WTF Fun Fact 13257 – Snoring and Relationships

Snoring is bad for relationships. The damage is hard to quantify since there are many reasons for poor sleep, and a lack of sleep can lead to everything from health issues to resentment. But it seems clear that if one person snores and keeps the other awake, it frequently leads to trouble. Snoring and relationships are a terrible combination.

Why snoring is bad for relationships

There are many incorrect statistics out there (like snoring is the third leading cause of divorce – it’s not) due to people misreading scientific research. But plenty of work has been done on the damage one partner’s snoring can do to the other and the relationship overall.

For example, the Sleep Disorders Center at Rush University Medical Center conducted a study on couples in which the husband had sleep apnea that affected the wife’s ability to sleep due to snoring. They found cases in which the wife’s sleep efficiency scores decreased significantly because they were woken up by snoring up to 8 times per hour!

Rosalind Cartwright, Ph.D., founder of the Sleep Disorders Center at Rush, noted:

“Couples who struggle with sleep apnea have a high divorce rate. Our early results are showing that the wife’s sleep is indeed deprived due to the husband’s noisy nights. This is not a mild problem. The lack of sleep for both partners puts a strain on the marriage and creates a hostile and tense situation.”

The good news is that when the sleep apnea was treated, and the snoring ceased to disturb the wife’s sleep, her quality of life went up, her sleepiness went down, and the marital satisfaction score improved.

It’s important to note that while studies suggest a link between snoring and marital conflict, they do not necessarily imply causation. Snoring may be a symptom of an underlying health condition (such as sleep apnea). It’s possible that these factors, rather than the snoring itself, may be contributing to conflict. And, of course, studies may not apply to all couples.

More research is needed to fully understand the relationship between snoring and marital conflict.

The “sleep divorce”

A sleep divorce is a term that refers to the practice of couples sleeping separately to get a better night’s sleep. It can mean sleeping in different beds or different rooms.

This practice is becoming increasingly popular among couples. Some find that snoring, tossing and turning, or different sleep schedules destroy a partner’s sleep. This can lead to a variety of health problems.

There are many reasons why couples may choose to sleep separately. Snoring is among the most common since it can happen frequently and lead to daytime fatigue and irritability.

While the idea of sleeping separately may seem unromantic to some, it can actually have several benefits. Sleeping separately can lead to better sleep quality, improving mood, productivity, and overall health. It can also reduce arguments and conflicts that may arise from sleep disturbances. This can improve the overall quality of the relationship.

Of course, for some, sharing a bed may be an important part of the intimacy and connection in their relationship. Additionally, it’s important for couples to communicate openly about their sleeping arrangements and work together to find a solution that works for both partners.

WTF Fun Fact 13250 – Posting Uninformed Comments

We all know that the comment section is a black hole that attracts uninformed comments. It’s the place where dignity and informed debate go to die. But a 2019 study by researchers at York College of Pennsylvania gives some insight into why these comments are so prevalent.

However, the authors distinguish between being uninformed (recognizing one’s own ignorance) and misinformed (confidently holding inaccurate beliefs). In this case, we’re talking mainly about misinformation. But not all researchers use these words in the same way.

Why are there so many uninformed comments and misinformed commenters?

In a nutshell, it’s because people just don’t read enough. If they do, they skim previews of most content. This is especially true when it’s about something that riles them up – like politics. They don’t take the time to really try and process what an article is about before they comment on it. In fact, skimming makes them highly confident that they do have something worthwhile to say. Never mind that this is correlated with having less reliable insight.

According to ScienceAlert’s coverage of the research (cited below):

“By glancing through article previews, instead of reading the full piece, many users overestimate their understanding of an issue, and this is especially true for those whose knowledge is guided by strong emotions – and, therefore, strong opinions.”

The research on uninformed comments comes from the academic article “A little bit of knowledge: Facebook’s News Feed and self-perceptions of knowledge” published in the journal Research & Politics.

There, the authors note:

“We argue that Facebook’s News Feed itself, with its short article previews, provides enough political information for learning to occur. However, this learning comes with an additional consequence: audiences who only read article previews think they know more than they actually do, especially individuals who are motivated to seek emotions.”

Emotions over data

You’ve probably noticed that people with strong opinions like to throw out information they seem confident about. But it’s worth considering how much it matches their desire to seem smart.

The researchers noted, “Those who are more driven by emotion allow the positive feelings associated with being right to override the need for actual accuracy, thus coming away from limited exposure to information falsely overconfident in their knowledge of the subject matter.”

