What can be a result of poor sleep quality?

Poor sleep quality can have a significant negative impact on both mental and physical health, leading to several adverse outcomes. One of the most concerning results is the increase in stress levels and cognitive impairment. Sleep is crucial for the body to undergo various restorative processes, and inadequate sleep can impair the brain’s ability to function effectively.

When a person does not get enough quality sleep, it can lead to heightened levels of stress hormones, such as cortisol, which may contribute to feelings of anxiety and stress. Additionally, cognitive functions such as attention, memory, and decision-making can suffer, making it more challenging to concentrate and think clearly. This deterioration in cognitive abilities is often observed in individuals who experience chronic sleep issues, highlighting the critical role that sleep plays in maintaining overall mental well-being and cognitive health.

The other options suggest improvements in mood, cognitive function, and emotional resilience, which are generally associated with adequate and good-quality sleep rather than with poor sleep quality. Therefore, they do not reflect the negative consequences that arise when sleep quality is compromised.
