Generation Z, encompassing those born from 1997 to 2012, stands out as the most sleep-deprived generation. This trend is fueled by their dependence on digital devices, social media, smartphones, and the demands of online studies and jobs, which keep them awake late into the night and disturb their natural sleep schedules. The consequences of this sleep disruption have profound implications on their brain health and overall well-being.
The Science of Sleep and Cognitive Impact
Sleep is crucial for cognitive repair and eliminating toxins from the brain. As sleep deepens, the brain transitions through various stages, including alpha, beta, theta, and delta waves, essential for vital functions. When Generation Z lacks sufficient sleep, these processes are compromised, decreasing memory, concentration, and overall cognitive abilities.
Insomnia is a prevalent issue among Gen Z, contributing to long-term health problems such as weight gain, increased blood pressure, diabetes, and mental health concerns like depression and anxiety. Just as regular nutrition is vital for the body, consistent sleep is critical for brain health. Studies reveal that lack of sleep affects the brain’s white and grey matter, leading to antisocial behaviour, mood swings, decreased patience, quick anger, and reduced creativity.
Alarming Trends and Statistics
In North America and Europe, decreased productivity is a significant concern among Gen Z due to insufficient sleep. A 2018 Journal of American College Health study reported that 60 percent of college students scored poorly due to inadequate sleep. Likewise, a 2019 Journal of Behavioral Addictions study found that 20 percent of teens underperformed or faced challenges due to smart device addiction. According to the National Center for Education, 5 percent of 16 to 24-year-olds have left school due to sleep problems and device addiction.
Further statistics from Canada in 2023 indicated that 43 per cent of Gen Z aged 18 to 24 suffer from chronic insomnia. In Bangladesh, increased screen time among youth has led to significant sleep disturbances, as noted in the 2022 Journal of Sleep Research. The rising trend of late nights and difficulty waking up is prompting American educational institutions to rethink morning start times, with the Journal of the American Academy of Sleep Medicine reporting that 70 per cent of students do not get enough sleep during the weekdays.
The Cycle of Digital Addiction and Sleep Deprivation
Digital addiction compounds the issue, with the brain signalling the eyes to check digital devices every 96 seconds, even during sleep periods. This constant interaction with screens diminishes the depth of sleep, making restful nights elusive for Gen Z.
Strategies for Recovery and Hope
I’ve found that addressing these sleep issues involves a holistic approach, incorporating nutritional foods, herbs, supplements, and techniques like meditation and breathing exercises. These strategies aim to enhance the cognitive power of the prefrontal cortex, improving decision-making and
impulse control. By restoring their circadian rhythm, young people regain mental clarity and freshness.
Despite these challenges, Generation Z holds incredible potential. They can harness their capabilities to achieve great things with the proper support and tools to overcome sleep deprivation. Addressing screen time habits and prioritising good sleep hygiene are crucial steps in empowering this generation to reach its full potential.
