As the weather and humidity in central Illinois make it feel more and more like the temperature is over 100°F outside, the IDHH is highlighting the proverbial “dog days” of summer. While the phrase “dog days” or “dog days of summer” might be somewhat familiar, just what are these days and how did this expression enter our cultural lexicon? From an astronomical point of view, the phrase refers to the annual phenomenon in which the bright star Sirius rises into the sky at the same time as the Sun. This heliacal rising allows viewers to see both the Sun and the Sirius star simultaneously, leading to the belief that Sirius intensified or added to the Sun’s heat. In the Northern Hemisphere, this simultaneous rising may be seen during the hottest months of the year, in July and August.
Hellenistic astrologers in the Mediterranean were aware of the star Sirius, calling it the “Dog Star” due to the way it followed the constellation Orion into the night sky. The sweltering and humid weather in the Mediterranean during these months would often cause people to fall ill, and so the connection was made between Sirius’ heliacal rising and its effect on the populations below. A variety of detrimental effects to human activities were attributed with Sirius’ rising such as lethargy, fever, and bad luck, as well as the belief that this hot period brought out madness in dogs, further reinforcing the notion of the “dog days”. While we may no longer blame a summer fever on the “dog days of summer”, there is no denying the potent influence of a heat wave in July to inspire lazy dreams of a nice afternoon spent on the water. Between numerous lakes and ponds, miles of river, and spots like Navy Pier on the shores of Lake Michigan, Illinoisians have plenty of ways to cool down during the hot summer.
Below are a few of our favorite items highlighting ways to enjoy the “dog days of summer” and beat the heat:
On January 28, 1969, an underwater oil well drilled off the coast of Santa Barbara, California suffered a blowout six miles from the coastline. Oil seeped out of the ocean floor bedrock at a rapid rate, creating an oil slick that would extend across dozens of square miles. The largest oil spill in American waters at the time, an estimated 3 million gallons of crude oil spilled into the Santa Barbara Channel over the course of the next month. The impact on the local marine environment was extreme as thousands of sea birds and marine animals were killed, and the clean-up efforts took months to address the damage of the spill. The enormity of this environmental disaster, and the increased awareness among Americans in the 60’s of environmental concerns generally, would prompt President Nixon to sign the National Environmental Policy Act in 1969 and inspire the creation of an annual Earth Day.
Held on April 22, 1970, the first Earth Day was conceived as an “environmental teach-in” that would educate citizens about the importance of environmental conservation. The product of collaboration between Wisconsin senator Gaylord Nelsen and activist Denis Hayes, the day eventually abandoned the “teach-in” model and saw numerous demonstrations and protests across the United States as more than 20 million people organized in city streets, which is still the largest organized demonstration in American history today. Over fifty years later, Earth Day is an annual reminder on April 22 to support efforts protecting our ever-changing environment and to contribute to a more sustainable world.

As a native Texan, I have always regarded winter sports with a healthy amount of both respect and fear. However, an exception to this innate mindset was made every four years with the performance of the Winter Olympics. For those few weeks, I was awed by the grace of the figure skaters, the fearlessness of the luge racers, and the gravity-defying feats of snowboarders in the half-pipe. With the winter season in full swing here in Illinois, and the 2022 Winter Olympics just around the corner, the IDHH would like to feature a staple winter sport: ice skating.
Ice skating is believed to have developed in Scandinavia as early as 1000 BCE, using skates initially made from the bones of elk, oxen, reindeer, and other animals. While it is not exactly known when metal blades were introduced in the construction of ice skates , Dutch paintings from the 17th century clearly depict skaters gliding along on metal blades. Gaining in popularity as a recreational pastime in the 1800s, the activity eventually reached North America and a number of skating clubs were established in major cities in the Northern Hemisphere. Toward the end of the century, the sport would be indelibly changed in 1876 with the creation of the first rink using artificially frozen ice – the Glaciarium in London. The artificial ice rink in Madison Square Gardens opened soon after in 1879 and the innovation of creating artificial rinks led to the rise of various skating sports and a desire for ice shows as popular entertainment. Eventually, ice skating would make its debut in the 1908 Summer Olympics, with speed skating to follow as an event at the first official winter games in 1924.
Whether a newcomer to skating or a veteran of the ice, please enjoy a few of our favorite ice skating items from the collection:
