Why Don't We Talk About Anxiety Disorder More Often?
Anxiety is now the number one disorder on the planet. Yet it's oddly ignored from public conversation.

The National Institute of Health estimates that one-third of all American adults and adolescents suffer from anxiety. That percentage is especially troubling for the latter group, prompting the NY Times to dedicate a magazine feature to the growing number of teens stricken by panic attacks. The World Health Organization recently named anxiety as the number one disorder on the planet, overtaking depression. Yet anyone who suffers from anxiety knows that depression is a close sibling; the two share many physiological similarities.
Every week I cover various studies and research papers on a variety of topics in fitness, health, and neuroscience. Some studies are small and need further research; others involve hundreds of thousands of people and took decades to complete. Each new study is a further jigsaw piece adding to this complex puzzle of our identity: how we react to various stimuli, how this chemical reacts in our bodies, how this nutrient affects our ability to focus or what it does to our weight.

I could share reams of data on anxiety; it’s a topic I’ve covered often in the past five years writing for this site. But one of the most important and under-discussed topics concerning anxiety disorder is beyond data: shame.
The Times piece makes a critical point: anxiety is the most common disorder on the planet and yet we rarely discuss it. Having suffered from it for twenty-five years, experiencing hundreds of attacks in public and at home, has taught me a thing or two about the condition. For most of that time I suffered quietly because I felt ashamed to admit to anyone what was going on. In the numerous discussions I've had since I opened up, I’ve discovered that many people feel the same way.
Anxiety is natural. It’s part of our threat detection system. But an unconscious process can trigger our sympathetic nervous system to fly into overdrive. By the time the cascade of effects surfaces in consciousness—a pending sense of doom, as if death is imminent; tingling in the extremities; out-of-body dizziness; the light sweat; the heart palpitations—you’re left wondering what triggered the attack this time, which forces you to focus on the attack, which emboldens it further. I’ve ended up curled in a ball on sidewalks and in emergency rooms just trying to breathe with no understanding as to why.
The oddest sensation in all of this is shame and, often, its cousin, embarrassment. We have a cultural pull-yourself-up-by-the-bootstraps mentality regarding stress. I was told to “get over it” many times. “It’s all in your head” is a mantra I’m quite familiar with. So you feel shame for being a weak creature, unable to piece together the parts that led to yet another attack. You feel horrible that the people around you have to deal with your insufficiencies, your inability to “pull it together.” The one time I blacked out in a restaurant from an attack, people eyed the glass of wine on my table suspiciously, even though I had only had one sip.
Anxiety needs to be discussed for what it is: an exploitation of an innate physiological system. The reasons for this exploitation are multifactorial. An addiction to technology is a serious and timely one. The economic divide is another. The insane number of inputs pressing in on us from every direction is crippling. This is not just anecdote. As of 2012, Americans were losing 321 million days of work every year due to anxiety and depression, costing the economy $50 billion. If more teens are dealing with this disorder those numbers will rise.

Workplace expectations play a key role. Seventy percent of office emails are opened an average of six seconds after receiving, yet it takes our brain twenty minutes to enter deep focus afterwards, by which time we'll probably have checked again, and again. The barrage of emails, and social media more broadly, is a modern extension of the Zeigarnik effect: we remember interrupted or uncompleted tasks more than completed ones. This is why multitasking is not only inefficient but also dangerous: those many little tasks consume our attention and keep us on edge about all we have in front of us.
As with any addiction, the email dopamine squirt loses strength through repetition, requiring more checks. As losing focus on what's in front of us leaves us unfulfilled, we turn to our phones for more joy, which results in more addiction. Chronic anxiety is different than full-blown panic attacks in that it's like an annoying background noise, always simmering below the surface. You become accustomed to it. Then, when the tension erupts, it seems as if out of nowhere, though the stress was there all along.
Technology is not the only trigger of anxiety, though it could well account for the massive increase in reported anxiety worldwide. When we’re stressed, our memory suffers, our immune system suffers, and, worst of all, our sleep suffers, which creates system-wide havoc. Multitasking increases levels of cortisol and adrenaline, creating a mental fog that's tough to shake. When we're chronically taxed, we’re more likely to act aggressively or impulsively. Since willpower is a limited resource, the tension is more difficult to fend off at night, keeping us up later, causing us to eat more carb-heavy comfort foods, increasing the likelihood of scrolling through our feeds to distract our overactive minds when, really, that’s the worst solution.
Since we've socially agreed that crossing streets and driving while texting is acceptable behavior, anxiety is not going to be diminished anytime soon. Corporations and small companies alike have extended their reach into your evening and morning hours. The rest of the time is dominated by social media. In 2008, adults spent a daily average of eighteen minutes on their phones. By 2015 that number had jumped to two hours and forty-eight minutes. If humans evolved thanks to an acute awareness of our environment, many would now be absolutely useless if we actually had to work to survive.

