There are many types of biological rhythms
governing the bodies of living beings, including the frequency domain, which can be classified into ultradian, circadian, and infradian rhythms .
Emerging science reveals that each of us has an optimal time to fall asleep and wake up, a personalised biological rhythm
known as a "chronotype." When you don't sleep at the time your body wants to sleep -- your biological night -- you don't sleep as well or as long, setting the stage not only for fatigue, poor work performance and errors but also health problems ranging from heart disease and obesity to anxiety and depression.
Circadian rhythm also called as biological rhythm
is defined as oscillations in the biological, physiological, and behavioral function of an organism with a periodicity of 24 h.
Then in the mid-1980s the three laureates used fruit flies to isolate a gene that controls the normal daily biological rhythm
and showed how it encodes a protein that accumulates in the cell during the night and degrades during the day.
Their discoveries explain how plants, animals and humans adapt their biological rhythm
so that it is synchronized with the Earth's revolution it noted in a press release.
"(The three scientists') discoveries explain how plants, animals and humans adapt their biological rhythm
so that it is synchronized with the Earth's revolutions," the Nobel Assembly at Sweden's Karolinska Institute said in a statement.

The bulb is designed to synchronise with your body's biological rhythm

is no a new notion for psychiatry; as early as the 19th century, more and more data have proven the importance of periodicity in psychopathology.
I checked the Internet and found that last year, two researchers at Nagoya University-Tsuyoshi Shimmura and Takashi Yoshimura-made it to the international news because of their study of roosters crowing, and their conclusion that these birds do have a circadian clock, an internal biological rhythm
. The study was published in the journal Current Biology in March 2013.
In other cases, the timing of the activity is determined endogenously by an internal biological clock, which itself was previously set by a zeitgeber (an external oscillating environmental factor that entrains a biological rhythm
) (Bunning 1967; Danks 2006; Kostal 2011; Saunders & Bertossa 2011).
