Exercising throughout adulthood can cut the risk of early death by 30 to 40 per cent, a study has found.
While long-term good habits reap the most benefits, researchers say that switching to a more active lifestyle at any point in adulthood can extend longevity, suggesting it is never too late to embrace healthier habits.
The research, published in the British Journal of Sports Medicine, reviewed 85 existing studies involving millions of individuals and found that overall, physically active people are less likely to die from a range of conditions, including heart disease, stroke and cancer.
The findings highlighted that those who maintained consistent physical activity enjoyed a 30 to 40 per cent lower risk of dying from any cause, while individuals who increased their exercise levels, even from previously low amounts, still saw a notable 20 to 25 per cent lower risk.
Notably, people who switched from being physically inactive to being active were 22 per cent less likely to die from any cause than those who remained inactive.
The team, including experts from the University of Queensland in Australia, wrote: “Several mechanisms may explain the reduced mortality risk with high physical activity, such as physical function improvement and anti-inflammatory effects.”
They said their results “emphasised the importance of physical activity across adulthood, indicating that initiating physical activity at any point in adulthood may provide survival benefits”.
Currently, the World Health Organisation (WHO) recommends adults aim for 150 to 300 minutes per week of moderate-intensity physical activity, or 75 to 150min per week of vigorous-intensity activity, or a combination of the two.
Examples of moderate activity include very brisk walking (4mph or faster), heavy cleaning such as washing windows or mopping, cycling at 10mph-12mph, or badminton.
Vigorous activity includes hiking, jogging at 6mph or faster, shovelling, fast cycling, a football game, basketball or tennis.
Cancer Research UK health information manager, Amy Hirst, said that “by helping you keep a healthy weight, it can reduce the risk of 13 different types of cancer”.
“Any exercise is better than none, and the more you do, the better. You don’t need to run a marathon or join a gym – anything that gets you warmer, slightly out of breath, and your heart beating faster counts.
“So, whether you go for a brisk walk, a cycle with a friend, or even get the housework done, these all count as ways to be active. Think about making small changes to your daily routine – it all adds up and helps you get moving more.”
June Davison, senior cardiac nurse at the British Heart Foundation, said the review “suggests that being consistently active is associated with a reduction in deaths from any cause”.
“It suggests it is never too late to get active, as switching to a more active lifestyle at any point in adulthood has health benefits, such as reducing the risk of death from cardiovascular disease. To keep your heart healthy, adults should aim to be active every day, building up to a total of 150 minutes of moderate-intensity activity every week.
“Simple everyday activities, like a brisk 10-minute walk during your lunch break, all count.”
Sport England chief executive Tim Hollingsworth said: “Doing something will always be better than doing nothing, and – as is rightly stated – it is also never too late to start.
“The report reaffirms that being physically active should be championed at every turn by decision-makers for the good of our health, communities, economy and country.”
Huw Edwards, chief executive of ukactive, said: “This study provides clear evidence that switching to an active lifestyle, at any life stage, has a drastic impact on prolonging life.
