1. Blood Vessels
Issues with blood vessels can be dangerous for the heart. The flow of blood in the vessels is reduced if one suffers from high blood pressure. If that happens, the vessels contract and they also become brittle. This causes damages to the vessels and as a result, they can’t carry enough oxygen and nutrients to the tissues and cells. This can turn out to be fatal.
Note: A bad mood is common and it does not necessarily mean depression or a mental disorder. Having said that, if you experience depression symptoms, we strongly recommend you consult a doctor.
