Sometimes, the desire to improve health takes the form of big, dramatic promises. Maybe every January 1, you vow to go to the gym every single day; no more pressing snooze on your alarm clock in the morning. Or, every once in a while, you get the urge to purge the pantry of anything ultraprocessed, recommitting yourself to a sugar-free diet.
Certainly, exercising every day and minimizing sugar are healthy habits to make, but dramatic changes can also be challenging to stick with. For most people, what’s more sustainable is making healthy changes in smaller steps instead of all at once. Committing to walking 20 minutes a day is the perfect example of this.

Instead of committing to strenuous workouts every day, going for a 20-minute walk is a more manageable goal. You don’t even need to change your clothes to do it. You can talk on the phone while you do it, calling a friend or family member who has been on your mind. 20 minutes is the length of roughly six songs and shorter than most podcast episodes.
Perhaps you’re skeptical about just how much a daily 20-minute walk can impact your health. The truth is, the benefits are greater than you likely think. Read on to find out what they are.

5 Things That Happen to Your Body When You Walk 20 Minutes a Day
1. It lowers your risk of cardiovascular disease
“Walking is amazing for your cardiovascular health,” says Allison Goldsmith, NASM, a certified personal trainer. Goldsmith explains that walking every day—even just for 20 minutes—strengthens the heart, which reduces the risk of high blood pressure and cardiovascular disease. “Walking enhances blood circulation, which improves overall blood flow. It also helps regulate blood pressure and decreases stress on the arteries,” she adds.
According to a scientific review published in Current Opinion in Cardiology, walking for 30 minutes a day, five days a week lowers the risk of heart disease by 19%. According to a scientific study that compared the benefits of running versus walking, both forms of cardio were similarly effective when it came to reducing the risk of high blood pressure, high cholesterol and diabetes. That means, if you can’t run or simply don’t like to, walking can be just as beneficial for your heart.

2. Walking supports brain health
It’s a safe bet that whatever is good for your heart is also good for your brain, and walking is no exception. “Walking increases blood flow, and blood contains oxygen. This means that more oxygen gets to the brain, which helps neurons function better. When neurons are functioning at optimal levels, your cognitive functions, like memory and attention, are enhanced. The blood even brings nutrients that decrease the risk of dementia,” Goldsmith explains.
Scientific research backs this up, showing that regular walking—especially at a quick pace—reduces the risk of dementia and Alzheimer’s. Even 3,800 steps a day can lower the risk by 25%.
Certified personal trainer Renee Moton, CPT, adds to this, saying that better blood flow to the brain also supports the immune system and the lymphatic system, which helps protect the body from infections. To this point, a study in the Journal of Sport and Health Science found that acute exercise, like walking, boosts the body’s defense system.
Moton also points out that walking supports mental health and is connected to lowering the risk of depression and anxiety. If you take a 20-minute walk in nature, you can bet that you’ll come back feeling more relaxed and happier than before you left the house.

3. Walking helps with blood sugar control
Both personal trainers say that a short walk can help with managing blood sugar, especially if it’s done after eating. “Taking a 10-minute walk after a meal within 60 minutes of eating reduces blood sugar spikes. When we walk, muscles consume glucose for energy, requiring less insulin and allowing for more stable glucose levels,” Goldsmith explains.
Scientific research shows this too, finding that walking can play an important role in managing type 2 diabetes.
4. It’s good for your bones and joints
While you may already know that strength training is important for supporting bone and joint health as we age, walking helps too. “Walking is a low-impact exercise that stimulates bone remodeling and helps with joint health. When your feet hit the ground, it lets the body know that your old bone tissue needs to be replaced to increase bone density and reduce the risk of fractures. Your hips and legs will receive the biggest benefits from walking, like increased bone mineral density,” Goldsmith says.
In terms of joint health, Goldsmith explains that joints don’t have much tissue, so it’s hard for them to receive the oxygen they need. But when you move your joints, such as by bending your knees when you walk, the heart sends blood flow to the knee joint. This, she explains, helps lubricate the joints as well as help circulate joint fluid, bringing nutrients to the cartilage.
While walking every day does support bone and joint health, Moton says that it’s important to strengthen the body, particularly the lower body, through other forms of exercise too. That way, the repetitive motion of walking won’t put too much wear and tear on the body.
5. Walking can add years to your life
Walking is so beneficial to health that it can literally add years to your life. Goldsmith points out that one of the common dominators in Blue Zones (regions in the world where people regularly live to be over 100 in good health) is that walking is integrated into residents’ daily routines.
According to one scientific study that took into account more than 17,000 women between the ages of 62 and 101, walking roughly 4,400 steps a day reduced mortality by an average of 41%—that’s huge!
If there was a medication that reduced mortality by 40%, lowered the risk of dementia as well as other chronic diseases like cardiovascular cancer, you’d want to take it every single day, right? Walking is free, accessible and enjoyable. It’s one of the easiest and most profound ways to support your health.
