Body temperature, sleepiness, thyroid function, growth hormone, metabolic processes, adrenal hormones, and the sleep hormone melatonin all cycle with daylight
The biological cycle that is approximately 24 hours long is called the circadian rhythm. It regulates various biological processes such as sleep-wake cycles, hormone production, and body temperature fluctuations. Exposure to light is a key factor in synchronizing the circadian rhythm with the external environment.
That controls sleep and wakefulness. It is the body's natural clock. It is a biological rhythm or cycle of approximately 24 hours.
Most thought of sleep.
Probably your circadian rhythm prevents you. Circadian rhythm is a person's biological clock; regular bodily rhythms (for example temperature or in your example wakefullness and tiredness) that occur on a 24 hour cycle.

Circadian rhythms govern daily variations in biological and psychological processes, such as sleep-wake cycles, hormone levels, and mood patterns. These rhythms are influenced by internal biological clocks as well as external cues like light and temperature. disruptions to circadian rhythms can impact overall health and well-being.
Humans have a circadian rhythm that controls sleep and wakefulness.
One can find information on circadian rhythm in the Music Making Today magazine. This magazine has a lot of different articles and information on this topic.
