Chorus or Cacophony? Cicada Song Hits Some Ears Harder Than Others

ST. LOUIS — Shhhooo. Wee-uuu. Chick, chick, chick. That’s the sound of three different cicada species. For some people, those sounds are the song of the summer. Others wish the insects would turn it down. The cacophony can be especially irritating for people on the autism spectrum who have hearing sensitivity.

Warren Rickly, 14, lives in suburban south St. Louis County, Missouri. Warren, who has autism, was at the bus stop recently waiting for his younger brother when the sound of cicadas became too much to bear.

“He said it sounds like there’s always a train running next to him,” his mother, Jamie Reed, said.

Warren told her the noise hurt.

Starting this spring, trillions of the red-eyed insects crawled their way out of the ground across the Midwest and Southeast. It’s part of a rare simultaneous emergence of two broods — one that appears every 13 years, the other every 17.

The noisy insects can be stressful. People with autism can have a sensitivity to texture, brightness, and sound.

“I think the difference for individuals with autism is the level of intensity or how upsetting some of these sensory differences are,” said Rachel Follmer, a developmental and behavioral pediatrician at Lurie Children’s Hospital in Chicago.

“It can get to the extreme where it can cause physical discomfort,” she said.

When a large group of cicadas starts to sing, the chorus can be as loud as a motorcycle. Researchers at the University of Missouri-St. Louis this year crowdsourced cicada noise levels as high as 86 decibels, about as loud as a food blender.

That can be stressful, not melodic, Follmer said.

To help children cope, she suggests giving them a primer before they encounter a noisy situation. For cicadas, that could mean explaining what they are, that they don’t bite or sting, and that they’ll be here for just a short time.

“When something is uncomfortable, not having power in that situation can be very scary for a lot of individuals, whether you’re on the spectrum or not,” Follmer said.

Jamie Reed’s family has been using this and other strategies to help her son. Warren wears noise-canceling headphones, listens to music, and has been teaching himself about cicadas.

“For him, researching it and looking into it I think grounds him a little bit,” Reed said.

Fatima Husain is a professor and neuroscientist at the University of Illinois Urbana-Champaign and studies how the brain processes sound. She said people with tinnitus may also struggle with cicada song.

Tinnitus, a ringing or other noise in the ears, is a person’s perception of sound without an external source.

“Some people say it sounds like buzzing, like wind blowing through trees, and ironically, quite a few people say it sounds like cicadas,” Husain said.

For most people with tinnitus the cicada’s song is harmless background noise, according to Husain, but for others the ringing can prevent easy conversation or sleep. Those with tinnitus are also more likely to have anxiety or depression. A loud persistent sound, like singing cicadas, can make someone’s tinnitus worse, Husain said.

It’s not always bad, though. The cicada’s song can also be a relief.

For some, tinnitus gets worse in a quiet environment. Husain said she’s seen reports this year of patients saying the cicadas’ song has been like soothing white noise.

“The sound is loud enough that in some ways it’s drowning their internal tinnitus,” Husain said.

As loud as the cicadas can be, they won’t necessarily damage anyone’s hearing, according to the Centers for Disease Control and Prevention. Hearing loss builds up over time from repeated exposure to loud sounds. Cicadas aren’t loud enough for long enough to do lasting damage, Husain said.

Everyday sources of noise come with a higher risk. Husain said constant exposure to loud highways, an airport, industrial sites, or household appliances like blenders and hair dryers can be a concern. And they can take a toll on someone’s emotional well-being.

“If you are being exposed to very loud sounds for a part of your school day or your working day, it may make you more stressed out; it may make you more angry about things,” she said.

Unlike the highway or an airport, cicadas won’t be around long. Most of the current brood will be gone in the next few weeks. Just in time for another noisy summer event: the Fourth of July.

  • The Checklist Manifesto – by Dr. Atul Gawande

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Dr. Gawande, himself a general surgeon, uses checklists a lot. He is, unequivocally, an expert in his field. He “shouldn’t” need a checklist to tell him to do such things as “Check you have the correct patient”. But checklists are there as a safety net. And, famously, “safety regulations are written in blood”, after all.

    And, who amongst us has never made such a “silly” error? From forgetting to turn the oven on, to forgetting to take the handbrake off, it takes only a momentary distraction to think we’ve done something we haven’t.

    You may be wondering: why a whole book on this? Is it just many examples of the usefulness of checklists? Because I’m already sold on that, so, what else am I going to get out of it?

