Heart failure affects at least 26 million people globally, and its prevalence is rising rapidly.

The condition doesn’t mean the heart has stopped, but that it pumps less effectively, depriving cells of oxygen-rich blood and causing fatigue, breathlessness, and chronic cough.

Over time, simple tasks like walking or climbing stairs become exhausting, yet with proper treatment and lifestyle changes, remission is possible.

Doctors warn that four common habits significantly contribute to heart failure and should be abandoned.

Excessive salt intake causes fluid retention and high blood pressure, weakening the heart over time—limit processed foods and cook with herbs instead.

A sedentary lifestyle also harms the heart; aim for 150 minutes of moderate exercise weekly and break up long sitting periods.

Smoking and heavy drinking damage blood vessels and heart muscle, so seek support to quit, while chronic stress and poor sleep raise cortisol and blood pressure—practice daily relaxation and aim for 7–9 hours of restful sleep.
