Taken together, our results indicate: 1) levels of melatonin and of creatinine-corrected 6-OHMS in the first morning void urine are strongly correlated with total nocturnal plasma melatonin output (P < 0.001) and also with peak nocturnal melatonin values (P < 0.001); 2) similar ranges for 6-OHMS were found in the laboratory and the field; and 3 . Morning light triggers the body to stop producing melatonin and increase alertness. Alcohol notoriously causes rebound anxiety and 3am awakenings for many people. The levels of saliva cortisol and MT were measured by enzyme-linked immunosorbent assay method. An increased melatonin level makes waking up in the morning difficult.
