Blue Light and Mental Health..
Nighttime exposure to blue light was linked to depressive symptoms in animal studies. But exposure to blue light during the day may have the opposite effect. It’s been used to treat seasonal affective disorder, or SAD. That’s a form of depression related to the changing of the seasons. Research shows 20 minutes of blue light exposure in the morning helps ease SAD symptoms.