    Dr. Gawande also explains in clear terms:

    • How to optimize “all necessary steps” with “as few steps as possible”
    • The important difference between read-do checklists and do-confirm checklists
    • To what extent we should try to account for the unexpected
    • How to improve compliance (i.e., making sure you actually use it, no matter how tempting it will be to go “yeah this is automatic for me now” and gloss over it)
    • The role of checklists in teams, and in passing on knowledge

    …and more.

    Bottom line: if you’ve ever tried to make tea without putting the tea-leaves in the pot, this is the book that will help you avoid making more costly mistakes—whatever your area of activity or interest.

  • Luxurious Longevity Risotto

    Pearl barley is not only tasty and fiber-rich, but also, it contains propionic acid, which lowers cholesterol. The fiber content also lowers cholesterol too, of course, by the usual mechanism. The dish’s health benefits don’t end there, though; check out the science section at the end of the recipe!

    You will need

    • 2 cups pearl barley
    • 3 cups sliced chestnut mushrooms
    • 2 onions, finely chopped
    • 6 large leaves collard greens, shredded
    • ½ bulb garlic, finely chopped
    • 8 spring onions, sliced
    • 1½ quarts low-sodium vegetable stock
    • 2 tbsp nutritional yeast
    • 1 tbsp chia seeds
    • 1 tbsp black pepper, coarse ground
    • 1 tsp MSG or 2 tsp low-sodium salt
    • 1 tsp rosemary
    • 1 tsp thyme
    • Extra virgin olive oil, for cooking
    • Optional garnish: fresh basil leaves

    Method

    (we suggest you read everything at least once before doing anything)

    1) Heat a little oil in a large sauté pan; add the onions and garlic and cook for 5 minutes; add the mushrooms and cook for another 5 minutes.

    2) Add the pearl barley and a cup of the vegetable stock. Cook, stirring, until the liquid is nearly all absorbed, and add more stock every few minutes, as per any other risotto. You may or may not use all the stock you had ready. Pearl barley takes longer to cook than rice, so be patient—it’ll be worth the wait!

    Alternative: an alternative is to use a slow cooker, adding a quart of the stock at once and coming back about 4 hours later—thus, it’ll take a lot longer, but will require minimal/no supervision.

    3) When the pearl barley has softened, become pearl-like, and the dish is taking on a creamy texture, stir in the rest of the ingredients. Once the greens have softened, the dish is done, and it’s time to serve. Add the garnish if using one:

    Enjoy!

  • Why is cancer called cancer? We need to go back to Greco-Roman times for the answer

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    One of the earliest descriptions of someone with cancer comes from the fourth century BC. Satyrus, tyrant of the city of Heracleia on the Black Sea, developed a cancer between his groin and scrotum. As the cancer spread, Satyrus had ever greater pains. He was unable to sleep and had convulsions.

    Advanced cancers in that part of the body were regarded as inoperable, and there were no drugs strong enough to alleviate the agony. So doctors could do nothing. Eventually, the cancer took Satyrus’ life at the age of 65.

    Cancer was already well known in this period. A text written in the late fifth or early fourth century BC, called Diseases of Women, described how breast cancer develops:

    hard growths form […] out of them hidden cancers develop […] pains shoot up from the patients’ breasts to their throats, and around their shoulder blades […] such patients become thin through their whole body […] breathing decreases, the sense of smell is lost […]

    Other medical works of this period describe different sorts of cancers. A woman from the Greek city of Abdera died from a cancer of the chest; a man with throat cancer survived after his doctor burned away the tumour.

    Where does the word ‘cancer’ come from?

    Galen, the physician
    Why does the word ‘cancer’ have its roots in the ancient Greek and Latin words for crab? The physician Galen offers one explanation. Pierre Roche Vigneron/Wikimedia

    The word cancer comes from the same era. In the late fifth and early fourth century BC, doctors were using the word karkinos – the ancient Greek word for crab – to describe malignant tumours. Later, when Latin-speaking doctors described the same disease, they used the Latin word for crab: cancer. So, the name stuck.

    Even in ancient times, people wondered why doctors named the disease after an animal. One explanation was the crab is an aggressive animal, just as cancer can be an aggressive disease; another explanation was the crab can grip one part of a person’s body with its claws and be difficult to remove, just as cancer can be difficult to remove once it has developed. Others thought it was because of the appearance of the tumour.

    The physician Galen (129-216 AD) described breast cancer in his work A Method of Medicine to Glaucon, and compared the form of the tumour to the form of a crab:

    We have often seen in the breasts a tumour exactly like a crab. Just as that animal has feet on either side of its body, so too in this disease the veins of the unnatural swelling are stretched out on either side, creating a form similar to a crab.

