Calgary’s warm chinook winds are often linked to headaches by many individuals, although experts suggest that the scientific explanation for this connection remains uncertain. Dr. Serena Orr, a pediatric neurologist and associate professor at the University of Calgary’s Cumming School of Medicine, emphasized the lack of conclusive evidence regarding the relationship between pressure and headaches.
A study published in the medical journal Neurology in 2000 established that chinooks can increase the likelihood of migraines in some people, indicating that chinook headaches are more than just anecdotal experiences. Dr. Orr, specializing in headaches, proposed that the correlation likely involves altitude and barometric pressure, which is the atmospheric weight force.
Calgary, situated over 1,040 meters above sea level, is recognized as a high-altitude location, with the highest elevation among major Canadian cities. Despite the association between altitude and migraine prevalence, Orr noted that this link has not been definitively proven.
While research on rodents suggests that changes in barometric pressure can cause pain and stress through their inner ear systems, Orr emphasized that this phenomenon has not been thoroughly studied in humans. A study conducted in November 2025 by Orr and fellow researchers on the impact of chinooks on migraines in youth did not find a significant connection between the two, contrary to expectations based on previous adult studies.
Further investigation is deemed necessary to understand why the latest study’s outcomes diverged from previous findings that supported a link between chinooks and headaches. Orr suggested that analyzing individual weather parameters rather than just classifying days as chinook or non-chinook might provide more insights. Additionally, she speculated that age could influence how the brain reacts to weather changes over time.
In Japan, Dr. Toshiyuki Hikita, a practitioner in Gunma Prefecture, highlighted the absence of evidence linking the cool katabatic winds known as oroshi to headaches. Hikita discussed the impact of typhoons on migraines, noting that weather events like typhoons and chinooks, characterized by drops in barometric pressure, can trigger migraines in susceptible individuals.
Hikita’s observations emphasized the role of weather factors like humidity and rainfall in exacerbating headaches. He differentiated between the effects of chinooks and oroshi, noting that while both are strong mountain winds, chinooks induce migraines under specific conditions, unlike oroshi. Orr intends to delve deeper into the relationship between chinooks and headaches in upcoming research, focusing on individual weather parameters to enhance understanding of migraine biology through weather-related studies on animals and humans.
