Barometric Changes & Headaches

Barometric pressure, also called atmospheric pressure, refers to the pressure exerted by the weight of the atmosphere. According to the Mayo Clinic, several studies suggest that weather and atmospheric changes can trigger migraine headaches.

Expert Insight

• Changes in barometric pressure can bring about changes in headaches.

  A study conducted by researchers at Jefferson Medical College in Philadelphia found that migraines are more likely to occur with rises in barometric pressure. Rising temperatures were also found to impact migraine frequency.

Additional Weather Factors

• In addition to changes in barometric pressure, changes in weather patterns, temperature and humidity may also increase the frequency of migraine headaches. No clear evidence exists showing a correlation between weather and other types of headaches.

Effects

• Warmer temperatures may give rise to more headaches.

  Weather changes, such as increased temperatures in warm weather, may cause dilation of the blood vessels in the head. Dilated blood vessels have been identified as a cause of migraine.

Prevention/Solution

• By checking daily forecasts, migraine sufferers can anticipate weather changes that may bring on a headache. By recognizing weather triggers early, individuals can prepare by taking their medication at the first sign of migraine onset.

Treatments

• The Mayo Clinic identifies two categories of migraine treatment medications: pain-relieving and preventive. Taken after a migraine has begun, pain-relieving medications address symptoms that are already occurring. Preventive medications, usually taken on a daily basis, prevent headaches and reduce their frequency.