WTF Fun Fact 13247 – The Fish with a Unicorn Horn

Scientists in China have discovered a new species of fish with a unicorn horn. Named “Sinocyclocheilus longicornus,” the lives in pitch-black caves, has no scales, tiny eyes that are likely non-functional, and a unicorn-like horn sticking out of its head.

What’s the story behind the fish with the unicorn horn?

Scientists discovered the fish in a remote cave system in Guizhou Province in southwestern China. The discovery was made by a team of scientists led by Dr. Meng Wu of the Chinese Academy of Sciences, who specialize in studying subterranean life forms.

Sinocyclocheilus longicornus is a type of cave fish, which means it has adapted to living in a dark, aquatic environment without any access to sunlight. Like other cave fish, Sinocyclocheilus longicornus has evolved certain physical traits to help it survive in this challenging habitat. For example, it lacks developed eyes and pigmentation, since these features are not necessary in a pitch-black cave.

However, it’s the “unicorn horn” made of bony tissue that’s stirring up curiosity. Scientists believe the fish use the horn for fighting or as a way to sense their environment.

Why is this discovery important?

The discovery of Sinocyclocheilus longicornus is just one example of the ongoing research into subterranean life forms and the unique adaptations that allow them to thrive in the dark, hidden corners of the world. As scientists continue to study these organisms, we may gain new insights into the evolution of life on Earth and the incredible resilience of living things in the face of extreme environmental conditions.

Furthermore, the discovery of a new species of cave fish is particularly exciting for scientists. It highlights how much we still have to discover about life on Earth. Despite centuries of exploration and research, there are still many corners of the planet that remain largely unexplored. This is particularly true of the deep, dark recesses of the world’s caves and other subterranean environments.

Finally, the discovery of Sinocyclocheilus longicornus serves as a reminder of the importance of protecting these unique and fragile ecosystems. Caves and other subterranean environments are home to a wealth of unique species that are found nowhere else on Earth. Mining, tourism, and other human activities can disrupt the delicate balance of these ecosystems. The result is irreparable harm to the species that live there. — WTF fun facts

WTF Fun Fact 13246 – The Mathematical Roots of the Jungle Gym

A Princeton University mathematician named Sebastian Hinton invented the jungle gym (and monkey bars). He patented them as the “jungle gym” in 1920. Hinton designed the apparatus as a way to help children develop physical coordination and endurance – and to understand theoretical geometry.

What’s the history behind the jungle gym?

According to Smithsonian Magazine (cited below): Hinton “built a cubic bamboo grid in the family’s backyard to teach [his children] to visualize space in three dimensions as they moved through the structure. But the kids were more drawn to climbing and swinging on the bars.”

Cimbing is a near-universal juvenile activity in humans and other primates. However, the safety of jungle gyms and monkey bars has come into question. Still, child psychologists insist that “risky play” is essential on some level for healthy development.

Hinton’s patent document describes a “climbing structure.” It consists of a series of metal bars arranged in a vertical or diagonal configuration supported by a frame. The bars are spaced apart at a distance requiring the user to stretch and grasp the next bar to continue.

The document includes detailed illustrations and specifications for the construction and installation of the climbing structure.

Playground mathematics

Hinton’s math background played a complex role in the creation of the equipment.

Living in Japan at the time, Hinton built the bamboo framework in his backyard for his children. One of his goals was to get kids moving in three-dimensional space. Without this experience, he didn’t think humans could properly grasp the mathematical concept of a fourth dimension. The fourth dimension can be used to help explain the geometry and topology of three-dimensional objects.

For example, a jungle gym can be thought of as a set of interconnected vertices, edges, and faces that define its shape and structure. This idea is related to the concept of a “graph” in mathematics, which is a set of vertices that are connected by edges.

In some cases, the topology of a three-dimensional object can also be related to a four-dimensional object. For example, a hypercube or tesseract is an extension of the three-dimensional cube into a fourth dimension.

While this is a highly abstract concept, Hinton designed the jungle gym/monkey bars with this in mind.

WTF Fun Fact 13239 – Indoor Air is More Polluted

More and more people are worried about air quality. But hiding indoors doesn’t appear to be an option for some people if their indoor air is more polluted. And that appears to be the case for a lot of people.

How can you know if your indoor air is more polluted than outdoors?

You can typically get readings for outdoor air quality with the weather report these days. Air pollution can come from natural sources like pollen or unnatural sources like factories, cars, and other machinery.

Testing your indoor air is another matter. But there are a few ways to get a clue about your indoor air quality. For example, if you experience frequent allergies or asthma indoors, you may have compromised air quality. If you can see or smell mold, mildew, or chemicals from cleaning supplies, your air is compromised.

