Humans have a circadian rhythm that controls sleep and wakefulness.
The body's internal mechanisms control sleep and arousal through a complex system involving the brain and hormones. The brain's internal clock, known as the circadian rhythm, regulates the sleep-wake cycle. Hormones like melatonin and cortisol also play a role in promoting sleep or wakefulness. Additionally, neurotransmitters such as serotonin and dopamine help regulate arousal levels. These internal mechanisms work together to ensure a balance between sleep and wakefulness.
In medical terms, the sleep wake cycle, also known as the circadian rhythm, describes an activity cycle that loops every 24 hours. Most organisms have this type of rhythm.
It is called the Circadian Rhythm.
The rhythm that regulates the body's natural wake-sleep cycle is called the circadian rhythm. This internal clock is influenced by external factors like light and darkness, and helps to determine the timing of when we feel alert and when we feel tired. disruptions to this rhythm can lead to sleep disorders and other health issues.
