evidence: Equinoxes typically occur around the 20th of March and the 22nd of September each year. During these times, the Sun passes directly above the equator, resulting in nearly equal amounts of day and night worldwide. However, there is no scientific evidence to support the claim that equinoxes directly cause rapid dehydration. However, it is important to emphasize that maintaining proper hydration is crucial not only during the equinox but also on any other day, especially during the summer seasons. Hence the claim made in the post is MISLEADING.
