The cause of depression is not entirely clear. However, it's believed that both genetic and environmental factors, such as stress, may play a role.
Some people are more vulnerable to stress because of their personality characteristics or temperament. Persistent or chronic stress has the potential to put vulnerable individuals at a substantially increased risk of depression, anxiety and many other emotional difficulties. Scientists have noted that changes in brain function — in the areas of the hypothalamus and the pituitary gland — may play a key role in stress-induced emotional problems.
Many factors contribute to maintaining good mental health, including getting enough sleep, eating sensibly, exercising appropriately, avoiding use of harmful substances such as alcohol, and effectively managing stress. If you have chronic stress, consult a doctor or therapist to discuss ways to minimize stress and its negative impact on your physical and emotional health. He or she may recommend relaxation exercises, such as deep breathing or visualization, soothing activities, such as yoga or massage, or professional therapy.
