Even after researchers removed the humidity cycle, the insects continued following the established rhythm of moist and dry conditions. “They take humidity cues as a biological clock,” UC Professor Joshua Benoit said. The study, supported by grants from the National Institute of Allergy and Infectious Diseases, was published in the Nature journal Biological Timing and Sleep. Humidity can reset insects’ clocksCircadian rhythms are internal cycles that help regulate processes ranging from body temperature to hormone activity. Humans may sense it subtlyCould recurring humidity patterns also influence biological timing in mammals, including humans?
