What barometric pressure level causes headaches?
Specifically, we found that the range from 1003 to <1007 hPa, i.e., 6–10 hPa below standard atmospheric pressure, was most likely to induce migraine. In the study by Mukamal et al. (2009), the mean atmospheric variation was 7.9 mmHg, which is consistent with our finding.

What is a bad barometric pressure for migraines?
20 change in the barometric pressure (e.g., from 30.05 to 29.85, or vice versa) triggers a migraine nearly every time, so I used . 20 as the threshold, and looked at the number of days per year a city reported a . 20 pressure swing in either direction.
What’s considered low barometric pressure?
A barometric reading below 29.80 inHg is generally considered low, and low pressure is associated with warm air and rainstorms. If the reading is under 29.80 inHg (100914.4 Pa or 1009.144 mb):
What is a high barometric pressure?
A barometer reading of 30 inches (Hg) is considered normal. Strong high pressure could register as high as 30.70 inches, whereas low pressure associated with a hurricane can dip below 27.30 inches (Hurricane Andrew had a measured surface pressure of 27.23 just before its landfall in Miami Dade County).
Why do I get a headache when a storm is coming?
During a storm, cold and warm air collide, creating an extreme difference in barometric (or air) pressure. This creates the elements of a thunderstorm, like wind and rain. The change in barometric pressure may be what triggers your headache, whether that is a migraine, tension-type headache, or a sinus headache.
Why do I get headaches when stormy?
If you’re prone to getting headaches, you could find that grey skies, high humidity, rising temperatures and storms can all bring on head pain. Pressure changes that cause weather changes are thought to trigger chemical and electrical changes in the brain. This irritates nerves, leading to a headache.
Are barometric pressure headaches real?
There is a link between atmospheric pressure and the amount of migraine pain some people experience. Atmospheric pressure, of course, is affected by weather. In fact, pressure headaches, sinus headaches, and barometric headaches may in some cases be examples of the weather affecting your migraines.
Is 29.7 low barometric pressure?
Ms. Vanos said people are most comfortable with barometric pressure of 30 inches of mercury (inHg). When it rises to 30.3 inHg or higher, or drops to 29.7 or lower, the risk of heart attack increases.
