Why Exercise Helps Depression

Exercise will help you by increasing BDNF and Neuritin, which are essential for stimulating neuronal growth in the hippocampus. However, similar to an antidepressant, the cell growth takes 6-8 weeks and because the BDNF only works on cells in the second stage of growth, it will take a few weeks to have an effect.

Similarly, you need to engage the cardiovascular system minimum 3 times per week, although the effects of exercise on increasing the size of the hippocampus are not necessarily linear (i.e. probably a half hour at least 3 times a week is minimum to see effects, busting your ass all week long can keep you fit but may not be the "magic switch").

Interestingly, consuming a high-fat diet has been shown to reverse the effects of early life stress in rats, which is shown to be linked to depressive symptoms later, but the effect is not compounded when paired with a high fat diet.

Several symptoms of depression are also correspondent with symptoms of autoimmune response during illness, such as IL-6 cytokines. That's why keeping healthy can lower depressive symptoms as well.

Clinical help is invaluable in the treatment of psychiatric disorders. Counseling can help you deal with the cognitive appraisals of your emotions whereas improving the physiological side of things may not be complete enough.

Many psychiatrists will not prescribe medication if they feel the depression can be dealt with in alternative ways and a central part of counselling is the follow-up. Every person is different and no advice you receive on the Internet or possibly even from a non-specialist can replace the suggestions of a trained counselor or psychiatrist.

Depending on where you live and based on the timing you mention in the onset, Seasonal Affective Disorder may be a factor in the severity of the depression. Exercise may help manage moderate depression throughout the year, but may not be enough during the winter months.
