Why Do They Say Dog Days Of Summer? Exploring The Origin And Significance

Have you ever wondered why we refer to the hottest days of summer as the “dog days”? This unique term finds its origins in the appearance of the star Sirius in the sky. Sirius, often referred to as the “dog star,” would become visible just before sunrise, typically around the end of July. This celestial event marked the onset of the sweltering summer heat. The Romans, recognizing this correlation, coined the term “dies caniculares,” meaning “days of the dog star.” Over time, this phrase was translated into the more familiar “dog days,” a term we still use today to describe the scorching days of summer.

“Why can’t you swim during the dog days?” This question stems from the age-old belief that the “dog days” of summer, typically occurring during the hottest part of the year, come with some peculiar and potentially harmful characteristics. Historically, it was thought that during these scorching days, which typically run from early July to early August, “all liquids are poisonous.” This belief was rooted in the observation that stagnant water sources could breed harmful bacteria and become unsafe to drink. Additionally, it was believed that during this period, activities like bathing, swimming, or even drinking water could be risky due to concerns about heat-related illnesses and waterborne diseases. The notion was that wounds and sores might not heal properly during this time as well. While these beliefs may have originated from folklore and superstition, they serve as a reminder of the historical challenges and perceptions surrounding the intense heat of the dog days.
