Nutrición Hospitalaria, 2013 Chronobiology is a word derived from three Greek stems: kronos for time, bios for life and logos for study. From microarrays studies, now it is accepted that 10-30% of the human genome is under the control of circadian molecular clocks. This implies that

Chronobiology and mood disorders
Dialogues in Clinical Neuroscience, 2003 The clinical observations of diurnal variation of mood and early morning awakening in depression have been incorporated into established diagnostic systems, as has the seasonal modifier defining winter depression (seasonal affective disorder, SAD). Many circadian rhythms measured in depressive patients are abnormal: earlier in timing, diminished in ...

Chronobiology and nutrition [PDF]
Neuroscience, 2013 Numerous long-term studies have investigated the circadian clock system in mammals, which organizes physiological functions, including metabolism, digestion, and absorption of food, and energy expenditure. Food or nutrition can be a synchronizer for the circadian clock systems, as potent as the external light-dark signal can be.

Psychiatria Danubina, 2021 Seasonal fluctuations in mood, drive, energy, sleeping- and eating behavior, weight, as well as further important mental and physical functions, and the utilization of light as an effective treatment option were already described by Hippocrates of Kos and Araeteus, the Cappadocian.

Chronobiology and Chronotherapy of Osteoporosis [PDF]
JBMR Plus, 2021 ABSTRACTPhysiological circadian (ie, 24‐hour) rhythms are critical for bone health. Animal studies have shown that genes involved in the intrinsic molecular clock demonstrate potent circadian expression patterns in bone and that genetic disruption of these clock genes results in a disturbed bone structure and quality.

Chronobiology by moonlight [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2013 Most studies in chronobiology focus on solar cycles (daily and annual). Moonlight and the lunar cycle received considerably less attention by chronobiologists. An exception are rhythms in intertidal species. Terrestrial ecologists long ago acknowledged the effects of moonlight on predation success, and consequently on predation risk, foraging behaviour

Chronobiology and Anesthesia [PDF]
Anesthesiology, 2004 CHRONOBIOLOGY investigates biologic rhythms that are involved in the organization of living organisms. Biologic rhythms consist of variations of biologic phenomena that are periodic and foreseeable in time. They are genetically determined as indicated by their persistence during constant conditions such as continuous light or darkness.

Introduction to Chronobiology [PDF]
Cold Spring Harbor Perspectives in Biology, 2017 A diverse range of species, from cyanobacteria to humans, evolved endogenous biological clocks that allow for the anticipation of daily variations in light and temperature. The ability to anticipate regular environmental rhythms promotes optimal performance and survival.

Clocks & Sleep, 2023 It is well known that variations in light exposure during the day affect light sensitivity in the evening. More daylight reduces sensitivity, and less daylight increases it.
