Sometimes the most powerful health advice is the simplest one. No expensive equipment, strict routine or complicated diet. Just one everyday habit that almost anyone can do. And the best part? It can actually add years to your life. A new video by Harvard-trained doctor Saurabh Sethi has shared a basic tip, which is so effective that you might feel surprised you’re not already doing it with more intention. It’s daily walking!
Walking: The Daily Habit That Can Change How Long You Live
In his video, Dr Sethi breaks down the science in clear words. He says, “This one daily habit can literally change how long you live and it is ridiculously simple.”
He points to a large study that tracked around 80,000 adults for nearly seven years. The findings were eye-opening. People who walked close to 10,000 steps per day had a significantly lower risk of dementia. Those who walked faster saw even stronger protection.
He also highlights another study that shows how every extra 2,000 steps a day may cut the risk of early death by around 10%. His message is that you don’t need extreme workouts to safeguard your health. Even small increases in daily activity create meaningful change over time.
Dr Sethi suggests practical ways to add more movement into your day. Take the stairs. Walk when you’re on calls. Keep a steady pace. And if you want to level up, he recommends intervals – three minutes fast and three minutes easy.
Why Walking Works So Well
Walking may seem too simple to offer major health benefits, but research shows the opposite. According to multiple studies published by the NIH and Harvard Health, regular walking supports better heart health, sharper memory, improved mood and stronger joints. It also reduces inflammation and helps regulate blood sugar levels. When done consistently, walking helps the body fight long-term risks linked to a sedentary lifestyle.
Experts say walking boosts blood circulation, improves oxygen flow to the brain and strengthens the muscles that support daily movement. Fast-paced walking offers even more advantages because it raises heart rate, helping the body burn energy more efficiently.
How You Can Start Today
The best part about walking is that you don’t need to wait. You can begin right where you are. A short walk after meals helps digestion. A walk in the morning clears the mind. Short breaks between work can refresh your focus.
You don’t always need to hit exactly 10,000 steps. What matters is consistency. Gradually increasing your step count can still protect your long-term health. Make it a habit you enjoy – listen to music, walk with a friend or explore a new route in your neighbourhood.
Walking is one of the simplest habits with the biggest returns. It doesn’t demand money or skill. It only asks for commitment.
