A migraine is far more than just a headache. It is a complex neurological condition that affects approximately 1 billion people worldwide, making it the 3rd most common illness globally. Migraines involve changes in brain chemistry, nerve signalling, and blood flow that produce a cascade of debilitating symptoms.

The 4 Phases of a Migraine

Not everyone experiences every phase, but understanding them can help you recognise the early warning signs and intervene sooner:

• Prodrome (hours to days before): Subtle warning signs including mood changes, food cravings, neck stiffness, increased thirst, frequent yawning, and heightened sensitivity to light or sound. Recognising your prodrome can give you a critical head start on treatment.
• Aura (5–60 minutes): Occurs in roughly 25% of migraine sufferers. Typically involves visual disturbances such as zigzag lines, shimmering spots, or temporary blind spots. Some people experience tingling in the face or hands, difficulty speaking, or a sense of confusion.
• Headache (4–72 hours): The main attack phase. Usually intense, throbbing pain on one side of the head (though it can be bilateral). Accompanied by extreme sensitivity to light, sound, and smell, nausea, and sometimes vomiting. Physical activity tends to worsen the pain.
• Postdrome (up to 48 hours): Often called the “migraine hangover.” Symptoms include fatigue, difficulty concentrating, mood changes, lingering sensitivity, and muscle weakness. Many people feel drained or “washed out” during this phase.

Migraine With Aura vs. Without Aura

Migraine without aura is the most common type, accounting for about 75% of cases. The attack begins without the neurological warning signs of aura.

Migraine with aura includes distinct neurological symptoms — most commonly visual disturbances — that typically develop gradually over 5–20 minutes and last less than 60 minutes before the headache phase begins. People with aura may have a slightly elevated cardiovascular risk and should discuss this with their doctor.

Migraine triggers vary widely between individuals, but most fall into several common categories. Identifying your personal triggers is one of the most powerful steps toward reducing migraine frequency.

Environmental Triggers

• Bright or flickering lights (fluorescent lighting, sunlight glare)
• Loud or sudden sounds
• Strong smells (perfumes, cleaning products, smoke)
• Weather changes — barometric pressure drops, high humidity, extreme heat

Dietary Triggers

• Alcohol (especially red wine and beer)
• Caffeine withdrawal or excessive caffeine intake
• Aged cheeses, cured meats, and fermented foods (contain tyramine)
• MSG (monosodium glutamate) and artificial sweeteners (aspartame)
• Skipping meals or fasting — blood sugar drops can trigger attacks

Lifestyle Triggers

• Stress and emotional tension (and paradoxically, the “let-down” period after stress)
• Sleep disruption — both too little and too much sleep
• Dehydration — even mild dehydration can trigger attacks in sensitive individuals
• Hormonal changes — menstrual migraines affect up to 60% of women with migraines

Digital Triggers

• Prolonged screen time without breaks
• Blue light from monitors, phones, and tablets
• Poor ergonomics leading to neck strain and eye fatigue

Non-medication treatments for migraines are grounded in real science. Here is how each major approach works at a physiological level:

Neuromodulation

Devices like Cefaly and Nerivio use mild electrical impulses to alter nerve signalling. Cefaly targets the trigeminal nerve on the forehead — the primary nerve involved in migraine pain — delivering precise micro-impulses that desensitise the nerve and reduce its tendency to fire pain signals. Nerivio, worn on the upper arm, uses remote electrical neuromodulation (REN) to activate the body’s conditioned pain modulation system, where stimulating one area reduces pain perception in another (the brain).

Light Therapy & FL-41 Lenses

FL-41 tinted lenses filter specific wavelengths of light in the ~480–520nm range (blue-green spectrum) that are most likely to trigger photophobia and worsen migraines. Research shows these wavelengths activate melanopsin-containing retinal ganglion cells, which connect to the thalamus — a brain region that amplifies pain during migraines. By filtering these wavelengths, FL-41 lenses reduce the light-driven amplification of migraine pain.

Cryotherapy (Cold Therapy)

Cold therapy works through several mechanisms: it constricts blood vessels (vasoconstriction), reducing the throbbing sensation caused by dilated cranial arteries. It also reduces inflammation by slowing metabolic processes and decreasing the release of inflammatory mediators. Additionally, cold numbs pain signals by slowing nerve conduction velocity, providing direct analgesic effects.

Acupressure

Acupressure applies sustained pressure to specific points on the body. The two most evidence-backed points for migraines are LI4 (Hegu), located in the webbing between thumb and index finger, and P6 (Nei-Kuan), on the inner wrist, which is particularly effective for migraine-related nausea. The mechanism is explained by the gate control theory of pain: pressure stimulation activates large nerve fibres that “close the gate” on pain signals from smaller fibres, reducing pain perception in the brain.

Aromatherapy

Menthol and peppermint oil activate TRPM8 receptors (cold-sensing receptors) in the skin, producing a cooling sensation that can reduce pain perception and improve blood flow. A clinical study found that topical peppermint oil was as effective as paracetamol for tension-type headaches. Lavender oil has been shown to reduce cortisol levels (the stress hormone) and activate the parasympathetic nervous system, promoting relaxation and reducing stress-triggered migraines.

Supplements

Magnesium plays a critical role in preventing cortical spreading depression (CSD) — the wave of electrical activity across the brain that triggers the aura phase and subsequent headache. People with migraines often have lower magnesium levels. Riboflavin (Vitamin B2) supports mitochondrial energy production in brain cells; impaired mitochondrial function is thought to increase migraine susceptibility, and 400mg daily of riboflavin has been shown to reduce migraine frequency by up to 50%.

Match your predominant symptoms to the non-medication treatments with the strongest evidence:

Consistency is key for migraine prevention. Here is a framework you can adapt to your own schedule and needs:

Warning Signs Requiring Immediate Medical Attention

Seek emergency care if you experience:

• Thunderclap headache — the worst headache of your life that peaks within seconds
• New neurological symptoms — sudden weakness, numbness, vision loss, confusion, or difficulty speaking
• Headache with fever, stiff neck, or rash — may indicate infection such as meningitis
• Headache after head trauma — even if it seems mild
• Dramatic change in headache pattern — especially after age 50

What to Expect at a Neurology Appointment

A neurologist will review your headache history, frequency, and symptoms. Bring your migraine diary if you have one. They may order imaging (MRI or CT scan) to rule out other causes, and will discuss both preventive and acute treatment options. Be prepared to describe your typical attack from start to finish, including any triggers you have identified.

How Non-Medication Treatments Complement Prescriptions

Non-medication treatments are not an either/or choice with prescription medications. Many neurologists actively recommend combining approaches. For example, a patient might take a prescribed preventive medication while also using FL-41 glasses for light sensitivity, an ice cap for acute relief, and magnesium supplements for additional prevention. This multi-modal approach often provides better outcomes than any single treatment alone.
