Walking This Long Lowers Heart Disease Risk by 300% (New Study of 33,000 People)

New research in 33,560 adults shows that walking in 15-minute bouts or longer reduces heart attack and stroke risk by nearly 300% compared to short walks.

00:00 — Study Overview: Walking Longer = Healthier Heart
Intro to new study: 33,000 participants, 9-year follow-up. Longer walks linked to lower cardiovascular mortality.

00:52 — Why Duration Matters (Not Just Step Count)
Many people walk but cut it short; duration of each walking bout is key for heart and circulatory health.

01:18 — Study Details & Categories
Published in Annals of Internal Medicine. Participants categorized into walking bout durations:

• <5 min

• 5–10 min

• 10–15 min

• ≥15 min

01:57 — Key Findings: Event Rate by Walking Duration
Cardiovascular event rate over 9 years:

• ≥15 min walks → 4.39% event rate

• <5 min walks → 13% event rate
  Almost 3× higher risk in the short-walking group.

03:02 — Breaking Down the Risk (Simple Numbers)
Clear, simplified comparison: 4 out of 100 (long walkers) vs. 13 out of 100 (short walkers). Duration literally slashes risk.

03:59 — Why Walking Works (and Why It’s Worth the Time)
Walking longer is one of the simplest, most accessible interventions to reduce cardiovascular disease risk.

05:00 — Practical Takeaways & Daily Strategy
Aim for ≥15-minute bouts; three 15-minute walks can outperform a single 45-minute session. “Walking is medicine.”
