WTF Fun Fact 13300 – Swearing and Exercise

Exercise often needs to be hard to be productive. And that can be a frustrating experience. Maybe that’s why swearing and exercise go together to make you more productive. That’s right, recent research has suggested that swearing during exercise can help to alleviate pain, improve performance, and even reduce stress.

How swearing and exercise go together

According to a study published in the journal Psychology of Sport and Exercise, swearing during exercise can help to reduce the sensation of pain. For example, the study found that people who swore while squeezing a hand grip held on for longer and reported less pain than those who did not swear. That’s because swearing triggers the body’s fight-or-flight response. And this can help to increase pain tolerance and reduce the sensation of discomfort.

“Swearing appears to be able to bring about improvements in physical performance that may not be solely dependent on a stress response arising out of the shock value of the swearing,” Richard Stephens, the study’s co-author, said.

In addition to reducing pain, swearing can also improve performance during exercise.

A study found that athletes who swore before completing a physical task were able to produce more power and strength than those who did not swear. Letting out some choice curse words can increase your adrenaline levels and provide you with a burst of energy. These same things can help athletes perform at their best.

Let it out

Finally, swearing can also help to reduce stress and anxiety during exercise. That’s because swearing can help to regulate emotions and reduce feelings of stress and anxiety. It provides a cathartic release, which can help to improve mental wellbeing.

While swearing during exercise may not be suitable for everyone, there appear to be a number of benefits to using profanity during physical activity.

So next time you hit the gym, don’t be afraid to let out a few choice words – it could be just what you need to improve your performance and reduce pain and stress.

WTF Fun Fact 13016 – Petting an Animal Reduces Stress

You’ve probably heard that petting an animal reduces stress. If you’re lucky, you’ve even experienced it firsthand. And if you have the pleasure of consistently getting some hands-on time with a furry companion (or even a pal’s pet), you may not always notice it, but you probably do have less cortisol in your system.

How does petting an animal reduce stress?

One of the most oft-cited studies about the animals reducing our stress comes from a study in the journal of the American Educational Research Assocation (AERA). It was a rigorous study that controlled for multiple other factors, such as overall health of the subjects. And it found that just 10 minutes of petting a cat or dog (many of which happened to come from a shelter and probably benefitted from some socialization) results in measurably smaller levels of cortisol, the hormone that regulates our flight-or-fight response.

The research was done on college students (who often get stressed out around midterms and finals). And one of the best parts was that even brief animal encounters could help reduce stress levels.

The researchers didn’t find the same effect when students viewed photos of pets or saw them in person – the real benefits came from physical contact.

Details of the study

The researchers collected saliva samples from 249 college students who participated in one of four types of animal encounters. (Cortisol levels can be measured using saliva.)

  • 73 students got to pet the cats and dogs
  • 62 watched other people pet the animals
  • 57 watched a slideshow of images of the same animals
  • 57 remained on the waitlist

Saliva samples were collected first thing in the morning and then two more samples were collected 15 and 25 minutes after the animal encounter.

Students with hands-on animal interactions had the lowest cortisol levels, though it didn’t necessarily last throughout the day. Still, even momentary stress relief can help regulate stress.

The researchers hope the knowledge that petting animals reduces stress will help colleges (and others) help people regulate stress before it causes more serious physical and psychological disorders. — WTF fun facts

WTF Fun Fact 13008 – Financial Stress Lowers IQ

Fun Fact: “A Harvard study found that our IQs can drop by 13 points when we are under financial stress. This is in part due to the amount of brain power we use to think about any financial burdens we carry, causing distraction.”
Are you surprised to hear that financial stress lowers IQ?

***

According to Canada’s CBC News (cited below), “People struggling to pay their bills tend to temporarily lose the equivalent of 13 IQ points, scientists found when they gave intelligence tests to shoppers at a New Jersey mall and farmers in India. The idea is that the financial stress of trying to make ends meet monopolizes thinking, making other calculations slower and more difficult, sort of like the effects of going without sleep for a night.”

Financial stress and IQ

We know IQ tests aren’t reliable indicators of innate intelligence, but they can be used to measure changes in a person’s cognitive capacity under different conditions. In other words, we don’t have to compare a person’s scores to anyone else’s, we can compare their specific scores without making judgments about their overall intelligence.

