What is suggested to be a common outcome of insufficient sleep according to the text?

1. a. Increased energy levels

2. b. Improved concentration

3. c. Elevated irritability

4. d. Enhanced memory

The correct answer is: c. Elevated irritability

The outcome of elevated irritability as a common consequence of insufficient sleep aligns with research findings on the impact of sleep deprivation. Lack of adequate sleep can affect mood and emotional regulation, leading to heightened feelings of frustration, irritability, and stress. This is because sleep is crucial for various cognitive and emotional processes, and when it is compromised, it can disrupt the balance of neurotransmitters and hormones that regulate mood. In contrast, insufficient sleep typically does not lead to increased energy levels, improved concentration, or enhanced memory, as these abilities often decline when a person is sleep-deprived. Instead, individuals might experience fatigue, diminished focus, and poorer memory performance. Thus, the choice of elevated irritability accurately reflects a common and well-researched outcome associated with insufficient sleep.
