Common sense dictates that since light-colored clothing is more reflective than dark, it'll help keep you cooler in hot weather. Learn why this myth doesn't hold water in today's episode of BrainStuff, based on this article: https://science.howstuffworks.com/science-vs-myth/everyday-myths/light-colored-clothes-in-hot-weather.htm

Welcome to brain Stuff, a production of iHeart Radio. Hey
brain Stuff, Lauren A bogle Bomb here. Question, what all
do astronauts, modernly traditional brides, American author Tom Wolf, and
some people trying to keep cool in hot weather have
in common? Answer? They all wear white, and that's probably
(00:26):
what all they have in common, but you never know anyway.
The sartorial thinking is this, fabrics of the lightest colors
force all the solar heat fighting its way to our
skin to just reflect away instead, where dark fabrics, the
idea goes, and you're stuck with that heat. Is it
greedily absorbs into the fabric and causes you to swelter
(00:48):
in your own clothes. But white clothing will cheerfully bounce
that solar heat right off, and you'll be more comfortable
on a hot day. But while all that certainly sounds
great in theory, there are a few other factors at
play that might be working against the light clothing adage.
At the very least, there is some compelling evidence in
(01:10):
the form of a real, true scientific study that says
it doesn't matter. Let's start with some research published in
night in the journal Nature titled why the Bedouins wear
black robes and hot deserts. The researchers were curious about
the fact that in oppressive heat, the residents of the
Sinai Desert wear billowing black robes instead of say white
(01:34):
or maybe a pretty pale lavender. What they found was
when they tested white robes versus black, and note that
they did this by having some poor guy stand out
in the heat while recording temperature, the differences were nil.
They found that the black clothing did more to absorb heat,
but that's where it stayed. In other words, the black
(01:56):
soaks up additional heat, but that extra is law by
the time it actually gets to your skin. A way
more useful for keeping cool, however, was the fact that
the robes are loose and billowing to allow air flow.
There's also a concept that the whole light clothing argument
is missing a key element the person who's wearing the clothes,
(02:19):
meaning that the heat your body radiates will reflect off
of white clothing as readily as heat from the sun does,
bouncing back to your body and actually keeping you toastier.
Not a bad theory, but it's not been tested on humans.
It's only been studied in birds with white plumage, and
that with mixed results. So the answer is it doesn't
(02:42):
make a huge difference whether you're wearing black or white
in hot weather as long as you choose loose, breathable
clothing either way. Today's episode is based on the article
should you wear light colored clothes and hot weather to
stay cool? On how stuff works dot com written by

The Burden
The Burden is a documentary series that takes listeners into the hidden places where justice is done (and undone). It dives deep into the lives of heroes and villains. And it focuses a spotlight on those who triumph even when the odds are against them. Season 5 - The Burden: Death & Deceit in Alliance On April Fools Day 1999, 26-year-old Yvonne Layne was found murdered in her Alliance, Ohio home. David Thorne, her ex-boyfriend and father of one of her children, was instantly a suspect. Another young man admitted to the murder, and David breathed a sigh of relief, until the confessed murderer fingered David; “He paid me to do it.” David was sentenced to life without parole. Two decades later, Pulitzer winner and podcast host, Maggie Freleng (Bone Valley Season 3: Graves County, Wrongful Conviction, Suave) launched a “live” investigation into David's conviction alongside Jason Baldwin (himself wrongfully convicted as a member of the West Memphis Three). Maggie had come to believe that the entire investigation of David was botched by the tiny local police department, or worse, covered up the real killer. Was Maggie correct? Was David’s claim of innocence credible? In Death and Deceit in Alliance, Maggie recounts the case that launched her career, and ultimately, “broke” her.” The results will shock the listener and reduce Maggie to tears and self-doubt. This is not your typical wrongful conviction story. In fact, it turns the genre on its head. It asks the question: What if our champions are foolish? Season 4 - The Burden: Get the Money and Run “Trying to murder my father, this was the thing that put me on the path.” That’s Joe Loya and that path was bank robbery. Bank, bank, bank, bank, bank. In season 4 of The Burden: Get the Money and Run, we hear from Joe who was once the most prolific bank robber in Southern California, and beyond. He used disguises, body doubles, proxies. He leaped over counters, grabbed the money and ran. Even as the FBI was closing in. It was a showdown between a daring bank robber, and a patient FBI agent. Joe was no ordinary bank robber. He was bright, articulate, charismatic, and driven by a dark rage that he summoned up at will. In seven episodes, Joe tells all: the what, the how… and the why. Including why he tried to murder his father. Season 3 - The Burden: Avenger Miriam Lewin is one of Argentina’s leading journalists today. At 19 years old, she was kidnapped off the streets of Buenos Aires for her political activism and thrown into a concentration camp. Thousands of her fellow inmates were executed, tossed alive from a cargo plane into the ocean. Miriam, along with a handful of others, will survive the camp. Then as a journalist, she will wage a decades long campaign to bring her tormentors to justice. Avenger is about one woman’s triumphant battle against unbelievable odds to survive torture, claim justice for the crimes done against her and others like her, and change the future of her country. Season 2 - The Burden: Empire on Blood Empire on Blood is set in the Bronx, NY, in the early 90s, when two young drug dealers ruled an intersection known as “The Corner on Blood.” The boss, Calvin Buari, lived large. He and a protege swore they would build an empire on blood. Then the relationship frayed and the protege accused Calvin of a double homicide which he claimed he didn’t do. But did he? Award-winning journalist Steve Fishman spent seven years to answer that question. This is the story of one man’s last chance to overturn his life sentence. He may prevail, but someone’s gotta pay. The Burden: Empire on Blood is the director’s cut of the true crime classic which reached #1 on the charts when it was first released half a dozen years ago. Season 1 - The Burden In the 1990s, Detective Louis N. Scarcella was legendary. In a city overrun by violent crime, he cracked the toughest cases and put away the worst criminals. “The Hulk” was his nickname. Then the story changed. Scarcella ran into a group of convicted murderers who all say they are innocent. They turned themselves into jailhouse-lawyers and in prison founded a lway firm. When they realized Scarcella helped put many of them away, they set their sights on taking him down. And with the help of a NY Times reporter they have a chance. For years, Scarcella insisted he did nothing wrong. But that’s all he’d say. Until we tracked Scarcella to a sauna in a Russian bathhouse, where he started to talk..and talk and talk. “The guilty have gone free,” he whispered. And then agreed to take us into the belly of the beast. Welcome to The Burden.
