Your Body Keeps the Score and Your Job Is Writing the Bill

There is a particular kind of tired that has nothing to do with how long you slept.

You know that type of tired right ? The type that you wake up after seven hours and still feel heavy, the kind of exhaustion that sits behind your eyes and follows you to the office, through the meetings, past the deadlines and all the way back home where you sit on the bed still in your work clothes wondering why you feel like you ran a marathon when all you did was sit at a desk for eight hours and worry about things.

That is work stress, and it is doing considerably more damage than most people realise.

Two thirds of employees globally reported feeling burned out in some way in the past year, according to Mind Share Partners' 2025 research, and the economic cost of that burnout is staggering, Gallup estimated that diminished productivity from poor employee wellbeing drained $438 billion from the global economy in 2024 alone, a number so large it stops feeling real until you consider what it actually represents, which is millions of people showing up to work every day carrying a weight that is quietly making everything harder.

In Nigeria the picture is its own specific kind of difficult.

Research published in Frontiers Public Health in 2026 studying workplace stress among Nigerian academics found that work overload was the leading productivity-related stressor, while inadequate pay ranked highest among job satisfaction stressors, and anyone who has worked in a Nigerian office, formal sector or otherwise, in the last two years understands intuitively why those two findings land the way they do, because the combination of being asked to do more than is reasonable while being paid less than is fair in an economy where the cost of everything keeps rising is not a recipe for wellbeing, it is a recipe for the kind of chronic stress that the body eventually runs out of ways to absorb.

Prolonged work stress is now firmly linked to hypertension, diabetes, depression and a broader non-communicable disease burden, according to the same research, which means the headache you have been dismissing as just stress and the elevated blood pressure your doctor mentioned at your last check-up and the weight you cannot seem to shift regardless of what you eat are not separate unrelated problems, they are the same conversation happening in different parts of your body simultaneously.

So what do you do about it ?

The answer that research keeps returning to, across studies, across populations and across every income level, is movement, not rest, not avoidance, not scrolling through your phone until 1am hoping the anxiety settles on its own, but deliberate physical exercise, and the reason it works is not motivational, it is biological.

When you exercise your body releases endorphins, the brain's natural mood elevators, while simultaneously reducing cortisol, the primary stress hormone that your body produces when it perceives threat, and the combination of more endorphins and less cortisol is essentially the opposite of what chronic work stress produces, which is why a 30-minute walk, a gym session, a quick run or even a vigorous workout at home can change the chemical environment of your brain more reliably than almost anything else available to you without a prescription.

Research from the University of Nigeria Nsukka published in 2025 confirmed a significant relationship between exercise intensity and mental health among Nigerian students, finding that regular physical activity improved mental health outcomes even in high-stress academic environments, and the findings align with decades of global research showing that people who exercise regularly report lower levels of anxiety, better sleep quality, improved concentration and greater resilience to the kind of everyday stressors that accumulate into something serious when they have nowhere to go.

The challenge for most Nigerian professionals is not knowledge, it is time, or more accurately the feeling that time for exercise does not exist in a life already stretched thin between work, commute, family and the general administrative burden of surviving daily life in a Nigerian city, and that feeling is understandable and also slightly misleading, because the research does not require you to become an athlete or spend two hours in a gym to see meaningful results.

Thirty minutes of moderate exercise five days a week is enough to produce measurable improvements in stress levels, mood and physical health markers according to the World Health Organisation's physical activity guidelines, and moderate means a brisk walk, a light jog, a cycling session or any activity that raises your heart rate and keeps it elevated for the duration, none of which requires expensive equipment or a gym membership or time you do not have.

The question is not really work stress versus exercise, as though the two are in competition, the question is whether you are giving your body any way to process and release the stress that work is generating, and if the answer is no then the stress does not disappear, it simply accumulates, quietly and persistently, until the body finds its own way of forcing the conversation.
