The study, published in the journal BMJ Open Sport and Exercise Medicine, was conducted by research teams from the CDC and the National Cancer Institute, among other organizations. They looked at data gathered on over 520,000 Americans, drawn from various studies ranging back to 2017, including the NIH-AARP Diet and Health Study. The researchers compared participants’ exercise habits against their Medicare (opens in new tab) claims over a series of decades. The data showed that those who began exercising in their 20s saved the most money on healthcare costs every year after retirement age, up to roughly $1,874 a year. The healthier you remain throughout adulthood, the less you’re likely to require prescription medicine too, reducing your potential Medicare Part D plan (opens in new tab) costs. Exercise was classed as walking or being active in day to day pursuits for a few hours most weeks. When commenting on the findings, the researchers said: “Our analyses suggest the healthcare cost burden in later life could be reduced through promotion efforts supporting physical activity participation throughout adulthood.” The key findings of the study showed that:
Healthcare costs in later life were significantly lower for adults who maintained moderate (saving $1,350 a year) or high physical activity levels ($1,200 a year).Adults who increased physical activity levels in early adulthood (saving $1,874 a year) or middle age ($824 a year) made bigger savings compared with adults who were consistently inactive from adolescence into middle age.
While this is just an observational study, and it has limitations, the results echo the findings of a 2015 study (opens in new tab) that estimated how inactivity among adults leads to over $100 billion in health care spending each year.
How a daily walk could lower your healthcare costs in later age
It’s never too late to begin exercising, so if you’re currently middle aged (around 45-65) or over and are pretty sedentary most days, now is the time to get moving. In the study, walking for a few hours every week was among the physical activities associated with lower healthcare costs, and even starting a daily walking routine in middle age can help you claw back some money on health care spending (up to $824) every year past retirement age. It might give you access to better health insurance companies (opens in new tab) too. Compared to something like running or cycling, walking is an accessible form of exercise for people who don’t have specific mobility requirements. Unless you plan on hitting the treadmill (opens in new tab) to get your daily steps up, you don’t need any special gear to do it either - just grab your sneakers and go.
How to start a walking routine
The WHO recommends (opens in new tab) all adults aged 18-64 to take part in at least 150-300 minutes of moderate intensity exercise each week, which could easily take the form of daily walks. There are plenty of online fitness programs (opens in new tab) that can help you start walking (and jogging, cycling or practicing yoga), and the majority state that when starting a new walking routine, begin with a short, daily work, as opposed to a longer walk just once a week. The health benefits of walking every day (opens in new tab) are plentiful, with recent research suggesting a 32% decrease in death among people who walked for at least 2,000 steps a day in uninterrupted bouts. Take it at a pace that suits you - you don’t have to start power-walking to reap the rewards of a daily stroll. The main thing is to move your body each day. We’d recommend setting a daily reminder on your phone or other device, and stick to your new schedule for at least 30 days in a row to cement your new walking habit. The Mayo Clinic has shared a 12-week walking schedule (opens in new tab) for adults aged 40 and over who are new to regular physical exercise, recommending that you start at a pace that suits you, “Then gradually pick up speed until you’re walking briskly — generally about 3 to 4 miles an hour. You should be breathing hard, but you should still be able to carry on a conversation.” Start off with a 15-minute walk during each day of week one, varying how fast or slow you walk within that 15-minute period, before extending it to 40 minutes during Week 12. “After you’ve tried the walking schedule for 12 weeks, aim to increase the time you’re walking briskly even more, from 30 to 60 minutes a day.”
