For as long as humans have looked upward, the full moon has carried the weight of blame for restless nights and frayed nerves. Now, science is beginning to take that ancient suspicion seriously, finding modest but measurable disruptions to sleep duration and melatonin levels during lunar peaks — though the picture remains incomplete, shaped as much by individual biology and research bias as by moonlight itself. The moon, it seems, may indeed whisper to our circadian rhythms, but whether we hear it depends on who we are.

Scientific authority framing with emphasis on measurable findings. Uses 'what science says' approach to legitimize popular belief, but acknowledges inconclusive nature. Leads with surprising/compelling study results.
sorprendieron a muchos científicos (surprised many scientists) - implies unexpectedness
lunáticos (lunatics) - colloquial term playing on lunar etymology
rotunda (emphatic/definitive) - suggests stronger conclusions than evidence supports

Minimal direct impact. If validated, could increase demand for sleep aids, white noise machines, and sleep tracking devices among affected consumers, but effect size (20-30 min sleep reduction) is modest and affects subset of population.
Low likelihood of policy response given inconclusive evidence. Potential future workplace accommodation discussions if sleep disruption becomes established fact, but currently insufficient scientific consensus for regulatory action.
