Red light therapy for head pain: how to use a head wrap at home

It often arrives mid-afternoon: a dull pressure across your forehead, a band that seems to tighten around your head, and shoulders creeping up towards your ears after hours at a screen. If you've been searching for red light therapy for headaches, you've probably found bold promises and little practical detail. This guide covers the everyday headaches most of us get, simple steps that help, what the research on light and head pain does and doesn't show, how to use a head wrap at home, and when to see a doctor instead.

What are the most common everyday headaches?

There are many kinds of headache, but the one most people know best is the tension-type headache, often just called a tension headache. The Better Health Channel says it's the most common type of headache, and that two in three people will have at least one in their lifetime.

Healthdirect describes a tension headache as mild to moderate, usually on both sides of the head. It can feel like a constant dull ache, pressure pressing down on the top of your head, or a tight band around it. Your neck and shoulders may be sore too, and some people become sensitive to light or sound. It may ease after about half an hour, or last as long as a week.

The exact cause isn't clear. Healthdirect notes that these headaches aren't caused by muscle contractions, although muscle tension can make the pain worse. Common triggers it lists include:

• stress
• not getting enough sleep
• poor posture at work, at home or while driving
• eye strain from reading or screens
• bright or noisy surroundings
• dehydration
• caffeine withdrawal

A long day at a desk can stack several of these at once: hours of screen time, a slumped posture and a water bottle that never gets refilled.

What helps an everyday headache?

Most tension headaches settle with simple self-care. Healthdirect suggests:

• Rest and a proper break from what you were doing.
• Warmth and massage: a heat pack, or a gentle massage of your neck.
• Water, if you haven't had enough today.
• Everyday habits. Regular exercise, enough sleep, a balanced diet, better posture and ways to manage stress and relax can all help prevent them. Healthdirect also lists options such as physiotherapy and yoga.

If you're thinking about over-the-counter pain relief, ask your pharmacist what suits you, particularly if you take other medicines or have allergies.

If headaches keep coming back, Healthdirect suggests keeping a headache diary: note the days you have one, how bad it is, any other symptoms and possible triggers. It can reveal patterns, and it gives your GP something concrete to work with.

Does red light therapy help headaches?

The honest answer is that the research is too thin to say. Red light therapy, also called photobiomodulation, uses low-power red and near-infrared light. The leading theory is that cells absorb particular wavelengths, which may influence how they produce energy. The few trials of red light therapy for headaches have mostly used low-level lasers in a clinic, not LED devices at home.

One of the few placebo-controlled trials, published in 2005, involved 50 adults with long-term (chronic) tension-type headache. They had ten sessions of low-level laser on specific acupuncture points, three times a week, while a placebo group had the same procedure with the laser's power set to zero. Over the next three months, the laser group reported less intense, shorter headaches on fewer days than the placebo group. The researchers concluded laser acupuncture may help, but that larger, more rigorous trials were needed. The trial was also only partly blinded: participants didn't know which group they were in, but the researchers did.

A 2022 systematic review in the journal Life searched widely for randomised trials of light therapy for primary headaches (the kind not caused by another condition) and found only four. The 2005 trial was the only one that compared light therapy with a sham. Most of the trials had a high risk of bias, the certainty of the evidence was rated low, and the authors concluded the current evidence isn't enough to support using light therapy to reduce headache pain. They called for larger, better-designed trials.

So the evidence is limited and low in certainty, and none of it tested a home LED head wrap, which differs from a clinic laser in wavelength, power and positioning. If you try one, see it as one part of a routine that still includes the basics above.

How to use a head wrap for head pain

Always start with the directions for use that came with your device. As a general routine:

1. Sit somewhere quiet. A supportive chair or a corner of the couch is ideal. Don't use the wrap while driving or moving around, and don't fall asleep in it.
2. Position it over your forehead, temples and sides. Settle the wrap so the LEDs sit across your forehead and around your temples and the sides of your head.
3. Make it snug, not tight. You want even contact, not a wrap that squeezes your head.
4. Look after your eyes. The wrap sits on your forehead, close to your eyes. Don't look into the LEDs, close your eyes if the light feels bright, and follow the eye-protection instructions in the directions for use.
5. Run one session. Keep to the session length in the directions for use, and don't run back-to-back sessions to "top up". Our guide to how often to use red light therapy explains why longer sessions aren't better.
6. Use the time well. Try slow, steady breathing while the wrap runs, then finish with a few minutes of gentle neck turns and shoulder rolls.
7. Keep up the basics. A session isn't a reason to skip water, food or screen breaks.
8. Stop if it doesn't feel right. If the light or warmth feels uncomfortable, take it off. Don't use it over broken or irritated skin.

Bright light can feel unpleasant during some headaches, and Healthdirect notes that some people become sensitive to light during a tension headache. If you get migraine, or light bothers you when you have a headache, check with your GP before using any light device near your head.

When should you see a doctor about a headache?

A home device is for everyday head pain, not for working out what's causing it. Healthdirect advises calling triple zero (000) or going to the nearest emergency department if you have:

• a sudden, severe headache
• a headache with vomiting, confusion, a stiff neck or changes to your vision
• a headache with a fever, a change in personality, blurred or double vision, loss of balance or a seizure

See a doctor straight away if you have a headache:

• after a knock or injury to your head
• that has been getting worse over several weeks
• in the morning, with nausea that doesn't go away
• that's worse when you lie down, or that starts when you cough

If you're pregnant and have a sudden or unusual headache, speak to your doctor. It's also time to book in with your GP if your headaches are more frequent or severe than usual, get in the way of work, sleep or everyday activities, or need pain relief more than twice a week. For advice any time, call healthdirect on 1800 022 222 to speak with a registered nurse, 24 hours a day, 7 days a week.

About the Fringe Red Light Head Wrap

The Red Light Head Wrap is a wireless wrap with 450 LED chips that combine three wavelengths: 650nm red, and 810nm and 1050nm near-infrared.

It is included on the Australian Register of Therapeutic Goods (ARTG 469585), and our guide to checking a device on the ARTG shows you how to look up an entry yourself. The Red Light Head Wrap is intended to improve blood flow to relieve head pain. If your headaches are frequent or changing, see your GP before adding anything new to your routine.
