"Our findings suggest that using dim, cooler, lights in the evening and bright warmer lights in the day may be more beneficial," study lead, Dr. ![]() This indicates that we should be doing the opposite of what Night Shift does. The study's experiments confirm this, with blue colors producing weaker effects on the mice's circadian rhythm than (equally bright) yellow colors. Thus, our bodies are more likely to associate blue light with bed time. The logic behind the study, which is based on experiments performed on mice, is simple: we encounter more yellow light during the day (because, you know, the sun), while twilight is more blue.
