Exercise as a therapy for progressive diseases
By Mujahid Nasir Hussain
On 14 November 2025, the world marked World Diabetes Day, and a familiar message rang out across hospitals, communities, and workplaces: Africa must “know more and do more” to confront the rising tide of chronic diseases. It is a message that feels especially urgent here in Nigeria, and in cities like Kano, where the realities of modern life have dramatically reshaped how people live, move, work, and stay healthy. For many families, this year’s theme was not merely a global campaign. It reflected what they witness daily—more people living with diabetes, hypertension, kidney disease, stroke, obesity, and joint disorders than ever before.
The World Health Organisation has warned that Africa will soon face a dramatic shift in its health landscape. By 2030, deaths from non-communicable diseases are projected to surpass those from infectious diseases. This is a striking transformation for a continent historically burdened by malaria, tuberculosis, and HIV. Nigeria, Africa’s most populous nation, is at the centre of this shift, with cities such as Kano experiencing a rapid rise in chronic and progressive conditions. The reasons are both complex and straightforward: changing diets, prolonged sitting, stressful work environments, reduced physical activity, environmental pollution, and limited access to preventive healthcare.
Yet amid these alarming trends, one therapeutic tool stands out: exercise. For many years, exercise has been treated merely as a wellness activity or an optional lifestyle choice. But in reality, it is one of the most powerful and scientifically proven therapies for slowing the progression of chronic diseases. When the body moves consistently, it undergoes profound biological changes: insulin works better, blood vessels become healthier, the heart becomes stronger, inflammation decreases, and harmful fat around organs begins to shrink. These benefits are not cosmetic; they are therapeutic.
However, there is a critical truth that the public often misunderstands: exercise is powerful medicine, and like any medicine, it must be prescribed correctly. It is not something people with chronic diseases should “start doing” without guidance. The mode, frequency, intensity, and duration of exercise must be tailored to the individual’s medical condition, age, fitness level, and risk factors. What is safe and effective for one person may be dangerous for another. This is why professional guidance is so essential. For instance, a person living with uncontrolled hypertension should not begin intense aerobic workouts without clearance from a doctor, because sudden spikes in blood pressure could lead to complications.
Someone with diabetic neuropathy may not feel injuries in their feet, making certain activities unsafe without supervision. Individuals with chronic kidney disease need specific exercise prescriptions that do not strain the cardiovascular system or accelerate fatigue. People recovering from stroke require structured rehabilitation overseen by physiotherapists to prevent falls or further damage. Even patients with obesity, osteoarthritis, or long-standing back pain need tailored, gradual programs to avoid joint overload. This is why exercise should not be approached casually, especially in a context like Africa, where many chronic conditions are undiagnosed or poorly monitored. Before starting an exercise program, individuals living with progressive diseases should consult qualified professionals. Doctors provide medical clearance and identify risks. Physiotherapists design safe movements that protect joints and nerves. Exercise physiologists prescribe evidence-based routines that align with the patient’s goals and limitations. Their role is to ensure that exercise becomes therapy, not a trigger for complications.
In Kano State, this issue is especially relevant. The city has undergone a rapid transition from physically demanding lifestyles to sedentary routines. Many residents now spend long hours sitting in shops, riding motorcycles, or working in offices. Combined with high consumption of energy-dense foods and limited awareness of disease symptoms, progressive illnesses have become deeply entrenched. Yet awareness of safe, guided exercise therapy remains low. Many people begin rigorous routines abruptly, driven by social pressure or misinformation, only to injure themselves or exacerbate their conditions. Others avoid exercise entirely because they fear doing the wrong thing. Both extremes are harmful.
To confront this, a cultural shift is needed, one that recognises exercise as a vital part of medical care. Hospitals and clinics across Nigeria must integrate exercise counselling into routine visits, especially for patients with diabetes, hypertension, kidney issues, and obesity. Something as simple as a doctor explaining which movements are safe, or a physiotherapist demonstrating gentle routines, could prevent years of complications. Exercise physiologists, though still few in number, should be incorporated into more healthcare teams to design personalised programs grounded in scientific evidence.
At the community level, awareness must grow that exercise therapy is not a one-size-fits-all approach. It is a carefully structured health intervention. Encouraging early-morning walking groups, promoting workplace movement breaks, and organising community fitness sessions are valuable, but they must be paired with safety education. Leaders—traditional, religious, and educational—can play a vital role by emphasising the importance of seeking professional guidance before starting any intense routine, especially for those already living with chronic diseases.
It is also worth acknowledging the emotional dimension. People battling progressive diseases often feel overwhelmed, frightened, or uncertain. Exercise offers not just physical healing but a sense of agency. It improves mood, relieves anxiety, supports sleep, and helps people feel that they are actively shaping their health. This psychological benefit is powerful, especially in societies where chronic diseases still carry stigma. But again, confidence grows stronger when people know they are exercising safely and correctly under the guidance of trained professionals.
Nigeria’s future health outcomes depend on coordinated action. Families must embrace a culture of safe movement. Workplaces must reduce prolonged sitting and encourage healthy routines. Schools must restore physical activity as a normal part of the day, not an afterthought. Healthcare institutions must treat exercise as a formal therapy, not a casual suggestion. And individuals must understand that professional guidance is the foundation of safe and effective exercise therapy. The WHO’s projections are indeed alarming, but they are not destiny. Africa still has the opportunity to change its trajectory. But to do so, we must shift how we view health, how we integrate movement into daily life, and how we approach treatment of chronic diseases. Exercise will play a central role in this transformation, but only if it is approached with the same seriousness and medical supervision as any other form of therapy.
In the markets of Kano, the offices of Abuja, the streets of Lagos, and the rural communities of northern and southern Nigeria, the message must be clear: movement heals, but only when guided, intentional, and safe. The global call to “know more and do more” continues beyond 14 November. This is a reminder that Africans must not only embrace exercise as therapy but also do so with professional guidance to protect the body and preserve long-term health. Our path forward lies not just in treating disease, but in transforming lifestyles with knowledge, with care, and with the understanding that the right kind of movement, at the right intensity, prescribed by the right professional, can change the story of health for a generation.
