Question
List 3 examples of circadian disruption and explain what is misaligned in each example.
Solution
-
Shift Work: This is a common cause of circadian disruption. Shift work, especially night shifts, forces individuals to be awake and active when their internal body clock is programmed for sleep. This misalignment between the internal body clock and the external environment can lead to a range of health problems, including sleep disorders, cardiovascular disease, and mental health issues.
-
Jet Lag: This is another well-known example of circadian disruption. When we travel across multiple time zones, our internal body clock becomes out of sync with the local time. For example, when flying from New York to London, your body clock may still be on New York time, causing you to feel tired when it's midday in London and alert when it's nighttime. This misalignment can cause sleep problems, fatigue, and difficulty concentrating.
-
Delayed Sleep Phase Disorder (DSPD): This is a circadian rhythm sleep disorder where an individual's sleep is delayed by two or more hours beyond the socially acceptable or conventional bedtime. This delay in falling asleep causes difficulty in waking up at the desired time. Here, the misalignment occurs between the individual's sleep pattern and the societal norms or expectations.
