Do humans have circadian rhythm?

Does the body make and keep its own circadian rhythms? Yes, natural factors in your body produce circadian rhythms. For humans, some of the most important genes in this process are the Period and Cryptochrome genes. These genes code for proteins that build up in the cell’s nucleus at night and lessen during the day.

Studies in cyanobacteria, however, changed our view of the clock mechanism, since it was found by Kondo and colleagues that these single-cell organisms could maintain accurate 24-hour timing in the absence of transcription, i.e. there was no requirement for a transcription-translation autoregulatory feedback loop for
