Artificial light and electronic devices like computers and televisions give our bodies false cues that have nothing to do with the natural order of things and disrupt our circadian rhythm, which a growing body of research has linked to many mental and physical health problems. Sleep issues are an obvious casualty, as is false hunger leading to overweight and obesity. Circadian rhythm disruption has also been implicated in high blood pressure and heart disease, cognitive dysfunction, neurological problems like Parkinson’s disease, asthma, autoimmune illness, and mental health issues like depression, seasonal affective disorder (SAD) and bipolar disorder.