But this is the environment we are in, and it's exhausting. Health care costs the United States two trillion dollars a year, 20 percent of GDP. It is estimated that 70% of treated illnesses are preventable. Anxiety is one of those diseases. Unfortunately you can’t willpower your way through it. There are techniques for overcoming it, but you have to replace bad habits and implement good ones—regenerative movement; down regulation techniques like yoga, meditation, and breathing exercises; reframing your work day to focus on single tasks; treating the physiological responses as motivational energy rather than an existential dilemma; sleeping at least seven hours every night—for sustainable changes to occur.
Most important is simply talking about it. Anthropological consensus states group fitness is one of the, if not the, deciding factor in our worldwide species domination. Social networks—real, flesh and blood connections—are essential for survival, psychologically and physically. That means relying on others to work through the overwhelming burden of anxiety plaguing our world. There is no shame in suffering from this disease. But it is a shame when you don't reach out for help.

No, the Yellowstone supervolcano is not ‘overdue’
Why mega-eruptions like the ones that covered North America in ash are the least of your worries.
Ash deposits of some of North America's largest volcanic eruptions.
- The supervolcano under Yellowstone produced three massive eruptions over the past few million years.
- Each eruption covered much of what is now the western United States in an ash layer several feet deep.
- The last eruption was 640,000 years ago, but that doesn't mean the next eruption is overdue.
The end of the world as we know it

Of the many freak ways to shuffle off this mortal coil – lightning strikes, shark bites, falling pianos – here's one you can safely scratch off your worry list: an outbreak of the Yellowstone supervolcano.
As the map below shows, previous eruptions at Yellowstone were so massive that the ash fall covered most of what is now the western United States. A similar event today would not only claim countless lives directly, but also create enough subsidiary disruption to kill off global civilisation as we know it. A relatively recent eruption of the Toba supervolcano in Indonesia may have come close to killing off the human species (see further below).
However, just because a scenario is grim does not mean that it is likely (insert topical political joke here). In this case, the doom mongers claiming an eruption is 'overdue' are wrong. Yellowstone is not a library book or an oil change. Just because the previous mega-eruption happened long ago doesn't mean the next one is imminent.

This map shows the location of the Yellowstone plateau and the ash beds deposited by its three most recent major outbreaks, plus two other eruptions – one similarly massive, the other the most recent one in North America.
Huckleberry Ridge
The Huckleberry Ridge eruption occurred 2.1 million years ago. It ejected 2,450 km3 (588 cubic miles) of material, making it the largest known eruption in Yellowstone's history and in fact the largest eruption in North America in the past few million years.
This is the oldest of the three most recent caldera-forming eruptions of the Yellowstone hotspot. It created the Island Park Caldera, which lies partially in Yellowstone National Park, Wyoming and westward into Idaho. Ash from this eruption covered an area from southern California to North Dakota, and southern Idaho to northern Texas.
Mesa Falls
About 1.3 million years ago, the Mesa Falls eruption ejected 280 km3 (67 cubic miles) of material and created the Henry's Fork Caldera, located in Idaho, west of Yellowstone.
It was the smallest of the three major Yellowstone eruptions, both in terms of material ejected and area covered: 'only' most of present-day Wyoming, Colorado, Kansas and Nebraska, and about half of South Dakota.
Lava Creek
The Lava Creek eruption was the most recent major eruption of Yellowstone: about 640,000 years ago. It was the second-largest eruption in North America in the past few million years, creating the Yellowstone Caldera.
It ejected only about 1,000 km3 (240 cubic miles) of material, i.e. less than half of the Huckleberry Ridge eruption. However, its debris is spread out over a significantly wider area: basically, Huckleberry Ridge plus larger slices of both Canada and Mexico, plus most of Texas, Louisiana, Arkansas, and Missouri.
Long Valley
This eruption occurred about 760,000 years ago. It was centered on southern California, where it created the Long Valley Caldera, and spewed out 580 km3 (139 cubic miles) of material. This makes it North America's third-largest eruption of the past few million years.
The material ejected by this eruption is known as the Bishop ash bed, and covers the central and western parts of the Lava Creek ash bed.
Mount St Helens
The eruption of Mount St Helens in 1980 was the deadliest and most destructive volcanic event in U.S. history: it created a mile-wide crater, killed 57 people and created economic damage in the neighborhood of $1 billion.
Yet by Yellowstone standards, it was tiny: Mount St Helens only ejected 0.25 km3 (0.06 cubic miles) of material, most of the ash settling in a relatively narrow band across Washington State and Idaho. By comparison, the Lava Creek eruption left a large swathe of North America in up to two metres of debris.
The difference between quakes and faults
The volume of dense rock equivalent (DRE) ejected by the Huckleberry Ridge event dwarfs all other North American eruptions. It is itself overshadowed by the DRE ejected at the most recent eruption at Toba (present-day Indonesia). This was one of the largest known eruptions ever and a relatively recent one: only 75,000 years ago. It is thought to have caused a global volcanic winter which lasted up to a decade and may be responsible for the bottleneck in human evolution: around that time, the total human population suddenly and drastically plummeted to between 1,000 and 10,000 breeding pairs.

