7 . You know that short walk to the shops and back? It’s about 10 minutes each way and you don’t know if you can be glad to make the trip, but that one short walk could save you from an early death, a new research by Cambridge University shows. In fact, as many as one in ten early deaths could be prevented if everyone managed at least half the recommended level of physical activity.
Risks of diseases such as heart disease, strokes(中风) — which were responsible for 17.9 million deaths in 2019 — and various cancers are all reduced with this simple short walk. This easy lifestyle change was also noted in an earlier study in January, 2023, so you really should give it a go.
By carrying out studies among a total of over 30 million participants, the latest Cambridge research found that just 75 minutes of exercise a week can reduce the risk of cancer by 7%. It was also enough to reduce the risk of developing cardiovascular(心血管的) disease by 17%.
Professor James Woodcock from the MRC Epidemiology Unit said, “We know that physical activity, such as walking or cycling, is good for you, especially if you feel it raises your heart rate. But what we’ve found is that there are many benefits to heart health and reducing your risk of cancer even if you can only manage 10 minutes every day.”
It goes without saying that doing the recommended 150 minutes per week is more beneficial than just 75 minutes. Around one in six early deaths would be prevented with the two plus hours of exercise, while 11% of cases of cardiovascular disease and 5% of cases of cancer would be avoided.
So what are you waiting for? Boots were made for walking.
