Winter weather often brings with it a surge in migraine occurrences for many individuals. Conditions like rain, dry air, and fluctuating barometric pressure are known to trigger these debilitating headaches. Dr. Sachi A. Mehrotra, an Orofacial Pain Specialist, explains that these environmental changes can disrupt the chemical balance within the sinuses, leading to migraines. The science behind this is complex, with barometric pressure changes affecting sinus pressure, dry air causing dehydration, and shorter days disrupting serotonin levels and circadian rhythms. Lifestyle changes during the holiday season, such as increased stress, altered sleep patterns, and dietary changes, further exacerbate migraines.
