Mastering Slumber: The Science of Sleep and its Role in Health and Wellbeing

Circadian rhythms are roughly 24-hour cycles in the physiological processes of living beings. They are found in most organisms and affect various functions, including sleep. In humans, these rhythms are influenced by external cues, known as zeitgebers, such as light and temperature.

One’s circadian rhythm can be disrupted by factors such as shift work, travel across time zones (jet lag), and exposure to screens before bedtime. The blue light emitted by phones and computers can interfere with the production of melatonin, making it harder to fall asleep.

To maintain a healthy circadian rhythm, it is advisable to:

-Expose yourself to natural light: Especially in the morning, to help reset your body’s internal clock.
-Limit exposure to bright and especially blue light: In the evening, to promote melatonin production.
-Keep a consistent sleep schedule: Even on weekends, to reinforce your body’s sleep-wake cycle.
