Heatwaves Can Affect Your Ability to Think Clearly and Make Decisions

Dehydration and body odor aren't the only things to hate about oppressive heat. According to new research reported by The Guardian, living through a heatwave without relief hampers your ability to think quickly and clearly.

For their study, published recently in PLOS Medicine, researchers at the Harvard T.H. Chan School of Public Health tested the mental performance of 44 students during a heatwave in Boston in 2016. Roughly half the students were living in newer dorm buildings with central AC, with the other half living in older dorms without it.

Over 12 days, researchers had participants take cognition tests on their phones immediately after waking up. The students living without AC took about 13 percent longer to respond to the questions and their answers were about 13 percent less accurate.

The results indicate that even if high temperatures don't pose an immediate threat to someone's health, they can impair them in other ways. “Most of the research on the health effects of heat has been done in vulnerable populations, such as the elderly, creating the perception that the general population is not at risk from heat waves,” Jose Guillermo Cedeño-Laurent, research fellow at Harvard Chan School and lead author of the study, said in a statement. “Knowing what the risks are across different populations is critical considering that in many cities, such as Boston, the number of heat waves is projected to increase due to climate change.”

Summers are gradually becoming hotter and longer in Boston—a trend that can be observed throughout most of the rest of the world thanks to the rising temperatures caused by human activity. In regions with historically cold winters, like New England, many buildings, including Harvard's oldest dorms, are built to retain heat, which can extend the negative effects of a heat wave even as the weather outside starts to cool. If temperatures continue to rise, we'll have to make a greater effort to keep people cool indoors, where American adults spend 90 percent of their time.

Our thinking isn't the only thing that suffers in the stifling heat. A study published last year found that hot weather does indeed make you crankier—which may not be as bad as bombing a test, but it's not exactly not fun for the people around you.

Everyone should have a few good board games lying around the house for official game nights with family and friends and to kill some time on the occasional rainy day. But if your collection leaves a lot to be desired, you can class-up your selection with this great deal on the Vintage Bookshelf Edition of Clue for $40.

A brief history of Clue

'Clue' Vintage Bookshelf Edition.
WS Game Company.

Originally titled Murder!, Clue was created by a musician named Anthony Pratt in Birmingham, England, in 1943, and he filed a patent for it in 1944. He sold the game to Waddington's in the UK a few years later, and they changed the name to Cluedo in 1949 (that name was a mix between the words clue and Ludo, which was a 19th-century game.) That same year, the game was licensed to Parker Brothers in the United States, where it was published as Clue. Since then, there have been numerous special editions and spinoffs of the original game, not to mention books and a television series based on it. Most notably, though, was the cult classic 1985 film Clue, which featured Eileen Brennan, Tim Curry, Madeline Kahn, Christopher Lloyd, Michael McKean, Martin Mull, and Lesley Ann Warren.

As you probably know, every game of Clue begins with the revelation of a murder. The object of the game is to be the first person to deduce who did it, with what weapon, and where. To achieve that end, each player assumes the role of one of the suspects and moves strategically around the board collecting clues.

With its emphasis on logic and critical thinking—in addition to some old-fashioned luck—Clue is a masterpiece that has stood the test of time and evolved with each decade, with special versions of the game hitting shelves recently based on The Office, Rick and Morty, and Star Wars.

Tear Gas vs. Pepper Spray: What’s the Difference?

Pepper spray and tear gas are both non-lethal irritants that cause extreme burning of the eyes, nose, and throat—but there are a few key differences between the two substances.

For one, they’re created from different chemicals. According to biohazard remediation company Aftermath, the active ingredient in pepper spray is oleoresin capsicum, which comes from the compound that makes hot peppers so hot: capsaicin. If you’ve ever accidentally rubbed your eyes after chopping a chili pepper, you’ve gotten a very tiny taste of what it’s like to be sprayed with pepper spray. Tear gas, on the other hand, contains 0-Chlorobenzylidenemalononitrile (CS), 2-chlorobenzalmalononitrile (CN), or a similar artificial chemical. At room temperature, both of those chemicals are powdery solids, not gases—they’re mixed with liquids or gases so they can be dispersed in the air.

Delivery methods differ, too. Pepper spray often comes in an aerosol can, which shoots it in a stream, a mist, or some other relatively direct path (though it’s also available as a gel or foam). As the Berkeley Science Review explains, tear gas is mainly dispersed with a grenade, which releases the substance over a wide area when it explodes. Since the grenades can cover so much ground, law enforcement officers are more likely to use tear gas to try to break up a crowd, and civilians are more likely to carry pepper spray as a personal safety measure.

The immediate effects of the two substances are similar—burning sensation in mucous membranes, rise in blood pressure, difficulty breathing, runny nose, etc.—but tear gas can also cause nausea and vomiting in higher concentrations.
