Night light exposure is associated with greater odds of major depressive disorder, generalized anxiety disorder, PTSD, self-harm behavior, and psychotic experiences.

“Night light exposure associated w/greater odds of major depressive disorder, generalized anxiety disorder (GAD), (PTSD), self-harm behavior & psychotic experiences.”

“Independent of night-time light exposure, greater daytime light exposure was associated with reduced risk for major depressive disorder, PTSD, psychosis, and self-harm behavior.”

“The PTSD relationship based on nighttime light and The psychosis relationship based on daytime light those are the ones that really jumped out to me”

“one that greater light exposure in the day is associated with lower risk for psychiatric disorders”

“PTSD and self harm the more daytime light exposure ideally from sunlight because that's actually what's being measured in most cases we could talk about how we know that is going to approximately linearly draw drop the probability or the severity of these symptoms”

“and then the the inverse relationship right as light increases during the daytime you see this reduction in self harm”
