if you are pregnant, have heart disease, have low or uncontrolled blood pressure, or take medications that affect sweating or fluid balance.

A home steam room makes these choices easier. In a public spa, it's easy to stay in longer than you meant to, or end up sitting next to someone's eucalyptus oil. At home, you decide whether any scent goes in, and you can step out the second a headache starts to build. GeyserSteam makes indoor steam rooms for one person (the Beppu) up to six to eight (the SteamHaus), plus custom builds for unusual spaces. Still, a steam room is a comfort measure. Headaches that keep coming back need a proper diagnosis.

Create Your Personal Wellness Space at Home 

Most headaches, including the occasional one after a long steam, fade with water, rest, and time. Some need a doctor, and a few need one right away.

If a headache:

• Hits suddenly and severely, or is the worst you've ever had

• Follows a blow to the head

• Comes with confusion, fainting, or trouble seeing, speaking, walking, or understanding speech

• Comes with numbness, weakness, or paralysis on one side of the body

• Comes with a high fever, a stiff neck, or vomiting that isn't clearly from the flu or a hangover

In a steam room, also watch for heat stroke. A headache with confusion, hot skin, or fainting during or after a session can be heat stroke, which the CDC calls a medical emergency: get out of the heat and call 911. Milder heat exhaustion usually improves once you cool down and sip water. Get medical help if you're vomiting, your symptoms get worse, or they last longer than an hour.

Book a regular appointment if your headaches come more often or hurt more than usual, don't improve with over-the-counter pain relievers, or keep you from work, sleep, or your normal routine. Knowing which type of headache you have also helps determine whether a steam room is worth trying.
