Why exercise is no longer a luxury

The transformation in our lifestyle has been accompanied by another, less welcome change: the increasing prevalence of conditions such as obesity, diabetes, hypertension and abnormal cholesterol levels. These diseases were once considered mainly problems of later life.
Today, however, they are increasingly seen among younger adults and even children.
This raises an important question: Are we giving our bodies enough opportunity to do what they were designed to do?
The human body was built for movement. Exercise is not simply a way to lose weight or improve appearance; it is an essential component of maintaining health throughout life. Finding time for physically challenging activity — even within an extremely busy schedule — can have profound benefits.
The good news is that exercise does not have to mean spending hours in a gym or becoming an elite athlete. Walking, cycling, swimming, jogging, playing a sport, climbing stairs or performing appropriately selected resistance exercises can all contribute to a healthier body.
The most important factor is finding an activity that is appropriate for the individual’s age, physical ability and health status — and doing it consistently.
Regular physical activity has been associated with a lower risk of numerous chronic diseases, including type 2 diabetes, hypertension, abnormal cholesterol levels, coronary artery disease and stroke. It also plays an important role in maintaining bone strength and reducing the risk of osteoporosis.
But the benefits of exercise extend far beyond the heart, blood vessels and muscles. The brain also benefits from movement. Research has increasingly demonstrated a strong relationship between physical activity and mental health.
Exercise can improve mood, reduce symptoms of anxiety and depression, and enhance overall psychological wellbeing. Evidence from clinical studies has even suggested that structured exercise can have meaningful therapeutic effects in people with mild to moderate depression.
Physical activity stimulates complex interactions between the brain, nervous system and the rest of the body. During and after exercise, several neurochemical processes occur that can influence mood, stress and cognitive function. Exercise also strengthens the connection between the brain and muscles, improving coordination and the body’s ability to respond to physical and psychological challenges.
There is another important benefit that is sometimes overlooked: sleep. Regular physical activity can contribute to better sleep quality, allowing the body and brain to recover. During sleep, the body performs essential processes involved in tissue repair, memory consolidation and restoration. Exercise and sleep therefore form an important partnership in maintaining health.
When discussing exercise, we should also move beyond the traditional idea that cardiovascular or 'aerobic' exercise is all that matters. A balanced exercise programme should also include resistance training. This does not necessarily mean lifting heavy weights. Resistance can come from body weight, resistance bands, machines, light weights or even appropriately assisted exercises.
Resistance exercise becomes particularly important as we grow older. With ageing, muscle mass and strength naturally decline. This can affect balance, mobility and independence and increase the risk of falls.
Maintaining muscle strength through regular resistance exercise can help preserve functional capacity and reduce the consequences of falls and physical frailty.
There has been considerable debate about whether morning, afternoon or evening exercise is best. In reality, the best time is often the time you can consistently dedicate to it. A workout at a convenient time is far better than an ideal workout that never happens. For those who exercise later in the evening, however, it may be sensible to avoid very strenuous exercise immediately before bedtime, particularly if it interferes with relaxation or sleep.
Perhaps the most important message is that a healthy lifestyle should not be treated as a short-term project. Health is not a challenge that we complete for a few weeks before returning to our previous habits. It is a way of living.
Food, physical activity, sleep, stress management and other daily habits all contribute to our health. None of them works in isolation. Instead, small and sustainable improvements across several areas can eventually produce a remarkably large difference.
We can start by walking more, taking the stairs, spending less time sitting, exercising regularly and gradually incorporating resistance training into our routine. We can make better food choices and protect our sleep. Most importantly, we can make these changes sustainable rather than extreme.
In our increasingly busy world, finding time for ourselves can sometimes feel like a luxury. But investing time in health is not a luxury — and it should not be considered a privilege reserved for those who have fewer responsibilities.
Our health is the foundation that allows us to work, care for our families, enjoy our lives and age with dignity and independence. We may not be able to slow down the modern world, but we can choose to keep our bodies moving within it.
