Seasonal and circadian genetic variation charted across the human body

The daily rotation of Earth and its yearly voyage around the sun marks the natural rhythm of life on the planet. Human health indicators such as body temperature, blood pressure and sleep, as well as animal behavior including foraging, molting, mating or hibernating, is influenced by innate biological clocks that work over circadian (day-night and twenty-four hour) and/or circannual (seasons and twelve-month) cycles.
