Heart failure is becoming increasingly common, and doctors are sounding the alarm as more patients lose their lives to the condition each year. According to cardiologists, medical treatment alone is not enough — daily habits play a decisive role in whether heart failure worsens or stabilizes.

Experts emphasize that giving up certain habits can be difficult, but continuing them may significantly increase the risk of sudden deterioration or death.

1. Excessive Salt Consumption

High salt intake causes the body to retain water, increasing blood volume and placing extra strain on the heart. For people with or at risk of heart failure, this can lead to swelling, shortness of breath, and sudden worsening of symptoms. Doctors advise limiting salt and avoiding processed foods, instant meals, and salty snacks.

2. Staying Up Late and Chronic Lack of Sleep

Irregular sleep patterns and staying up late disrupt heart rhythm, raise blood pressure, and weaken the heart over time. Studies show that poor sleep significantly increases the risk of heart failure progression. Doctors recommend maintaining a consistent sleep schedule and ensuring adequate rest every night.

3. Smoking and Alcohol Consumption

Smoking damages blood vessels and reduces oxygen delivery to the heart, while alcohol weakens heart muscle and interferes with medications. Even small amounts can be dangerous for heart failure patients. Cardiologists stress that quitting smoking and limiting or completely avoiding alcohol can dramatically improve survival rates.

4. Physical Inactivity or Overexertion

Both extremes are harmful. Sitting too much weakens the heart and muscles, while sudden intense exercise can trigger dangerous cardiac events. Doctors recommend gentle, regular physical activity such as walking, stretching, or doctor-approved exercise plans tailored to individual conditions.

Warning Signs Not to Ignore

People should seek medical attention immediately if they experience:

• Persistent shortness of breath

• Rapid weight gain from fluid retention

• Swelling in the legs or abdomen

• Extreme fatigue or chest discomfort

The Bottom Line

Heart failure is serious, but it is not hopeless. Doctors stress that lifestyle changes can be just as important as medication. Giving up these four harmful habits — no matter how difficult — can significantly reduce the risk of complications and help patients live longer, more stable lives.
