The biologic clock in humans; the rhythmic repetition of certain phenomena, such as hunger, fatigue, and changes in blood pressure, that tend to fluctuate within a 24-hour period.
The fixed pattern of changes in basic body processes during a 24-h period.
Physical biorhythms affecting events including body temperature, endocrine function, and sleep cycle.
The occurrence of biological processes in cycles of about 24 hours. Circadian rhythm is determined by a “biological clock” that is set to coincide with recurring daily cycles of light and darkness. Biological processes that occur according to circadian rhythm include hormone secretion, sleeping, eating, and sensitivity to d rugs and stimuli.
Diverse yet predictable changes in physiological variables, including sleep, appetite, temperature, and hormone secretion, over a 24-hr period.
The body’s internal system for regulating sleeping and waking patterns.
A 24-hour cycle of behavior patterns that some living things, including humans, exhibit.
The 24-hour biological! cycle linked to the light dark cycle that regulates one’s internal physiological processes.
Referring to any intrinsic biological rhythm inherent to an organism, characterized by a recurring pattern lasting approximately 24 hours. In humans, this term is frequently employed to describe the cycle of sleep and wakefulness.
A circadian rhythm refers to any recurring pattern of physiological functions that follows a roughly 24-hour cycle. It is also known as a diurnal rhythm. A notable example of this pattern is the daily cycle of sleep and wakefulness.
