With depression becoming more and more prevalent, it's becoming increasingly important to understand what causes this condition in all its many forms. Simply put, however, the causes of depression aren't completely understood. There are a number of contributing factors that seem to increase the risk of developing depression, but exactly what determines who will experience depression and who won't under the same conditions isn't known.

Biology. There are a number of biological differences that may contribute to depression, including differing hormone levels and changes in certain brain chemicals. The Mayo Clinic explains, "The significance of these changes is still uncertain but may eventually help pinpoint causes." Among the brain chemicals most widely believed to be responsible for depression is the neurotransmitter serotonin, though others have been identified as potential contributors as well.

Genetics. Experts suspect there is a genetic component to depression, at least in some cases. If you have family members who have suffered from depression, you're at higher risk for developing depression yourself. However, it's uncertain as to whether the correlation is genetic in nature, or if it has to do with similarities in environment, health and habits. Some people may be more genetically prone to deficiencies of key neurotransmitters, or to other health issues that may also include depression.

Lifestyle. If you have a high-stress lifestyle—if you work too much, sleep too little, and aren't eating a healthy diet and getting enough exercise—then you may be at greater risk for developing depression. Proper self care is essential to overall well-being, including avoiding mental health issues such as depression. In addition, if your living environment has ever involved abuse or persistent conflict, especially in early childhood, then you may be more prone to depression even after those factors are no longer present. A lack of sufficient sunlight also causes depression in many people and is an ongoing concern for people who work long hours indoors or who live in areas such as Alaska and central or northern Canada where there may be very little sunlight during the winter months.
