For thoughtful conversations about mental health, modern life, human biology, and what it means to stay connected in a disconnected world.
A major Lancet analysis from the Global Burden of Disease study estimated that 1.17 billion people were living with a mental disorder in 2023.. Researchers estimated that number at around 599 million in 1990. Put another way, the number of people living with mental disorders has nearly doubled over three decades. (sciencemediacentre.es)
At first, a statistic like that can feel distant. It can sound like another headline, another number, or another global report telling us that people are struggling.
However, this number matters.
It tells us that mental illness is not rare. It is not some isolated personal defect. Nor is it simply a matter of weakness, poor attitude, bad choices, or lack of motivation.
When more than a billion people are living with mental disorders, we are no longer talking about individual failure.
We are talking about a human problem.
More importantly, we may be talking about a world that is asking more from the human nervous system than it was ever designed to carry.
That idea sits at the heart of much of my work on modern life and mental health: the belief that many people are not broken, but biologically overwhelmed by a world that often ignores what human beings actually need.
What Mental Illness Worldwide Is Really Telling Us
The study examined mental disorders across more than 200 countries and territories. It looked at a range of conditions, including anxiety disorders, major depressive disorder, bipolar disorder, schizophrenia, eating disorders, attention-deficit/hyperactivity disorder, autism spectrum disorder, conduct disorder, and others. (sciencemediacentre.es)
Among those conditions, anxiety and depression were especially common.
That should not surprise us.
Many people today are living in a constant state of pressure. They are trying to survive financially, stay emotionally steady, maintain relationships, manage family responsibilities, keep up with work, process endless information, and navigate a world that often feels unstable.
Anxiety and depression are not just abstract diagnoses. They affect how people think, feel, connect, work, parent, rest, and move through daily life. I have written more about this in Types of Depression and Anxiety Is Not Weakness — It’s the Brain’s Survival System.
For many people, pressure builds slowly until everyday life starts to feel heavier than it should. That is why I often return to articles like Why Anxiety Makes Small Problems Feel Overwhelming, because small things rarely feel small when the nervous system is already overloaded.
On the outside, many still look fine.
They go to work. They answer messages. They smile when they have to. Somehow, they keep showing up and doing what is expected.
Inside, however, their nervous system may be exhausted.

This is something we often fail to understand.
Mental health struggles are not always visible. They do not always announce themselves loudly. Sometimes they show up as fatigue. Other times, they appear as irritability, avoidance, numbness, or a slow withdrawal from the world because everything has started to feel like too much.
Too often, when people reach that point, they blame themselves.
The Major Types of Depression — And Why They Feel Different
Depression isn’t one single experience. Major depression, dysthymia, bipolar depression, and seasonal depression reflect different biological and emotional patterns beneath the same word. Understanding the types helps replace shame with clarity — and supports more meaningful recovery.
The Research Is Important — But It Has Limits
This is also why I believe mental health conversations need to move beyond labels alone. Diagnosis can be helpful, but understanding the biology underneath distress can reduce shame. I explore that idea more directly in The Brain’s Alarm System.
The research matters, but it also needs to be understood carefully.
Large global studies like the Global Burden of Disease study are useful because they help researchers compare patterns across countries, populations, and time. They offer a broader picture than any single clinic, hospital, survey, or country could provide on its own.
Still, these numbers are estimates.
They rely on available data, modelling, diagnostic categories, national reporting systems, and assumptions that may vary from place to place. Some countries have stronger mental health data than others. Certain populations are easier to study. Many people never receive a diagnosis at all.
For that reason, the figure should not be read as a perfect headcount of every person suffering in silence. It is an estimate based on the best available data.
There is also the issue of awareness.
Part of the increase from 1990 to 2023 may reflect better diagnosis, better reporting, population growth, and greater public awareness. Experts responding to the study also noted several important limitations, including uneven geographic coverage, differences in data quality, reliance on diagnostic definitions that may not translate perfectly across cultures, and the exclusion of substance use disorders from this specific analysis. (sciencemediacentre.es)
That matters.
“Many people are not broken. They are biologically overwhelmed by a world that often ignores what human beings actually need.”
We should not automatically assume that every part of the increase means the world has become twice as mentally unwell in a simple, direct way.
At the same time, we should be careful not to dismiss the finding.
Even if improved reporting explains part of the rise, it does not explain away the suffering. It does not erase the fact that mental disorders are now among the largest sources of disability in the world. ABC News reported that the study found mental disorders now account for more than 17 percent of all disability worldwide. (abc.net.au)
In other words, the research gives us a signal.
It is not a perfect picture.
Even so, it is a signal strong enough that we should pay attention.
