Something strange has been happening in Trinidad and Tobago.
Ask almost anyone how they are sleeping and the answer is rarely enthusiastic.
“I not sleeping good these days.”
It is said casually, often with a small shrug, as if poor sleep were simply another inconvenience of modern life. COVID exacerbated the situation.
When the same sentence is repeated across the globe, it becomes a public health signal.
Sleep is one of the most underestimated pillars of health. Doctors talk often about diet and exercise, about blood pressure and blood sugar, about cholesterol and medication.
Yet, sleep sits quietly beneath all of them, holding the system together. Without it, hormones drift out of rhythm. Appetite increases. Blood pressure rises. Mood becomes fragile. Concentration dissolves into a fog that coffee cannot quite clear.
Fatigue has become the background music of modern life.
The remarkable thing is that the body treats sleep deprivation as a form of stress.
Imagine the brain as a vigilant night watchman. When danger appears, the watchman rings a bell that alerts the entire system. Hormones surge. The heart beats faster. Muscles tense. The body prepares to respond.
This response is lifesaving when the threat is real and temporary. But what happens when the bell rings every night?
The watchman never rests.
Modern life has created an environment in which the nervous system rarely powers down. Long after sunset, screens glow in bedrooms and living rooms. Phones vibrate with messages, news alerts and social media notifications that demand attention.
There was a time when evening brought a gradual quieting of the world. Shops closed. Radios softened. Streets slowed. The body sensed the change in rhythm and followed it.
Today, the evening is simply an extension of the day.
Televisions argue loudly. Phones scroll endlessly. And just as sleep finally approaches, someone nearby decides it is the perfect moment to start a weed-whacker or a motorcycle that sounds like it is preparing for takeoff at Piarco.
Silence has become rare.
And the human brain notices.
Neuroscience tells us that sleep is not merely rest. It is maintenance. During deep sleep, the brain reorganises memories, clears metabolic waste, and resets hormonal systems that govern appetite, mood and immune function.
In other words, sleep is when the body repairs itself.
Take that away, and the consequences begin to appear quietly in the clinic.
Blood pressure that refuses to behave.
Blood sugar that creeps upward despite medication.
Patients who feel permanently tired yet strangely wired, as if the body is caught between exhaustion and alertness.
Doctors have begun to recognise that sleep deprivation is one of the hidden engines driving modern disease.
The relationship between sleep and metabolism is particularly striking. When people sleep poorly, levels of the hormone ghrelin rise, stimulating hunger. At the same time, leptin, the hormone that signals fullness, falls.
The result is predictable.
People eat more.
Usually not vegetables.
The body, deprived of restorative sleep, begins to crave quick energy—sugar, starch, caffeine.
Over time, this imbalance contributes to weight gain, insulin resistance, and eventually the conditions doctors spend their days trying to treat.
Hypertension.
Diabetes.
Obesity.
These illnesses often appear in clinics as separate diagnoses, but they frequently share a common thread.
The patient has not slept properly in years.
Doctors are not innocent in this story. Medicine has long glorified endurance. Generations of physicians trained under punishing schedules where sleeplessness was considered a rite of passage.
Some still wear those nights like medals.
“I worked 36 hours straight.”
It is a remarkable feat of survival.
But not necessarily a triumph of wisdom.
Modern medicine increasingly recognises that exhausted clinicians are more likely to make mistakes. Hospitals across the world are gradually reforming work schedules—not out of kindness, but because the science is undeniable.
Sleep protects judgement.
Anyone driving along the highway at six in the morning sees the evidence. Lines of red brake lights stretch into the distance while commuters sip coffee from paper cups and prepare for another long day before the sun has fully risen.
The day begins tired.
And ends the same way.
Of course, sleep is not being stolen by biology alone. It is also being stolen by the modern environment.
Stress is perhaps the most powerful thief.
A society under chronic stress does not sleep easily. Economic pressure, long commutes, family responsibilities, and the quiet background anxiety that accompanies crime and uncertainty all keep the nervous system on alert.
The brain interprets this alertness as danger.
Danger does not sleep.
And so the body remains ready.
Heart rate slightly elevated.
Breathing shallow.
Muscles tense.
The nervous system is locked in a low-grade fight-or-flight response that quietly erodes health over time.
The irony is that modern life often celebrates this state of exhaustion. Productivity becomes a badge of honour. People boast about surviving on four hours of sleep as if fatigue were proof of ambition.
But biology is unimpressed by bravado.
The body keeps meticulous records.
Eventually, it sends reminders.
The reminder may arrive as fatigue, irritability, headaches, or declining concentration. If those signals are ignored, the next message may appear in a laboratory report or a blood pressure reading.
Imagine a city that never maintained its roads or electrical grid. For a while, everything might appear functional. Then cracks would appear. Systems would fail.
The body behaves the same way.
Sleep is the nightly maintenance of the human system. Without it, the infrastructure deteriorates.
World Sleep Day is March 13th, with the theme “Sleep Well, Live Better.” It is fashionable to offer the usual advice: avoid caffeine late in the day, dim the lights, put away screens, meditate, breathe deeply and count sheep who appear to have excellent life balance.
The poet Thomas Dekker once wrote, “Sleep is that golden chain that ties health and our bodies together.”
Centuries later, neuroscience is merely confirming what poets already knew.
Sleep restores the mind, repairs the body, calms the heart and cleans the brain.
In a world addicted to speed, productivity and constant connection, sleep remains one of the few acts of quiet rebellion.
Perhaps the most radical health intervention available today is simply turning down that noise.
Let the nervous system remember what quiet feels like.
Give the body darkness.
Give it stillness.
Give it time.
A country that cannot sleep is a country that cannot heal.
And the first step toward recovery may be the simplest prescription medicine has ever offered.
Turn off the light.
Put the phone down.
Let the nervous system remember what silence feels like.
And rest.
