How do you avoid depression in winter due to the extended darkness? - winter depression more condition_symptoms

I am a student in the north, and I am very depressed when winter comes because of the long darkness. I live, where there are only 4 hours of the day in the middle of winter (I'm in Norway). Those who had experienced a winter in recent years, was terrible. Now I have to avoid depression. There is someone there who can tell me how to avoid or reduce depression?
Thank you.