This Is Not Just About Better Diagnosis
It would be easy to say, “Well, we are just better at diagnosing mental illness now.”
There is some truth in that.
But it is not enough.
If more people are being diagnosed, we still need to ask why so many people are struggling in the first place. Greater awareness may explain why more suffering is being counted. It does not fully explain why so many people feel anxious, depressed, disconnected, overwhelmed, and emotionally exhausted.
Therefore, we need to ask harder questions.
What kind of pace are we normalizing?
How much loneliness are we tolerating?
Why are so many young people growing up under constant pressure?
What kind of culture teaches people to perform strength while quietly falling apart?
These are not small questions.
They are the questions we should have been asking all along.
The Simple Habits That Support Mental Health in Everyday Life
As spring arrives, it’s essential to remember that mental health renewal often stems from small, daily habits rather than dramatic changes. Simple practices, such as morning sunlight, movement, connection with others, and moments of rest, can significantly enhance well-being. Prioritizing these habits fosters emotional balance and resilience in our hectic lives.
The Nervous System Was Not Built for This Much Pressure
One of the biggest mistakes we make in mental health is treating the mind as if it exists separately from the body.
It does not.
Anxiety, depression, burnout, irritability, emotional shutdown, and overwhelm are not just “thought problems.” Often, they are nervous system problems.
They are biological responses to stress, uncertainty, threat, exhaustion, isolation, grief, pressure, and overload.
The human brain was not built for constant notifications, endless comparison, economic insecurity, social fragmentation, artificial urgency, and the feeling that we must always be available, informed, productive, and emotionally composed.
Eventually, the system begins to strain.
This is why I often return to the nervous system in my writing. Anxiety is not simply weakness or overthinking. In many cases, it is the brain’s survival system trying to protect us, even when the threat is not as immediate as it feels. I explore this more deeply in Anxiety Is Not Weakness — It’s the Brain’s Survival System.

That strain does not always look dramatic.
Sometimes it looks like someone who cannot relax.
For another person, it may look like avoiding messages because every reply feels like another demand.
In another case, it may look like someone who wants to leave the house but cannot seem to get through the door.
It can also look like someone saying, “I’m fine,” because they do not know how to explain what is happening inside them.
At a wider level, it can look like a society full of people who are functioning just enough to keep everything moving, but not well enough to feel truly alive.
We Have Individualized a Collective Problem
Personal responsibility matters.
Sleep matters. Movement matters. Food matters. Therapy can matter. Medication can matter. Connection matters. Daily habits matter.
The choices we make can absolutely shape our mental health.
However, personal tools cannot fully solve a collective problem.
That is where the conversation often goes wrong.
We tell people to manage their anxiety without asking why so many people feel unsafe.
We encourage resilience without asking why life has become so relentlessly demanding.
Self-care is promoted everywhere, yet many people are living in survival mode.
People are told to reach out, while culture keeps becoming busier, more distracted, more isolated, and more emotionally guarded.
Mental health is personal.
But it is not only personal.
That distinction matters.
When we make mental illness only about the individual, we add shame to suffering. People begin to feel as though they are failing at life when they may actually be responding normally to abnormal levels of stress, disconnection, and pressure.
We’re Seeing Our Friends Less — and Our Nervous Systems Are Paying the Price
Canadians are spending less time with friends than ever before. Not because connection has lost its value, but because modern life has quietly made it harder to sustain.
Keep readingLoneliness Is Not a Small Issue
One of the most important pieces of this conversation is social connection.
Human beings are wired for connection. We are social mammals. Our brains and nervous systems developed in environments where belonging, cooperation, recognition, and shared responsibility were essential for survival.
Being seen mattered.
Support mattered too.
Having a place in the group mattered.
Yet modern life often pushes us in the opposite direction.
Today, we can order food without speaking to anyone. Remote work can remove casual social contact. Social media lets us scroll through hundreds of lives without truly connecting to a single person. Even in our own neighbourhoods, many people barely know one another.
That is part of what I explore in The Friendship Recession — Modern Loneliness, where I look at how modern life has quietly weakened the everyday bonds that help people feel grounded, seen, and supported.
Convenience has given us speed.
However, it has also quietly removed many of the small interactions that helped regulate us.
A smile from a familiar face. A brief conversation. A sense of being known. A shared routine. A reason to leave the house. Someone noticing when we are not there.
These things may seem small.
Biologically, they are not.
They are part of how human beings regulate stress. They help us feel safe. They also remind us that we belong to something larger than ourselves.
When those small points of connection disappear, the nervous system notices.
Even when we do not.
Young People Are Carrying a Heavy Load
The study also pointed to a heavy burden among young people, with the highest incidence observed among those aged 15 to 19. (sciencemediacentre.es)
That should concern all of us.
