  • Atrial Fibrillation – This condition is caused by smoking which can lead to stroke and other cardiac issues.
  • Reduced Oxygen Supply – Smoking decreases the oxygen-carrying capacity of the blood. This makes the heart work harder and pump blood to deliver oxygen to the body.

Depression and Anxiety

The bond between mental health and heart health is complex and not understood completely. Continued depression and anxiety can lead to develop progression to cardio diseases.

Lack of physical activity

Poor blood circulation – It is a known fact that regular exercise promotes blood circulation. Blood is the medium to carry all required nutrients throughout the system and helping to pump it better is essential for the heart to work efficiently.
