Biorhythm may refer to:
Chronobiology is a field of biology that examines timing processes, including periodic (cyclic) phenomena in living organisms, such as their adaptation to solar- and lunar-related rhythms. These cycles are known as biological rhythms. Chronobiology comes from the ancient Greek χρόνος, and biology, which pertains to the study, or science, of life. The related terms chronomics and chronome have been used in some cases to describe either the molecular mechanisms involved in chronobiological phenomena or the more quantitative aspects of chronobiology, particularly where comparison of cycles between organisms is required.
The biorhythm theory is the pseudoscientific idea that peoples' daily lives are significantly affected by rhythmic cycles with periods of exactly 23, 28 and 33 days, typically a 23-day physical cycle, a 28-day emotional cycle, and a 33-day intellectual cycle. The idea was developed by Wilhelm Fliess in the late 19th century, and was popularized in the United States in the late 1970s. The proposal has been independently tested and, consistently, no validity for it has been found.
Delayed sleep phase disorder (DSPD), more often known as delayed sleep phase syndrome and also as delayed sleep–wake phase disorder, is the delaying of a person's circadian rhythm compared to those of societal norms. The disorder affects the timing of biological rhythms including sleep, peak period of alertness, core body temperature, and hormonal cycles.
Bases Loaded II: Second Season, known in Japan as Moero!! Pro Yakyū '88 Kettei Ban, is a video game for the Nintendo Entertainment System released in 1988. It is the sequel to Bases Loaded and is continued by Bases Loaded 3. The game is the second installment of the Bases Loaded series. The game was novelized by Peter Lerangis, as part of the Worlds of Power series published by Scholastic Books.
Claudio Stampi is the founder, director and sole proprietor of the Chronobiology Research Institute which he runs from his home in Newton, Massachusetts, US. He is an academic sleep-researcher with a particular interest in the use of short naps in extreme conditions.
Wilhelm Fliess was a German otolaryngologist who practised in Berlin. He developed the pseudoscientific theory of human biorhythms and a possible nasogenital connection that have not been accepted by modern scientists. He is today best remembered for his close friendship and theoretical collaboration with Sigmund Freud, a controversial chapter in the history of psychoanalysis.
Konopka is a Polish surname. People with this name include:

Franz Halberg was a scientist and one of the founders of modern chronobiology. He first began his experiments in the 1940s and later founded the Chronobiology Laboratories at the University of Minnesota. Halberg published many papers also in the serials of the History Commission of International Association of Geomagnetism and Aeronomy. He also published in "Wege zur Wissenschaft, Pathways to Science". He was a member of many international bodies, was awarded five honorary doctorates and was a member of the Leibniz Sozietät der Wissenschaften zu Berlin. In the 1950s, he introduced the word circadian, which derives from the Latin about (circa) a day (diem).

Van Hasselt is a Dutch-language toponymic surname, meaning "from Hasselt", a town either in Belgian Limburg, Dutch Limburg, Overijssel, the District of Kleve, or East Frisia. Notable people with this surname include the following:
A chronotype is the behavioral manifestation of underlying circadian rhythm's myriad of physical processes. A person's chronotype is the propensity for the individual to sleep at a particular time during a 24-hour period. Eveningness and morningness are the two extremes with most individuals having some flexibility in the timing of their sleep period. However, across development there are changes in the propensity of the sleep period with pre-pubescent children preferring an advanced sleep period, adolescents preferring a delayed sleep period and many elderly preferring an advanced sleep period.
Chronobiology International is a peer-reviewed scientific journal that covers all aspects of biological and medical rhythm research, chronotherapeutics, and chronoprevention of risks. It is the official journal of the International Society for Chronobiology, the American Association for Medical Chronobiology and Chronotherapeutics, and the Society for Light Treatment and Biological Rhythms. According to the Journal Citation Reports, the journal has a current impact factor of 2.562 (2018).

"Caramel" is a song by Blur, the tenth track on their 1999 album 13.
The morningness–eveningness questionnaire (MEQ) is a self-assessment questionnaire developed by researchers James A. Horne and Olov Östberg in 1976. Its main purpose is to measure whether a person's circadian rhythm produces peak alertness in the morning, in the evening, or in between. The original study showed that the subjective time of peak alertness correlates with the time of peak body temperature; morning types have an earlier temperature peak than evening types, with intermediate types having temperature peaks between the morning and evening chronotype groups. The MEQ is widely used in psychological and medical research and has been professionally cited more than 4,000 times.
Till Roenneberg is a professor of chronobiology at the Institute of Medical Psychology at Ludwig-Maximilian University (LMU) in Munich, Germany. Roenneberg, in collaboration with Martha Merrow, explores the impact of light on human circadian rhythms, focusing on aspects such as chronotypes and social jet lag in relation to health benefits.
Martha Merrow is an American chronobiologist. She currently chairs the Institute of Medical Psychology at the Ludwig Maximilian University of Munich. Her career focuses primarily on investigating the molecular and genetic mechanisms of the circadian clock. Since joining the Ludwig Maximilian University in 1996, Merrow has investigated molecular and genetic mechanisms of the circadian clock as well as daily human behavior and medical psychology.
The Hunza cuisine also called the Burusho cuisine consists of a series of selective food and drink intake practiced by the Burusho people of northern Pakistan that is argued by some to be unique and have long lasting effects. The diet mostly consists of raw food including nuts, fresh vegetables, dry vegetables, mint, fruits and seeds added with yogurt. The cooked meal, daal included with chappati, is included for dinner. It has also been advocated for being inexpensive and mostly self-producible. The Hunza lifestyle was referenced in the Biorhythm Calendar published by the American Health Institute in the later 1970s.
Achim Kramer is a German chronobiologist and biochemist. He is the current head of Chronobiology at Charité – Universitätsmedizin Berlin in Berlin, Germany.
