3. Disrupted Circadian Rhythms: The Internal Clock Goes Awry
We all possess an innate biological clock, the circadian rhythm, guiding our sleep-wake cycles. However, when this rhythm is disrupted, insomnia can become a lingering visitor. Travelers are well-acquainted with the impact of jet lag, a direct result of the circadian rhythm being thrown off its tracks.
Shift work plays a significant role here. Those working non-traditional hours, especially night shifts, force their bodies against the natural inclination to sleep when it’s dark. Over time, this constant juggling act can lead to persistent sleep disturbances.
Seasonal changes too wield influence. As the days grow shorter or longer, our internal clocks might struggle to adjust, leading to difficulties in both falling and staying asleep.
Screen exposure, especially during the late hours, can play spoilsport. The blue light emitted can suppress melatonin production, a hormone vital for sleep regulation.
Acknowledging the vital role the circadian rhythm plays, and taking measures to nurture it, can go a long way in addressing insomnia. (3)