Adolescence has always been emotionally intense. Today, however, young people are growing up inside a world of constant comparison, online judgment, academic pressure, economic uncertainty, disrupted social development, and digital environments that often reward appearance, outrage, and performance over depth, rest, and belonging.
This is not about blaming technology alone.
Rather, it is about recognizing that the human brain develops through relationship, safety, play, challenge, rest, and meaningful connection.
When those things are replaced by pressure, comparison, overstimulation, isolation, and fear of being judged, rising distress should not surprise us.
Young people do not need more shame.
They need adults willing to take the environment seriously.
They need us to stop pretending the problem is simply that they are too sensitive, too weak, or too unwilling to cope.
Maybe some of them are overwhelmed because the world they are growing up in is overwhelming.

Mental Illness Is Not Weakness — It Is Information
One of the most damaging myths about mental illness is that it means something is wrong with the person.
But what if mental illness is also information?
Rising anxiety may be telling us that many people do not feel safe.
Increasing depression may point to a loss of meaning, community, purpose, and hope.
Emotional exhaustion may be warning us that the pace of modern life is biologically unsustainable.
Loneliness may not be only a private sadness. It may also be a warning light on the dashboard of society.
Of course, this does not mean every mental health struggle is caused by society.
Biology matters. Genetics matter. Family history matters. Post-traumatic stress disorder matters. Loss matters. Personal circumstances matter. Individual choices matter.
Still, people do not struggle in a vacuum.
Human beings are shaped by their environments.
Right now, many of our environments are making it harder to be well.
We Need a More Honest Mental Health Conversation
The finding that nearly 1.2 billion people are living with mental disorders should not only make us concerned.
It should make us honest.
We need to move beyond shallow conversations about self-care and into deeper conversations about what human beings actually need.
We need connection.
We need safety.
Rest matters too.
Purpose matters.
So does nature, community, meaningful relationships, and systems that understand the nervous system instead of constantly overwhelming it.
Mental illness should not be treated as though it is always a private weakness hiding inside the individual.
Sometimes the pain people carry is personal.
Sometimes it is biological.
Sometimes it is social.
Often, it is all three.
Why This Is Also the Conversation Behind Wired to Be Human
This is the larger conversation I explore in my book, Wired to Be Human.
The book looks at the growing mismatch between modern life and human biology. It asks why so many people feel anxious, disconnected, overstimulated, lonely, and emotionally exhausted in a world that is supposedly more convenient than ever.
Most mental health advice focuses on coping.
However, coping is only part of the story.
We also need to understand why modern life feels so overwhelming in the first place. That means looking at the nervous system, social connection, convenience culture, stress, belonging, and the biological needs that still shape human well-being.
That is what Wired to Be Human is about.
It is not a clinical textbook. Instead, it is a human conversation about biology, modern life, and why so many people feel like something is wrong with them when, in many cases, their nervous system may be responding to a world that has become deeply misaligned with what human beings need.

A More Human Way Forward
If more than a billion people are struggling, the answer cannot simply be to tell everyone to cope better.
We need better mental health care. Access to support must improve. Early intervention matters. Stigma needs to be challenged. Workplaces, schools, communities, and families need to understand that human beings are not machines.
The World Health Organization has also warned that more than one billion people are living with mental health disorders and that greater global investment is needed to scale up services. Its 2025 release noted that anxiety and depression remain highly prevalent, while mental health conditions continue to place enormous human and economic strain on individuals, families, communities, and countries. (who.int)
Clinical care matters deeply.
But care alone is not the whole answer.
We also need a cultural shift.
We need to ask whether the way we are living is aligned with the way human beings are built.
Because we are not endlessly adaptable.
We are biological beings.
“When more than a billion people are living with mental disorders, we are no longer talking about individual failure. We are talking about a human problem.”
We need sleep. We need belonging. We need movement. Sunlight matters. Emotional safety matters. Real conversations matter. Time away from constant stimulation matters too.
For people looking for practical ways to support their mental health in everyday life, I also wrote about simple grounding habits in The Simple Habits That Support Mental Health in Everyday Life.
Mental health does not improve only by treating symptoms after people break down.
It improves when we build lives, communities, and systems that stop pushing people toward the edge in the first place.
The statistic is alarming.
At the same time, it is also an invitation.
An invitation to stop blaming people for struggling.
An invitation to take modern life seriously.
Most of all, it is an invitation to understand mental illness not as a failure of character, but as a sign that something in the human system — personal, biological, social, or cultural — needs care.
Nearly 1.2 billion people are living with mental illness.
That should not make us look away.
It should make us pay attention.
