What Is Climate Anxiety?
You are lying in bed at 2 a.m. The day is done, the house is quiet, and your mind drifts to the wildfire smoke that blanketed your neighbourhood last summer. To the flooding you saw on the news. To the question you cannot shake: what kind of world are we leaving behind?
If that sounds familiar, you are not alone. Climate anxiety, sometimes called eco-anxiety, is the distress people feel in response to climate change and environmental degradation. It is not a clinical diagnosis. The American Psychological Association describes it as "a chronic fear of environmental doom." And a growing body of research suggests it is one of the defining emotional experiences of our time.
Here is the important part: climate anxiety is not irrational. It is a reasonable emotional response to a real and documented threat. The goal is not to stop caring. It is to find ways to carry that concern without it stealing your sleep.
How Eco-Anxiety Disrupts Sleep
Worry and sleep have always been poor bedfellows. But climate anxiety has a particular quality that makes it especially disruptive at night. Unlike a work deadline or a relationship problem, the climate crisis has no clear endpoint. There is no single action you can take to resolve it before morning.
That open-ended quality feeds what psychologists call rumination, the repetitive cycling of anxious thoughts that keeps the nervous system activated when it should be winding down. Your body stays in a low-grade fight-or-flight state. Heart rate stays elevated. Cortisol does not drop on schedule. And sleep either will not come, or it fragments through the night.
What the Research Shows
A 2021 cross-sectional study spanning 25 countries found that negative emotions about climate change were significantly associated with insomnia symptoms and poorer self-rated mental health. A 2025 study published in the Annals of the New York Academy of Sciences added nuance: while climate anxiety does correlate with insomnia on its own, financial stress, health anxiety, and loneliness were stronger predictors of sleep disruption when all factors were measured together. The takeaway? Climate worry rarely acts alone. It often layers on top of other stresses, and that combination can be what tips sleep over the edge.
For younger adults especially, the pattern can look like this: doomscrolling climate news before bed, lying awake with existential dread, sleeping poorly, waking exhausted, and feeling less capable of doing anything about the problem. It becomes a cycle. The relationship between sleep and mental health runs both ways. Poor sleep worsens anxiety, and anxiety worsens sleep.
The Canadian Picture: Eco-Anxiety Hits Close to Home
Canadians are not watching climate change from a distance. We are living it.
A 2023 national survey by researchers Galway and Field, published in The Journal of Climate Change and Health, surveyed 1,000 young Canadians aged 16 to 25. The findings were striking:
- 78% said climate change affects their overall mental health
- 73% said the future is frightening
- 58% reported feeling afraid, sad, anxious, and powerless
- Nearly 40% said climate feelings negatively affect their daily functioning
- 48% said they believe humanity is doomed
These are not abstract statistics. They describe the inner lives of young people across this country, including many right here in Ontario.
Climate Events Ontario Has Lived Through
In 2023, Canada experienced its worst wildfire season in recorded history. Over 18.4 million hectares burned, more than double the previous record. Smoke blanketed southern Ontario for weeks, turning skies orange and driving air quality readings to hazardous levels. In 2021, British Columbia's heat dome killed over 600 people. Flooding in Ontario and Quebec has become a near-annual event. For many Canadians, including families in Brantford and the surrounding Grand River area, these are not distant headlines. They are memories.
The global picture is consistent. The landmark 2021 Lancet Planetary Health survey of 10,000 young people across ten countries found that 75% agreed "the future is frightening," and more than 45% said climate distress affected their daily functioning, including sleep.
When the Environment Literally Keeps You Awake
Climate anxiety is psychological. But climate change also disrupts sleep in direct, physical ways.
Heat. Research published in Science Advances found that rising nighttime temperatures are already eroding sleep worldwide. Even a modest 1-degree Celsius increase at night leads to measurable sleep loss. During heat events, your body cannot complete its natural cooling process, which is essential for falling and staying asleep. A systematic review in Sleep Medicine Reviews (2024) confirmed that higher outdoor and indoor temperatures are consistently associated with degraded sleep quality and quantity. For people who already struggle with nervous system regulation at bedtime, heat makes everything harder.
