• The first use of the word in English dates back to the mid-20th century, establishing its scientific relevance.

Biology

• Many organisms, including plants and animals, rely on circadian rhythms to guide essential behaviors, like flowering and hunting.
• The master clock in our brains, known as the suprachiasmatic nucleus, plays a crucial role in regulating these daily cycles.
• Disruptions in circadian rhythms, such as shift work, can lead to health issues like sleep disorders and metabolic problems.

Technology

• Modern technology, such as artificial lighting and screens, can interfere with our natural circadian rhythms.
• Wearable devices are now available to help individuals track their sleep and activity patterns to maintain healthy rhythms.
• Researchers are exploring how circadian biology can inform the timing of medication doses for maximum efficacy.

Cultural Practices

• Many cultures have traditional practices that align with natural rhythms, such as agricultural cycles that coincide with day and night.
• In some communities, nighttime rituals are deeply tied to the circadian cycle, influencing sleep and productivity.
• The rise of modern work hours often clashes with natural circadian trends, leading to discussions on work-life balance.