    Not everyone agreed what caused cancer

    In the Greco-Roman period, there were different opinions about the cause of cancer.

    According to a widespread ancient medical theory, the body has four humours: blood, yellow bile, phlegm and black bile. These four humours need to be kept in a state of balance, otherwise a person becomes sick. If a person suffered from an excess of black bile, it was thought this would eventually lead to cancer.

    The physician Erasistratus, who lived from around 315 to 240 BC, disagreed. However, so far as we know, he did not offer an alternative explanation.

    How was cancer treated?

    Cancer was treated in a range of different ways. It was thought that cancers in their early stages could be cured using medications.

    These included drugs derived from plants (such as cucumber, narcissus bulb, castor bean, bitter vetch, cabbage); animals (such as the ash of a crab); and metals (such as arsenic).

    Galen claimed that by using this sort of medication, and repeatedly purging his patients with emetics or enemas, he was sometimes successful at making emerging cancers disappear. He said the same treatment sometimes prevented more advanced cancers from continuing to grow. However, he also said surgery is necessary if these medications do not work.

    Surgery was usually avoided as patients tended to die from blood loss. The most successful operations were on cancers of the tip of the breast. Leonidas, a physician who lived in the second and third century AD, described his method, which involved cauterising (burning):

    I usually operate in cases where the tumours do not extend into the chest […] When the patient has been placed on her back, I incise the healthy area of the breast above the tumour and then cauterize the incision until scabs form and the bleeding is stanched. Then I incise again, marking out the area as I cut deeply into the breast, and again I cauterize. I do this [incising and cauterizing] quite often […] This way the bleeding is not dangerous. After the excision is complete I again cauterize the entire area until it is dessicated.

    Cancer was generally regarded as an incurable disease, and so it was feared. Some people with cancer, such as the poet Silius Italicus (26-102 AD), died by suicide to end the torment.

    Patients would also pray to the gods for hope of a cure. An example of this is Innocentia, an aristocratic lady who lived in Carthage (in modern-day Tunisia) in the fifth century AD. She told her doctor divine intervention had cured her breast cancer, though her doctor did not believe her.

    From the past into the future

    We began with Satyrus, a tyrant in the fourth century BC. In the 2,400 years or so since then, much has changed in our knowledge of what causes cancer, how to prevent it and how to treat it. We also know there are more than 200 different types of cancer. Some people’s cancers are so successfully managed, they go on to live long lives.

    But there is still no general “cure for cancer”, a disease that about one in five people develop in their lifetime. In 2022 alone, there were about 20 million new cancer cases and 9.7 million cancer deaths globally. We clearly have a long way to go.

  • The Collagen Cure – by Dr. James DiNicolantonio

    Collagen is vital for, well, most of our bodies, really. Where me most tend to feel its deficiency is in our joints and skin, but it’s critical for bones and many other tissues too.

    You may be wondering: why a 572-page book to say what surely must amount to “take collagen, duh”?

    Dr. DiNicolantonio has a lot more of value to offer us than that. In this book, we learn about not just collagen synthesis and usage, different types of collagen, the metabolism of it in our diet (if we get it—vegans and vegetarians won’t). We also learn about the building blocks of collagen (vegans and vegetarians do get these, assuming a healthy balanced diet), with a special focus on glycine, the smallest amino acid which makes up about a third of the mass of collagen (a protein).

    Not stopping there, we also learn about the interplay of other nutrients with our metabolism of glycine and, if applicable, collagen. Vitamin C and copper are star features, but there’s a lot more going on with other nutrients too, down to the level of “So take this 75 minutes before this but after that and/but definitely not with the other”, etc.

    The style is incredibly clear and readable for something that’s also quite scientifically dense (over 1000 references and many diagrams).

    Bottom line: if you’re serious about maintaining your body as you get older, and you’d like a book about collagen that’s a lot more helpful than “take collagen, duh”, then this is the book for you.

  • Polyphenol Paprika Pepper Penne

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    This one’s easier to promptly prepare than it is to pronounce unprepared! Ok, enough alliteration: this dish is as full of flavor as it is full of antioxidants, and it’s great for digestive health and heart health too.

