Female rhesus monkeys of different ages were studied during Epitalon-related hormone assessments.
What the researchers measured
Melatonin and cortisol secretion were measured by immunoassay, including time-of-day patterns.
How to read this evidence
Researchers studied cells, isolated tissue, or animals. These experiments can help explain a mechanism, but do not establish benefits or safety in people. Human cells grown in a laboratory also belong in this category.
Results in context
The report concerns hormone rhythms in nonhuman primates. It does not establish improved sleep or anti-aging outcomes in people.
What this does not establish
A nonhuman primate hormone study does not establish human sleep improvement or longevity.
