evidence: A widely circulated post on social media claims that between May 22 and 28, the sun is directly above the equator, referred to as the Equinox. The post further states that during this period, the body experiences rapid dehydration and advises people to drink more water. Let’s verify the claim made in the post. [...] Fact: 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. [...] Additionally, after looking into the matter, it has been discovered that the viral post has been circulating since 2016. However, experts in the field have stated that the claim made in the post about the equinox days causing rapid dehydration in the body is not supported by scientific evidence. They have called it a hoax and confirmed that there is no direct link between the occurrence of equinox and dehydration. Relevant articles can be read here, here and here.
