Daily cycles refer to the natural patterns that occur within a 24-hour period, influencing various aspects of life. One of the most notable examples is the circadian rhythm, which regulates sleep-wake cycles, hormone release, and other bodily functions. This internal clock helps organisms adapt to the day-night cycle, promoting alertness during the day and rest at night. These cycles are not limited to humans; many animals and plants also follow daily rhythms. For instance, flowers may open in the morning and close at night, while certain animals may be more active during specific times of the day, such as nocturnal species that thrive in the dark.
