We all know that stress is bad for us because it can increase the risk of diseases and mental conditions. A new study found that stress might be responsible for increasing the risk of stroke and heart disease too. The study showed that people who have a higher activity in the area of the brain which is linked to stress, amygdala, might have a higher risk of stroke and heart disease.
The researchers who conducted this study found that the amygdala is tied to inflammation in the arteries and increased bone marrow. These two increase the risk of stroke and heart attack.
The researchers continue to explore the connection between stress and heart diseases and they discovered that the bone marrow produces extra white blood cells. The extra cells might cause the arteries to become inflamed or to develop plaques.
High blood pressure, smoking, and diabetes are also linked to higher risk of heart diseases but now stress might be another factor. Previous studies that were conducted on animals showed that stress is linked to higher activity in arteries and bone marrow.
Because the researchers were not sure if this applies to people too, they decided to conduct this study. Based on previous studies that showed that depression and anxiety trigger the amygdala, the researchers observed that this area in the brain is responsible for stress.
When that area of the brain is used too much and we are stress our chances of stroke and heart disease increase too. This is the first time a study showed that a part of the brain can be responsible for heart diseases. The research was completed with the help of 293 people. They took body and brain scans to see how stress affects their body.
The bone marrow, spleen activity, and their brain were tested before the study. The researchers were able to find a link between the area of the brain that is responsible for stress and the bone marrow activity.
The patients were tested for almost 4 years to see if there are any changes. The researchers observed that those who had higher amygdala activity had a higher chance of developing heart problems compared to those who had low amygdala activity. This study showed that stress can also be responsible for stroke and heart diseases.
