A similar scenario may occur when eating and sleeping habits are out of sync with the body’s circadian clock, leading to metabolic disturbances. Over the past 20 years, scientists have assembled a clearer picture of the circadian clocks that keep human physiology tuned to the 24-hour ...
Resetting the Circadian Clock by Social Experience in Drosophila melanogaster, ArtículoCircadian clocks are influenced by social interactions in a variety of species, but little is known about the sensory mechanisms underlying these effects. We investigated whether social cues could reset circadian rhythms...
The circadian clock system (from Latin “circa diem,” about a day) allows the organisms to anticipate periodical changes of geophysical time, and to adjust to these changes. Nearly all the cells in our body comprise molecular clocks that regulate and synchronize metabolic functions to a 24-hour...
Reversible modulation of the circadian clock using chronophotopharmacology. Using light to interconvert two isomers of a photo-responsive small molecule, it is possible to pace cellular time. While irradiation with violet light extends the normal 24-hour clock to 28-hour, green light switches off ...
“Relaxed sleep schedules during the summer significantly distort the circadian rhythm in children," says Dr. Jared Heathman, a psychiatrist at Your Family Psychiatrist in Houston. “This results in difficulty returning to a normal sleep routine." If you're having trouble getting kids out of be...
Circadian clocks are self-sustained and cell-autonomous oscillators. They respond to various extracellular cues depending on the time-of-day and the signal intensity. Phase Transition Curves (PTCs) are instrumental in uncovering the full repertoire of re
Chronobiologyis the study of the relationship between biological rhythms and environmental cues. Currently under study are the use of light therapy and melatonin to reset the circadian rhythm. The bookChronotherapy: Resetting Your Inner Clock To Boost Mood, Alertness, and Quality Sleepdiscusses light ...

While genetics plays a role in these rhythms—for instance if your parents were night owls, it's likely you will be one too—environment, habits and lifestyles also affect the clock. "It's not just this free-running oscillator," said St. John. "It gets these inputs from light. For in...
