This Hobby Is Helping the Over Fifties Live 7 Years Longer, According to a New Study

As we get older, we’re all looking for that secret elixir to a longer life. We spend hundreds on gym memberships we never use, expensive supplements promising vitality, and all sorts of weird and wonderful diets in the hope of living longer. 

Now I don’t know about you, but as I get older, I want to spend more time enjoying my life, not constantly watching what I eat or putting myself through a treadmill workout. Well, it turns out I don’t have to.

A recent study revealed that one of the best ways to live a longer, healthier, and happier life is to spend more time gardening. And before you roll your eyes and say I’ve heard it all before, hear me out on this. Plus, I have a fun new tool to help you build your garden based on your space and fitness.

Why Gardening Helps You Live 7 Years Longer

Scientists followed 475 people for 25 years, tracking them from age 79 through their late eighties and into their nineties. They measured actual physical function, cognitive ability, and mortality over 2.5 decades.

The results were published in December 2024, making this one of the most recent and comprehensive studies on gardening and longevity.

People who gardened frequently had a 22% lower risk of death compared to those who rarely or never gardened. That held true even after researchers accounted for income, education, overall physical activity, and where people lived.

Not only did they live longer, but they also seemed to age better. At 79, they had stronger physical function, better mental wellbeing, and even longer telomeres (a biological marker of aging). As they moved through their eighties, they declined more slowly than non-gardeners. 

The Science in Simple Terms

Let me break down what researchers have found across multiple large studies:

Longevity: The Lothian Birth Cohort study found a 22% reduction in mortality risk for frequent gardeners. A separate study in Taiwan following over 5,000 adults found a 18% reduction in mortality.

Brain Health: The Dubbo Study in Australia tracked nearly 3,000 people aged 60 and older. Daily gardeners had a 36% lower risk of developing dementia. 

Purpose Adds Years: Research from Blue Zones (areas where people live past 100) shows that having a sense of purpose can add up to 7 years to your lifespan. In these communities, people gardened into their eighties and nineties.

Physical Function: A Swedish study of over 4,000 people aged 60+ found gardening reduced stroke risk by 27% and death from any cause by 30%.

Why Gardening Works So Well

Gardening gives you benefits across multiple areas that all contribute to longevity:

Your Brain Gets a Workout

Gardening is complex and requires planning in advance so you know what to plant, when to plant it, and where to plant it. You problem-solve when something goes wrong, remember watering schedules and plant care, and you’re learning names and growth patterns.

This isn’t like walking on a treadmill, where you repeat the same motion over and over again. Every time you step into your garden, you’re making decisions and noticing details, which helps keep your brain flexible and engaged.

Your Body Gets Functional Fitness

When you squat to pull weeds, you’re practicing the motion you need to get on and off chairs. When you carry watering cans, you’re building strength. When you reach overhead, you maintain flexibility for everyday tasks.

This is functional fitness, the kind that translates to real life. An hour of active gardening burns 300-400 calories, equivalent to a moderate gym session.

You get weight-bearing exercise (crucial for bone density), balance practice (prevents falls), and you work multiple muscle groups. All while enjoying the benefits of being in nature.

You Get a Reason to Get Up

This might be the most important part. When you have plants depending on you, you have something to do tomorrow, something that responds to your care.

In Okinawa, they call it ikigai, your reason for being. Having purpose is directly linked to living longer. Researchers estimate it adds up to 7 years to your lifespan. 

This makes perfect sense. I know that when I have days where I’ve got nothing planned, I feel restless and hate having no purpose. It’s huge for our well-being to have a purpose to our day. It’s one of the reasons why I don’t want to retire completely yet. I enjoy writing, and it doesn’t feel like work to me; it drives me each day and gives my day structure.

Additional Benefits

Sunlight exposure boosts vitamin D (most of us over 50 are deficient), although here in my part of France, we get approximately 2,200 hours of sunshine every year. There are bacteria in soil that naturally increase serotonin. If you grow your own food, you eat produce at peak nutritional value. Gardens create social connections with neighbors.