So, what are the chances of something that massive happening anytime soon? The aforementioned mongers of doom often claim that major eruptions occur at intervals of 600,000 years and point out that the last one was 640,000 years ago. Except that (a) the first interval was about 200,000 years longer, (b) two intervals is not a lot to base a prediction on, and (c) those intervals don't really mean anything anyway. Not in the case of volcanic eruptions, at least.
Earthquakes can be 'overdue' because the stress on fault lines is built up consistently over long periods, which means quakes can be predicted with a relative degree of accuracy. But this is not how volcanoes behave. They do not accumulate magma at constant rates. And the subterranean pressure that causes the magma to erupt does not follow a schedule.
What's more, previous super-eruptions do not necessarily imply future ones. Scientists are not convinced that there ever will be another big eruption at Yellowstone. Smaller eruptions, however, are much likelier. Since the Lava Creek eruption, there have been about 30 smaller outbreaks at Yellowstone, the last lava flow being about 70,000 years ago.
As for the immediate future (give or take a century): the magma chamber beneath Yellowstone is only 5 percent to 15 percent molten. Most scientists agree that is as un-alarming as it sounds. And that its statistically more relevant to worry about death by lightning, shark, or piano.

Smartly dressed: Researchers develop clothes that sense movement via touch
Measuring a person's movements and poses, smart clothes could be used for athletic training, rehabilitation, or health-monitoring.
In recent years there have been exciting breakthroughs in wearable technologies, like smartwatches that can monitor your breathing and blood oxygen levels.
But what about a wearable that can detect how you move as you do a physical activity or play a sport, and could potentially even offer feedback on how to improve your technique?
And, as a major bonus, what if the wearable were something you'd actually already be wearing, like a shirt of a pair of socks?
That's the idea behind a new set of MIT-designed clothing that use special fibers to sense a person's movement via touch. Among other things, the researchers showed that their clothes can actually determine things like if someone is sitting, walking, or doing particular poses.
The group from MIT's Computer Science and Artificial Intelligence Lab (CSAIL) says that their clothes could be used for athletic training and rehabilitation. With patients' permission, they could even help passively monitor the health of residents in assisted-care facilities and determine if, for example, someone has fallen or is unconscious.
The researchers have developed a range of prototypes, from socks and gloves to a full vest. The team's "tactile electronics" use a mix of more typical textile fibers alongside a small amount of custom-made functional fibers that sense pressure from the person wearing the garment.
According to CSAIL graduate student Yiyue Luo, a key advantage of the team's design is that, unlike many existing wearable electronics, theirs can be incorporated into traditional large-scale clothing production. The machine-knitted tactile textiles are soft, stretchable, breathable, and can take a wide range of forms.
"Traditionally it's been hard to develop a mass-production wearable that provides high-accuracy data across a large number of sensors," says Luo, lead author on a new paper about the project that is appearing in this month's edition of Nature Electronics. "When you manufacture lots of sensor arrays, some of them will not work and some of them will work worse than others, so we developed a self-correcting mechanism that uses a self-supervised machine learning algorithm to recognize and adjust when certain sensors in the design are off-base."
The team's clothes have a range of capabilities. Their socks predict motion by looking at how different sequences of tactile footprints correlate to different poses as the user transitions from one pose to another. The full-sized vest can also detect the wearers' pose, activity, and the texture of the contacted surfaces.
The authors imagine a coach using the sensor to analyze people's postures and give suggestions on improvement. It could also be used by an experienced athlete to record their posture so that beginners can learn from them. In the long term, they even imagine that robots could be trained to learn how to do different activities using data from the wearables.
"Imagine robots that are no longer tactilely blind, and that have 'skins' that can provide tactile sensing just like we have as humans," says corresponding author Wan Shou, a postdoc at CSAIL. "Clothing with high-resolution tactile sensing opens up a lot of exciting new application areas for researchers to explore in the years to come."
The paper was co-written by MIT professors Antonio Torralba, Wojciech Matusik, and Tomás Palacios, alongside PhD students Yunzhu Li, Pratyusha Sharma, and Beichen Li; postdoc Kui Wu; and research engineer Michael Foshey.
The work was partially funded by Toyota Research Institute.