CBC described the study:

“The scientists looked at the effects of finances on the brain both in the lab and in the field. In controlled lab-like conditions, they had about 400 shoppers at Quaker Bridge Mall in central New Jersey consider certain financial scenarios and tested their brain power. Then they looked at real life in the fields of India, where farmers only get paid once a year. Before the harvest, they take out loans and pawn goods. After they sell their harvest, they are flush with cash.

[Harvard researcher Sendhil] Mullainathan and colleagues tested the same 464 farmers before and after the harvest and their IQ scores improved by 25 per cent when their wallets fattened.”

What the study doesn’t mean

The study does not mean that rich people are smarter than people who are having temporary or long-term financial difficulties. It only means they have more cognitive resources to “spend.” They can think more clearly and concentrate better on other tasks since they’re not worried about money. — WTF fun facts

WTF Fun Fact 12764 – Mindfulness Meditation Changes the Brain

We need more large-scale studies to make definitive claims, but mindfulness meditation seems to have some cool cognitive benefits. In fact, we can see on brain scans that people who practice mindfulness meditation experience changes in their brains.

Minding your thoughts

Mindfulness practice encourages people to stop and spend time noticing their thoughts and then letting go of the ones that are negative, disorganized, or aren’t serving a positive purpose. It’s designed to help us notice and control our thinking. (As opposed to most meditation practices, which center around emptying the mind of thoughts.)

The part of the brain affected by mindfulness practice is called the amygdala. This is also called the “fight or flight” center because it is linked to fear and emotional responses. Brain scans have shown that mindfulness practice helps shrink the amygdala. While that may sound like a bad thing, an overactive amygdala can be bad for concentration, mood, and emotional regulation.

Regulating the amygdala

However, mindfulness has been shown to help increase the connections between the amygdala and prefrontal cortex. That’s a good thing because those connections help us regulate our emotional responses.

We need our amygdala, we just don’t want it to be hyperactive. And when we practice mindfulness, our bodies get better at regulating those emotional responses.

While some of the effects of mindfulness have been overstated in the press, there is evidence that it can modestly increase physical health and compassion and even reduce bias in addition to negative thought patterns.

The popularity of mindfulness meditation

A U.S. survey found that the percentage of adults practicing some type of mantra-based meditation, mindfulness meditation, or spiritual meditation in the previous year tripled between 2012 and 2017 (from 4.1% to 14.2%). Even among children (4 to 17 years of age), the percentage increased from less than 1% to over 5%. These emotional regulation techniques continue to grow in popularity.

Of course, there’s a lot we still don’t know about mindfulness and meditation in general, and they’re not always the best practices for everyone.

There are also different types of mindfulness meditation to practice, each with slightly different outcomes. For example, body scanning can help reduce negative thoughts. But practices in which participants are asked to observe their thoughts can sometimes lead to more negative thinking, especially among those who have just started practicing the skill and can’t let go of those thoughts easily.

In the end, it may be best for those who are new to mindfulness and observing their thoughts to do so with guidance from a teacher or tool so that they can stay on the right track and get the most out of their mindfulness practices. – WTF fun facts

WTF Fun Fact 12442 – The Power of Forest Bathing

In Japan, it’s called Shinrin-Yoku. The act of “forest bathing” may have started there, but people around the world are starting to see the benefits of not just spending time in nature, but doing so intentionally (and, importantly, not through the lens of a smartphone).

Forest bathing studies have been shown to have measurable beneficial effects. Much of this research has been conducted by Dr. Qing Li, physician and immunologist at Nippon Medical School Hospital in Tokyo. In his studies, participants are not asked to jog or even kike, but merely practice awareness while out in the woods.

His studies have found forest bathing can decrease stress and blood pressure, slow the heart rate, speed up digestion, help with insomnia, and reduce fatigue. Perhaps more surprisingly are its effects on immunity, particularly NK (or natural killer) cells, which play a role in helping the body fight off the growth of cancerous cells.

Trees release volatile organic compounds known as phytoncides. When we breathe these in, we get more of these beneficial effects.

So next time you find yourself in nature, take a mindful walk, listen to the sounds, notice the colors and textures, and breathe deep amongst the trees. – WTF fun facts