    You will need

    • 4 large red bell peppers, diced
    • 2 red onions, roughly chopped
    • 1 bulb garlic, finely chopped
    • 2 cups cherry tomatoes, halved
    • 10oz wholemeal penne pasta
    • 1 tbsp nutritional yeast
    • 1 tbsp smoked paprika
    • 1 tbsp black pepper
    • Extra virgin olive oil for drizzling

    Method

    (we suggest you read everything at least once before doing anything)

    1) Preheat the oven to 200℃ / 400℉ / Gas mark 6

    2) Put the vegetables in a roasting tin; drizzle with oil, sprinkle with the seasonings (nooch, paprika, black pepper), stir well to mix and distribute the seasonings evenly, and roast for 20–25 minutes, stirring/turning occasionally. When the edges begin to caramelize, turn off the heat, but leave to keep warm.

    3) Cook the penne al dente (this should take 7–8 minutes in boiling salted water). Rinse in cold water, then pass a kettle of hot water over them to reheat. This process removed starch and lowered the glycemic index, before reheating the pasta so that it’s hot to serve.

    4) Place the roasted vegetables in a food processor and blitz for just a few seconds. You want to produce a very chunky sauce—but not just chunks or just sauce.

    5) Combine the sauce and pasta to serve immediately.

    Enjoy!

  • Is cold water bad for you? The facts behind 5 water myths

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    We know the importance of staying hydrated, especially in hot weather. But even for something as simple as a drink of water, conflicting advice and urban myths abound.

    Is cold water really bad for your health? What about hot water from the tap? And what is “raw water”? Let’s dive in and find out.

    Myth 1: Cold water is bad for you

    Some recent TikToks have suggested cold water causes health problems by somehow “contracting blood vessels” and “restricting digestion”. There is little evidence for this.

    While a 2001 study found 51 out of 669 women tested (7.6%) got a headache after drinking cold water, most of them already suffered from migraines and the work hasn’t been repeated since.

    Cold drinks were shown to cause discomfort in people with achalasia (a rare swallowing disorder) in 2012 but the study only had 12 participants.

    For most people, the temperature you drink your water is down to personal preference and circumstances. Cold water after exercise in summer or hot water to relax in winter won’t make any difference to your overall health.

    Myth 2: You shouldn’t drink hot tap water

    This belief has a grain of scientific truth behind it. Hot water is generally a better solvent than cold water, so may dissolve metals and minerals from pipes better. Hot water is also often stored in tanks and may be heated and cooled many times. Bacteria and other disease-causing microorganisms tend to grow better in warm water and can build up over time.

    It’s better to fill your cup from the cold tap and get hot water for drinks from the kettle.

    Myth 3: Bottled water is better

    While bottled water might be safer in certain parts of the world due to pollution of source water, there is no real advantage to drinking bottled water in Australia and similar countries.

    According to University of Queensland researchers, bottled water is not safer than tap water. It may even be tap water. Most people can’t tell the difference either. Bottled water usually costs (substantially) more than turning on the tap and is worse for the environment.

    What about lead in tap water? This problem hit the headlines after a public health emergency in Flint, Michigan, in the United States. But Flint used lead pipes with a corrosion inhibitor (in this case orthophosphate) to keep lead from dissolving. Then the city switched water sources to one without a corrosion inhibitor. Lead levels rose and a public emergency was declared.

    Fortunately, lead pipes haven’t been used in Australia since the 1930s. While lead might be present in some old plumbing products, it is unlikely to cause problems.

    Myth 4: Raw water is naturally healthier

    Some people bypass bottled and tap water, going straight to the source.

    The “raw water” trend emerged a few years ago, encouraging people to drink from rivers, streams and lakes. There is even a website to help you find a local source.

    Supporters say our ancestors drank spring water, so we should, too. However, our ancestors also often died from dysentery and cholera and their life expectancy was low.

    While it is true even highly treated drinking water can contain low levels of things like microplastics, unless you live somewhere very remote, the risks of drinking untreated water are far higher as it is more likely to contain pollutants from the surrounding area.

    Myth 5: It’s OK to drink directly from hoses

    Tempting as it may be, it’s probably best not to drink from the hose when watering the plants. Water might have sat in there, in the warm sun for weeks or more potentially leading to bacterial buildup.

    Similarly, while drinking water fountains are generally perfectly safe to use, they can contain a variety of bacteria. It’s useful (though not essential) to run them for a few seconds before you start to drink so as to get fresh water through the system rather than what might have been sat there for a while.

    We are fortunate to be able to take safe drinking water for granted. Billions of people around the world are not so lucky.

    So whether you like it hot or cold, or somewhere in between, feel free to enjoy a glass of water this summer.

    Just don’t drink it from the hose.The Conversation
