It’s probably impossible to live a life that’s completely illness free. And, to quote another common phrase, nothing is certain but death and taxes – we humans aren’t designed to live forever.
If we’re lucky though, we’ll enjoy a decent innings. But while a long, healthy life is a blessing, it’s not entirely down to luck.
Some of the UK’s biggest killer diseases – heart disease, stroke, cancer, lung and liver disease – are, to a significant extent, preventable.
A major study published in The Lancet last year reported that the UK was falling behind other western countries in managing such illnesses, with the five conditions mentioned above responsible for more than 150,000 deaths in under-75s a year in England alone.
A fifth of these (30,000) are estimated to be avoidable.
It’s a cost issue too, with lifestyle-related diseases placing an ever-increasing burden on the NHS.
Diabetes costs the NHS £10billion a year (10% of its entire budget). While type 1 diabetes is not preventable, type 2, the form linked with lifestyle factors, is largely avoidable – and it’s this form which is costing the most, accounting for around 90% of the 3.2million people currently diagnosed with diabetes in the UK.
Coronary heart disease, the number-one killer causing 74,000 UK deaths a year, comes in at an annual cost of £2billion, and circulatory and heart diseases collectively (including stroke, heart attacks and cardiomyopathy) kill 161,000 a year, with an estimated overall bill of £19billion, for what are classed as premature deaths.
The risk factors for many of these conditions are well documented – smoking’s a huge health-zapper, and alcohol and a poor diet. Not getting enough regular exercise and being overweight or obese are also linked with an increased chance of serious long-term health problems.
Scientists are making huge strides in genetic research, and a number of genetic risk factors have been identified for many major diseases, but it could be a long time before these are unlocked entirely.
Meanwhile, what is certain is that lifestyle does play a role, enough of a role that it’s worth all of us taking steps to invest in our future health by looking after ourselves today.
“Sadly, for a lot of people, it’s the heart attack or the stroke that finally pushes them to stop smoking, whereas they’d have done a lot better to have stopped much earlier,” says the British Heart Foundation’s Dr Mike Knapton.
Professor Jeremy Pearson, the charity’s associate medical director for research, stresses the importance of raising awareness that arteries begin to narrow – the process that culminates in heart disease – years earlier.
“You don’t get a heart attack hopefully until you’re in your 50s through to your 70s, but this is a process that actually starts when you are very young,” he says.
Not smoking and not consuming too much alcohol are two of the main steps in having a healthy lifestyle.
Beyond that, eating well, taking regular exercise and managing stress effectively can all play a part in long-term health.
Three experts share their advice for getting started:
GET ACTIVE
“Staying active’s absolutely vital,” says osteopath and physiotherapist Tim Allardyce (www.surreyphysio.co.uk). “Everything in the body’s designed to move; joints, muscles, the blood that circulates, even our bowels.
“When you feel sluggish, listen to your body – get up, get your heart pumping. Next time you’re feeling tired, go for a short, brisk walk rather than having a nap.”
The benefits of exercise are practically boundless.
“It’s great for our cardiovascular system (the bit that helps us breathe and gets oxygen to our organs and muscles). It also helps our bowels stay healthy, keeps muscles strong and joints more flexible.
“Getting active is simple: exercise a little each day. Your weekly activity may not be going to the gym five times; instead go for three 20-minute walks, swim once a week, cycle every Sunday morning for an hour. After a few weeks, you’ll start to feel great.”
If you’ve been inactive for a while, start slowly, and speak with your doctor if you have existing health problems.
EAT A BALANCED DIET
“People are aware that a healthy diet can affect health, but I don’t think people generally understand just how essential it is,” says British Dietetic Association spokesperson Sioned Quirke, who has her own healthy eating website (www.quirkynutrition.co.uk). “Many people don’t like the idea of having to take medication, but don’t realise your diet and lifestyle is the most powerful drug of all.
“It’s very beneficial to have a variety of foods, including foods from each of the five food groups.”
There’s increasing evidence linking childhood diet to health consequences later in life. “It’s never too early to start getting into good habits,” adds Quirke. “Children learn from their parents – so if you have a healthy diet, so will they.
“Get children involved in food choices, knowing where foods come from and cooking early.”
BE STRESS AWARE
Stress is a normal fact of life. Our bodies react to challenging situations by triggering a “fight or flight” response, releasing chemicals, including adrenaline, to kick us into action. It’s only when chronic stress builds up that it becomes a health concern.
Managing stress, like eating well and being active, requires effort. “We often just continue on our daily treadmill, ignoring the little signs that our body provides us with, like sleeping difficulties, rapid heart rate, changes in eating habits and bowel movement,” says wellbeing expert Annie Aulds (www.wisteriaholistichealth.co.uk). “It’s only when our body makes the signs more obvious, like clinical depression or a heart attack, that it forces us to stop.
“It’s so important to listen to your body, understand its needs and act early while the symptoms are still self-manageable.”
