• Whats the cyrcadian rhythm

  • Sources:

    Circadian rhythm is a natural, internal process that regulates the sleep-wake cycle and repeats roughly every 24 hours. It's influenced by environmental cues, particularly light, which affects this internal clock situated in the brain. Here are some key insights from the :

    1. Basics of Circadian Rhythms: Our circadian rhythms are controlled by the suprachiasmatic nucleus, a group of neurons in the brain that acts as a master clock. This clock aligns with external environmental cues like light and dark cycles, influencing various bodily functions, including alertness, sleep, metabolism, and mood 1.

    2. Mechanism of Circadian Rhythms: Every cell in our body has a 24-hour cycle of gene and protein expression influenced by these rhythms. Light exposure, particularly in the morning, helps synchronize these rhythms with the Earth's rotation 1.

    3. Impact on Sleep: Circadian rhythms play a crucial role in determining sleep timing. Besides the circadian rhythm, sleep is also influenced by sleep pressure, which builds due to the accumulation of adenosine in the brain 2.

    4. Temperature and Metabolism: Circadian rhythms also regulate body temperature, which in turn affects metabolism and energy levels. Aligning your schedule (wakefulness, exercise, meals) with natural light cycles can help maintain optimal metabolic processes 3 4.

    Understanding and aligning with your circadian rhythms can promote better sleep and overall well-being.
