Which of the following is NOT typically a consequence of insomnia?

Increased motivation is not typically a consequence of insomnia. When individuals experience insomnia, they often face a variety of negative effects on their mental and physical health due to a lack of restorative sleep. Insomnia can lead to a diminished ability to concentrate and manage tasks, resulting in a decrease in motivation rather than an increase.

In contrast, poor memory, irritability, and headaches are commonly associated with insomnia. Sleep is crucial for cognitive functions, and insufficient sleep can impair memory consolidation, making it difficult to retain information. Additionally, sleep deprivation can lead to mood disturbances, such as irritability and anxiety, further impacting daily functioning. Headaches can also occur due to a lack of sleep as chronic fatigue can contribute to tension-type headaches or migraines.
