In fact, melatonin production peaks around age 5 and starts a downhill slide from there. Unfortunately, we lose up to 80 percent of those original levels by the time we reach 60. And that's likely one of the reasons we don't sleep as well when we get older. When you're 20 and can easily sleep until noon, your levels of melatonin average about 80 picograms per milliliter; at 60, those levels drop down to 10. At age 20 you might have had a level of 10 in the late afternoon.
As expected, circulating melatonin levels were lower in night shift workers compared to day shift workers. When evaluated by chronotype, however, the authors found that morning-type night shift workers were better able to maintain normal melatonin levels than evening-type night shift workers. These differences in the effect of chronotype were statistically significant in every instance (P-interaction < 0.01).
