The difference between headaches and migraines

People often tend to lump headaches and migraines into the same bucket, says headache specialist Jennifer Kriegler, MD.  “Many think migraines are just really bad headaches, which is not altogether true,” she says. “Headaches and migraines can have different causes.”

Headaches of any level of pain can be symptoms of a migraine attack, but a migraine is actually a neurological disease or brain imbalance that causes a lot of other symptoms in addition to headaches.

These include sensitivity to light, nausea and vomiting, stomach upset, abdominal pain, loss of appetite, dizziness, blurred vision, numbness, tingling or weakness in rare cases.

Migraine episodes result from different signals interacting with your brain, blood vessels and surrounding nerves which cause any of the symptoms above. During a migraine headache in particular, specific nerves of the blood vessels are activated and send pain signals to the brain.

How weather brings on a migraine headache

Research shows that changes in weather patterns are tied to changes in barometric pressure and temperature, and in turn this can be associated with the onset of mild to severe headaches.

“For some people, it’s a fall in barometric pressure, for others, it could be a quick rise in temperature. Either way when these pressure changes occur most commonly during a storm, a headache can be triggered,” Dr. Kriegler says.

For what we consider to be the effect of weather on migraines, we’re most likely talking about how weather can contribute to the headache part of a migraine episode.

During a storm, cold and warm air mix to create variations in barometric (or air) pressure.  This also is how wind, rain and thunderstorms are created. Barometric pressure is also known as the atmospheric pressure being applied against a given area — and in this case that “area” is you.

Because your nasal and sinus cavities are air channels any change in that pressure, especially a fall in barometric pressure, affects those areas. This forces fluid into tissues and can cause a disruption in fluid balance.

Some researchers also think the barometric change may affect the pressure on your brain and how the way your brain blocks or doesn’t block pain.

7 ways to ward off headaches

“Weather is certainly not the only reason we get headaches. Stress, specific over-the-counter medicines like analgesics or pain killers, hormonal triggers and certain disorders related to sleep for example may also be causes,” Dr. Kriegler says.

“And while you can’t control the weather, you can take steps to minimize the your risk, severity and treatment of a headache or migraine attack by following some best practices.”

  1. Avoid other triggers when the weather is bad — Stay away from foods that cause migraines, like those that contain caffeine, monosodium glutamate (MSG) and nitrates and you’ll remove one other trigger factor from the mix.
  2. Keep rescue medications handy —  Discuss these medications with your doctor. If you haven’t tried rescue medications before, ask your doctor what is available.  If you know certain drugs work for you, make sure your prescriptions are up to date to have them at the ready.
  3. Ask about preventive options — If you go through an especially bad period of migraines, your doctor may want to try medications or other treatments designed to keep migraines at bay before they happen. Sleep deprivation or other sleep issues for example can contribute to a higher frequency of headaches, so it’s important for you to increase the amount you get each night.
  4. Manage your stress — As barometric pressure falls, people who suffer from migraine headaches will often sense it and become stressed, according to Dr. Kriegler. Stress hormones also can provoke a headache. Managing stress through exercise, lifestyle changes, deep breathing or relaxation techniques will help ward it off.
  5. Increase your magnesium — For some people, increasing magnesium prior to a weather change may help limit or prevent a migraine too. Try eating more dark leafy greens, fish, soybeans, avocado and bananas, which are good natural sources of magnesium.
  6. Drink more water — Fluid shifts in blood vessels surrounding the brain can cause a headache, so it’s important to stay hydrated. “Drink lots of water, especially before you go outside and in warmer weather,” Dr. Kriegler says. “On a hot 90 degree humid day you can lose up to a liter of fluid an hour, so you really have to maintain your fluid balance.”
  7. Wear sunglasses — Besides storms, Dr. Kriegler says bright light and glare from a sunny day or light flickering through trees while someone is driving can also trigger a migraine headache.

“If you seem prone to migraine headaches or if they are disrupting your life, be sure to talk to your doctor,” Dr. Kriegler says. “He or she will work with you to identify triggers as well as the best treatments.”
