Blue light exposure and the importance of darkness at night as it related to depression
In the modern world, there is an evolutionary mismatch concerning light exposure. Many people are indoors during the daytime where they are not exposed to bright light, while artificial lighting allows light exposure during the night. Light exposure is essential for entraining a variety of bodily rhythms such as cortisol release and cytokine production. Moreover, research shows that bright light therapy is helpful in the treatment of non-seasonal depression. In this clip, Dr. Charles Raison discusses how exposure to light during the day and maintaining a dark environment at night is important in depression management.
