he Biological clock It regulates internal processes that set the body’s rhythm throughout the day. Although it works automatically, its operation has a direct impact on… Daily energy, appetite fluctuations and sleep quality. These differences respond to a natural mechanism known as circadian rhythms, and are key to the explanation Why are certain times more convenient for certain activities?
Science suggests that this internal system responds to external stimuli such as light, temperature, or feeding schedules. Therefore, when these factors change, The internal clock can also become unbalanced.
Specialists highlight that understanding these cycles makes it easier to explain why concentration increases at certain times, or why sleep appears at the same time, or why hunger intensifies at predictable times.
Throughout the day, the body responds to hormonal signals that are activated based on these rhythms. the The release of the hormone cortisol upon waking, A rise in melatonin during the night or a difference in the hormone ghrelin – which is linked to appetite – are part of this biological timeline. Thus, the internal clock does not operate in isolation: it coordinates multiple functions to maintain overall homeostasis.
One of The most obvious effects of the circadian clock are energy fluctuations throughout the day. The body has natural peaks and valleys that respond to the circadian rhythm.
These rhythms also explain why certain cognitive tasks are performed better at certain times. Memory, sustained attention, and complex problem solving often show a Better performance in the early hours of the dayWhile at dusk there is a greater degree of relaxation and a natural decrease in alertness.
This temporary organization It responds to evolutionary patterns associated with survival and adaptation to the environment.
The internal clock is also related to Physical performance. Body temperature reaches higher values in the afternoon, which enhances muscle strength and coordination. This difference explains why many people realize that it is easier to do this Doing physical activity in the afternoonWhen the body is more active.
the Circadian rhythms They are also involved in regulating appetite. Hormones such as leptin and ghrelin are released in very specific patterns, which determine at what time of day hunger occurs and when satiety occurs. These oscillations allow us to understand why nocturnal appetite tends to be more impulsive and less regulated.
The duration and timing of sleep also affects appetite. Lack of sleep increases the secretion of the hormone ghrelin Stimulates hunger and reduces the hormone leptinWhich enhances satiety. For this reason, specialists confirm that maintaining consistent rest schedules helps Appetite regulation To avoid sudden fluctuations in income.
At the metabolic level, the synchronization between the internal clock and feeding schedules is better Nutrient processing. Eating at times that are too far outside your biological rhythm can affect digestion, blood sugar, and overall sense of well-being.
