The foundation cited a 2023 study of more than 15,000 migraine sufferers in Japan that linked an increase in headaches during barometric pressure changes, humidity and rainfall.
The first publication to document a change in pain perception associated with the weather was the American Journal of the Medical Sciences in 1887. This involved a single case report describing a person with phantom limb pain, and it concluded that "approaching storms, dropping barometric pressure and rain were associated with increased pain complaint."
Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa ), which is equivalent to 1,013.25 millibars , [ 1 ] 760 mm Hg , 29.9212 inches Hg , or 14.696 psi .

Referred pain from barosinusitis to the maxilla consists about one-fifth of in-flight barodontalgia (i.e., pain in the oral cavity caused by barometric pressure change) cases. [11] [12] Although the environment of fighter pilots produces the most stressful barometric changes, commercial flying has changed the picture of the disease.
One exception is barodontalgia manifested as referred pain from barosinusitis or barotitis-media. The latter two conditions are generated from pressure changes rather than pressure-related flare-up of pre-existing conditions. [14] A meta-analysis of studies conducted between 2001 and 2010 [15] revealed a rate of 5 episodes/1,000 flight-years.
The physics that affect the body in the sky or in space are different from the ground. For example, barometric pressure is different at different heights. At sea level barometric pressure is 760 mmHg; at 3,048 m above sea level, barometric pressure is 523 mmHg, and at 15,240 m, the barometric pressure is 87 mmHg.