If you walk into your home and experience irritation of the nose, eyes, or throat, experience skin rashes even when staying home for extended periods, or tend to experience dry skin, unexplained coughing, fatigue, dizziness, or headaches, it may be time to check your indoor air quality. (Of course, these can be symptoms of other issues as well.)

Sources of “bad air”

Indoor air pollution can come from some unlikely places. Obviously, bad air can seep into your home from outside or be tracked in on your clothing, hands, or shoes.

Other sources of indoor air pollution are:

  • Consumer products (like TVs, furniture, or things made of plastic) that tend to emit the chemicals Polybrominated biphenyl (PBB) or Polychlorinated biphenyl (PCB).
  • Wood cleaners or sealants and mattresses that contain polyurethane.
  • Carpeting, plywood, and upholstery that can emit formaldehyde.
  • Cigarette smoke.
  • Mold and mildew growing in damp areas of your home.
  • Scent diffusers and candles.
  • Pesticide residue or pollen from your shoes.
  • Dust mites and roach droppings.
  • Fireplaces that emit combustion byproducts such as carbon monoxide.
  • Pets (And there is no such thing as a hypoallergenic, dander-free pet!)

The list goes on, but these are major sources that can sometimes be remediated with air purifiers. If your house has poor ventilation, you may feel the effects of indoor air pollutants more acutely.

Getting rid of your floors and furniture certainly isn’t an option for most people. However, you can prohibit smoking indoors and cut down on your use of chemical cleaners. This is especially important if someone in your home has asthma or allergies. — WTF fun facts

WTF Fun Fact 13236 – Health Benefits of Holding Hands

Studies have shown the health benefits of holding hands with someone you love. This can reduce stress and anxiety. That’s because the physical act of holding hands releases oxytocin, a hormone associated with feelings of love, trust, and comfort.

The other health benefits of holding hands

In addition, holding hands with someone you love can also lower blood pressure and reduce physical pain, making it an effective way to promote overall well-being and improve mental and physical health.

Holding hands can also boost self-esteem and confidence, making it a helpful tool for managing feelings of insecurity or low self-worth. It can even encourage communication, which helps to facilitate deeper connections and understanding between individuals.

Studies have also shown that holding hands can help to improve memory recall and enhance cognitive function.

Oxytocin: The “love drug”

Oxytocin is often referred to as the “love hormone” for its positive effects on physical and mental health. For example, studies have shown that the release of oxytocin can help to lower blood pressure. This, in turn, can reduce the risk of cardiovascular disease and stroke.

It can also have pain-relieving effects that can help treat a variety of painful conditions like migraines, menstrual cramps, and arthritis.

The “love hormone” is also a mood booster. Oxytocin can reduce symptoms of depression and anxiety in some people.

Finally, doing things that release oxytocin can help you strengthen your relationships. It helps promote feelings of love, trust, and comfort. This helps you form both personal and social bonds with those around you.

Reach out and touch…

There are many studies that demonstrate the cognitive benefits of touch. Yet it’s a sense that we don’t fully appreciate. Nevertheless, it helps us form both bonds and memories.

So, next time you’re feeling stressed or anxious, try reaching for your loved one’s hand. — WTF fun facts

WTF Fun Fact 13235 – Pacemaker Recycling

All kinds of people from all walks of life can develop heart disease and need a pacemaker. But not everyone can afford them. That’s why pacemaker recycling projects are popping up around the country to ensure that people of all incomes can have access to this life-saving technology. As a bonus, they also help the environment.

What’s the point of pacemaker recycling?

The main goal of pacemaker recycling is to reduce waste and conserve natural resources, as well as to provide access to medical devices for individuals who may not otherwise have access to them.

Pacemakers are small, implantable devices that are used to regulate the heartbeat of people with heart conditions. They are typically made from a combination of metal and plastic components and can be expensive to produce.

When a pacemaker is no longer needed, it can be difficult to dispose of properly. That’s because the materials used to make the device are not biodegradable and can pose environmental and health risks.

Pacemaker recycling helps to mitigate these risks by collecting used pacemakers and other medical devices. Then, they’re refurbished for reuse or broken down into their component parts for recycling. This reduces waste and conserves natural resources. It also provides access to medical devices for individuals who may not otherwise have access to them.

Do people use these recycled items?

Yes, absolutely. And they’re life-saving.

In many developing countries, access to medical devices, including pacemakers, can be limited due to high costs and a lack of infrastructure. Pacemaker recycling programs can help to address these challenges by providing refurbished medical devices to patients who need them, at a fraction of the cost of a new device.

This can improve access to medical care for individuals who may not otherwise have access to it, and can help to improve health outcomes for patients who require these medical devices.

