Turkish Sleep Medicine Association President Prof. Dr. Zeynep Zeren Uçar highlights a growing concern: the increasing prevalence of sleep disorders, notably ‘social jetlag,’ among young people. This phenomenon arises from a disconnect between an individual’s natural biological clock and the demands of their social life, leading to significant health consequences.
The Impact of Irregular Sleep Schedules
According to Prof. Dr. Zeren Uçar, an irregular lifestyle is the primary driver of social jetlag.The inconsistency between social and biological rhythms creates an imbalance, which experts refer to as ‘social jetlag’. Young people are particularly susceptible, often staying up late and attempting to compensate with extended sleep during the day.
This pattern disrupts daily life.School and work performance suffer, and the body and brain are deprived of adequate rest. It’s a hidden danger, especially prevalent during adolescence and late adulthood, affecting an estimated 30 to 40 percent of individuals aged 16 to 22.
Why Can’t They Sleep When They Try?
Individuals experiencing social jetlag often find it difficult to fall asleep even when attempting to maintain a regular bedtime. Their sleep schedules have become so disrupted that their bodies struggle to adjust. Many patients report going to bed at a reasonable hour (e.g., 11:00 PM) but still finding themselves unable to sleep until late into the night, subsequently waking up late the following day.
The Biological mechanism: Disrupting the Sleep Clock and Melatonin
This chronic disruption fundamentally alters the sleep schedule within the brain. The body’s natural production of melatonin,a hormone crucial for regulating sleep,becomes distorted,leading to a ‘phase shift’. This creates a vicious cycle: the individual struggles to maintain a normal social life, their business life suffers, and they become increasingly isolated.
understanding the Science: Melatonin and Circadian Rhythms
The human body operates on a roughly 24-hour cycle known as the circadian rhythm. This internal clock regulates various physiological processes, including sleep-wake cycles, hormone release, and body temperature. Melatonin, produced by the pineal gland, plays a key role in signaling to the brain that it’s time to sleep. when sleep schedules are irregular, melatonin production becomes erratic, disrupting the circadian rhythm and leading to sleep disturbances.
