If you’ve noticed your migraines are worse in summer, you’re not imagining it. A 2024 study found a 6% increase in headache frequency for every 10°F rise in temperature. And with Bucks County’s hot, humid summers — often punctuated by dramatic thunderstorms — migraine patients face a perfect storm of triggers.

Why Summer Triggers Migraines

Heat and Humidity

High temperatures cause blood vessels to dilate — and for people with migraines, this vasodilation can trigger the cascade of neurological events that produce an attack. Humidity compounds the problem by impairing your body’s ability to cool itself through sweating.

Barometric Pressure Changes

As we discussed in Day 3’s post on joint pain, falling barometric pressure before storms affects everyone — but for migraine sufferers, it’s one of the most commonly reported triggers. Studies find that 30-50% of people with migraines identify weather changes as a trigger. Those afternoon thunderstorms that roll through Doylestown in July? They’re not just dramatic — they’re neurologically provocative.

Dehydration

You lose more fluid through sweat in summer. Even mild dehydration can trigger migraines — and dehydration headaches can be harder to treat once they start.

Bright Sunlight and Glare

Photophobia (light sensitivity) is a core migraine symptom, and summer sun is intense. Glare off water, car windows, and pavement can trigger attacks even in people who don’t typically think of light as a trigger.

Disrupted Routines

Summer often means later bedtimes, different meal schedules, more alcohol at social events, and disrupted sleep — all of which are established migraine triggers.

Prevention: What You Can Do

Track Your Triggers

Keep a simple log for 2-4 weeks: date, weather (temp, humidity, storms), what you ate/drank, sleep quality, and whether you had a migraine. Patterns will emerge. You may discover that barometric pressure drops are your primary trigger, or that dehydration plus skipping lunch is a guaranteed formula.

Hydrate Proactively

By the time you’re thirsty, dehydration has already begun. Drink water consistently throughout the day. In high heat, add electrolytes — sodium and potassium help your cells retain water. For every caffeinated or alcoholic drink, add an extra glass of water.

Manage Light Exposure

• Wear polarized sunglasses — they reduce glare better than standard tinted lenses
• Use a wide-brimmed hat for additional shade
• Consider FL-41 tinted lenses (a rose-colored tint developed specifically for migraine-related light sensitivity)
• Take breaks from outdoor light — step into air-conditioned spaces periodically during long outdoor events

Keep a Consistent Schedule

Even on weekends and holidays, try to:

• Wake up and go to bed at consistent times
• Eat meals at regular intervals (skipping meals triggers migraines for many)
• Limit alcohol, especially red wine and dark liquors

Consider Preventive Medication

If you’re having more than 4 migraine days per month, preventive medication may be appropriate. Modern options include daily oral medications, monthly injectable CGRP inhibitors, and Botox for chronic migraine (15+ headache days/month). These are prescribed by neurologists or pain specialists, not primary care.

Acute Treatment: When a Migraine Hits

Act Fast

Migraine medications work best when taken at the very first sign — the prodrome phase. Don’t wait to see “if it’s really going to be a migraine.” Early symptoms may include yawning, neck stiffness, food cravings, or mood changes hours before head pain starts.

The Right Environment

At the first sign of an attack:

• Get to a cool, dark, quiet room
• Apply a cold compress to your forehead or neck
• Lie down if possible
• Avoid screens (phone, TV, computer)

Medication Options

• Triptans (sumatriptan, rizatriptan, etc.) remain first-line acute treatment for many patients
• Gepants (ubrogepant, rimegepant) are a newer class with fewer cardiovascular restrictions
• Anti-nausea medications if nausea is part of your attacks
• Avoid opioids and butalbital-containing medications for migraine — they cause rebound headaches and are not recommended by the American Headache Society

The Rebound Headache Trap

Taking acute medications more than 2-3 days per week can cause medication-overuse headache — a vicious cycle where the treatment becomes the cause. If you’re reaching for acute medication more than 10 days per month, you need preventive treatment.

When to Seek Specialist Care

• You have more than 4 migraine days per month
• Your migraines are getting worse or changing in character
• Over-the-counter medications don’t help
• You’re taking acute medication more than 2 days per week
• Your migraines come with neurological symptoms (vision changes, weakness, confusion)
• You’ve never had a formal migraine diagnosis

Local Resources

Doylestown Health and Jefferson Health both have neurology departments that can evaluate and treat migraines. At Cellara Pain Institute, while we focus primarily on spine, joint, and nerve pain conditions, we can help distinguish whether your headaches have a cervical (neck) origin — cervicogenic headaches mimic migraines but require different treatment — and coordinate with neurology colleagues.

Headaches shouldn’t own your summer. If you need migraine care, start with a consultation — we’ll help you find the right path forward.