Pacemaker recycling programs are becoming increasingly common in the US.
Recycled pacemakers are refurbished to ensure that they meet the same safety and quality standards as new devices. Then, they’re made available at a significantly lower cost than a new pacemaker.

Recycled pacemakers are subject to the same regulations and standards as new pacemakers. That means they must be thoroughly tested and evaluated before they are made available for use to make sure they’re just as safe and effective as new devices.

If you or a loved one have a pacemaker, you can even make arrangements for it to be recycled after your death. Check out Project My Heart Your Heart below for an example. — WTF fun facts

WTF Fun Fact 13232 – Belief in Conspiracy Theories

According to psychological research, conspiracy theorists tend to score higher on measures of paranoia, distrust, and cynicism. They are more likely to have a suspicious and skeptical view of the world which can make them more likely to see hidden motives and conspiracies in events and the actions of others. The belief in conspiracy theories is multifaceted.

What research helps explain some people’s belief in conspiracy theories?

There are several psychological factors that contribute to why some people believe in conspiracy theories. One is the need for a sense of control and predictability. Conspiracy theories may offer a sense of control and predictability in a complex and uncertain world. By attributing events to a hidden, powerful force, people can feel like they understand why things are happening and that they have some control over their fate.

A variety of cognitive biases, such as the tendency to seek out information that confirms their existing beliefs and ignore information that contradicts them help influence people’s beliefs and reasoning. This can lead to a reinforcement of conspiracy beliefs and resistance to accepting evidence-based explanations.

People may be more likely to believe in conspiracy theories if they have a low level of trust in mainstream institutions. These usually include the government and media. Believers may view these institutions as untrustworthy or corrupt. This forces them to turn to alternative sources of information that support their beliefs.

Conspiracy theories can provide a sense of uniqueness and identity, particularly for individuals who feel marginalized or disconnected from mainstream society. Believing in a conspiracy theory can make people feel special and part of a group with shared beliefs.

People are more likely to believe in conspiracy theories when other believers are part of their social circle. Social influence can be a powerful motivator too. Most people are often more likely to adopt beliefs and attitudes that are prevalent within their social network.

A complex context

Research on the belief in conspiracy theories suggests that there’s more to it than just a lack of critical thinking or an overactive imagination. Instead, people’s belief in conspiracy theories may be rooted in deeper psychological processes and motivations.

According to psychological research, conspiracy theorists tend to score higher on measures of paranoia, distrust, and cynicism. They are more likely to have a suspicious and skeptical view of the world. This can make them more likely to see hidden motives and conspiracies in events and the actions of others.

Additionally, research has shown that conspiracy theorists tend to have a unique information-processing style, characterized by a tendency to selectively attend to and remember information that supports their beliefs, and to ignore or discount information that contradicts their beliefs. This can lead to a reinforcement of conspiracy beliefs and a resistance to accepting evidence-based explanations.

The cultural context for conspiracy theories

In a research article from Frontiers in Psychology (cited below) was conducted in three countries. Researchers assessed participants based on their levels of paranoia, conspiracy mentality, and mistrust of different institutions (e.g. government, media, science).

The results revealed that different forms of mistrust are associated with paranoid beliefs and conspiracy mentality. Paranoid beliefs associate more strongly with mistrust of government and interpersonal relationships, while conspiracy mentality associates more strongly with mistrust of media and science. — WTF fun facts

WTF Fun Fact 13224 – Full Moons in February

It’s possible to have no full moons in February. It doesn’t happen often, but February goes by without a full moon roughly every 19 years.

How can there be no full moons in February?

The lunar cycle starts with a new moon and ends with the next new moon.

The length of a lunar cycle is roughly 29.5 days. In a normal year, February has 28 days. This makes it shorter than the average length of a lunar cycle.

February does not have a full moon in a year when there are two full moons in January. This occurs approximately once every 19 years, as part of the Metonic cycle, which is a pattern of full and new moons repeating approximately every 19 years.

Recent years in which February did not have a full moon include 2018, 1999, 1980, 1961, and 1942.

What’s the significance of a full moon?

The gravitational pull of the moon and the sun causes the tides to rise and fall. The full moon has the strongest tidal effect because it is in direct line with the earth and the sun.

The full moon also provides brighter light at night. This can impact the behavior of nocturnal animals, such as owls and bats. It can also affect the migratory patterns of some species.

A full moon has the strongest effect on tides, and it is responsible for producing spring tides, which are the highest tides of the lunar cycle.

In some cultures, the full moon is used as a reference point for planting, harvesting, and other agricultural activities. And for many cultures and religions, the full moon has spiritual significance and is associated with rituals, ceremonies, and festivals.

In the future, February is expected not to have a full moon in 2037, 2056, 2075, and 2094.