Do you worry too much? Stoicism can help
How imagining the worst case scenario can help calm anxiety.
Stoicism can help overcome anxiety
- Stoicism is the philosophy that nothing about the world is good or bad in itself, and that we have control over both our judgments and our reactions to things.
- It is hardest to control our reactions to the things that come unexpectedly.
- By meditating every day on the "worst case scenario," we can take the sting out of the worst that life can throw our way.
Are you a worrier? Do you imagine nightmare scenarios and then get worked up and anxious about them? Does your mind get caught in a horrible spiral of catastrophizing over even the smallest of things? Worrying, particularly imagining the worst case scenario, seems to be a natural part of being human and comes easily to a lot of us. It's awful, perhaps even dangerous, when we do it.
But, there might just be an ancient wisdom that can help. It involves reframing this attitude for the better, and it comes from Stoicism. It's called "premeditation," and it could be the most useful trick we can learn.
Practical Stoicism
Broadly speaking, Stoicism is the philosophy of choosing your judgments. Stoics believe that there is nothing about the universe that can be called good or bad, valuable or valueless, in itself. It's we who add these values to things. As Shakespeare's Hamlet says, "There is nothing either good or bad, but thinking makes it so." Our minds color the things we encounter as being "good" or "bad," and given that we control our minds, we therefore have control over all of our negative feelings.
Put another way, Stoicism maintains that there's a gap between our experience of an event and our judgment of it. For instance, if someone calls you a smelly goat, you have an opportunity, however small and hard it might be, to pause and ask yourself, "How will I judge this?" What's more, you can even ask, "How will I respond?" We have power over which thoughts we entertain and the final say on our actions. Today, Stoicism has influenced and finds modern expression in the hugely effective "cognitive behavioral therapy."

One of the principal fathers of ancient Stoicism was the Roman statesmen, Seneca, who argued that the unexpected and unforeseen blows of life are the hardest to take control over. The shock of a misfortune can strip away the power we have to choose our reaction. For instance, being burglarized feels so horrible because we had felt so safe at home. A stomach ache, out of the blue, is harder than a stitch thirty minutes into a run. A sudden bang makes us jump, but a firework makes us smile. Fell swoops hurt more than known hardships.
What could possibly go wrong?
So, how can we resolve this? Seneca suggests a Stoic technique called "premeditatio malorum" or "premeditation." At the start of every day, we ought to take time to indulge our anxious and catastrophizing mind. We should "rehearse in the mind: exile, torture, war, shipwreck." We should meditate on the worst things that could happen: your partner will leave you, your boss will fire you, your house will burn down. Maybe, even, you'll die.
This might sound depressing, but the important thing is that we do not stop there.
Stoicism has influenced and finds modern expression in the hugely effective "cognitive behavioral therapy."
The Stoic also rehearses how they will react to these things as they come up. For instance, another Stoic (and Roman Emperor) Marcus Aurelius asks us to imagine all the mean, rude, selfish, and boorish people we'll come across today. Then, in our heads, we script how we'll respond when we meet them. We can shrug off their meanness, smile at their rudeness, and refuse to be "implicated in what is degrading." Thus prepared, we take control again of our reactions and behavior.
The Stoics cast themselves into the darkest and most desperate of conditions but then realize that they can and will endure. With premeditation, the Stoic is prepared and has the mental vigor necessary to take the blow on the chin and say, "Yep, l can deal with this."
Catastrophizing as a method of mental inoculation
Seneca wrote: "In times of peace, the soldier carries out maneuvers." This is also true of premeditation, which acts as the war room or training ground. The agonizing cut of the unexpected is blunted by preparedness. We can prepare the mind for whatever trials may come, in just the same way we can prepare the body for some endurance activity. The world can throw nothing as bad as that which our minds have already imagined.
Stoicism teaches us to embrace our worrying mind but to embrace it as a kind of inoculation. With a frown over breakfast, try to spend five minutes of your day deliberately catastrophizing. Get your anti-anxiety battle plan ready and then face the world.

Study: People will donate more to charity if they think something’s in it for them
A study on charity finds that reminding people how nice it feels to give yields better results than appealing to altruism.
