“Walking up 5 flights of stairs daily can cut down heart disease risk”

Several studies have found that walking 10,000 steps promotes good health. However, the findings of a new study have opened up new dimensions to how a good body can reap the benefits of walking.
A new study, led by researchers at Tulane University, suggests that taking at least 50 steps and rising stairs each day could significantly reduce your risk of heart disease.
This large cohort of UK adults demonstrated that climbing more than five flights of stairs daily was associated with over a 20% lower risk of ASCVD or atherosclerotic cardiovascular disease. “Participants who discontinued stair climbing between the baseline and resurvey exhibited a higher risk of ASCVD in comparison to those who never engaged in stair climbing,” the researchers have revealed in the journal Atherosclerosis.

What is ASCVD or atherosclerotic cardiovascular disease?

ASCVD along with coronary artery disease and stroke are the leading causes of morbidity and mortality worldwide.
ASCVD is a condition characterized by the buildup of fatty deposits, cholesterol, and inflammatory cells (atherosclerotic plaques) in the walls of arteries. These plaques can narrow and harden the arteries, limiting blood flow to the heart (coronary artery disease), brain (cerebrovascular disease), or other parts of the body.

It can lead to serious complications such as heart attacks, strokes, and peripheral artery disease. Risk factors include high blood pressure, high cholesterol, smoking, diabetes, and a sedentary lifestyle.

High-intensity stair climbing improves cardiovascular fitness

“Short bursts of high-intensity stair climbing are a time-efficient way to improve cardiorespiratory fitness and lipid profile, especially among those unable to achieve the current physical activity recommendations,” said co-corresponding author Dr Lu Qi, HCA Regents Distinguished Chair and professor at the Tulane University School of Public Health and Tropical Medicine.
“These findings highlight the potential advantages of stair climbing as a primary preventive measure for ASCVD in the general population.”

Data from 450,000 adults were studied

Using UK Biobank data collected from 450,000 adults, the study calculated participants’ susceptibility to cardiovascular disease based on family history, established risk factors and genetic risk factors and surveyed participants about their lifestyle habits and frequency of stair climbing. The median follow-up time was 12.5 years.
The study found that climbing more stairs daily, especially reduced the risk of cardiovascular disease in those who were less susceptible. However, Qi said the increased risk of heart disease in more susceptible people could be “effectively offset” by daily stair climbing.

Qi touted the public availability of stairs as a low-cost, accessible way to incorporate exercise into daily routines.
“This study provides novel evidence for the protective effects of stair climbing on the risk of ASCVD, particularly for individuals with multiple ASCVD risk factors,” Qi said.