Wildfire smoke. Poor air quality irritates airways, worsens respiratory conditions, and can fragment sleep even in people who are otherwise healthy. After the 2023 wildfire season, Ontario emergency departments saw significant increases in respiratory-related visits.
Extreme weather events. Evacuations, power outages, and property damage cause acute stress that can trigger insomnia lasting weeks or months after the event itself.
So when someone says climate change is keeping them awake, they may mean it both figuratively and literally.
Evidence-Based Coping Strategies for Climate Anxiety and Sleep
The research is clear that dismissing climate anxiety does not help. Telling someone to "just stop worrying" about something genuinely dangerous is neither kind nor effective. What does help is channelling that concern in ways that allow you to function, sleep, and keep going.
Practical Steps for Better Sleep When Climate Worry Runs High
- Set a doomscroll curfew: Stop consuming climate news at least 90 minutes before bed. The information will still be there tomorrow. Your sleep cannot wait. If you find it hard to put your phone away at bedtime, try leaving it in another room entirely.
- Try worry journaling: Spend 10 minutes before your wind-down writing out your climate concerns. Research on expressive writing shows that externalizing worries reduces their power to intrude during sleep.
- Channel anxiety into action: Volunteer with a local environmental group, reduce your household footprint, or attend a municipal meeting. A sense of agency is one of the strongest antidotes to helplessness. The Galway and Field survey found that 71% of young Canadians still believe collective action can make a difference.
- Connect with community: Climate grief is easier to carry when shared. Talk to friends, join a climate cafe, or find a local group through organizations like Climate Reality Canada.
- Protect your sleep routine: Consistent wake times, cool bedroom temperatures (18 to 20 degrees Celsius), and a calming pre-bed routine matter more than ever when background anxiety is elevated.
- Consider professional support: If climate anxiety is significantly affecting your sleep and daily life, a therapist trained in eco-distress can help. This is not weakness. It is maintenance.
For young people especially, validation matters. If a teenager in your life says they are scared about the climate, listen. Their concern is grounded in evidence. Help them find constructive outlets rather than minimizing what they feel.

Sleep Environment Choices That Align With Your Values
Here is where the mattress conversation enters, and we will keep it honest.
A mattress will not solve climate change. But the choices you make about your sleep environment can address both the physical and psychological dimensions of eco-anxiety.
During heat events, your mattress and bedding play a real role in thermal comfort. Dense memory foam traps body heat. Materials like latex, innerspring systems with airflow channels, and moisture-wicking fabrics help your body cool naturally. If you have noticed that summers are getting harder to sleep through, a cooling mattress designed for Canadian climates can make a measurable difference.
For eco-conscious sleepers, choosing bedding made from organic and sustainably sourced materials can reduce one small source of dissonance. Products made with organic cotton, natural latex, and responsibly sourced wool are available from manufacturers like Natura, and they tend to last longer than their synthetic counterparts, which means less in the landfill.
We are not suggesting that buying an organic pillow will cure eco-anxiety. But when your values and your daily choices line up, it removes one more thing to lie awake thinking about.
Frequently Asked Questions
Is climate anxiety a mental health disorder?
No. Climate anxiety is not a recognized clinical diagnosis. It is considered a rational emotional response to a real environmental threat. That said, if it significantly disrupts your sleep, work, or relationships, speaking with a mental health professional can help you develop coping strategies.
What age group is most affected by eco-anxiety?
Research consistently shows that young people aged 16 to 35 report the highest levels of climate anxiety. The 2021 Lancet Planetary Health survey found that 75% of young people across ten countries described the future as frightening. A Canadian survey found similar rates among 16 to 25 year olds.
Can a mattress actually help with climate-related sleep problems?
During heat events, yes. Mattresses with cooling properties (natural latex, innerspring airflow, gel-infused foams) help regulate body temperature at night. At Mattress Miracle in Brantford, we carry several options designed for hot sleepers, and we are happy to help you find the right fit.
How do I stop worrying about climate change at night?
The goal is not to stop caring, but to stop ruminating. Practical strategies include setting a screen curfew 90 minutes before bed, writing your worries in a journal, and channelling anxiety into daytime action like volunteering or reducing your household footprint.
