How can caffeine consumption affect sleep architecture evaluated during PSG?

• A. It can increase total sleep time and reduce wakefulness.
• B. It can reduce total sleep time and increase wakefulness.
• C. It has no significant effect on sleep architecture.
• D. It can improve sleep quality.

Answer: (B)

Caffeine is a well-known stimulant that affects the central nervous system. When consumed, it blocks adenosine receptors, which are responsible for promoting sleep and relaxation. This action leads to increased alertness and wakefulness, making it more challenging for individuals to fall asleep and maintain sleep throughout the night. In the context of polysomnography (PSG), caffeine consumption has been shown to reduce total sleep time, as individuals often find it harder to initiate and maintain sleep after caffeine intake. This can result in increased periods of wakefulness during the night and a reduction in the overall efficiency of the sleep cycle. Furthermore, the presence of caffeine can disrupt the typical progression through sleep stages, affecting the architecture of sleep by decreasing the duration of deep sleep and REM sleep, which are crucial for restorative sleep. Understanding the impact of caffeine on sleep architecture is important for sleep clinicians as it helps in evaluating patients' sleep disturbances and tailoring appropriate recommendations or interventions for better sleep hygiene.
