How strong is the evidence for Morning Light?

Evidence in this dataset relates mainly to the broader role of light exposure and circadian rhythms in health, including reviews on circadian regulation of metabolism and cardiovascular function, plus more specific research on evening light exposure (e-readers) impairing sleep and light therapy improving insomnia. That evidence is currently rated emerging (32/100), built on 6 published studies, including 1 meta-analysis -- still too little to draw firm conclusions from.
