Anxiety, along with many other mental illnesses, may be hereditary. If your parents or other family members tend to be nervous or on the edge, these traits could be passed down to you. It may also be a learned behavior from how your family handles stressful situations.
Prolonged stress plays a huge role in anxiety development. Whether it's your job, school, personal relationships, or financial status, everyday life takes a toll on you mentally.
Chemical imbalance in the brain
If you watch many commercials for anxiety or depression medication, there is a constant reference to having a chemical imbalance in the brain. This could be due to genetics or even your thoughts and actions. Various medicines can help in this situation.
A nutritious diet not only keeps people physically healthy, but also mentally healthy. Foods rich in B vitamins, especially B12, are considered "brain food." It's also recommended to avoid caffeine, as it can make you even more "jumpy" and "on the edge."
Lack of exercise
Regular exercise provides both physical and mental benefits. Physical activity releases endorphins, which are "feel good" chemicals. Exercise also helps you relieve built-up stress.
Anxiety disorders are known to be the No. 1 mental illness. There is not one particular cause of these disorders, but there are numerous factors that are believed be play key roles in their development.
