I really do think walking is one of the most underrated things we can do for our health, wellbeing and mindset. It is free, simple, available to almost all of us, and yet the impact it has on our bodies and minds is extraordinary.
I walk every single day with the dogs, and some of my favourite moments are those early morning walks when the light is just coming up. There is something incredibly calming and grounding about being outside before the world gets too busy. The fresh air, the stillness, the birdsong and that first morning light make such a difference to how I feel for the rest of the day.
What is fascinating is that morning light is not just beautiful, it is genuinely important for our health. Getting outside in natural morning light helps regulate our circadian rhythm, which is our body clock. Researchers have found that exposure to bright natural light within an hour of waking improves sleep quality, supports earlier release of melatonin at night, and quietly lifts mood throughout the day. Morning sunlight also helps the body produce serotonin, one of our key feel-good chemicals, which later converts into melatonin to help us sleep properly at night. Walking adds to that effect, because physical activity in itself raises serotonin and lowers cortisol, the body’s main stress hormone.
The longevity science is even more remarkable.
A 2025 meta-analysis in The Lancet Public Health, led by Professor Melody Ding at the University of Sydney, pulled together 57 studies from more than ten countries including the UK and Australia. The findings are extraordinary. People walking around 7,000 steps a day had a 47 percent lower risk of dying from any cause, a 25 percent lower risk of cardiovascular disease, a 38 percent lower risk of dementia, a 22 percent lower risk of depression, a 14 percent lower risk of type 2 diabetes and a 28 percent lower risk of falls compared with those walking very little. Even 4,000 steps a day offers most of those gains. Ten thousand is not a magic number. Most of us simply need to move more than we currently do.
Brisk walking pace matters too. Research published in GeroScience found that people walking at a brisk pace had a 38 percent lower cardiovascular mortality risk in men and a 53 percent lower risk in women, compared with slower walkers. The pace at which you walk is almost as important as whether you walk at all.
For anybody thinking about weight, walking is far more powerful than it gets credit for.
A person of around 11 stone burns between 80 and 100 calories per mile at a moderate pace, and a heavier walker burns up to 130 calories per mile. Five brisk 30-minute walks a week can quietly burn 500 to 1,000 calories without you ever feeling like you are exercising. And it is not just about the scales. Multiple studies have shown that 30 to 60 minutes of brisk walking daily, sustained over 8 to 12 weeks, reduces visceral fat, the deeper belly fat wrapped around the organs that is most strongly linked to heart disease and type 2 diabetes. Many people see their waist circumference drop even when the number on the scales barely moves. That is real change.
Walking is also one of the best gentle ways to support strength and bone density as we get older.
Walking is a weight-bearing exercise, which means every step gently loads the skeleton and helps protect it. Research shows that regular walking does not necessarily build new bone, but it significantly slows bone loss, particularly in postmenopausal women, and it strengthens the muscles in the legs, core and lower back that support good posture and balance. The combination of walking with some simple resistance work, even just a few squats, calf raises and weighted carries at home, has been shown in research to increase bone mineral density at the spine and hip, which matters enormously as we age. Walking is the foundation. Strength work is the partner.
Walking releases endorphins and dopamine, helping reduce stress and anxiety while improving mood and clarity. I find that when life feels overwhelming or busy, going for a walk completely changes my perspective. Problems feel more manageable afterwards. Ideas seem to flow more easily. There is now a body of research showing that even a 20 minute walk in nature lowers cortisol, lifts mood, and quietly resets the nervous system. The same Lancet meta-analysis I mentioned above found a 22 percent reduction in depression risk among people who walked regularly.
Walking also supports brain health by increasing blood flow, oxygen and nutrients to the brain. Studies have shown it can support memory, concentration and even the growth of new neural connections in the hippocampus, the part of the brain most involved in memory and learning. A 38 percent lower risk of dementia in the Lancet data is not a small number. It is one of the biggest, simplest interventions we have.
One thing I found particularly interesting is that regular walkers tend to have fewer sick days, because walking increases the circulation of infection-fighting white blood cells and supports the immune system more broadly. It is rather lovely to think that something as simple as putting one foot in front of the other each day can have such a profound effect on our overall wellbeing.
We often think health has to involve huge changes, expensive memberships or complicated routines. Sometimes the most powerful things are the simplest. A daily walk, even a short one, can change how you feel physically, mentally and emotionally. It is one of the best forms of self care there is, and one of the few that asks for almost nothing in return.
So if you can, step outside today. Walk with a friend, your dog, your thoughts, your favourite podcast, or simply with the sunrise. Walk a little faster than feels comfortable. Walk to a slightly further coffee shop. Walk for the heart, the bones, the mood, the memory and the morning light. Your body and your mind will thank you for it.
